I bought my vehicle the later part of 2021 and the transmission and engine no longer work and need to be replaced. When I first purchased the vehicle the battery completely died in less than 6 months. Numerous repairs and now the warranty won't work since I am over 60000 miles even though I have not met the expiration date on my warranty. They want to charge me between 8000-12000 for repairs.

I'm in need of a repair on my 2021 Buick Encore GX. It was seen at GM of Marion on July 30 for a warning light that came on as I was driving down the road after having an oil change. It stated my power was reduced. I took it in, and they told me they had just diagnosed this problem for another Encore owner, and it took two weeks to get the part in. It is now September 22, and I still do not have this fixed. It is a safety concern and I have been calling GM about it almost weekly, trying to get some help. How is it safe for my daughter & I to be driving down the road with only half power? I cannot pass anyone - the speed isn't there. I can't just pull out or even merge onto the interstate for fear of being ran over. And GM does not appear to care. I've been told by multiple dealerships that GM has them. They just will not freely send them out to dealerships to repair cars. I think if they have a car sitting on their lot that has the part, they should be allowed to use it to take care of the one that is already sold. I'm at 31,000 miles, and they told me it may not be covered if I am outside of my warranty when they decide to send the part. I need some help!
