GMC bitch. Engineers that designed this Yukon Denali with 6.2 never turned a wrench or know what one is.

[testdepth]

Oil pressure sensor unit located all the way to the rear of the engine up against the firewall behind a useless plastic shield. It sits about 6 inches down on top behind a bunch of hoses.

Cam shaft sensor is located behind the crank shaft pulley that you have to pull off to get to it.

Crank shaft sensor is located directly behind the starter that you must remove to get to the sensor.

No fuel pump relay or fuse. This truck has a Fuel System Control Module located under the back of the truck under the spare tire. You must remove the spare tire to get to it and that is where you jumper out the pump to empty your fuel tank.

No access panel located under the rear seat to make it easy to change the fuel pump. You must empty the tank and then drop the tank to change either the fuel pump or the sensor.

2007 to 2014 plastic dash all cracked. You have to replace the $1000 plastic dash with no guarantee it won't crack or place a cap over the top for about $200.

Oil filled ****ing motor mounts. WTF was wrong with solid rubber?

****ing useless EVAP system that does nothing but cause problems.

EVAP canister filled with charcoal smaller than a grain of rice. When the canister fails all the charcoal pieces are sucked up into your tank, purge solenoid and lines/hoses clogging them.

Feel free to add on!

Yep you about covered it. But dont forget the passenger side heater blend door motor that you have to either pull the dash or get very creative to change.

For a lifetime mechanic I have made many a paycheck off their silly designs though. Not that they arent infuriating at times.

I was at the local GM dealership talking to a 30yr GM mechanic. He had the Sheriff's Department Chevy Tahoe engine torn down because the lifters had rotated and wiped the cam shaft lobes. It looked like someone took a grinder to three of them. The lifters are held in place by ****ing plastic holders. He said it's a common problem.

I can tell you that they haven’t gotten much better. I can also tell you they designed the 2023 mini duramax wiring harness a little “snug”. I can also tell you it can mysteriously break 150 miles after the warranty expires. I can also tell you that the repair is a cab off, $6000+ repair.

Go, you engineers, go! You’re killin it!

GM burned me once in the 90's... and they are still making garbage. Why anyone would buy anything they sell is beyond me.

There not designed for the average person to work on them.

Oh yeah....todays "Engineers" have zero phucks for mechanics.

Don’t forget about the ****ty weld on the top corner of ALL 2014 ac condensers.

I like 07 and prior gm 5.3’s only, anything after is pure trash.
Not much on the market that’s better, but I take my chances with ford. I’d rather pull the front cover and deal with phaser/tensioner problems on overhead cams rather than have to pull both heads and the front cover for cam/lifter problems on the gm and dodge v8’s.
