2017 GMC Terrain

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.

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.

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.

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.

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.

main seal blew is in dealership now. it was not running right as i drove it was afraid it would die in the middle of the road. just inspected at the dealership. i got the engine light about a mile from my home where it sat till it went to the dealership.was over 4 quarts low with oil but never had oil light or anything else before it showed engine light.

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.
