Just bought a 2017 GMC Sierra SLT with just shy of 80k miles and found your KZbin channel. I am now terrified of everything and praying to god my truck holds up.

[@Bushwookie_18]

Lolol

[@TheSundaeDrive]

If you delete the afm, swap torque converters, and install an updated thermal bypass it should be good :) otherwise, yes be careful

[@detroitjohn4724]

please advise what the thermal bypass is all about. took AFM out of ECM, run amsoil 5-30, Amsoil trans fluid at 50K, have 90K in miles. Have 8.5 MM MSD copper spark plug wires, K&N air filter. otherwise stock. What happens to torque converter ? take it out only ? please advise. gotta make this truck last. Plain jane 2024 Silverado with 4 cylinder/turbo is 54K ! Last silverado lasted 405K including the trans. (lots of Amsoil oil/trans fluid changes) Present guy has 678,000 miles on it in Texas.

[@detroitjohn4724]

Should add that both trucks have finned, deeper pan for trans. Ist thing I put on truck.

[@ColonelEMHouse]

Bought my 14 Silverado new 8 years ago. It hauls 5k lbs every day. 230k as of now. Here’s what I’ve replaced: Transmission at 138k. Condenser at 80k. Compressor at 150k. AC hoses at 15k under warranty. Radiator at 220k. Vacuum pump at 200k. Starter at 200k. Suspension upgrade at 200k(not needed…but now it’s a bit taller) Upper and lower radiator hoses. Thermostat. Plugs and wires every 100k. Tires every 50k. Oil every 5k. Rear diff grease every 50k. Air filter every 25k. Trans filter and fluid every 30k. Added a catch can at 150k. Did a throttle body/intake sea foam cleaning at 150k. And now I run a range dod delete unit to stay in v8 mode…..to save my lifters. At times I’ve been mad at her, but overall I love her and appreciate her. The 5.3 is a fantastic engine. The fuel pump hasn’t failed yet. My last Silverado was a 98, and I replaced that fuel pump probably 4x between 80k and 275k miles. That was her Achilles heel. But the 5.3 vortec and 5.3 ecotec(afm deleted) are magnificent workhorses. I don’t love the 6L80 tranny. It runs too hot. It’s shift points in trailer mode especially when tranny is not yet up to temp is too hard. And despite my religious maintenance and careful throttling, the tranny doesn’t hold up. But I’d buy it again. Love my truck. And I named her AC Pro after fixing the AC system multiple times. Lol. Keep on truckin

[@TheSundaeDrive]

Good summary - I feel the same about my truck and engine for sure. Hopefully it keeps going for you!

[@regould221]

I always thought the shifting sucked on my 6L60 transmission. I changed the fluid to Mobil 1 Synthetic LV ATF HP even though it wasn't recommended for the 6L60 and things improved. The Mobil 1 Synthetic LV ATF HP is recommended your the 6L80. Have you tried it.

[@ColonelEMHouse]

@@regould221 I haven’t, but I will. Thanks fir the recommendation. I’m running amsoil atf right now. The transmissions on these trucks in my opinion are under built and troublesome to service. When I buy another transmission or new truck, I’m gonna tap in a drain plug. More frequent drain and fill could help these a lot. The bolts coming on and off for drain and fill tranny fluid has resulted in one transmission pan bolt female thread breaking down. And I don’t crank in her. I don’t even torque it as high as spec cuz they are small with fine threads. And the exhaust has to be manipulated to get the pan off. If there was a tranny oil plug, it wouldn’t be a big deal.

[@rapidride2]

Damn. I'll choose to take emotion for my truck out of it and consider that a huge financial loss over the course of new purchase and ownership.

[@burtreynolds781]

Did you do the thermal bypass with superior solution?

[@tsgtjk]

And a huge thank you talking about the lower driver side dash rattle. It has been driving me crazy and I am going to fix it tomorrow.

[@TheSundaeDrive]

You got it! It is annoying for sure!

[@mexifin]

I own. 2014 - 5.3l, a few recalls nothing too bad. I have replaced the fuel pump after 4 years of driving in North Western Ontario winter weather. Installed a new one. With a big blob of grease on top of sending unit and fittings. Replaced both valve cover gaskets. Passenger side air actuator was a few teeth out.rear passenger door wire was broken (window did not go up or down). Leak around the satellite antenna. And purchased Range Technology DOD. 2017. I have 190200 kms So far so good.

