39 Engine And Engine Cooling problem

Failure Date: 08/29/2023

2017 GMC Terrain motors consume oil at an excessive rate (1 quart per 1,000 miles). Getting an oil change every 5,000 miles, even consistently, puts the engine at risk for major internal failure and safety risks to the passengers. My engine in my 2017 GMC Terrain has a broken timing chain and internal damage due to the excessive oil consumption issue. The engine will have to be replaced. Gm has known about this issue for years. Gm is in several lawsuits for this issue, but gm has failed to recall the parts of the motor that are excessively consuming oil. They refuse to help cover repair costs even though the costs are due to their poorly designed motor.

40 Engine And Engine Cooling problem

Failure Date: 08/08/2023

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.

42 Engine And Engine Cooling problem

Failure Date: 05/06/2023

In 10 degree weather after warming the car up and driving 15 miles began noticing exhaust smell but wasn't sure it was my car. No warning lights. Arrived at destination parking lot and car began to run rough and stall out and only then did engine light and oil pressure light come on. Strong exhaust/gas smell. Stranded in frigid weather with passenger in a wheelchair.

47 Engine And Engine Cooling problem

Failure Date: 12/31/2022

Pulling into work parking lot on Saturday 31dec2022, my engine died, thinking it was the alternator or the starter, had it towed to a repair shop. Didn’t find out until Monday, 2jan2023, that the engine completely locked up. The rear seal blew out and drained all the oil. I have been reading up on this and apparently this is reoccurring thing in said make and model of 2017. GMC and gm have to put out a recall on these vehicles with this manufacturing error/problem. Now I have to get a new goddamn vehicle because I cannot afford to get the engine replaced, which costs around $7000. End of message.

48 Engine And Engine Cooling problem

Failure Date: 12/30/2022

The rear main seal is out, which is causing an oil leak. The intake manifold failed because the pvc system has a clog which has caused too much pressure to build up and caused the rear main seal to blow out. (pvc pipe is freezing over in cold temperatures which causes the failure of the main seal to blow out subsequently leading to additional major issues and parts failure. This issue has occurred in an overwhelming amount of vehicles. ).

49 Engine And Engine Cooling problem

Failure Date: 12/27/2022

In very cold weather the 2. 4 engines will blow the rear main seal out and cause rapid oil loss causing engine failure. This is the second time it has happened. First time was February 2022 and the dealer said they havent seen this problem before.

50 Engine And Engine Cooling problem

Failure Date: 12/25/2022

Engine seizing at highway speeds cause oil to blow out the rear main seal….

51 Engine And Engine Cooling problem

Failure Date: 12/24/2022

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.

52 Engine And Engine Cooling problem

Failure Date: 12/22/2022

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.

53 Engine And Engine Cooling problem

Failure Date: 12/19/2022

Timing chain issues resulting in a loss of power of the vehicle while driving. The vehicle stalls out and shuts off. Or it will go into power saving mode and slow down to only 20mph. It did this to me one a major highway and I almost was in an accident. Way to many issues with GMC owners and the timing chain on their vehicles.

54 Engine And Engine Cooling problem

Failure Date: 02/06/2022

The rear main seal broke, thus causing major oil leak. I have been doing my investigations and there are many out there like myself. This is not an easy fix and is very expensive! I suggest if anyone else has the same issue please report it.

55 Engine And Engine Cooling problem

Failure Date: 02/04/2022

Available for inspection upon request. The rear main seal is out, which is causing an oil leak. The intake manifold failed because the pcv system has a clog which has caused too much pressure to build up and caused the rear main seal to blow out. There were no dash lights. My car was completely out of oil from the issue and I had no indicators. This issue has been check and confirmed by a GMC mechanic.

56 Engine And Engine Cooling problem

Failure Date: 01/30/2022

Driving home from work and was about 4 miles away from home when the "service stabilitrak' and "reduced engine power" lights came on. Safely drove home, parked vehicle on road to shovel driveway (snow storm). When I went to start it to move it into driveway "oil pressure" light came on. After moving it off street noticed oil on road where vehicle was sitting. Had towed to dealer where I get my oil changed (which was done about 3 weeks prior) they stated rear main seal went causing oil to drain from engine which also ruined my valves and threw out the timing. Gm says they'll pay 25% of total $6200 bill. Although gm has yet to return a call regarding the case I opened with them on this asking for a larger percentage.

The rear main seal broke. Causing oil to leave the reservoir and empty the engine. This was due to a frozen pvc from cold temperatures.

63 Engine And Engine Cooling problem

Failure Date: 07/13/2021

Engine started consuming oil at around 90,000 miles. First noticed after a oil change with the dealer we bought it from. Questioned them about it once we checked the oil, and noticed it being low after experiencing a engine noise. Dealer had us bring it back , refilled it, and test drove it for 20 miles. They sent it back with us, stating it may not have been topped off correctly. Noticed the issue several more times, and told the dealer , they then had us to a oil consumption test. After test was concluded recommended that the piston rings be replaced at a cost of $2202. 02. Gm first refused coverage even though this is a known issue with Terrains with the 2. 4 cyl. Engine. Dealer resubmitted to gm rep. , rep. Admitted this is a known issue, and that gm is waiting to see if they experience enough complaints to meet the 10% of production number before it is covered 100%. Contacted gm customer complaint line with no luck in getting additional coverage, even though gm extended coverage for earlier models with this issue.

64 Engine And Engine Cooling problem

Failure Date: 06/10/2021

We have had 4 transmissions since we bought the vehicle. It slows down to almost a stop after it hits 30 mph and makes weird noises all throughout the vehicle. The back right tire sticks to the pavement and jerks when I start to drive. The key ignition has been fixed several times and still sometimes won't turn with the key or come out. Yes warranty told the repaid service company to fix whatever, and they did but it still after 2 more transmission hasn't fixed the issues. Engine light and not sure what else.
