Engine blew in vehicle due to excessive oil consumption from piston ring damage. Car had only 95K miles. Vehicle was being driven at 20 mph, bucked and turned off completely. We notified GM dealership at every oil change of excessive consumption. We put in a quart of oil every 1000 miles.a consumption test was never recommended. We then could not do one as the engine blew. Also damaged exhaust manifold, O2 sensors and cat converter. We have also replaced the manifold and sensors and have the cat converter repair this week. All told over 5000$ in damages that we have paid out of pocket. There was no recall for the piston rings. Some vehicles have since been issued a letter indicating that emissions issues due to excessive oil consumption would be repaired at no cost. Our car apparently did not meet that criteria. A lawsuit against GM has been litigated and won for the excessive consumption. We are part of the class action however have already been denied once for unknown reason. We resubmitted 3 months ago and have heard nothing. It is criminal that these vehicles have not been completely recalled.

I was driving about 2 months ago when the low oil pressure light went on on my dashboard and it said stop engine now with a very loud alarm. I pulled into a gas station to check the oil and I did have to add about 3 quarts of oil. So I assumed this would fix the issue but when I started driving about 1 minute after I started driving again the low oil pressure light and alarm came and it again said stop engine now. I finally got it home and I turned the car off and then tried to restart the car and it did not start. I had it looked at by a few mechanics and they said the engine was gone that it failed the compression test 3 time and the vavles were bent. I had just got a oil change about 1 month prior to this.

While driving to work on the freeway, engine began making a knocking/rattling sound; checked dipstick the next morning and there was no oil on it. Oil had just been changed 2,500 miles previously. Vehicle is consuming oil at an abnormally high, about one quart per 500 miles, and has no warning light to alert the driver when the oil level is too low. We are at risk of experiencing engine failure at any time while driving. We have discovered this to be a common issue after our other vehicle of the same year, make and model suffered catastrophic engine failure linked to low oil pressure. Vehicle has 93,400 miles and we have owned it since April 2020. This model year vehicle is known to be equipped with faulty piston ring assemblies which lead to excessive oil consumption. Additionally, there is no oil pressure sensor to alert the driver to the low oil; consequently, this misleads the owner into operating the vehicle with inadequate oil levels and causing engine damage. Complete engine failure can occur suddenly, creating an enormous safety hazard; we are lucky we were not driving at highway speeds or in heavy traffic at the time it occurred. GM issued a special coverage adjustment, but it was not nearly adequate to cover the extent of damage that can and does occur as a result of this defect, leaving many drivers stuck with unreliable, unsafe vehicles or astronomically expensive repairs.

While backing out of driveway, the engine stopped without warning and vehicle would not restart. After being towed for service, we learned there was almost no oil left, causing the timing chains to fail and the engine was damaged beyond repair. We had driven the vehicle less than 12 hours prior and there were no warning lights such as low oil, check engine, etc. The vehicle has just under 78,000 miles on it and should have been 1,200 miles and 2 months from needing an oil change.

GM used faulty piston rings resulting in excessive oil consumption. This resulted in blown engines. This vehicle also does not have a oil gauge or low oil light to warn the consumer of the know oil consumption issue. I was driving home and the engine started to ping as I got to the driveway. I turned off the engine, and it would not start again. I took it to GM and they said the engine was blown. See #16118-01: Special coverage-excessive engine oil consumption- (Jan 28,2020) GM was sued, but are denying most claims. See Terrain-equinox oil consumption recall group on facebook. The engine blew due to the oil leaking out of the pistons.

The oil in my car seems to disappear. I get my oil changed and after about 500 miles the oil is gone. There is no warning light. The menu says I had 50 percent life left on the oil. Check the oil and it is ike a rust color. Y engine had stopped. It will not crank. Now I have a car that's needs anew engine. I've looked online about this issue. Find out that people that have the same car has had the same problem. Something needs to B gone about this issue. I have no warrinity left on the car. It all has to B out of pocket.

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.
