It's leaking everywhere! CAR WIZARD shows most common leaks on 2015 GMC Yukon

[@XGamesJ6]

I've repaired this before by cutting the metal tube before the rubber hose crimp. Using a flare to just slightly bubble out the end of the tube, then sipped a hose over that with a clamp and no problems since. But most shops will often elect to just replace the part with a complete new part because then you can be sure it won't fail, and if it does it's covered by a warranty.

[@mph5896]

Yeah, just replace the entire line set. I priced a buddies truck, engine oil cooler lines and trans lines combined were $150 for GM parts. Toss them on in a few hours and its good for another 100k.

[@ecannon649]

I agree I have fixed hundreds of trans lines by just cutting the crimps off and clamping on new hoses. The key for me is being able to get to the crimps, If not it will need a new line set.

[@danielkapp9468]

Wizard, after you use the oil spill rags I recommend investing in some betonite Quick-Gel just a bag or two as it will last you a long time. It comes in a 80-100lb bag (about $7-$10) in a powdered form (think flour) and you can throw just a small amount and it will pull up the stains with minimal scrubbing with a push broom, this works on even old oil stains and after your done it can be disposed as trash. Best part is there are no chemicals it's 100% natural.

While some of my older GM stuff did have minor leaks I have / had zero problems with leaks, on the modern stuff. One thought, I do ALL my own PM and when I change the oil / filter on the transmission (for example) I do replace the gasket(s).

[@universalassociates6857]

When there is an oil leak that drips onto the splash shield the leak can go unnoticed for quite a while. Otherwise the owner would be more likely to see the drip in the driveway or street and get it checked out. So here's a design that on the one hand, can protect the exposed engine parts from water, salt, etc... but can result in delayed maintenance.

[@newman5924]

Valve covers on a 5.3L are quite labor intensive?? I did mine on my 2010 with very little trouble and have essentially NO mechanical ability. My tranny lines also started leaking after 4 years on my 2010....took to the shop for that and they've been good in the 9 years since.

[@Kuzican01]

There is also an upgrade that should be done for the 2014 on up offered by Superior solutions on the transmission thermostat part number A104996-5k for the 6L80/90E. This helps with knocking down the temps on these transmissions with the built in thermostat that bolts on the transmission line you showed in video. Mine went from 201 degree temp down to 175 degree.

[@GenderSkins]

The only time we had that issue of transmission line leaking on the old square body Chevy trucks, was when those steel lines would either rub the frame or each other. Was not uncommon to see someone put a piece of rubber hose on the transmission lines to keep them from rubbing something.

[@hotpuppy1]

I'd be concerned about the direct injection, lifters and variable cam timing stuff causing $1000's in repairs in the next couple of years. A couple leaking lines isn't what I would worry about (they STILL need to be fixed though). GM isn't doing us any favors with a lot of their designs. What with the 3.6 V6 that needs engine out for timing chain, the 3.0 diesel that has an oil pump driven by a belt on the rear of the engine that means trans out to change at 100-150k miles (timing chain also on the rear.) It seems anything newer than 20 years old is a money pit of electronics/mechanical garbage. Ford/MOPAR/GM, doesn't seem to make any difference (or many foreign for that matter). Too much to buy the vehicle new. Too much complexity. Too much expense to fix. No wonder there are those companies advertising extended warranties, assuming they actually pay out.

[@mph5896]

Timing jobs are expensive and not fun, but most mechanics can do them. The thing that really takes down new cars is electrical issues. And the mechanics that are out there, I would bet 75% of them can't find/diagnose the problem without trying to throw parts at the problem. This is partial due to low times allowed for diagnosis and lack of training. I do some consulting for a landscape business. They call me up when nobody else can figure out the issue. I'll work until its fixed regardless of time. Spent 5 hours a few weeks ago finding 1 broken wire turning the truck into a paperweight. Another I spent 3 days on tracking down an intermittent can bus network short. There alternative was paying a shop $1500 for a diagnosis, and in their words "Would you like us to keep looking, we are no further along than when we started". Or tossing a front diff shift motor at a truck that had a broken pin in a connector.

