Vehicle began to use excessive amount of oil and idel up and down and sometimes even shuts down. After about 3 months while driving on the interstate it began to shut down while in motion. I called for someone to check the vehicle out and he arrived called someone to check the vehicle and he actually told me it seems to be the motor gone bad but he asked would I drive it back home if he followed behind. It literally scared me and my 4 children to death when it shut down while in motion with that kind of speed so I don't trust putting my children in it now. I don't think its safe at all. The vehicle I once thought was perfect for my family is turning out to be a nightmare.

The contact owns a 2012 GMC Terrain. The contact stated that he was informed that there was no oil inside the vehicle upon taking the vehicle to an independent mechanic for the first oil change. No warning lights appeared on the instrument panel prior to the discovery. The manufacturer was notified of the failure and the contact was given a voucher to have the vehicle inspected. The contact was informed that the failure was due to defective piston rings that were too expensive to be replaced. As a result, the engine became inoperable. The vehicle was diagnosed with engine failure. Prior to the engine failure, the contact also stated that the vehicle revved and accelerated independently without warning, while driving at various speeds. The contact noted that prior to the engine failure, both windshield wipers were defective due to the windshield wiper transmission. Both windshield wipers were replaced on three separate occasions. The vehicle was not repaired. The failure mileage was approximately 55,000.

Me and my wife own a 2012 GMC Terrain 2.4L engine. Oil consumption is 1 quart every 500 miles the dealership located at 16400 w colfax ave golden co had are vehicle for two weeks running diagnostics tests and using a on board computer hooked up to the vehicle with no answer for why the vehicle was losing power and gas pedal going to the floor with no codes pulling up as they mimicked the problem with a on board computer hooked up to the vehicle while a GM tech test drove the Terrain this is a major problem for driving on the highway its like going 45 mph on the highway and slamming on you'R brakes then the vehicle kicks back into gear.my wife is a nurse and needs her vehicle to get to and from work especially with covid-19 if she cant make it to work people could die covid is nothing to play around with and nurses are not allowed to call in while covid is going on this problem with this Terrain needs to be investigated if a GM certified tech does not know what is going on with this vehicle who would.

Pistons are bad and dealership at 16400 w colfax ave, golden co 80401 refuses to replace and oil consumption is to much. This problem has been going on for to long I was told by management after I paid for a high pressure fuel pump replacement if the problem was still there it would be fixed at no charge to me. Since then the manager quit and there is all differant staff and I have tried the corporate office still not resolved the only thing left is small claims court with a cap at $7000.I do not want to go to court if I really do not have to but if necessary I already have the paperwork to file.the dealership had my vehicle for over two weeks running diagnostics with no answer I asked them to check the pressure coming from the oil cap when you remove it.nothing they just replaced the high pressure fuel pump and the problem is still there this vehicle is not safe to drive and can cause a wreck if not fixed. Loses power and gas pedal hits the floor I had to pay for a rental car the whole time the dealership had my vehicle because they said they would get us a loner vehicle and that never happened this will be my last attempt to resolve this matter out of court.

I was driving my sons to school at around 7:45 am, my vehicle cut-off in rush hour traffic. I had to quickly put on my hazards and flag the vehiclesin my lane and driving behind me to move ahead of me. I called GMC who told me to go the nearest dealership but my insurance said they would send me a tow truck to get me there. The car was towed to rockville center GMC which diagnosed the vehicle. They charged the battery and claimed a cable was loose but that didn't make any sense. Three years after the same thing happens again but this time the dashboard warning stated the engine needed checking. This time I took it back the neaborhood's autozone which ran diagnostic tests and suggested I return to my dealership with those diagnosis codes/issues. The dealership took notes from autozone's printout, completed a scan test and stated that a camshaft actuators needed replacing to prevent stalling while driving. Whe nasked why this wasn't done when I took there for that very same issue 3 years ago he said that wasn't the issue but now I have to pay for the repairs because I'm 1 wk short of the warranty expiring.

My daughter was driving a 2012 GMC Terrain when the timing chain broke and caused the car to lose power and lock up immediately. She was driving straight on a two-lane state highway. It was determined the damage ruined the motor and required a complete motor replacement. The mileage on the vehicle was 99,035 at the time of the incident. I wasn't aware until today that I could file a complaint with the National Highway Traffic Safety Administration. When I called the closest dealer (30 miles away), they were not very helpful.

- Liberty, KY, USA

Vehicle was obviously burning excessive oil. Took it to a GM dealership and was told it was a non issue. Now the vehicle is past the GM max mileage for their recall (they won't take responsibility)!and has developed a white white frothy residue on oil cap, dip stick. (piston rings and/or gasket failure). Will never buy a GM product again!

Burns oil, which GM will cover to fix but will not cover the issues that happens when oil is burnt and what it caused. Had to replace exhaust manifold, O2 sensor, catalytic converter and cam shaft senors; these I had to pay for out of pocket. Not sure exactly when it happened but was middle of 2019. Went to GMC about how to get resolved on an issue that they caused that I had to pay for, which first resulted in a 1 yr engine warranty which they pulled with out my knowledge, then after a complaint to the BBB the best they could offer was a $1000 coupon for a new car. GM should cover those other issues since its an issue they know and fixed.

- West Fargo, ND, USA

My PCV valve clogged and caused the rear main seal to blow out. This is a common known problem with this vehicle and GM has recalled certain vins with the same issue and the same engine. Now my car is at the dealership having $1200 worth of work done that could have been prevented with a $12 part. I just had my vehicle at a GM certified shop 7 months ago for warranty work and was not notified of this possible problem.

- Rogersville, MO, USA

Complete motor failure, engine oil loose, complete loose of control. While driving down the highway, this vehicle had a sudden oil loose, no warning lights came on causing my spouse to loose all control of the vehicle nearly incurring a head on collision on a local highway at speed of 60mph. We had to have to vehicle towed to a local shop and is no longer drivable and the motor is ruined. The vehicle only has 83,000 miles and all evidence of motor failure appears to be on the manufactures behalf, as the motor over pressurized and lost all oil and didn't have a safety warning, this could have killed my spouse or others. I have attached photos for review

While driving on highway the message came on losing oil pressure, shut engine off. By the time I was able to pull off the highway to the side the engine ceased up. Oil gasket blew off.
