2020 GMC Terrain

I was driving on the highway below the speed limit when I heard a pop that sounded like a balloon and instantly the sound of wind getting into the car. I pulled over and found that the sunroof was rapidly shattering. I did not see a rock that had hit it. Maybe the tempered glass just exploded. I was not driving very close by any other vehicles at the time, but was on the highway.

My backup camera in my 2020 vehicle has failed twice. Once was covered under manufacturer's warranty, and it then failed again 14 months later, which is not covered under warranty. As explained by the dealer, a parts warranty is 12 months if covered under manufacturer warranty and 24 months if paid for by the owner. Different warranties for the same part? Additionally, there is a service bulletin out about this issue as MANY other owners are reporting the same issue. The camera parts are being damaged by "water intrusion". There is NO rust or damage that would be contributing to this, thus it appears to be a manufacturing defect. There is no way I should have had to replace this part twice with only 40,000 miles on the vehicle. (first time at 24,000 miles, second time at 38,500 miles). I feel that the manufacturer should be fixing these as they know it is a widespread problem.

Every time it rains, the floorboard of my car is soaking wet. I took it to the dealership, and they stated the leak is coming from inside the firewall. I have only had this vehicle for 2 years and just recently moved to a house without a garage. Now that I am just now noticing it, I am wondering if it was like this when I bought it, but I am only noticing it now that I do not have a garage. They want to charge me over $1,000 just to take apart the dashboard to find the leak and that is just insane. There is no telling how much mold, rust, etc. could be in my car from this leak.

While driving my vehicle, check engine light came on. Then, my car proceeded to flash about 4 warnings on the dash, Fuel Level Low (had half tank of gas), Engine Power Reduced, Service ESC, and Service Transmission. My vehicle shut itself off while driving 55 down a main highway and put itself into park. Forcing me to pull over and be stranded on the side of the road. In the way of other cars, with no way to get out of the way. I then had to shut car off, wait, and start it back it up. However, after the first time this happened, I cannot drive my vehicle more than 15 to 20 minutes without it doing this to me over and over again. To make matters worse, I am 37 weeks pregnant, and the last thing I need is to be without a car. I also had just gotten my vehicle inspected and an oil change the week before, with no issues to show. The only thing I did to my car before it did this, was remote start my vehicle, which I do every single morning and have for the little over a year I've owned this car. Also, my car has less than 60,000 miles on it!! The mechanic who is currently working on fixing this issue for me, has concluded it to be a throttle body, or the actuator of the car.

On 4/10/2023, I took my vehicle to a local GMC dealership because it was stalling and didn't have any power. Upon accelerating the vehicle it would stall and take off at a high speed. The dealership has had my vehicle periodically from April 2023 and it presently sets at the dealership because they ain't getting a code, But after the dealership drove the truck for over 200 miles, they were finally able to duplicate the stalling yet are not able to diagnose the problem!! This vehicle is very dangerous to be on the road and I have almost gotten hit twice and I'm not driving the vehicle anymore at this time. I have previously reached out to you all and I would be most thankful if you could get in touch with me. Thank you

I was driving approximately 75mph on the interstate. 3 hrs into my trip I started feeling hot so I turned the a/c up. In my peripheral vision I saw orange and thought a car was beside me on fire. Immediately I realized it was my vehicle. I immediately slowed and came to a stop. I put it in park and opened the door. By the time I started to exit there were flames higher than the rear windows. A car that was behind me stopped. They said about a mile back there was a spark under the car by the rear tire. Then it went up in flames.
