“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.”
