The contact owns a 2023 GMC Terrain. The contact stated that while driving 70-71 MPH, the vehicle suddenly decelerated. There was a red flashing light illuminated.

No warnings of any kind went off; I wasn’t even going 2 m.p.h. and hit a piece of wood that was right on the edge of the grass next to the road at the park. This is dangerous, especially at a park or other places where smaller children are present if I get that close to something and the none of the sensors go off letting me know there is something/someone that my vehicle could strike if not careful. I have not had it looked at yet, but plan to. No warnings of any kind have went off and it was functioning properly prior to this. There is severe damage to my vehicle

When I bought the vehicle new from dealership, they told me that side blind zone alert was not available at that time due to a semiconductor shortage, but that it would be available and could be retrofitted after they were available. I noticed that the 2022 retrofit had been authorized, and I need to know when I will be able to get this option retrofitted on my vehicle. It has horrible blind spots, and I have to literally turn around completely to see if there is anyone in the blind spots which is very dangerous because I’m taking my eyes off the vehicles in front of me to see the blind spots. This is dangerous in city driving where you are going 70mph in 4-6 lane traffic, almost bumper to bumper. If someone hits the brakes while I’m checking blind spots, then that could cause a wreck. I have all the other driver assistance, so the front braking will brake, but it is not a good idea for that to happen when someone is riding on your rear when the brakes slam on. I know I’m unique because I only see out of one eye at a time, but I believe this would still be a terrible issue for anyone trying to drive in traffic. I know the assistance packages don’t replace human interaction, but I do rely on those options to help me because of my eye condition. I told that to the dealer when I purchased this vehicle and they assured me that it was just a result of the shortages and it would be available for retrograde. I have called the dealer three or four times to check on this because at first they told me I was on the list and they would call me when the chip came in and they said it would be a few months. Well it’s been over a year and when I call now, they say it isn’t available and I asked them if I could just purchase the system myself instead of waiting for the recall, and they said I probably couldn’t afford it or it be worth it. I have looked on your site and others and I’ve seen nothing about it being in the works, so I want to report it so maybe you will look into it.

I bought a 2023 GMC Terrian SLE brand new 14 months ago. It has 30,000 miles on it. I was driving down [XXX] and the car turned off. No warning signs! Not to mention The car had no power! I couldn’t even put on my emergency flashers! Me and my 3 year old son luckily were able to make it through a lane of traffic and up the embankment to call for help! I had the car towed to the dealership and they can’t find anything wrong with it! The car is acting normal now but I don’t feel safe in it!

The problem with this car that continues is that when driving over 65 miles per hour/ more or less, the driver side door rattles and shakes. It rattle and it looks like if the door wants to detach. It only happens on the driver side, not the passenger side. I put my arm on the arm rest, and my arm shakes and that is not ok. I am concern and want to know what can be done about it. I do not feel comfortable driving when this happens and its a new car, it should not have this problem. The problem started right after I purchased the car and I already took it to service it and they said it was the tires not having enough air, but that's not the case, cause it still doing it. I need to take it to service it again Please advise what can be done about it and if they can find what the problem can be. Your assistance is very much appreciated. Thank you.