[@TheSundaeDrive]

Glad it is holding up for you with minimal issues!

[@kraemerdustin]

I had my compressor go out at 85k miles recently. And glad I turned it into a “race truck”. Swapped out my cam heads intake throttle body, torque converter and 550 hp rated clutches in the trans, and long tube headers . Did the thermostat delete and added a trans cooler trans temp runs around 135 cruising and on the gas 145

[@a.t1313]

Was looking at buying a 2014-19 Silverado or Sierra, but these videos portraying them as POS Moneypits has scared me off...Thanks.

[@TheSundaeDrive]

Mine has not been a money pit for more thankfully but I have done a lot of preventative work. I do know a lot of people have these for a long time without significant issues but your mileage may vary

[@gardner619works]

Saw you just uploaded trans modify and upgrade cooler video and it disappeared. Looking forward to seeing it back up. Great and helpful videos! Thank you

[@TheSundaeDrive]

It will be back up! We found an error we need to fix but it will be up for sure

[@etspaulding]

Great job again! I got my truck used with 83k in 2019, 2015 Crew Cab z71 6.5' bed. I had the brake pump failure and error message when I was driving home from the non-gm dealership where I bought my truck. It felt like no power brakes and for a big guy trying to stop a big truck with manual brakes, it took all of my 250lbs on the pedal. Quick internet search while sitting in a parking lot led me to the TSB and recall for this exact issue. Took it to the GM dealership the next day and they got me right in and immediately replaced the brake pump. While they were at it they reflashed the electric power steering programming, too, for a recall I wasn't even aware of. All of the work was done under recall and cost me $0. I wasn't aware of the airbag issue, so I'll have to look into that one. Thanks again!

[@TheSundaeDrive]

Glad you were able to get it stopped safely and they took care of you!

[@jeffwoolyhand9759]

It calls me an accident with the brake failure

[@the_langss]

Thanks for the Video....As of 12-29-21, no parts available to do the Side Airbag Recall, according to the Dealer I had do my last oil change. I was aware of some of the issues you addressed from watching Scotty Kilmer Videos...I do really appreciate you making these videos.

[@TheSundaeDrive]

Oh man. That's crazy. Good to know. Hopefully they get them in soon

[@the_langss]

I should probably add that this was not my first attempt to get the "Recall" accomplished. I called twice before, once right after I got the letter from Chevy, and then again a few months later. I even asked when I made the appointment to get the truck serviced if the "Recall" could be accomplished at the same time and was told yes. Not the first time I have had the "Recall" run around......Also other Dealers(who I won't use)also said the do not have the necessary parts at this time.

[@Kendye6]

Great video - thanks for sharing fails owners have dealt with. I'd heard about the fuel pump, starter, and lifter issues - everything else was new to me. The only issue I've had from this list was the overhead storage coming loose - happened to me last year on the off-road beach in Outer Banks, NC. Lucky screws were loose and easy to find, tricky enough finding where to re-install, but was able to fix relatively quickly. A bit of blue loctite never hurt anything Bought 2018 LT Z71 DC brand-new, 4/20/18 - hits 4 years in a few days - low mileage (32K), 5.3L, daily, few road trips (500-1400mi), leveled w/ 33" Nitto RG, Fuel 17" Rebel +12 offset, Eibach Pro-Truck Level/Lift (~3"), MotoFab UCA, Zone Add-a-Leaf, Borla S-Type, S&B Intake, JLT Separator, Bullydog tune (+AFM Delete, speedometer adjustment), Anzo Plank Headlights, Spyder LED Taillights, BedRug full liner, Bedslide black-edition, American Tonneau roll-up, Dee-Zee side rails, Weathertech floor liners/underseat storage, fluid undercoat for winters + Blizzak on OEM 18" alloys). Couldn't be happier with the setup - it's complete multi-purpose, designed to last. Not a single thing has broken, nothing replaced aside normal wear items (oil/air filter/wipers/fluids), original battery/brakes, 2 recalls (no issue w/ my truck) taken care of by dealer. I'd happily buy this truck again. I I have any of these fails moving forward, not too concerned as none of them seem too difficult or expensive to take care of but good to have an idea of what will fail.

[@TheSundaeDrive]

Definitely a good truck and most issues are pretty easy to fix. Just the lifters and transmission are a bit more expensive to take care of. No plans to get rid of mine

[@burtreynolds781]

How’s your transmission temp?

