From the time I purchase this car I had to replace the sunroof motor, replace the shocks, replace the truck lock, replace the fuel tank, and I had some transmission work done. My biggest problem is having to replace the low beam lights every 6 months. I suspect there is an electrical problem, but cannot completely prove it with the manufacturer. With 1 year, I had to replace the bulbs 3 times. I had to replace the front low beam bulbs and the brake lights. …”

The vehicle was taken to an independent technician who replaced the bushings for the second time as well as the front control arms. …”
