The contact owns a 2013 GMC Terrain. The contact stated while driving 45 MPH, the vehicle lost motive power and stalled with the check the engine warning light illuminated. The contact was able to restart the vehicle and pulled over in a parking lot, where the vehicle again lost motive power and would not restart. The vehicle was towed to the dealer, and the dealer stated that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 143,083.

Vehicle began to hesitate and then became disabled. A large amount of oil was evident under the vehicle and continued to leak. It was apparent that the rear seal had blown out. Vehicle was towed to a GMC dealership and confirmed problem. Another mechanic informed us of a recall on these engines but this has yet to be confirmed with the dealership after nearly 3 weeks of it being there.

The contact's mother owns a 2013 GMC Terrain. The contact stated while she was driving at approximately 30 MPH, the vehicle shuddered and stalled. The contact stated that the check engine warning light was illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the cam shaft sensor and timing chain needed to be replaced. Additionally, the dealer found that the oil level was very low level after having had an oil change the same day. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 129,000. The VIN was unavailable.

I have almost been in 3 accidents. My 2013 Terrain has stalled while driving..Cut off at lights. Engine reduced while driving and massive oil leak that gas caused timing chain and engine failure. I have read other complaints, and this is sad GMC has been allowed to get away with this. These engines are dangerous and need to be replaced before someone looses their life.

The contact owns a 2013 GMC Terrain. The contact stated that the vehicle was taken to be inspected however, the contact was informed that the vehicle could not be inspected due to the frame, rocker panel, rear bumper support, and the e-brake cable mounting bracket being extremely corroded. The contact was informed that the parts needed to be replaced before the inspection was completed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 91,276.

Vehicle stopped running due to timing chain issues at 106,000 miles. Dealer stated the 3.6L V6 is known to not last past 100k miles and they can't do anything. This needs to be a recall as it's a very prevalent problem.

I was driving my 2013 GMC Terrain to a friends house, I stopped at a stop light, when I picked up speed, the car stalled and wouldn't get up to speed. Eventually, it did pick up speed. I went to turn into her neighborhood and the same thing happened. Trying to get to the destination, I continued into the neighborhood. I stopped at a stop sign, and when I tried to accelerate, the car died. No indicator lights were engaged. I turned the car off and waited a minute or so and turned it back on. I got to her house, and charged my battery and drove home without issue. The next day, I went to have my battery checked and they alerted me to a horrible oil leak. I had the car towed to the dealership. The next day, the dealership told me that GMC would specifically have to look at the vehicle to diagnose. I had the car towed to my trusted mechanic and he told me the rear main oil seal blew out and found a service bulletin regarding this issue #14882. I made an appointment with the dealership only to find out that this isn't covered under the bulletin, because it expired in November of 2022, and it's not covered under my warranty. The warranty company stated, "if there isn't evidence of moisture in the PCV it would be covered, but since it's a known issue and a consistent problem with the vehicle, it's not covered." So, my only choice is to pay out of pocket for a defective part that will continue to break and cause the rear main oil seal to blow out of the car, potentially putting me and my 9 year old daughter at risk, because GMC isn't acknowledging this issue and recalling the faulty part that is the ROOT of the problem and has been widely reported. There is also a class action lawsuit that is currently open and ongoing (Case 2:22-cv-10785-MAG-JJCG) which is trying to hold GMC responsible for not recalling the part sooner - when they were made aware of it - putting thousands of consumers at risk. It's also fraudulent for this information to not be disclosed at point of sale.

Was driving vehicle all of a sudden reduce low power engine mode. Sign came on and something about stabilization traction. Not sure exactly what vehicle stalled out will not restart. Also have used too much oil constantly putting oil in one to 2 quarts every two weeks or more.

A loud popping noise was coming from the middle to back of vehicle. Upon inspection by independent repair shop a hole in side of transfer casing was found. No warning lamps came on to indicate any problem even after noise was heard. Once problem was determined it was felt that if vehicle had not been taken out of operation when it was and continued to be driven that a possibility could exist of the transfer case gearing becoming bound up and causing loss of control of vehicle due to various wheels possibly binding or maybe locking up. Transfer case has been replaced.The transfer case was disassembled and found to have intermediate shaft bearing (if I have identified it correctly) completely destroyed causing shaft to come out of alignment and all attached gears to mesh incorrectly causing gear damage. In reviewing this site it was noticed that this problem has occurred three to four times over the past few years to other vehicles as well. It would appear that there may be an issue with the bearing associated with the intermediate shaft on the side of the transfer case where the hole in the case is found and could possibly be associated with something in either the design of the transfer case or quality of the bearing itself.

While driving on the highway at speed limit 75mph, the vehicle (without warning ??) suddenly went into (Reduced Power Engine Mode/ Service Stabilitrack) jerked and slowed down to 35mp almost causing a pile up as cars behind and next to me where still driving above 70mph. If not for my quick reaction to turn on emergency lights cars behind me would have hit me. Immediately after I got off the highway I drove the car (at 35mph as fast as it went) to my nearest Pepboys. Here the vehicle was serviced for nearly a month until the problem was fixed. The cost was almost $6500 GMC has failed to notify customers if this potential issue which not only risks the lives of the drivers and passengers of the 2013 Terrain but those driving alongside it. This is not a new issue as I found the testimonies of many other GMC owners tell a similar dangerous experience. Please help! I have detailed invoices of the repairs.
