Car was parked in front of our house and combusted in the middle of the night while we were sleeping. Car was exploding and engulfed in flames...completely destroyed via fire and the worst damage was in the engine compartment. Cause of the fire is unknown although based on research sounds like NHTSA campaign #14V007000 or 14V152000. Fire department extinguished the fire and police were on the scene.

Brakes don't work well when traveling at low rates of speed. Stopping requires brakes to be pressed to the ground and still may not stop. I have almost had several accidents even after having the issue 'repaired' last year. I've had the problem assessed at 3 different mechanics. I have had to throw my car into park to avoid hitting cars in front of me. Brakes fail while driving in places such as traffic jams, drive thru, school pick up, etc. This is a huge safety hazard and fear that my children may be hurt if this issue is not corrected by the manufacturer. Steering becomes nearly impossible when the brake issues occur. This is an ongoing problem for the last 1.5- 2 years. Also, the tail lights continue to go out even after paying hundreds of dollars for replacements.

On repeated occasions (from 2015 to 2019) I have experienced sudden acceleration at low speeds and sudden jerking motions. The transmission and speed controls are unpredictable and dangerous. This is hazardous and may result in a loss of control. I have also experienced numerous issues with the brakes including a stuck caliper at approximately 42,000 miles. I reported these issues and numerous other issues to GMC corporate, tustin Buick GMC only to be told that it was a software issue and things are satisfactory and safe. GMC contends that the vehicle is fine and declines to assist with issues. This is an ongoing issue. The date below is approximate. The mileage is approximate on all entries.

The 8 speed automatic transmission on my GMC Yukon denali has a slippage issue that has persisted in our vehicle for a while unresolved. GM has replaced torque converter, module and now they are claiming through dealer that the issue resides with at fluid. This slippage is bad because car jerks and sometimes hard. This issue needs to be addressed by GM as they know they have issues with this 8 speed at. The issue happens at stops and at slow speeds.

The contact owns a 2015 GMC Yukon. While at a traffic light or stop sign with the brake pedal engaged, the vehicle would shake and idle highly. The failure was experienced numerous times. The vehicle was taken to dick norris Buick GMC clearwater (18200 us hwy 19 North, clearwater, fl, (727-536-1967) and the motor mounts were replaced three times, but the failure persisted. The vehicle was taken back to the dealer several times and the motor mounts were adjusted and the transmission mounts were replaced; however, the vehicle continued to idle highly and shake while stopped. The manufacturer was notified. The approximate failure mileage was 19,000.

Vehicle drive train operates erratically in various operating situations and has extensive vibrations between 25-40mph; vibrations are worse in certain gears. Significant lungeing and jerking on shifting gears on acceleration particularly when not accelerating intensely. Most concerning: When decelerating after running at highway speeds and downshifting (I.e. exit ramps, highway service/rest areas), vehicle accelerates (after downshifting) and requires extensive brake pressure to slow and control. Taken in for service 3X at 3 different GMC dealers. Transmission has been reprogrammed 2X. 3rd dealer provided GMC technical service bulletin "#99-04-20-002I: Information on drive train clunk noise - (Nov 18, 2014)" and told it's 'normal operation' and is due to drivetrain 'lash' (aka gear slop or play). Paid $150 to be told "customer concern not duplicated at this time". simply find this hard to believe as the operations as described are readily apparent. In all seriousness: (1) the sudden jerking/slamming of gears on acceleration has been notice by several passengers not just myself, (2) the acceleration on downshifting is a huge liability as the increased possibility of rear end collision is significant and (3) no way is it 'normal' operation.

Transmission has been clunky and jerky from from purchase. The vehicle vibrates between 30 - 35 miles per hour when shifting. The vehicle lurches forward when accelerating as if it has difficulty down-shifting. The problem is present from simply backing up out of the driveway, modest speeds on city streets, or on the highway. When brought back to the dealer, they claimed it was a software issue and "refreshed" the software. The problem has not gone away and did not improve by this software correction. My internet research indicates that this is a common problem with the new 8-speed transmission for the 2015 Yukon denali and Cadillac escalade.

When approaching a toll booth on the mass turnpike, with several lanes merging, with the vehicle almost stopped, it downshifted to 1st gear and in the process lurched forward extremely violently to the point I almost crashed into the car merging in front of me-probably stopped short by six inches or less !!!

