Service brakes
- What is wrong
- General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
- Risk
- Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
- Remedy
- GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1‑800‑630‑2438 or GMC customer service at 1‑800‑462‑8782. GM's number for this recall is N192261050.

What 2019 GMC Yukon owners say
Most recent owner complaints, unedited.
During normal acceleration on the interstate entrance ramp, the vehicle stuttered and continued on seemingly without issue. Within a few minutes, I noticed the check engine light flashing and fluctuating oil pressure, and I drove cautiously to the closest mechanic shop a few miles away. The code (P0307) indicated a cylinder 7 misfire, and I was referred to the dealership for further diagnostics. The dealership determined the lifters failed resulting in damage to the camshaft, which they reported is a very common problem with the 5.3 L engine. The repairs were quoted in excess of $11,900. This sudden failure at highway speeds poses a safety risk to the motoring public. Furthermore, the consumer should not foot the bill for GM's manufacturing defects. This information is provided in the hopes that a recall is initiated.
Lifters failed
Yukon would not idle without turning off on its own. Check engine light came on. Took it to my mechanic. Check engine light was flashing which indicated an active misfire. A running compression test found little to no compression from cylinder 6. Further investigation found that cylinder 5 had been repaired in 2022. Mechanic recommends engine replacement.
My wife drives this vehicle to work, it has started to experience reduced engine power driving on the highway causing her to pull to the side of the road due to no throttle to maneuver the vehicle in and out of traffic, leaving her on the side of the busy highway, we have now parked the vehicle after investigating problem there is a knocking noise coming from the lower part of the engine, after research of this 6.2l engine there are reports of the crankshaft and connecting rods seizing up and coming through the side of the engine block, knowing this we are hesitant to continue driving the vehicle. We continue to make payments on a vehicle that we can't use and can't afford to make a engine replacement at the moment. Very frustrating to say the least, as expensive as these vehicles are we have lost faith in the gm name.
Vehicle shudders at acceleration at times making merging onto highways and passing vehicles dangerous.
The vehicle experienced a sudden and rapid mechanical failure of the 6-speed automatic transmission (6L80 model) within a span of less than two weeks. The light did not come on until the transmission was past salvage. The failure escalated rapidly from initial minor slipping to a severe loss of vehicle propulsion. A loss of acceleration while driving poses an immediate crash hazard, as the vehicle cannot safely maintain speed with surrounding traffic or accelerate out of dangerous situations. The failure required towing and a complete out-of-pocket replacement of the transmission unit at 116,374 miles to restore safe operation. The manufacturer has failed to issue a safety recall despite widespread failures of this component causing unexpected power loss on public roadways.
Transmission is acting funny. Stuck in low gear /not shifting at low speeds. Vibration sometimes at higher speeds when shifting gears. 8 9 10 gears.
I was driving home on the interstate from vacation and I was set on cruise control it was 1 am so not a lot of traffic was on the road thank god. It could have been really terrible if lots of traffic was present as the engine just died without notice! The vehicle was decelerating nothing was working I could not speed up. I was able to get over to the side of the road. I got a notification on my phone that said battery critically low start vehicle to charge battery. Well nothing would start at this point. I lot all power seconds later. I thought that the cruise control was locked up and restarting it would reset it. I called roadside assistance to get a jump and that did not work. I got towed into an auto repair shop. They called me and told me that the engine is locked up that they drained the oil and found metal in it and metal pieces in the oil filter as well. They checked for leaks and said there was none that they could find. They said there was a recall but it was for the exact same symptoms that was diagnosed here but only starting with year 2021. Mine is a 2019 Yukon Denali with low mileage so not sure if all the other Yukons were aged out or already past engine death and that’s why they were not part of this but this should be included in with the open recall considering how everything is the same that is effecting this year that I have and they should pay for a new engine! Clearly the v8 6.2 gmc engines are having major issues I’m just glad I wasn’t going that fast and traffic was slow so I was able to get over safely before catastrophic things happened since there was no warning when this all happened!
Getting the valve ticking noise.
