My check engine light would come on, the oil dipstick would be dry and multiple misfire codes happened. This went on multiple times because of oil consumption. I would pull over and call AAA to tow my car. Driving while the oil is low is damaging parts in my car, causing loss of power and can cause a fire. I have to check my oil dipstick every week to make sure it has enough oil before I drive. I'm adding oil multiple times before an oil change is needed. The oil consumption was confirmed by a GMC dealer and documented. GMC dealer inspected my car. The oil consumption started 08/10/21 and was documented again on 11/19/21 with GMC Tech stating what's wrong. Oil consumption is going on with multiple GMC vehicles and GMC has not done a recall and they absolutely should have a recall.

They’re a class action law suit going on now, about the pcv orifice on my car. This is what happened with my car the pcv orifice clogged and frozen then causing my rear main seal to break and loose oil. No oil lights come on when the car is low on oil. Also even if you fix the pcv orifice it could still happen again.. which means it could leave me and my young daughter stranded on the side of a road hi way or interstate and I’m not comfortable with this and the car dealership needs to get a permanent fix so this doesn’t happen repeatedly… I don’t even feel comfortable driving the car anywhere I’m afraid I will be left on the side of the road.

Leased a 2002 GMC Terrain/Denali on 12/30/2022. 34 miles on car. Loved driving it. I have put on additional 210 miles. On 01/20/2023 after dropping a 'CT' disc at my Oncologist I got back in car and was driving home. Still love my car. In doctor's parking lot the 'Parking' light would not go out when put in reverse. Same issue two times until I went into drive and car moved a bit. Then reverse, all ok. At stop light just beyond MD office I turned left. Initially I crossed intersection (yellow engine light went on) and gave gas pedal a push to go 45 MPH (legal speed on a 2 lane West bound). Two lanes on opposite side head East. All of the sudden foot still on gas speed drops to 25 MPH but Tachometer now reads 4000! Scared looking rear view mirror and 3-4 cars behind close to my bumper now and before slowing down hit their bakes. I being panicked took foot of gas and tried to go slowly forward again to get out of way. Same issue with 25 MPH only and now tachometer reading between 3500-4000. Really panicked as those 45 MPH (or more) cars slammed on their brakes. Were not so nice, but of course! Now went to side of road and stopped. Waited a couple of minutes started again but went no more than 25 MPH with a burning smell. Got to a parking lot and hit 'SOS'. 2 sets of 2 hours each no tow arrived. Talked to 'SOS' a number of times. Finally called wife she behind me with flashers and me with flashers drove home. No more than 20-25 MPH. Tow arrived and driver could not get car in reverse so pushed into street in our complex. Finally pushed enough to use winch to get car aboard. Took to dealer in FT Lauderdale (Sheehan) been there one week today and thy called at 5:00PM car finished. Admits transmission problem. Me what could I do? Dealer says to pick car up. One week for repair of this brand new car? My wife is petrified as to what happened. Doesn't want to take a chance to ride in it. Scary ride that day for certain. This all seems so one sided to me. That hurts.

Car died out of nowhere. Towed to dealership. Upon inspection we were told that the engine needs to be replaced. Had a 3rd party come to investigate and gave a diagnostic report. GM has notices and there are articles outlining the defect/failure of the engine due to excessive oil consumption and issues with PCV and rear main seal.

I bought this vehicle and NHTSA made GM release an extended warranty on this vehicle for excessive loss of engine oil. In 2019 I had to take this vehicle and pay several thousand dollars for the pistons to be replaced in my engine because I was 1 year past the extended warranty. Now 3 years after spending thousands of dollars through a certified GM store I am having the same problem excessive loss of engine oil. I have zero leaks and I have to put oil in my engine every other day. If I do not by the end of the week I will have an empty engine.

2015 GMC Terrain-The PCV system or rear engine seal froze and burst. It happened last month when GA experience record cold weather. When the vehicle’s PCV system freezes it caused pressure to build up in the vehicle’s crankcase that breaks or pops out the rear main engine seal and caused all of the oil to drain from the vehicle while driving. The engine has completely seized and will need to be replaced. There are several bulletins issues about this but no recall. After researching I see there has been a few class action suits filed within the past 12 months. This apparently has happened to quite a few people. I am now up to over 9K total. The PCV repair was 2800, then the timing chains 1800, only to find out that the engine suffered as well. New engine 4500. Please do something about this.

On Christmas Eve, I was driving home from the Northpark Mall in Joplin, MO during a record winter storm passing through my area. I was 2 miles from my house when the car went into what I can describe as a "fail-safe" mode and I was able to make it home safely. When the weather cleared up and I felt comfortable going outside again, I checked the oil and nothing was in there. It had leaked the rest of the way home. When I was doing a full inspection, I noticed the PVC Evac system valve was full of water from being frozen. When I called the dealership I originally bought my car from, he laughed and said he had the exact complaint come through for another GMC vehicle. I've looked online for options to fix it, but the solutions I found are costly and time-consuming. I live in an eight-person household and would like to be able to drive my own vehicle again. Thank you.

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.
