2023 GMC Terrain

I have had 2 different instances where my vehicle stops in the middle of a busy intersection or traffic and have no warning what so ever. Vehicle just shuts off and I am not able to turn back on to move out of the way. First time I got it repaired it was related to the fuel pump and now I am waiting to hear back from my mechanic to see what the issue is but so far it is an indication of the fuel pump as well. Both times I required help from law enforcement because vehicle shut off in the middle of the road and safety to myself and other drivers was an issue until tow truck arrived to move my vehicle.

Vehicle stalled while driving and would not restart. Strong gasoline smell present and on ground. Third occurrence. Vehicle stalled while driving at on busy road (safety issue both times). Strong raw gas smell. Would not crank afterward. Dash powered normally with check engine light. Happened previously around 27k miles in September 2025. Occurred again May 9, 2026. Occurred again today l, May 18, 2026. Vehicles is being towed to dealership again for the 3rd time

Took dealer 3/26 for Sam issue Engine Power reduced after already cause me hit curb. Got it out 4/1/26 Now 4/5/26 it happened again same codes after they claimed they fixed it. Also keep having Emergency services come on a caused my dashboard out. My issues is car keeps stalling losing power. Same codes as week ago after dealer fix. Also 4 time took for noises in my car from passenger side. They keep telling me they can’t replicate it, but you can clearly see where the door is not lined up. This has been going on for over 30,000 miles for that. Like some of these issues have been going on since the 36,000 but now I’m having issues where I’m losing power like this is insane all before 60,000 miles which I’m about to hit. It’s gonna end up getting me killed on the interstate. My vin also says it’s fwd it’s awd AT4 . Called dealer said only to update software clearly not the issue. My doors are off and they have refused to fix those for over 30,000 miles now. It won’t let me attach any pics for some reason I’ve tried since yesterday

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.
