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!
