Check Engine Light On Problems of GMC Terrain - part 2

My car is idling when it suddenly begins to idle roughly then stalls. There is a "reduced engine power" warning that appears with the check engine light, and "service stabilitrak" with the stabilitrak light. This has happened 3 times, twice when the vehicle was stationary, another time in motion, driving on a city street, and I was able to pull over before it died. In reading other complaints, this seems to be a known safety issue for 2010 GMC Terrains and should be investigated as a recall issue.

Check engine light has illuminated multiple times. A rough idle was initial indication something was wrong. I have had the vehicle tested multiple times and have been told from dealership and other mechanics that it is a timing issue. The vehicle will start and drive. Safely problem is while driving through a busy two way intersection, after coming to a complete stop, the vehicle would not accelerate as needed almost leading to an accident. Under normal working condition I would have had no problem making it through the intersection in a reasonable amount of time. It very slowly puttered through the intersection while I had the accelerator pushed to the floor board and after finally crossing the intersection began to accelerate at an unexpected speed. I began to accelerate so unexpectedly that I temporarily lost control of the vehicle and crossed into the incoming lane of traffic.

I was at a busy intersection with my 19 month old son at 5:00pm on Friday, March 27, 2015 when my car just died on me. After having it towed to a non GMC service station, they informed me that I had no oil in my car. I was taken back by this because it had not even been 1500 miles since my last oil change and I had no warning at all, my oil light or check engine light never came on in my car before it died. I have been more than up to date on every oil change since I have owned the car in September of 2013. Due to no oil in my car, there was extensive damage to the engine resulting in me having to replace the engine in my car. GMC informed me that this is not a recall and it should be!!! this is completely dangerous and GMC will not reimburse me for the engine that I have to put in my car even though this was not caused by me.

Driving back from a two hour trip at aprox 55 mph our 2010 GMC started flashing "reduced engine power" with the check engine light, and "service stabilitrak" with the stabilitrak light. Speed dropped down to about 30 mph without control. The car was idling heaving with rmps jumping. We pulled over to the side of the road and restarted the car, the only light that remained on was the check engine light. Speed control was restored. By the time we made it home, aprox 20 miles, the check engine light turned off. Then a couple weeks later again, twice in one night, back to back. I called the dealer for an appointment because I assumed it would be covered by a GMC warranty, they did not have availability for 7+ days. The night before my appointment it happened again but did not correct itself and we had to drive it to the dealership at 30 mph. I just received the news, $800 later, it needs a new throttle body, exhaust cam solenoid and another repair to the camshaft. I do not have the paperwork back from the dealer yet for additional details, but am disappointed that this is a common problem with the 2010 GMC Terrains and they take no responsibility for the repairs. This should be a recall. There is a lot of potential danger to having your speed drop with no warning or control.

Car die (stall) at idol after warmed up drive it 10 miles stop at stop sign it die restart die again may do that 3-4 times before it will take gas and run does this intermeditly run fine for half a day stop run in store come out restart and it die (no chugging just die) auto parts store said it was a crankshaft sensor when they checked what had the check engine light on (note check engine light not come on each time it stalls).

I was driving the vehicle on the highway and all of a sudden it slowed down to about 20 mph without any warning. I looked down and saw the traction control light and check engine light on. In the middle of the dashboard it said engine speed reduced. I backed down an entrance ramp to get onto a local road. After 1 hour the car was restarted and seemed ok. Not long after it happened again. I took it to the GMC dealer, they drove it 47 miles and could not get it to act up. I got the car back, drove it 70 miles home and the next morning it happened again, 3 miles from my house. I had it towed to the dealer. The dealer then replaced the throttle body assembly for $540. It has been fine for 2 weeks. In 2010, GMC decided not to cover this part under the engine warranty (as it did in previous years) and now assigns it to the emission system which is not covered. I have seen this problem listed all over the internet on many vehicles. It is a dangerous situation when the car slows down like this on the highway. Please add my complaint to the long list of people who have this problem. Thank you.

I have had two occurrences now - the first happened a couple of times between 15k and 20k miles, with the car stalling when setting a traffic light. I also got a check engine light. I took it to the local GMC dealer who said the check engine light went out but they didn't know why and were not able to find the source. Just this past weekend at around 25k miles, my fiance and I were setting at a traffic light and the car stalled out. After the cars behind me were laying on their horns, I got the car started again and was able to continue traveling. I scheduled an appointment again at the local dealer, but after reading similar issues from other owners, I am starting to doubt they will correct it.

Tl * the contact owns a 2012 GMC Terrain. The contact was driving 5 mph when the vehicle stalled and the check engine light illuminated. The vehicle was not taken to the dealer and the manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and the current mileage was 3,600.

My truck experienced it's first problem in August of 2011. I had only had my truck for six months. The truck was entering onto the expressway and as I was pressing the gas the truck begin to stall. The reduced engine light came on and the truck deaccelerated and cut off. We were blessed that we were able to get to right shoulder of the road. We waited about ten minutes, the truck finally started and the engine light remained on. I contacted the dealer and took the truck in as soon as I could get an appointment. Was told the truck was fixed and since I have been in five times for the same problem. The fact that the truck deaccelerates while driving on the expressway is enough that I don't want to drive the truck. I have been using other peoples cars and trucks because I don't want to put mine on the expressway out of own. It is a death trap waiting to happen and anyone driving a Terrain should be made aware of the problem. The service department did everything possible and had to contact manufacturer about the problem and they could not narrow down the problem. They have replaced so many parts at this point I have lost track of things that have been replaced. This truck is not safe and the problem is not been resolved. The car still idles and shakes and no one plans to find out why as long as the engine light is not on. No one wants to take responsiblity for this issue and it is really disappointing that the manufacturer would rather not deal with this problem and wait for a fatality to occur before looking into. You would think they would learn from Toyota and take customers lives seriously. Would they put there families in this truck ? I just want them to take the truck back because I don't want to use my life as an example for a defective truck.
