ENGINE, FUEL/PROPULSION SYSTEM
Twice in a five day span vehicle stalled out, acting like it is not getting fuel. Each time it took several minutes of trying to restart and getting below fuel tank to give it a couple knocks to get it to start. Both times there was atleast a half tank of gas. Each time the car was running well when it suddenly slowed down on its own, the first time I was on a busy street resulting in the need for a tow and I had my grand baby with me. The second time it was an isolated road and surprisingly I had cell service to call for assistance. The tow truck driver told me he thought it was the fuel pump. I looked up my vin but it isn’t listed as one of the affected vehicles in the GMC Yukon recall, however it certainly seems like it is. I had no warning of any type with each incident, the car simply acted as if it ran out of gas. I have an appointment with a local garage. Additionally when this happens the vehicle does not let me shut it off. The engine isn’t running but I can’t power down the electronics system.

POWER TRAIN
Shortly after the warranty expired my torque converter went out and damaged the transmission. After speaking with several transmission shops this is a known problem with this vehicle! The torque converter and transmission are poorly made, and no matter if you get all of your services this will still happen to you! This should be a recall on this vehicle. Less than 4 years old and I am having to spend over $5,000 to replace a transmission. The vehicle just hit 100,000 miles. If this is a known issue with this vehicle why has it not been recalled? The dealership tried to tell me I just needed battery cables replaced. I decided to get a second and third opinion and as I suspected the transmission is gone. There were NO warning lights, the car just suddenly started not wanting to change gears while driving. At the red light it jumped and wouldn’t move which made the car behind me almost hit me. There were no other symptoms until the gears started not wanting to change. No noises, smells, or any indication that something was wrong. The vehicle is now at a transmission shop awaiting repair. This needs to be a recall if this is a known issue.

The vehicle is at the dealership for the second time to address this issue. Very very unsafe! they will work fine and then all of the sudden while it is raining they will stop working. Night time is the worst.

Tranny failed at 92k miles even though properly maintained. Since new tranny installed by dealer (out of pocket cost) had to return due to tranny slipping into neutral when driving highway speeds and taking foot off gas. Dealer performed TCM and ECM flash updates. Cost out of pocket for programming. Issue came back less than 2000 miles later

SERVICE BRAKES, POWER TRAIN
My 5 children and I experience a traumatic experience in afternoon traffic as my 2015 GMC Yukon failed to pick up speed while waiting to make a left turn at a traffic light. The vehicle - no matter how hard I pressed on the gas didn't accelerate immediately which almost cost an accident. The vehicle rode smoothly for a few minutes then out of nowhere - it started jerking and stuttering bad for 15 seconds or so then would go back to riding smooth. When pressing the brakes - it seems to "lock" to a certain extent, so I have to press really hard on the brake to slow down/stop the vehicle sometimes makes a strange noise when doing so. I took the vehicle to be accessed by a service center in my area - it was at that time that I was told that my vehicle issues are known common GMC issues in these vehicles & more unfortunately. It's unfair to be penalized with an expensive transmission repair when these issues are known to the manufacture but not the consumer - despite being "VIN specific" as told by GMC customer service. This vehicle is needed as it is utilized to transport my children however, it's unsafe at & parked in my driveway. I was directed to reach out to GMC for remedy of the identified issues.

On March 15, while driving on a busy road our vehicle STOPPED from catastrophic engine failure without warning which put my family and I instantly in danger and nearly got us killed. Due to the high traffic where it stopped we were scared to stay in the vehicle and also scared to exit it .. so we contacted the police before calling a tow truck. When the police arrived, they parked a car in front and behind us and put their flashers on to make us somewhat more safer... we had the vehicle towed to the local dealership and contacted the actual dealership where we purchased this brand new vehicle with zero miles that was about an hour away and they sent soneone to get the SUV . Once they ran a diagnostic they discovered metal shavings in the oil and said it needed a new engine! What's alarming is that after hearing this we started googling terms like "Denali engine failure" "Cadillac ecalade engine failure" and discovered a huge amount of consumer complaints from other GMC customers on forums with their brand new GMC vehicles with little to no mileage and ALL had the metal shavings in the oil and shockingly needed new engines! FYSA- All complaints are on the 6.2 engines specifically. This is a huge safety issue as these vehicles are stopping in the road without warning. If someone doesn't do something I'm afraid someone is going to get killed. Please look into this and help us. We paid over $100k for a vehicle we no longer can trust. We were not given a police report but I'm sure the information about this incident is available by FPD since they were called and remained on scene with us for nearly an hour waiting on the tow truck. The dealership was great by the way, we do not blame them as we feel they are victims too. This is a GMC problem who are knowingly building and selling unsafe SUVs with the 6.2 defective engine that's literally stopping without warning while driving.