On almost every make these hoses fail and it's a byproduct of the rubber itself heat cycling. I see the same issues with oetiker style clamps that are used on some other vehicles. Truthfully 125,000-150,000 miles without leaking is what should be expected of a rubber line regardless of type which is just enough to have it last past the 100k mile mark so they list them as lifetime items and keep them out of routine maintenance tables lowering the published expected maintenance costs. Personally I wish we had more realistic maintenance tables and expected service life for the parts but that doesn't get you top rankings in articles showing low maintenance costs.

It's best to have the car you own now checked every six months or less for anything that needs to get replaced. Preventive maintenance prolongs the agony of breakdown. Unless you're tired of the years, you have driven the car too long. Remember, don't expect a high return selling your car.you lost that driving off the lot when you bought it. Either way you have to buy what you want and keep it.

While these are common problems with GM trucks, Id venture to say they are less a faulty component and more a part that is less tolerant to abuse and neglect than the rest of the truck (which is quite good, as you've said) All my rental GM trucks, from 2011-2018, as well as my personal 2002 Tahoe have lots of milage and none of them leak from the "common" places. They get used hard, tow a lot and none have less than 150K miles. Regular oil changes with synthetic and OEM filters, coolant flushes before they are due, big trans coolers and fluid changes.....all these things keep the heat down and the fluid additives percentages up.....both vital for keeping gaskets, hoses and seals pliable.

[@alb12345672]

F150s have a joint in the trans line that can suddenly separate and dump all the fluid in seconds. Trans ruined. Lots of guys are practically in tears on forums. I did mine over with bulk hose.

[@golferal]

Weeeeeeezard! I had a 2016 Yukon XL that was still going strong at 164K miles when it was totaled in an accident. The only mechanical issue I had was the transmission at just under 100K (replaced under the extended warranty) and the driver's side motor mount. It was a very reliable vehicle! After my 2016 was totaled, I bought '21 and '22 Yukon XLs and they are absolutely amazing. SUCH an upgrade over the previous generation!

[@davidellefson4556]

Just the transmission huh? 100k miles GM junk

[@golferal]

@@davidellefson4556 Yes, the 6L80-E is not a very stout transmission, although the dealer did say that they don't see many fail quite that early. I'm hoping the 10 speed in my new Yukon is a little more durable!

[@mph5896]

@@golferal Yeah, the 6l80 is a 100-120k mileage transmission. They work well when they work right. Expensive to rebuild as well for parts.

[@therealpeterburke]

180k on a 2015 Suburban LTZ here. Apart from the typical frame rust we get up north, there is really wrong with it. Brakes replaced, fluids changed, new tires, etc. No leaks anywhere. I may need a new transmission eventually as the clutches are starting to get a bit loose. Lots of miles on it. Had a misfire once and replaced the plugs (a few hours of cursing to get to #8). Those plugs were original at 175k. Original owner didn't take care of anything and it still runs fine. Zero oil consumption and 21mpg highway.

[@reed785M]

@@golferal the 6L-80 is absolutely a stout transmission. Flukes happen, my 6L80 went 200k and was still going strong when I sold it, and I thrashed on that truck.

[@captinbeyond]

It's amazing what one of these 2015 Yukon's would be selling for used today, even knowing the repair possibilities and having leaks. And also with 150k miles, they'll want a king's ransom

[@georgebrown6329]

If i went to my local GMC dealership...what specifically would I ask them to replace as far as the leaks?

[@shekharmoona544]

I have a 2012 Jeep Wrangler and when I turn on the heat there's a burning smell. Not electrical burning, oil, transmission fluid or coolant. No lights on, no leaks. I checked the HVAC filter nothing there. The floorboards are dry.

