“I purchased a 2012 Gmc Sierra denali from stahl motors in monterey, ca in february of 2015. They are not willing to pay for the damages to my truck even though they sold me a completely dangerous vehicle, which I will explain. My truck didn't feel right as I was driving so I decided to take it to a shop to get looked at. There is a long list of things that is wrong with the vehicle, but I will mention just the main ones. The truck was sold to me without the rear brakes hooked up. The brake lines for the rear calipers were capped off by the rear differential. …”

“The fuel injection pump cp4 had a catastrophic failure as I was driving on a heavily traveled four lane highway, us rt.20. I lost power steering and brakes. I felt fortunate that I was not towing a 16,000 lb. Fifth wheel camper down a mountain road.I say this because it was extremely difficult to maintain control over the truck steering it and bringing it to a controlled stop. I have read about these pumps failing on numerous diesel ford and GM trucks. I also feel if a woman or small person had this happen to them the outcome could end in loss of control resulting in injuries even deaths. …”

As I pressed down on brake to stop, the vehicle continued as if the anti-lock brake system slipped, causing the truck to drive forward crashing through the sheetrock wall and finally stopping after hitting the glass windows. Two weeks later, after all cosmetic repairs were done, the vehicle did the same thing in another parking lot, but luckily broke before hitting the curb and light post. …”