[@Kendye6]

​@@burtreynolds781 Stable. Just turned it on and it was around 210 (dead center of gauge). I think it usually runs a bit closer to 200 but not quite sure. Rarely get above the 210. Have no changed transmission fluid yet (34K).

[@burtreynolds781]

@@Kendye6 my 2017 trans temp is around your temp also. Yesterday I had installed the superior solutions thermal bypass on , im test drive it hopefully it’s below 200 degrees

[@joeepperson1494]

Thanks for the video! I bought my 2014 silverado 1500 in June 2021. Haven't experienced some of these problems. But I did recently have to have my engine rebuilt. Another problem I have had is evap codes. Might be the fuel pump. But one thing that has happened periodically, my remote lock would stop working randomly, but would always line up when my TPMS would stop working as well

[@TheSundaeDrive]

I've had an EVAP code for awhile now I haven't spent the time to track down, comes and goes lol. That is strange about the unlock, no one else has mentioned that particular issue in the comments so far

[@timothyhamre6504]

I have a 2017 Silverado LTZ. Don't care about all this stuff, I LOVE this truck!

[@30002elimoises]

Love the info bro may our trucks last us till we decide to check em

[@TheSundaeDrive]

Agreed!

[@maxs5535]

2015 Silverado 5.3 owner with 100k miles. Only issue so far was one brake caliper went bad. One of the most reliable vehicles I’ve owned.

[@donaldverbeck1504]

Transmission went out at 95K miles, but my extended warranty paid for it! One quick thing for the BT music pausing; Assuming it is the same issue mine has, it is much faster to click radio really quickly, and then back to media. It works for me 100% of the time. Just remember to turn down the audio before going to radio!

[@TheSundaeDrive]

sorry to hear that but glad the warranty covered it! Stay tuned for the video we have coming out this week to keep the new transmission lasting longer. good tip with the radio!

[@TheLouisianan]

These new trucks really aren't reliable anymore. A transmission going out before 100k miles is insane. So is the fact my manual for my 2018 says in the manual that your first flush is at 90k miles.

[@timothypollauf6800]

Excellent videos that I finally had the time to watch. I bought my 2014 Silverado LTZ extended cab Z71 back in the fall of 2013 RIGHT before GM got greedy and raised the MSRP up over $2000, thus mine is one of the early builds. Currently sitting at just over 40k miles I've had very few problems with it. First thing I did was take it to my nearest RustChek dealer to have it annually (semi-annually in my case due to low mileage use) undercoated using the fluidic messy stuff, so that my truck & frame don't rust out which is very common on our trucks. Heck, there was already surface rust on the frame when I took delivery of it right off the dealer lot! Anyways, as soon as I got my first application of RustChek, my rear end started to "clunk". Was told that would happen as the petroleum based product likely got into my bushings and loosened things up under there. No big deal but somewhat annoying when turning tight or driving slowly over uneven terrain. Transmission is great so far BUT will likely have the torque converter changed out in the upcoming years before it destroys the transmission. Got rid of the factory 18" alloys and Goodyear rubber (bad dryrot already on them after just 8 years) and got me a set of 20" chrome off of a '16 Silverado. Spotless as far as corrosion goes, whereas the 18's were already pitted and corroding everywhere due to the salt/brine in our area. The only other issue which just happened this past winter, is that the drivers side seat NO LONGER heats up. The lumbar still does BUT not the seat. Not sure if anyone else experienced this problem. Will keep this truck for another 20 years or so or until I'm 6ft under! Just retired so who know which one will come first.

[@TheSundaeDrive]

glad to hear you have only had very minor issues with it! I haven't had any heated seats issues but probably a wiring or button failure. My truck has also been really good so far to me. I plan to keep it a long time God willing!

[@danielsmith8659]

You have no issues because you only have 40k miles. I would highly recommend putting the 158 deg tranny thermostat on it vs the stock 194 deg, adding a catch can, and turning off AFM with a range module or something similar. That tranny will cost you at least 5k when it goes…. So take care of it. Do not skimp on oil changes either .

[@devsihelp2730]

@@TheSundaeDrive one thing I’ve found out when it comes to the Bluetooth not playing sound . Instead of disconnecting and reconnecting Bluetooth . If you just make a call while on Bluetooth and hang up sound is right back to normal . Saves a lot of time .