Trans lines on my 2014 Sonic also leaked. Just got them fixed a few weeks ago

[@e66ninja59]

Can't decide between 2018 Suburban/Yukon XL or 2015 - 2017 Ford Expedition EL. Do I go with AFM/DFM problems? Or whatever problems the 3.5 ecoboost has. Which engine would win out in the long run? Some of these problems that can occur on both make my 2013 7 series look reliable. Unbelievable.... but I need a big SUV. Which one do should I gamble with?

[@ottovonbismarck7094]

Go with the GM, ecoboosts are harder to work on and a turbo is far more added complexity than V4 mode

[@e66ninja59]

@@ottovonbismarck7094 Thanks for the reply. I figured a little money to delete the AFM would be so worth it in the long run.

[@ottovonbismarck7094]

@@e66ninja59 the most critical flaw of new 5.3s are the AFM, guys up in New England have already put 300-350k on original motors, but they have had their AFM deleted in that time frame, be aware of 8 speed automatics, they have pretty serious issues

[@The98deville]

Have you seen the new Silverado pickups with a 4 cylinder ecotech motor? I was shocked the first time I saw that. Also GM has decided to copy Ford and use plastic oil drain plugs that will leak if you don't replace them when you change the oil.

[@waynemiller3845]

Hi I like your videos they are informative for the most part but just to take a flash light and look at inside of the wheel /caliper area and give a percentage of brake life left. I don't think that's a good enough inspection. I hope that's not what you do and send them on there way. I work on a lot of vehicles myself and have seen countless times that one side of the pads look good and the other wiped out.

[@Alex88302]

Why not just cut the crimp and the hose off and replace with a segment of new hose and good hose clamps? Seems like a waste if the hardlines are still in good shape and then it's actually serviceable.

[@quicksilver462]

That is totally possible, and probably something that I would do for myself for my own car, however, repairing, opposed to replacing an item are two different things, especially when it is commercial service. Repairing, or rebuilding a part or item takes craftsmanship, replacing an item not so much. If you were to repair a line for a customer, and the line leaks again down the road, who's responsibility is it when it fails? Bottom line, for a commercial repair business, there is too much responsibility at stake for a repaired part, as opposed to a part commercially manufactured, and then installed. Who covers the warranty and liability/damage/injury for a repaired part ?

[@crsp76691]

My 2017 chevy volt leaked oil from the pan a week after taking delivery. It took them 4 different times for them to seal it.

[@jameshall4385]

I do my own work and I just cut the crimps off and use hose clamps and high pressure oil line. Its way cheaper

[@ianknightley3310]

As a GM service advisor, I approve this message . Super common areas to leak.

[@thefordmaniac]

Bless your heart

[@jwelchon2416]

I think what happens is that GM buys a ga-zillion cooler lines at once. If they leak....well.....They are not going to throw them away. It's not a safety issue so on they go until they are all used up. I know GM did that with power steering pumps at one time.

[@leeterwilliger2303]

I bought a 2015 Sierra Denali in 19 with 75k miles. Had all this mentioned in coments done now at 88k. I bought the full service contract up. More than paid for. I don't think I'll own a modern vehicle without a warranty. Kinda sad.

[@gabejacobs9048]

that driver motor mount on the awd models is annoying to get to at first. screw that little shield

[@steveshoemaker6347]

That color on this truck in very beautiful.....Thanks the Wizards 👍 Shoe🇺🇸

[@christopherkoch6881]

I think several things you are missing in all this is that in the 1960's (my teenage years) and 1970's you rarely ever heard of a vehicle (car/light truck) going over 100,000 miles. Even today, you change out your Rubber tires by 8 years tops. So why would you expect other rubber items lasting 150,000 miles and more than 8 years? This is just normal maintenance - especially with 20+ year old vehicles being common with well into mid-200,000 miles on the clock!

[@joeshmoe8952]

I wonder if the newer GM trucks with the 2.7 turbo have this issue?
