I was leaving the area of Hiram and my car started running different and you could hear a taping noise. I drove it to the GMC dealer down the street and they said it was the timing chain. I recently had an oil change and I was wondering if that could be the problem. The dealer gave me no recommendations or indications that I needed to change belts or components and my service engine light has never came on.

2016 GMC Terrain SLT, service engine light came on, vehicle stalled many times, restarted but drove and misfired, stalled again, was able to get it to repair garage who I trust. He checked code and said I had to put a complete timing chain kit. Total cost came to $992.36 and didn't have a vehicle for a week due to weekend and a holiday. The vehicle only had 30,763 miles on it at the time but was out of factory warrantee. Reading other customer complaints, this looks like an ongoing problem and I feel should warrant a recall. Additional info such as repair invoice is attached. Please reply when received and thank you for your time.

Less than 62,000 miles and the transmission has gone out. After searching to order the parts, I noticed several complaints come up across numerous websites where owners state that their vehicles transmission has died around 60,000 miles. This tells me GMC is at least aware of this issue and should enact a recall for this problem. The parts should be covered by GMC.

When driving the car will not respond correctly to the accelerator, delayed response. The car will also not shift correctly (as thought you are shifting manually). While driving the vehicle's gauges will jump up and down followed by the check engine lights coming on. Car will then go into reduced power mode. When pressing on the accelerator the engine will rev and then the car slams down into 2nd gear. The car has been in a GMC certified garage 7 times and out of service while in the garage 40 days and counting. Numerous attempts at repair have obviously been unsuccessful. GM is refusing to by the car back because I bought it at premier Chevrolet GMC in morgantown, wv used with 27,768 miles on 2/5/17.

2016 GMC Terrain will show the check engine, traction control and service stabilitrak lights after gauges jump up and down. Vehicle will then go into neutral and then suddenly slam into 2nd gear. This occurs at high rates of speed on the interstate, as well as, normal roads. The vehicle will then stay in 2nd gear and will not go into another gear when it is placed in manual either. Sometimes, after restarting several times, it will drive normally. Other times, it will not start once it is turned off. I have had it to the garage five times in the last month. The starter wire and starter relay have been replaced, loose ground wire tightened, and the ECM replaced yet the car continues to repeat the same cycle. Car currently has 53,300 miles on it.
