2017 GMC Terrain engine complaints
Page 3 of 4: complaints 41 to 70 of 81, newest first, as owners wrote them.
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.
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?
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.
Rear oil seal failed resulting in engine oil pressure loss and vehicle was stopped in middle of roadway
It's a known problem with gmc with a lawsuit for the PVC pipes clogging and blowing the main rear oil seal causing the vehicle to quit running
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.
The contact owns a 2017 GMC Terrain. The contact stated while driving approximately 65 MPH, the vehicle started losing motive power. The contact was able to pull to the side of the road, and the vehicle stalled. There was no warning light illuminated. The vehicle failed to restart after several attempts. The vehicle was towed to an independent mechanic, who diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle was repaired; however, the contact stated that the vehicle was experiencing an abnormal oil consumption after the engine replacement. The contact stated that there was no evidence of an oil leak. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.
Engine shut off while doing 70 mph on interstate. There was no warning signs or nothing.
1. The car started making a noise then started surging and jerking. I'm not a mechanic, so I don't know what happened but it will not crank now. Yes, someone can come inspect the vehicle, by appointment only. 2. I was afraid that the car was going to blow up or the brakes would not hold. 3. No, the problem has not been reproduced or inspected. 4. No, the vehicle or component has not been inspected. 5. NO, there were no warning lights to let me know there was a problem.
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.
The contact owns a 2017 GMC Terrain. The contact stated while driving at approximately 40 MPH, the check engine warning light illuminated, and the vehicle failed to remain idling. The vehicle was driven to the residence and parked. The vehicle was not able to be restarted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the issue. The failure mileage was 79,500.
The engine burns oils twice as fast as it should and gives no warning of a problem. I am 3 years into payments on this vehicle and the engine is shot due to this issue. I have under 80,000 miles but this is a major problem that GMC is not addressing its very frustrating I will have to pay off a damage car they sold and now buy a new for an obvious problem they won’t acknowledge
Due to cold weather the PCV froze which caused pressure to build up in the vehicle’s crankcase which caused the rear main engine seal to pop out. Results in losing all engine oil without and warning driving down the highway. I was lucky enough to get off the highway but currently without a vehicle due to possible engine damage
Engine seizing at highway speeds cause oil to blow out the rear main seal…
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. Had car towed to dealer- pvc port plugged causing oil pressure to blow out rear main seal losing all oil causing damage to the engine and components. Warning lights did not come on until damage was done. Discovered it was a known issue with this engine and class action lawsuit has been filed. Was fortunate we were not on the road when this happened.
The contact owns a 2017 GMC Terrain. The contact stated while driving 5 MPH and merging into traffic, the vehicle stalled. The contact stated that the check engine warning light was illuminated. The vehicle was not drivable. The contact towed the vehicle to an independent mechanic and was informed that the timing chain had fractured, and the engine needed to be replaced. The vehicle was not repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 79,000.
Vehicle has 37,000 on it and the timing belt/chain is bad causing value problems.
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.
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.
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.
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.)
2017 gmc Terrain. vin -[XXX] on 12-26-2023 milage - 80694 Catastrophic failure involving PCV Valve and blown seal that destroyed the motor. So ...why or even how are we discussing rear main Seal. This is COMPLETELY UNACCEPTA,BLE. I have 2 kids starting to drive the repair estimate is $8.000 to $10.000 INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
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.
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
It was Christmas weekend, the coldest days our area had seen this time of year in decades. Temperatures were around 0 degrees, with wind chills that were -25 below. The check engine light had come on the day before. My husband was literally driving to the mechanic to have it looked at, when the vehicle completely broke down across the street from his destination. Thank God he was approaching an intersection when it died, and not traveling at a higher rate of speed, where he could have been injured, or others on the roadway around him could have been injured. We had the vehicle towed to our GMC dealership where we purchased it just three years prior. Upon inspection from the mechanic, it was determined that the PCV valve was plugged causing pressure on the rear main seal, which then blew out, bending the valve covers, breaking the timing chain, the water pump chain, and damaging the head gasket. The whole bottom of the motor was covered in oil. Absolute catastrophic damage!! I’m told the cost to replace these parts to essentially rebuild the engine, would start at approximately $4000. A brand new engine would be about $11,000! This entire situation to me is just unbelievable! A five year old GM vehicle, with just 46,000 miles on it! This should not have happened. In researching, I’ve been made aware that this is a common issue with GMC Terrains. In fact there was Technical Service Bulletin made by GM for 2010-2013 models whose PCV valve would clog causing rear main seal blow outs. The holes were so small in diameter, technicians would use a 1/16 drill head to clean it out. This is an obvious manufacturer defect that apparently hasn’t been resolved in the newer model Terrains. How has this not been a safety recall yet?? Shame on you GM! This will be the last GMC vehicle I will own!
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
The contact's wife owns a 2017 GMC Terrain. The contact stated while his wife was driving 40 MPH, the vehicle started to stall, and shuddered inadvertently. The check engine warning light was illuminated. The contact met his wife at the scene and noticed that oil was leaking from underneath the front end of the vehicle onto the ground. The contact refilled the engine oil and his wife was able to drive the vehicle to their residence; however, oil continued to leak while she was driving. The contact refilled the engine oil and the vehicle was taken to the dealer, where it was diagnosed that the rear main seal was fractured and had failed. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that there were no recalls associated with the failure; however, the manufacturer offered to cover 13-percent of the repair cost. The failure mileage was approximately 94,000.
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.
