| Electronic Stability Control problems |
The electric power steering assist may fail momentarily and then suddenly function again. This can cause difficulty steering the vehicle, especially at low speeds, increasing risk of a crash. Although there is a recall which describes exactly what is happening recall 18v586000 the dealer says there is no recall for my vehicle at low speeds when I back up or turn I lose power momentarily then it comes back.
Engine shuts off, steering assist disappears and steering wheel is jerked out of my hand, stabilitrak warnings on dash, hvac screen goes blank, chimes start going off. This occurred as I was pulling into a parking lot and I almost hit another car. The vehicle was moving at no more than 10mph.
This is the second complaint that I have made to NHTSA. The first time, the vehicle was spontaneously turning off and shutting down during backing in and turns causing a safety issue. This resulted in a recall, and a "software update" that was done twice to correct the issue. Right and back passenger lights began to blink on and off and water gets into the brake light. The dealer told me this was m issue. This time the 4wd service light came and the car appeared to be stuck in "4wd low" making it "drag" at a reduced speed when driving. Also, the "service trailer brake" light came on repeatedly. I have never used the trailer brake. I took it into an authorized dealer, sellers GMC in farmington hills, mi. They told me I needed a new "module", so I paid to have that done. Within one day the same service lights came on again. "service 4 wd" and "service trailer brake. " I immediately took the vehicle back and am now being told it needs another software update and a new trailer brake transfer switch. Quite frankly, I believe that this model has significant, unaddressed computer software issues and the dealer does not know who to fix it. The car is unsafe because it spontaneously stops working appropriately during driving. The concerns have been various and always seem to affect steering, when turning or backing in. I am being charged for various control panels and modules. I am requesting that this concern gets addressed before there is a serious injury. I would like my vehicle fixed and returned to a safe condition. I was never told upon purchase, that this model would require so many "software" updates to remain safe. This should not be a burden placed on a consumer for a vehicle to operate safely. This is dangerous.
I have had an on-going issue with the steering, electrical and power steering and stability control. I have had repeated issues with the stability control turning off, sudden drop in electrical power, the steering wheel gets violently yanked out of your hands and sometime the car completely cuts off. Fortunately most have been at slow speeds or else the car would have flipped. It is the exact same issue other models have been recalled for but my VIN is not included in that recall. I am afraid of this issue killing me or my loved ones should it happen at speed or leave us stuck in front of on coming traffic. According to my dealer this is an issue the manufacture has know about for a while.
While in motion my vehicle shuts completely off. This is in the middle of traffic at times. It displays warnings that stabilitrack has been disabled and shuits down everything electrical. At some points it doesnt shut completely down, but instead hesitates and then picks back up. This happens in various situations whether it be on the highway, turning, or driving city roads.
Component affected: stabilitrac module cause: a power short in the electrical wiring harness inside the steering wheel column caused the stabilitrac (stability control) module to malfunction. Unsafe condition: the steering wheel would turn a full 180 degrees on its own at idle/low speed. At higher speeds, the car would pull to the left or right. The "service stabilitrac" light would activate on the dash and message displayed "stabilitrac disabled". Remedy: the steering wheel wiring harness was repaired and the stabilitrac module was replaced by my GMC dealership in the summer of 2017, the issue has not occurred since.
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.
