My 2015 GMC Sierra SLT max tow has has a few mechanical issue,but also a couple of subpar factory design items. -15k Injector failed ( previous owner) -30k headlight upgrade: Morimoto XB HID kit, the retrofit store (factory lights were only good for driving in daytime) -35k radio upgrade: DSP, 45w Amp & 200w subwoofer, Kit by Kicker VSS ( factory “krackle” sound at 1/3 volume not suitable for $50k truck, now it rocks!!!) -70k A/C failed (factory design flaw in line set routing, see service bulletin) -80k A/C failed (dealer comped 2nd repair, loose hoses) -de-carbonized the DI intake twice (for effective fuel mileage, add intake decarbonize maintenance cost) Conclusion: beautiful and expensive like a mistress

[@ricardolanda6784]

I had too replace the radiator too that has been the only main issue. Mine is a 2015 gmc mine cracked in the corner too paid already good truck

[@JPandher]

Never had any good luck with my Sierra. Trans at 223. And a lot of little nitpick problems like bad grounds

[@mazda2284]

i have 2015 GMC sierra Denali , 64k miles dropped #4 lifter . if you have one disable the AFM / DOD system ASAP and if you ever have to repair it just do a full mechanical delete of the AFM system . having to rebuild the top end at 64k is upsetting . cam , lifters , springs , push rods , oil stoppers , basically rebuilding the heads , at least when im done it will have more power and the stage 2 cam will sound nice , best part is i wont have to worry about the afm system killing it ever again .

Sir, I feel for you. You pay good money for a new truck that you just want to sit back and enjoy and not wonder will today be the day when the next major issue arise. I love these new Chevys and GMC trucks and would love to get one but man, the heartache these trucks are giving their owners make me head for the hills...

[@justinh8055]

100 percent the good news is my 2021 has been excellent, good enough so that I recently ordered a new 2022 Yukon.

[@86Chevymontecarlo]

Good to know! Hopefully you will have many years of good driving!

[@alannilsson6509]

I am looking at a 2017 now! So glad I found your video. I will be digging further now on GMC Sierra issues.

[@Mason-to9fv]

Don’t do it get something else

[@thesonorandesertangler]

Get a pre-2007 otherwise you'll get a shitty truck

[@jacobsebastien3910]

You need a RAM

[@Mikey-wf9py]

Just got a 16 Silverado it's absolutely mint it runs and shifts so mint so maybe he repaired things already idk the Carfax report isn't specific enough but we'll see I guess....... Now that you say that my lines are dirty too like they when a fluid gets on it and then the dirt sticks to the fluid that's what it looks like now that you say it I just noticed that now they won't cover it even if you call I'm sure you already know by now unless they did cover it I'll be surprised it's a hose They don't cover hoses belts gaskets anything like that doesn't get covered because they're kind of a maintenance item unfortunately 65,000 yeah that's a little early for line but everything's built cheaper nowadays now you got me scared and I wanted to replace my lines now lol unless it's my power steering line which I'm not really worried about I've had trucks with wet power steering If it starts weak into the point where I got to fill it up yeah or it doesn't work yeah then I'll replace the lines but for now I'm running it

[@biggdawgg7455]

I have a ‘14 Sierra SLE z71 , and had to replace my transmission @ 82k miles . Had same problem with my trans lines @ the connection to trans cooler , all that was needed ,take retaining clip out , clean both female/male connection points & re-install & squeeze retaining clips a tad & re-install . Haven’t had any problems since (knock on wood) over all nice trucks . I have every option in it . Purchased Used as well .

[@hxdes3129]

6 speed tranny?

[@bobcook8576]

126k miles on my 15 onyx black slt crew 4x4 Sierra. Normal maintenance nothing more. 5.3 and 6speed auto is the safe bet for these trucks. Looking to put another 75k miles on her before any major repairs.

[@terrygmabrey3624]

1972 Chevy Cheyenne they still are running everywhere 3,500 new , now days 55 to 80,000 dollars and the trucks break all the time !!!!

[@johnbowhunter7676]

My 2017 had the rear main seal go at 50k miles, and transmission went at 92k miles...... thinking hard about a tundra now.

[@kylerbuican7945]

ford f-150??? tundra is much more realible so is the f150 the only two trucks i trust

[@peaceable263]

@@kylerbuican7945 Tundra for the reliability. F-150 for the mpg and interior.

2018 Silverado is the best Chevy out of the 14-18 years from what I was told

[@dodgedakota1]

@@jonnysnipes3123 I have 2018 it’s a big POS

[@jonnysnipes3123]

@@dodgedakota1 I have the 2018 LT so far no issues at 37k hoping I can hit 100 without any issues. I love the look of the truck but the truck itself just feels like glass. Feels so fragile which I dont like. I might just get a ram as my next truck

[@alexdiaz1512]

non stop problems with mine from dropping a lifter to ac going out oil leaks i have owned gmc trucks all my life and my 2015 is a beautiful truck but has been the biggest POS i have owned

[@damitbobby6677]

I got lucky with my 2014 so far. Has 195,000 and treated me well so far

[@garyh.8082]

I had a 14 Sierra SLE. Truck was a lease. Only problem I had was the passenger door lock solenoid failed at 6 months. GM replaced it under warranty. The other issue is the headlights are dismal at best. I installed a hid kit and that helped immensely.

[@davidporter7051]

I bet warranty didn't cover the repair.

[@justanaveragedude409]

I can't seem to find anything related to what my 2015 sierra is doing. When I drive for a little bit and stop, it starts making a clunking noise around the thermostat area. Anyone else have this issue? Have you figured out what it is/how to fix it? Thanks. Just bought it in February and thought my car issues were over for a little bit. But now I'm concerned.

[@daveellis5100]

Recorded horizontally:)

[@SilverDollarSaloon]

GM will not recall or repair defects for free unless it is in warrenty or the problem will cause harm to the occupants.The AC condenser leaking at a driver side weld is a common defect.

[@danarcotta1283]

I'm thinking that it's time that we all write letters to GM. They put out a shit product lately I've had an 84 4 wd GMC pick-up truck no real issues on these vehicles I've had a 94 trans am A 94 GMC pick-up truck A 3500 savanna van 2001 A 2008 Chevy express Now a 2015 GMC crew cab slt I've replaced brake rotors, a/c condenser, water pump, and now a transmission I bought it in 2018 with 50,000 miles. I currently have 137,000 miles on it and I'm considering selling it and looking at another brand. G M has failed miserably My wife has a 2013 genesis coupe with 95000 miles with ZERO issues.

[@v6wells]

Give it to me good looking truck

[@rivervisual7802]

All common failures. Add upper & lower ball joints,lifters,transmission problems and oil cooler lines leaking.

[@TonyArms17842]

All the transmission lines on their trucks leak. That’s been forever

[@meandmyself3007]

It is a good looking truck but reliable is a main issue

Kids raised by Yankees stick stickers anywhere they feel like. I believe in the belt.

[@mckricks1]

Not sure how you can be okay with having shifting issues at 65k miles...that's still a pretty new vehicle in that regard

[@shannonzittlow8462]

Watch out for the GM eight speed transmission they are not doing too well

[@theforestisdark9676]

I wanted a gm or chevy so bad but ima have to go with toyota or ford instead

More general motors junk that's all they build old Chevy trucks were the best

Buy a Toyota

Funny how you’re pissed off like I would be, but tries to be politically correct and say, “just a little bit disappointed!” I would be furious!