[@kylemckinnon8468]

I got my 2014 Silverado used at 92k miles, I’m up to almost 115k now in the few months I’ve owned it. It is my daily and I’ve done the basic bolt ons (Intake and exhaust + Diablo tube and afm delete + catch can). Haven’t had any serious issues with it yet, but on occasion my rear diff will make a clunking noise as if the spider gears are grinding. Not a common issue but it does happen. I would attribute it to my winter driving habits, like seeing an unplowed empty parking lot and ripping some donuts or figure-8’s. Also the stock horn is an embarrassment to the truck, sounds like a clown horn! Per usual thanks for the great informative video, hopefully you don’t have to add more broken parts to this list!

[@arox1834]

I don’t watch horror, movies I watched this video 😂

[@mattpingel7742]

Great video!! Thanks for the info

[@TheSundaeDrive]

Glad to help!

[@GoldStandardTrains]

Brought my 2015 silverado in for the brake power loss issue recall. It still has the issue since bringing it in and them "fixing" it. Seems to only happen when doing slow multi-point turn maneuvers. I will most likely contact my Chevy dealer again to see about getting it looked at again, but for now I know it is still a possibility that it can happen.

[@TheSundaeDrive]

That's pretty annoying. Rediculous that they havent fixed it. Sounds like they should be swapping out the vacuum pump and maybe the line running up to the brake booster. See if oil is in that line and then you know it's bad

[@ryancampbell9432]

I removed my Vacuum Brake pump. Works amazing with the pump removed.

[@davidwhitman9609]

Recently hit 120,000 on my 2015 and I have had my first problems other than rusty frame from day one that was covered under warranty but not really fixed. Had a difficult time starting after fueling, was the fuel vapor purge valve. Starting to have a low hot idle and shutter. Twice have had code P06DD Oil pressure solenoid valve stuck closed. I changed the oil pressure sensor and am going to raise the idle with a chip re-programmer. A few times I’ve lost brake boost at about 5mph and had to stand on the petal to stop. Thanks for the video, I like the truck and would like to keep it.

[@rickeddins302]

On the screens where it randomly presses buttons or switches apps/freezes. I’ve found cleaning the screen works really well on mine. Idk if it’s oil from your fingers/fingerprints causing it but anytime mine does i just clean the screen with a microfiber cloth and the problem goes away. Hope that helps some of you.

[@TheSundaeDrive]

Good to know! Thanks!

[@jeepinjehosifats]

The same here. I found using a bit of isopropyl alchol on a micro cloth to wipe down the screen (especially near the very edges) works well. Windex doesn't always do the trick for me.

[@sparkygal665]

2003 z71, only major issue in first 125k were brake lines rotted, and squirrels eating wire harnesses. At 18 years, still have original exhaust, have only had to replace the starter, and rusted tail gate brackets. Been a great truck.

[@TheSundaeDrive]

They don't make them like that anymore sadly

[@mayckelrodriguez8461]

I bought a 2007 chevy silverado 2500HD with 30000 miles in 2014 and the transmission broke down at 100k.. Bought a new transmission and after 10k I started to have problems again with hard shifting it was a nightmare...Now I would say I'm a happy 2022 Ram 1500 with the 5.7 hemi and loving it..I would never ever going back to chevy..

[@rockycadieux4642]

I had a 2016 5.3 Silverado. I had torque converter replaced @ 40K on the 6 speed. I also had the new low temp trans thermostat installed . I had installed a catch can when new. I used the severe service guide and changed all the fluids as recommended. I also had the radio go to full blast until cooled when the sun was really beating in on the truck. Traded the truck in at 50K . General Motors customer since 1996, I liked all of my purchases, except for the Silverado. I the front brakes kept sticking and burning out the pads, I guess you have to get them serviced yearly or this is an issue. Sorry, GM lost me, and it sounds like I was fortunate from what you’ve been describing. Great truck to keep content on your channel 😢

[@jalvarez411]

The rear end clunk noise is common on these 14-18.5 year model trucks. The two most common fixes is to re-torque your rear Axle u-bolts and replace the leaf spring pad inserts. The leaf spring pad inserts that worked for me was to replace the four plastic outer inserts with the rubber ones that come on the lower leaf spring. This eliminates the friction/noise heard...pair this with a u-bolt re-torque and it should fix the clunk issue. But if you stand on the side of the truck and grab the bedside then shake the truck side to side and hear a clunk, thats a normal characteristic to floating Axle trucks. If the noise/play of the axles is too loose or too drastic then id be concerned there is a rear end issue.

