Cam shaft position actuator & cylinoid & balance shaft chain malfunctioning four times between 65,000 & 97,111. Two dealerships stated that they weren't aware that this was a recurring problem, even though all dealerships have access to the gm global site that lists all repairs and this new model had excessive powertrain repair issues due to the 2.4 liter engine. Gm customer care utilized stall tactics by insisting that an "oil consumption" test be done that caused wasted miles and time and stalled correction of the problem by pushing the statute of limitations past the 4 year limit because they knew the car should have been repaired with a new engine or new car. Neither dealership had the integrity to assist me as the consumer with this issue, in fact I had to seek assistance from external agencies to even learn that there was a complaint process higher than the dealership and customer care when there are repeated repairs for the same the issue.
2010 GMC Terrain engine complaints
Page 5 of 5: complaints 101 to 117 of 117, newest first, as owners wrote them.
It stalled and the check engine lights came on. This happened again 12/13 replaced exhaust cam solenoid and again in january 2014 when they had to replace the camshaft position exhaust actuator. The have also at different times had to replace the high pressure fuel pump, water pump and balance shaft chain, replaced the condenser, evac on the air conditioner on this vehicle and the other 2010 gmc terrain we own. We do not feel like we should have had to pay for the AC condenser since it happened on both vehicles we own within months of each other but we did. The other 2010 terrain we own was in the shop in january 2014 because it stalled and it was cam shaft and the throttle body about 2 weeks later we had to take this one in for the cam. The other terrain has we own has also had the cam worked on several times. This vehicle has also had several recalls for other issues. Something needs to be done about these vehicles because there are so many people having these same problems. Look on edmonds online forum at all the complaints about the 2010 terrains and the 2010 equinox. Something needs to be done so the owners can get rid of these vehicles before they stall again and somebody hits them and kills them like the six people who died because the 2007 gm cobalt stalled on them while driving. We need the federal safety agency to help us. They were also going to charge us on the other vehicle almost $900.00 to fix the cam shaft and throttle body, when the problem had obviously not been fixed one of the other times that gmc dealerships worked on it until I complained to gmc. Then the dealership said we had to pay about $250.00 because the owner has to pay something when its out of warranty. That vehicle had about 43,000 miles. I don't feel like the owners should have to pay one penny when there is a repeat problem on a vehicle and they can't seem to keep it fixed.
Tl- the contact owns a 2010 gmc terrain. The contact stated that while driving 40 MPH, the vehicle stalled and all of the warning lamps illuminated on the instrument panel. The vehicle was taken to dealer. The technician diagnosed that the throttle body and cam shaft were defective and needed to be replaced. The manufacturer was made aware of the failure. The vehicle was repaired. The failure mileage was 500 and the current mileage was 44,000. Pm
I purchased my 2010 gmc terrain in may 2013. After a few weeks of having the truck. I heard a rattling noise. I took it back to where I purchased it and they said I was out of oil. From may - oct. I have had to have 4 oil changes which my mileage was now 52,000. The service light never came on but could hear a rattling sound. They recently did a consumption test on the truck and they say everything looks fine. Now when I stop at a light or stop sign, my truck shakes as though it is going to turn off. It does this randomly. Of course they could not duplicate it when they test drove it. My light does not always illuminate and my speaker on the driver side will be static when I start up the truck. Needless to say , having the truck for only a few months and seeing this many issues is a huge concern, after reading all the complaints I am truly concerned this is not the truck that is going to last very long, even though I paid good money for it. Very disappointing. I have talked to many people who have had to have the engine replaced. Instead of going through all the repairs that seems like the ideal solution. Its odd when you read the other complaints, it seems even gmc doesn't know how to fix their own issues or don't know what is causing these problems. I read that gmc terrains have had 131 bulletins wow.
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.
On 10/17/2013 my wife experienced a sudden acceleration while pulling into a parking space at our local walgreen's pharmacy. As she was pulling into a parking space in front of the pharmacy the car kept moving forward slowly although she was pressing on the brake pedal as hard as she could. The car crawled up the concrete curb stop slowly and hit the steel pipe bollard placed in front of the curb stop to protect the walkway front of the store. No injuries occurred to my wife, no one was on the walkway at the time. Only damage was to the bollard (bent over) plastic bumper, grill and right front fender of the car. Bollard and a trash receptacle brought the car to a stop. This is the second time this occurred. The first occasion was about a year ago when I was driving on a neighborhood residential street approaching a stop sign. As the car was slowing down and I was pressing on the brake pedal the car kept moving forward with the brakes being fully applied. Could hear the engine straining at an increased RPM. I lifted my foot off the brake pedal and jammed it down hard again and the car came to a stop at the stop sign with the engine in normal idle. In the three years we have owned this car these are the only occasions the problem has occurred.