Our vehicle has a significant vibration in V4 mode when traveling between 45-65 mph and above. The vibration is also accompanied by increased cabin pressure. These issues are causing headaches, nausea, dizziness, and are further exacerbating my wife's multiple sclerosis. We also have a popping sound coming from the rear of the vehicle's suspension when turning that makes us feel unsafe. The vibration started right after we took delivery of the car and has only gotten worse. We bought the car in April 2015 and the issue continues unfixed to this day. The popping noise started about 3-4 weeks ago and it sounds like a suspension component. Our ac recirculating feature also does not work and it allows harmful exhaust smoke in.

Transfer case failure causing multiple other component / system-wide failures including advance safety features, engine power reduction, 4 wheel drive system failure, bluetooth connectivity failure, radio failure, traction control failure and more.

- Fresno, CA, USA

Very concerned about my 2015 Yukon XLT. The vehicle's gear shifted to a neutral of very low gear (not very sure) as I was driving down a long hill near birmingham, al. It felt like it went to first gear, but at the same time it did not slow the vehicle down, almost felt like the gear was grinding. The truck did not catch back into normal gear until the vehicle leveled back at the bottom of the hill. (it was extremely scary and worrisome ever since then, the transmission will not shift smoothly.

I have a 2015 Yukon denali and I was driving 65 on the highway and the engine shut down completely. A warning message said engine power failure. I had 4 cars and an 18 wheeler behind me at the time. I managed to put the vehicle in neutral and coast to the side of the road onto a median. It was towed to the dealership where they started trying say it might have been bad gas. Then I was told I cracked valve and they already had one other just like this, then 1 day later after a tech level 2 and a shop forum looked at it, and a conversation with a GM pac rep, GM approved a complete engine replacement! I was shocked. I've had the same 4-wheel drive issues everyone else has. I've also had A/C problems, steer wheel popping noises, sunroof loud wind noises. My seat shifts when I drive it. The A/C seats don't cool properly, which I found out when they put me in a loaner Yukon that worked fine. The speedometer gauge also didn't work for 2 days, which I have a picture of and received a warning ticket for when I was pulled over by an officer not knowing what speed I was going. I passenger step guard doesn't always retract properly. My unit was purchase May 2014 and was one of the first 4 X 4 units that was produced and has had constant problems. GM keeps denying a buyback, then no trade assistance, then now has offered an extended warranty. This particular vehicle I have is not safe for my family to be riding in. I can't trade it in or sell it to anyone else knowing the problems it has. The dealer won't even take it because they know the problem that they are dealing with.

When the vehicle goes into 4 cylinder mode and you hold the speed steady or give it a little gas it starts to vibrate you can feel the vibration in the steering wheel and on the front console give it enough gas to make it go into 8 cylinder mode the vibration goes away.

The new 2015 vehicle freezes up in full time 4WD mode and will not shift out. The dealer indicates that it is a "known problem by GM" and that they are "working on it". their fix at this point is to have you run the vehicle in 2wd mode which is an obvious safety issue during our winter months as it is then a rear wheel drive vehicle being driven on icy roads.the other fix is to run it in 4WD mode but turn it into 2wd mode every time you turn the vehicle off. Obviously, many drivers will forget to do this and therefore my family at times is just running it in 2wd mode thereby incurring a risky driving situation. Despite numerous discussion, I have not been able to get any information on when the vehicle will be fixed.

Vehicle has a terrible vibration. Has been to dealer 7 times, for a total of 4 weeks. A GM engineer has looked at it twice. They have replaced ring/pinion, driveshaft, axle.. tried it with 4 sets of tires/wheels. Last idea was to replace shocks, struts, sway bars with hand built parts, cut brackets off car and weld new brackets on. When liability was brought up, they changed their story. There is a larger issue as was relayed by engineer to service manager at dealership. Issue is with all 2015 Tahoe, Yukon, escalades. In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board. According to engineer, GM is keeping an eye on how many units they have to buy back, or trade for... if number is low enough, they will not make any changes to design. I would like to schedule a meeting next week to discuss this issue and the larger issue in person. Since they are refusing to buy back my vehicle, I am turning matter over to attorney.
