The contact owns a 2016 GMC Terrain. The contact stated that while driving 40 mph, there was and abnormal clicking sound coming from the engine. The vehicle was later towed from his residence to an independent mechanic, where the vehicle was diagnosed with a blocked PCV valve which caused the rear main seal failure. The mechanic informed the contact that the clicking sound was from the oil draining at a rapid speed and that the engine needed to be replaced. The contact then called mauer Chevrolet (1055 50th St E, inver grove heights, mn 55077) and was informed of an upcharge for the engine replacement. The contact also called the manufacturer, and was informed that the vehicle needed to be diagnosed by an authorized GMC dealer. The vehicle was not repaired.

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.

I was driving to work this day then all of a sudden I heard a noise. Something like a fan. I thought it was the wind so I let the window down and listened because their were no lights on my dashboard. Then all of a sudden every light came on and it said reducing speed. I continued down the road...came to a red light and wasn't able to move after that. I had to get the vehicle towed to my home. I was in maywood and had to go all the way back to lynwood. Not before waiting 87 mins before the tow truck came in 6 degree weather. I had to go to the police station because it was too cold for me to be in the vehicle. I then got it towed to the repair shop the following day and was told it was my engine...again. The rear main seal had blown.

I was on my way home from work driving on the expressway, then all of a sudden every light on my dashboard came on...then my vehicle said reducing speed. I was able to get on the shoulder before it turned off completely. I had to wait for a tow truck for 2 hours. It was cold. I had to tow it to my house because the place that I previously went to was closed and I couldn't leave the vehicle there. So, it was towed to the shop the next day and I was told that I needed a new engine. Engine failure due to lack of oil from blown rear main seal. Seal blown out due to PCV.

I tried to start my car and it wouldn't start. This happened on a Sunday so I had to go to a place that was open. I had my car towed there and come to find out it was the solenoid. I had to get that replaced and also a fuel pump. This was the first problem.

On January 17,2020. I was drive with my son going about 35miles when all of a sudden my stalled out or felt like it did but continue to drive. The check engine light turned on and the dashboard screen stated engine power was reduced and my stability needed to be serviced. Or something like that because it wasn't on to long. Luckily wasn't going to fast and there were no cars behind me. I've researched other complaints and I'm not the only one. This needs to be addressed because if that would to happen on a busy highway. O.M.G.

I have been driving my vehicle when on three seperate occasions the service stabilitrak message flashed on the dic and I lost engine power. One of the times this happened I was on a road where the speed limit was 55 and the issue almost caused a vehicle to crash into me. The message goes away after about 5 minutes. I tried taking it to the dealership twice and was told they cant replicate the problem so now I dont even bother trying to have them fix it. How can a major safety issue like this not be fixed by GM!!

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.