Experienced a complete shut down while driving; 1st accelerating to about 20 MPH, restarted vehicle, drove about 4 miles to my home doing approx. 35 miles MPH, vehicle shut down again. Have appt with wilkens-buick, glen burnie, md on 8/28/2013; hope I make it without someone crashing into me because of the shutdown. Just had 20000 routine maintenance work done. V6-2994 3.0l dohc.
Approximately around the high 4x,xxx miles the engine started giving me extended cranking issues. It would crank for 4-5 seconds and not start at all or start but idles really low like its going to die. I has done this countless amount of times, even caught it on video numerous times only because every time I bring it in for the starting issue I always get there is nothing wrong with your vehicle, have a nice day. It gets really frustrating when the wife and I daily drive it and it happens about 2-3 per week. At times when I turn off the car, it sounds like its still on for a few seconds and than turns off like when a building loses power. On another hand, over a month ago the dealership checked the oil and said I was really low on oil. But theirs still nothing wrong with my vehicle they claim. And to make things worse the seatbelt sensor came on and stays on a few hours after I picked up my vehicle from the last visit to get it checked for this cranking problem. This is the worse vehicle I ever owned. I would not recommend the terrain to anyone. Oh yeah, I also brought it too 2 different gmc/chevy dealers with no help from them at all. This is the last time I'll buy a gmc/chevy vehicle - built very poorly.
Camshaft position sensor error occurred. Gmc has issued a recall for model year 2011 terrains, but not 2010. Same issue is affecting that model year as well. (voluntary recall 11195 & 11195a).
Tl* the contact owns a 2010 gmc terrain. The contact stated that while driving approximately 50 MPH, the vehicle decelerated independently to 30 MPH. The failure occurred intermittently. The vehicle was taken to an authorized dealer eleven times in relation to the problem. The fuel injector and timing chain were both replaced twice. In addition, the engine consumed a large amount of oil within a short period of time. The technician recommended the engine be replaced. The vehicle was currently at the dealer for repair. The manufacturer was notified of the problem. The approximate failure mileage was 40,000.
Noticed a hissing noise. Thought was in cabin air filter, so we replaced (it was dirty). Hissing noise continued. Then hissing noise grew worse, no cold air from A/C. Brought to the dealer & the compressor was replaced due to a hole in compressor. 22675 miles, 2 yrs 2 mos in service.
Tl* the contact owns a 2010 gmc terrain slt. The contact was driving 25 MPH when the timing belt detached. The vehicle was towed to a dealer.

I own a 2010 gmc terrain 4 cyl. I have had several different service problems with my vehicle since june 2010. Although the service department at my dealership has been cooperative and understanding through all the service jobs performed on the vehicle, it has become disheartening and frustrating that my vehicle continues to give me problems with electrical, engine won't start up, static from radio, not able to play iphone through USB connection at times, random warning lights coming on and off on display console. I have been given several reasons of "could be" or "maybe" but never an actual concrete reason for all the numerous problems. The computer system apparently gives false readings on occasion to service department at the dealership about error codes and messages or no error messages will come up, even though there might be issues with the vehicle. My concern is with all the electronic issues, engine issue of not starting up, computer messages or lack of messages to the vehicle when there is an issue.. If I am driving the vehicle and don't know there is a problem because the computer system within the vehicle does not accurate report correct data about the status of the vehicle, then how do I know when to get the vehicle to get serviced before I am stranded with my children or worse yet, get into a car accident because of the vehicle's computer malfunction. My dealership in my hometown can only do so much with information provided by the manufacturer; so if they don't know what type of fixes to make, then my vehicle is not updated with necessary fixes when appropriate.
Tl*the contact owns a 2010 gmc terrain. The contact smelled fumes coming from the vehicle and noticed a hole in the exhaust manifold. The dealer made eight attempts to duplicate the failure. The manufacturer was aware of the failure. No repairs were performed. The current mileage was 24,000. The approximate failure mileage was 134. The VIN was unavailable. Updated 07/21/11 *bf the consumer also stated the air bag system was worked on seven times. Updated 10/11/11
The four cylinder engine consumes lube oil at an alarming rate. This could cause a catastrophic engine failure if engine oil level is not constantly monitored.
Tl*the contact owns a 2010 gmc terrain. While driving approximately 30 MPH the contact heard a clapping noise coming from the engine. The vehicle was taken to the dealer where the air conditioner compressor was replaced. The contact continued to hear the noise. The vehicle was taken to the dealer a second time where there were other repairs made. The contact was not sure of what repairs were made. The noise continued after the vehicle was repaired. The contact stated that the noise was constant when the vehicle was driven. The manufacturer was contacted and stated that the technicians could not diagnose the failure and offered no further assistance. The vehicle was not repaired. The approximate failure mileage was 15,000. Updated 02/11/11 *bf the check engine valve and catalytic converter assembly were replaced. Updated 04/21/11
Engine cutting out and dying while driving, horn honking at times, vehicle starts itself sometimes, blowing fuses. Vehicle tried to die on my wife while driving almost causing a serious accident. Dealer has not found a solution yet. They have replaced the bcm with no good results.