[@Mr.Beastforpresident]

What did you torque the U bolts to?

[@jalvarez411]

@@Mr.Beastforpresident U-bolt torque specs are tighten to 59 lb ft, loosen 180 degrees, tighten to 59 lb ft once more, and finally tighten 120-140 degrees. When doing the torque procedure, you want to go through all 8 U- bolt nuts each time before starting next step.

[@OscyJack-]

Another culprit is often the slip yoke of the clunk is felt just prior to a stop. Add a little grease and generally good to go

[@nohemoglibin8677]

I tightened mine to many ugga duggas and it went away.

I don't understand why you make these videos. I know, I have watched them, my bad. But, I have a 2018 Sierra 100,000 kms, never had any of the problems you have made videos on. I just do the regular maintenance and just enjoy my truck. All vehicles have issues. But I do enjoy the other videos you make!

[@TheSundaeDrive]

I definitely agree that if you take care of the truck it will last as I do with mine but I do more than recommended maintenance intervals and still have had a some issues such as the hpfp, condenser, leaking cooling lines under 30k miles, and a few other minor things. My hope is to show everyone how to fix these issues themselves through our other videos :)

[@mazda2284]

lucky you , many of us DO maintain our vehicles and have problems , thats what these videos are for . you sure as heck would not have made this comment had you owned my truck !! seeing a comment like this makes me wish you have the same problem im having so you can experience what its like to have a truck with 64k miles have a lifter fail , bend a push rod and ruin your cam !

[@deanvanasse5279]

Great video thank you! My 2014 Silverado with 4 cylinder engine had crazy shudder between 6 & 4 cyl modes, put in aftermarket device to keep it in 6 cylinder, torque converter failed at 57K, warranty replacement, Transmission failed at 128K $ 6K repair : (. New transmission recently overheating (up to 275F in hills no load) not happy, need to look into cooler bypass & fluid upgrade. I have the at speed vibration you show evidenced on cup holders of armrest, I had the driveshaft balanced & they said it was fine-still have problem.

[@inthemoment805]

I think another discussion on 14+ Silverado that I’ve been researching is common (since my truck seems to have it) is p06DD……. Oil pump…… and how much of a pain and costly it is to replace. Seen other videos where the oil pressure sensor may throw the code. Replaced that, but nope….. so I’m assuming it’s the oil pump now

[@erickaelin5420]

Great video, Cliff! Glad to know if buy a truck one day, I have a son that can fix all the issues...Dad.

haha Thanks Dad! For sure. I'll know how to fix them ;)

[@zrdh55]

Good vidio my on my 16 the vacuum pump would not work at low idle, got me in a bind backing down a hill with a trailer,pedal went hard with minimum function, reprogramed and raised idle, also the head unit had a propensity to blink on and off and freeze. when I replaced my battery I guess I cleaned all ternminals and haven't had a probelm since

[@ips7125]

Wife's 2015 would not go into v4 mode. FINALLY with about 15 days left on factory warranty, they figured it out. Intake manifold was screwed down to much and cracked at factory. Over time the cracks open up and suck to much air. Put a new intake manifold and truck drives better than it did new!

[@tylernanney5357]

I have the rear clunk/pop like it clicks into place like you said in the video on my 2017 sierra 1500, can you please do a video on all the possible outcomes or describe possible outcomes and how to fix each one in a comment? Thanks!

[@kennblair9358]

I took my 2015 yukon xl 6l80e 6.2l into the dealer to make sure my tc was toast along with the rest of the transmisiion, it was. I bought it with a 110,000 miles and knew this was going to happen sooner or later and it made it to 142,000. I had a trans guy upgrade the converter and trans. good work. The question I have is anybody experiencing lower ball joint problems. the dealer told me they need to be replaced, no big deal I plan on replacing the whole lower control arm when I do all the shocks, struts and front coils. myself. For all it's QUIRKS! it gets 7 people to snow skiing and hauls 7 while towing a 6,000lb boat very nicely. Those are the only problems I have had. I did install a Range and I love it!

[@TheSundaeDrive]

I think they are pretty common to go. I'm planning to replace all of mine soon when I upgrade my shocks. Don't want it to leave me stranded. I'm at 123K and they are still holding up but have a long road trip later this year and don't really want to chance it.

