About mid October while driving at 60 mph it shut down again almost causing a wreck went to 30 miles per hour again. Hurt my wife’s neck when it reduced speed so quickly. Took back to dealership and I told them this car is dangerous this was with about 20 k miles Been in shop was told it is scanning with 22 repair codes we have not had the car for 5 weeks and are trying to work with gm and dealer to get us out of it. But as of this report no progress. On interstate in city traffic this car will hurt or kill many people. I’m refusing to let my family or myself drive it. There is no warning when it will flash lights in dash and reduce speed. Also the front crash sensors went out and are currently not working we have all service records and paperwork that has been done including maintenance records We were given vehicle back with no warnings. I went to Nita’s and ran vin and it still shows issues. We are still making payments but driving a loaner car. The car is dangerous. I advised the dealer the first time it happened. I didn’t want it back. My wife went and got it and it sis it the second time and now she agrees it is dangerous contacted GM and they want to fix it but dealer implies they can’t ?..

ChatGPT said: There is a design flaw with the automatic light function. When you turn the knob to disable the automatic lights to avoid blinding someone while parked, the knob returns to the auto position as expected. This is a good system to ensure that the next time you start the car, the lights are in auto again. The issue is with the way the system indicates what is happening to the driver. When the lights are set to auto, the “auto” indicator on the knob is illuminated. If you turn the knob to running lights or full lights, the corresponding indicator lights up as expected. However, when you turn the lights off, the indicator light returns to “auto” even though the lights are actually off. While the physical knob should return to auto to make sure the system resets properly at the next startup, the indicator should switch to the “off” position so the driver knows the lights are off. I drove off in the city and assumed my lights were on because the knob said auto, but I later realized they were off. This creates a serious safety hazard. There is no way to know in that situation if your lights are actually on by looking at the knob unless you cycle the lights again. A recall should be issued to change the software or replace the button to make sure that this is clear to the driver.

On 15 Aug 2025, I was driving this vehicle on Rte 151 in raccoon township with my 2 children when the vehicle suddenly and unexpectedly experienced a “loss of propulsion” with a corresponding uncommanded shift to “neutral”. Attempts to shift the car back into drive were met with a “parameters not safe” caution. I was fortunate enough that the vehicle behind me was able to slow and an accident was avoided. The thought that this could have happened with my family on the highway, during adverse conditions, or any other scenario is frightening to say the least. Other owners of affected models weren’t as fortunate.

While driving on the interstate, I felt the engine "slip". Immediately afterwards, I heard a load knocking noise from under the hood, the check engine light came on, and the vehicle lost power. I was able to pull off the interstate. Called a towing company and got the vehicle towed to a GMC dealer. The dealership diagnosed the vehicle and noted a critical issue with the engine and transmission. Dealership recommends engine replacement. Vehicle is less than a year old with 15,400 miles on the odometer. This particular vehicle is not impacted by the GMC recall on their engine, however is has the same engine failure.
