While driving on 95, I lost all engine and power breaks with no warning. A message came up on my dash stating that I had lost engine power. Fortunately an exit was up ahead so I was able to get there and coast down the ramp. I attempted to make a right turn to get out of the way but ran out of momentum. Dealership stated my vacuum break pump failed and went into the cam shaft. They had to replace those and the solenoid actuator and value. They also conducted an oil change. I received it back yesterday, started the car today and the check engine light was on. They found more debris and replaced another point and said if the light comes on again it's the timing chains in the engine. I went out leave and the check engine light was on. They are now keeping it to repair the timing chains. I am fighting with GM to cover the expenses since I see this is an issue in previous models/years of GMC and Chevy vehicles.

It began with showing "Service Brake Assist" for about 2 weeks + then on Dec 18th 2023 around 10:30 as my fiancé was stopped at a stoplight and all of sudden when the light turned green she attempted to continue forward as traffic started to move only to stall stalled out before any movement could be achieve the battery was reading severely depleted and the vehicle would not function at all she was stuck in Drive and could not put the vehicle in neutral or even park to even try to restart the vehicle, she could not even turn the steering wheel, roll down the windows, open the door, or anything. the only thing she was able to accomplish was opening the hood so an officer that had arrived at this time could give her a jump, The officer also proceeded to leave the negative cable on the battery terminal and disconnected the Positive cable from the battery terminal which would have indicated a bad starter or depleted battery when the positive cable had been removed, which was not the case. she continued to where her appointment was and that is where i met her and took over vehicle to transport it home, driving with hazards on. I arrived at the house with no incident. then at 4:45pm on the evening of 12/18/2023 while at the stoplight I had a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum where the vehicle wanted to stall out while i was stopped at a stoplight attempting to proceed forward. and then at around 10:20 pm while stopped at a stop sign a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum attempting to proceed forward. On Dec 19th 2023 around 10:00 am I test started the car by remote and it started up and then i turned it off, now it is showing that the battery is completely depleted at 1:26

Two incident warnings on my dashboard saying of my back hatch was open when it was not. Had it serviced because the dash warning would not shut off. Service said it was fixed then happened again. Twice this happened intermittently. Another incident when on navigation screen, when the Navigator gave directions it changed to phone screen and went back to navigation screen when she stopped talking, like she was calling me to verbally give me directions! the most worrisome was as I was going 50 mph on city street, my gas peddle stopped engaging with the engine and I was loosing speed, as I pressed on the gas peddle harder the car was decreasing in speed as I watched the speedometer. During that incident all was working including brakes, radio and steering. I proceeded to drift into a driveway to stop the car for help, good thing I was not on the freeway could have gotten killed. The car is getting serviced now, I do not want it back, will trade in for different make/model is this considered a lemon and which laws/action do I take? I've only had the car only 7 months when this started to happen.

I purchased my 2019 Terrain denali on 2/27/19. I began my drive into work this morning (3/4/19) and merged onto the freeway and seconds later heard a loud explosive sound, only to realize the first half of my panoramic moonroof was shattered (see inside photo). Shards of glass were falling into the vehicle but it had not collapsed completely at this point. I did not drive under anything that may have fallen, there were no objects in the road that came up to hit my vehicle, the glass just shattered out of nowhere. After calls with the dealership and roadside assistance, I decided to attempt to close the inside cover for the moonroof and drive to the dealership. I was able to do so successfully but as soon as I moved the vehicle, you could hear the glass collapse (see picture).

Lift gate on this vehicle opens to a height of 69 inches. At 74 inches I am constantly banging my head on the lift gate. My 2017 model opened to at least 76 inches which is more reasonable. I consider this a safety issue, as this is a flaw in the design of the vehicle. The model that has a power lift gate opens to around 76 inches.. a full 7 inches higher than the manual one.. the dealership never pointed out this problem to me seeing that I am 74 inches tall.