2014 bought in 2016 with 30k miles. Here is all that has failed . All head and tail light bulbs replaced 3 full times around the truck. Fuel pump module at 60k. 2 cats and 02 sensors at 90k. A/c condenser at 90k. Radiator at 90k. Fuel pump at 95k. Battery at 100k. I have another bad cat, but I haven’t replaced it, keeps check eng light on. Started at 110k. Transmission at 125k. Wheel bearings at 130k. Upper and lower control arms, inner and outer tie rods at 130k. Transmission cooler lines at 135k. Rear drive shaft u-joints at 135k..”solved clunk issue”…. Even though I couldn’t personally feel any slack in them when turning by hand , the clunk stopped. Definitely forgetting a few…. But currently at 146k at 7 years of ownership and probably close to 10k in repairs. I did some of this work myself , so I didn’t actually spend all of this , but still …. Thousands of dollars. I’ve owned every 1/2 body style since 1995 until now except for the current one and I have never owned a vehicle with this many issues this early, and I maintenance my stuff very well. A big L for GM…… probably the most disgusting one to me is releasing an updated tranny thermostat 7 years after burning up no telling how many transmissions.

Great video! 2017 Silverado WT-1500-4x4, purchased new, western ny area, at 20,000miles/2020 had to replace all 4 brake rotors , hardware and pads due to excessive/premature corrosion which caused loss of brake performance and increased stopping distance, no help from GM.....

[@skyeking1]

I have a 17 Silverado LT in Western NY as well. I have just started experiencing the problems described in the Sundae Drive site. As far as the brakes go, I started installing ECB Brakes in my vehicles and found that it was money well spent. The pads and rotors are far superior to any that are available including GM replacements. A slight premium in cost but worth every penny.

[@kaylazalansky5715]

Also there is most likely a special coverage warranty for your rear clunk noise , the dealer will inspect the leaf sprint brackets and grease them then road test it, if the noise persists they will replace the brackets or whole unit. Same goes for the vacuum pump even after the recall has been performed it’s just a reprogramming event and the vacuum pump will still fail at one point so they can replace that as well under a special coverage warranty.

[@garycamus6421]

No special coverage for this. U bolts were tight so I lubed the spring clamps/brackets rather than wait for them to do it. Lasted 3yrs so far.

[@lyndseydemoss1046]

I bought my 2015 about 7 months ago with about 60,000 miles on it. Very clean truck and so far has been running great (but now you're videos have make me paranoid 🤣🤣). The main and most annoying problem has been electrical based. The first time, I got warnings for Stabilitrak, trailer brake and all kinds of things. The main screens went out, the radio would come on at full blast and couldn't be shut off, and then it did stall a couple of times. It showed 17 codes. After a process of elimination, we replaced the battery (which tested out fine, but decided to try it). A couple of weeks after, the trailer brake system light coming on (like 16 times in a row). No codes that time, but lower than normal voltage. So then we rebuilt the alternator and the positive battery cable. Currently driving it and now the radio is flipping screens both on the main screen and the dash info screen. I've had it at my regular shop, but taking it to the dealership to get the airbag recall done, so I'm going to trip down that rabbit hole with them. But does anyone have any guidance? I love this truck in a lot of ways... But I upgraded from a Gen 10 F-150 because I was hoping to minimize some of the maintenance bills ... But dear lord this is stupid.

[@TheSundaeDrive]

It is a great truck for the most part once afm is deleted and you take care of the transmission. Your electrical issue are most likely a combination of bad grounds and terminals going bad in the rear module by the spare tire and the engine bay fuse box.

The radiators on these trucks are undersized in general. I know GM made the TSB about the radiators for the 14s and 15s, but my 2018 had a radiator leak at 35k miles and it wasn't even covered under the powertrain warranty because it only extends to the water pump and thermostat. The radiators look like they belong on a car with a V6 maybe, but not a 5.3. Most people on forums that had these issues (recurring) on their 14s and 15s got aftermarket radiators that weren't flimsy and never had the issue again.

17 tahoe ssv 98k, the steering shaft as it goes through the firewall can make some noise/vibration if whatever it rides up against gets real dry and worn. Some silicone lube (the same stuff for brake slide pins) fixes that up for a good while. When it's just the right amount of cold outside the first push of the brake pedal makes an almost whistle sound thats hard to put into text. It's fine for the rest of the day almost every time so I'm assuming something to do with the brake booster. And another cold problem is the bendix gear of the starter likes to stick if it's too cold and grind the flywheel. Those are the few things that came to mind that I didn't see in the video.
