ENGINE
The 2.4-liter engine contains a defect that causes them to improperly burn off and consume abnormally high amounts of oil. The vehicle is available for inspection upon request. Excessive oil consumption cannot be reasonably anticipated or predicted and causes the engine to run while low on engine oil, putting me and other drivers at risk due to engine fire, unexpected engine failure, vehicle jerking, power loss, etc. Yes, both certified dealers, independent service centers, and myself have observed and noted the low levels of engine oil as soon as 500 miles after an oil change. I have spoken with GM representatives via phone about the issue, but they are not interested in inspecting the vehicle or offering driver support. They have consistently denied awareness of an issue despite hundreds of documented complaints and a pending class action lawsuit in the state of Missouri. There are no warnings, messages, or symptoms prior to discovering low engine oil levels. This issue requires drivers to self-monitor the issue every 500-1000 miles and requires an excessive number of oil changes to keep the vehicle at a safe level of engine oil for operation.

ENGINE
Car stalls out suddenly after stopping. The engine oil was changed as required and there were no warning lights on the dash. Took the car to a mechanic and the mechanic said there was no oil and metal shavings in the engine, and that the engine would need to be replaced for $10,000. The car is out of its warranty and slightly over 100,000 miles.

ENGINE
2.4L Ecotec engines contain a defect that consumes excessive engine oil leading to: unanticipated engine shutdowns, engine stalls, engine knocking, unexpected loss of power, and vehicle jerking. The first instance I was still in a parking lot, the second on was on a local street traveling at 25 mph. During the third instance, My son and I have driven our car on 4 separate occasions and while driving on the freeway at 70 mph just after rush yesterday when the engine shut off. I took the car to my mechanic who informed me that my vehicle that has less than 88k miles is burning up the oil and soon will need the engine replaced.

ENGINE
My car was driving without issue until I stopped at a street light. My car started rocking front to back while sitting at the light and every other time I had to make a stop. The engine light came on. I had the vehicle towed to an auto shop where they confirmed that the timing chain broke. Due to this my engine was damaged to no repair. I would need to replace it. My gmc terrain is a 2017 with only 99,000 miles. I further learned that GM is aware of this issue but failed to recall this issue or warn owners that we were at risk. This can cause a vehicle to stop in the middle of driving which could cause a death if in the wrong place.

FUEL/PROPULSION SYSTEM
Rear main oil seal is faulty. It caused the vehicle to leak oil to the point where it was dry. This is a known issue with these vehicles and could have caused catastrophic damage to the engine. Additionally, this can cause the vehicle to stop running and/or catch fire.

In September of 2022 my gmc automatically shut off right in the middle of traffic on a Friday night. No warring, no lights to indicate that something was wrong with my vehicle. I took it to a mechanic shop and they said nothing was wrong and they did a diagnostic test on the car and no codes popped up. A week later my engine light came on. And my car died again. Thankfully, I had an extended warranty on my car and took to another mechanic shop. It turns out the timing changes on my car needed to be replaced. Fast forward to today Jan 22,2024. I smelled burning oil every time I would drive the vehicle. The rear main seal and PCV was leaking in between my engine and transmission. I lost 5 quarts of oil between Wednesday and Sunday. My oil light never came in. Thankfully, my engine didn’t lock up. It is currently in the shop getting repaired. My car is still under an extended warranty.

AIR BAGS, ENGINE
The air bags will show that they are shut off while we are driving down the road with my wife sitting in the seat and they will also does it if we are just sitting in the drive way. Also they had a recall in the older models of this car for the pvc valve getting clogged and building pressure and causing the lower seal to bust and that happed to my car but they never gave a low oil light when it happed. All that happed was my wife was driving and the lower engine power came on while she was driving in traffic causing her to freak out and feel unsafe with my kids in the car as well. I contacted them about and they said there is no recall for the car at all about it. They clearly still had the same issues in my car because the pvc valve was clogged and then now I’m loosing all of the oil from my motor. When I went to out oil in it after work I had to add 4.5 quarts of oil to it and it only holds 5 quarts. It still never had a low oil light when I went to start it to get it to level ground so I could check it. Clearly this is a safety issue and I don’t want it to happen to someone while they are on the Interstate during heavy traffic and potentially cause an accident.

I was driving our 2017 GMC Terrain in subzero temperatures when my vehicle started making sounds and loosing power. With in seconds I heard a pop, and then my dash went crazy with alarms. I had it towed to my local mechanic who determined that the vehicle's engine was seized do to a frozen PCV valve that caused the engines real seal to give away. If need be, the the vehicle is currently available to be examined. My family's safety was in danger because of the location and frigid temperatures that were present at the time of the breakage. The vehicle has not been examine by a GMC dealer, just an independent mechanic. There was no warning what so ever of a possible problem. The vehicle started making sounds and loosing power. With in seconds, I heard a pop and all the lights on the dash light up. We had no other issues with this vehicle leading up to the breakage.

ENGINE, SERVICE BRAKES, STEERING
On Friday, January 19, 2024, I was driving home from school at night in my 2017 GMC Terrain when suddenly my car was chugging and quit. my steering and brakes froze. Other cars were passing me and it was snowing. I was scared someone was going to hit me. I was able to start it up again and to get it to a Walmart parking lot just down the road, but before, it would chug and quit again. My steering was hard. There was no warning light or service light on dashboard telling me something was wrong. I called my sister to come get me. The car would start, but would keep quitting. I called a tow truck and had it towed to the condo. The next day, I went out to start it and it would start and oil light came on. It smelled. I turned it off. I called another tow truck and had it towed to a Mechanic at a shop. He informed me on Monday that the engine was no good due to lack of oil. Even though he said there was 15% left on the gauge. He said these cars have had problems of using excessive oil and he has had to replace and fix them. He also said others had same issue and no warning light as well. I have to replace my engine. He said the cost would be between $5000-$6000. I can't afford that going to school. I'm afraid that if someone else has this problem they could get hurt. I am going to contact General Motors about this, but I'm sure they won't help. Any Suggestions?

ENGINE, UNKNOWN OR OTHER
In certain makes of General Motor vehicles there is a defect with the PCV system in which the system can freeze in cold temperatures which in turns causes excessive crankcase pressure in the engine, and can lead to a dangerous loss of motor power due to this defect. The dangers of this defect can be catastrophic to myself and others on the roadway as the loss of motor power can happen suddenly and can happen while the vehicle is being driven. General Motors has released many service bulletins regarding this specific defect. The most recent service bulletin that was issued was GM January 2019 Bulletin PIP5093C, so they are aware of this dangerous problem in these vehicles. For my vehicle I have had a certified GMC dealership diagnosis the problem, and submit their findings to General Motors. There were not any warning lamps, messages, lights, or symptoms signaling that there was a problem prior to the occurrence on January 15th, 2024.

I just had an oil change in late December of 2023. As I was driving to work on [XXX]. My engine locked up. There were no warning lights. By the time I was able to pull over, a rod had gone thru the engine. Apparently there was an oil leak but no warning lights. This has not only caused me to have to purchase a new engine but could have resulted in a collision while driving. After doing some research this is a known defect by GM and a class action lawsuit. GM has failed to recall these vehicles for a known defect. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this Vehicle in February of 2023, I had a problem shortly after with the oil always being low. I was adding oil to it all the time. 7 months later the engine blew. This is a very faulty problem with this engine that I am NOW finding out. This problem needs to be addressed and fixed. Now I am stuck with a vehicle that I still owe money on that will cost me 6 to 9 thousand to replace the engine.
