I was experiencing problems driving my vehicle. It was riding rough and making a loud noise when I accelerated, so I took it to my mechanic and I got spark plugs and an oil change-still was riding rough. I went back and got a cam shaft position replaced-still nothing changed. I took it to another mechanic. He said it was an O2 censor. Changed it and nothing changed. No one could tell me what was wrong or what the noise was. Finally one morning on my way to work I had to pull over on the highway bc the car wouldn't accelerate. Got it towed to a different mechanic and that's when I found out it was the timing chain. After doing some research I was getting quotes for $2000-$2500. Finally one place told me to see if there was a recall. I called GMC. They said there is a recall on the timing chain. They connected me with a local GMC dealer who informed me after evaluating my vehicle that it's out of warranty and 5000 miles over the limit. Well I'm still paying for this vehicle and I owe $5000 on it. Clearly I was sold a lemon but what are my options now?.
