Check Engine Light On problems of the 2010 GMC Terrain

My Terrain recently got the check engine light on the mechanic is telling me that it is the timing chain that all of this vehicles have this problem and I got lucky it only jumped one tooth to repair will cost me around $ 1500 what I don't understand if this is been going on for long time how is it that this does not constitute a recall.

2010 GMC Terrain I bought off a dealership lot in March 2019 not knowing all the reported issues! being a single mother I thought I was buying a fairly priced,gas eff. Reliable car. From day 1 I have had countless oil changes, my tire pressure warning light will not turn off after replacing stems,tires nothing turns the light off! it lacks pick up speed and rough gear changes. While driving and coming to a stop it would hesitate and chug like it was going to die. I returned to dealership where I bought it from replaced the timing chain. Upon taking it home,2 days later check engine light came on. I returned to the dealership that replaced the chain they informed me I lost 2. 5qts of oil in those 2 days and that id need to replace or rebuild the engine! my warranty company (fidelity) whom I purchased powertrain warranty from is telling me it is normal ware and tare they will not pay a thing,after reading all these reports clearly it's not normal ware! I still owe $6,000 and I don't have $3500 to get my car back! I don't know what to do or who to call will someone please help? I thought GMC was a reputable maker, was I wrong?.

The contact owns a 2012 GMC Terrain. The contact stated while driving at low speeds, the vehicle stalled with the check engine warning light illuminated. The vehicle was towed to contact's residence. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 130,000.

I only had my car for just about one year. The check engine light ended up coming on and I found that the catalytic converter was the culprit. No matter what I do this sensor comes on. Now here recently, the light to check the airbag system has come on. I have once before checked to see if there were any recalls on this vehicle, but there supposedly were none, yet I see so many complaints about the same issues that I am having on top of the defrost system being no good. This car has cost me more than it is worth and selling it would just leave me with nothing because I still owe on it. I need fixes and answers before this thing ends up in flames which is what I fear each day I drive it. This began in August of last year and now I am getting scared for my life.

Just like so many others that have complained, the engine seized with just 85,000 miles on it. It was always well maintained and out of the blue, while driving on the highway at about 45mph (in light traffic), the check engine light came on and it died. I've had two mechanics look at it and both say it needs a new engine. They both also say that this is one of the worst engines that has ever been manufactured. I now have to decide if I want to pay $6000 for a new (used) motor, or if I want to walk away and eat the balance of my loan. Thanks GMC!.

The car check engine light won't go out and the onstar rep says it is transmission related to possible timing chain which was replaced aprox 2 years ago at that time there was no warning as the check engine light coming on I travel only highway most of the time and im in fear that the car will stop without notice I feel if the chain is the issue again they should make good on the car it has aprox 71000. Miles at this time and if it stops on highway could be cause for deaths to me or maybe someone else.

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.

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.

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.
