2017 GMC Terrain Problems

Have had to replace the VVT solenoids several times within a year spam. Had to replace the rear main seal because it blew out due to carbon build up. Having issues with excessive oil consumption. Now the vehicle just started with: going from a stop position to accelerating at low speeds the vehicle stalls and dies. I want GM to take accountability and fix this issue as it is a safety issue to myself and everyone on the road.

The contact owns a 2017 GMC Terrain. The contact stated that after the vehicle was taken to a local car wash, while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the residence; however, the next day, the vehicle hesitated while starting. The message "Stabilizer - Power to Engine Reduced" was displayed. The vehicle was taken to a local independent mechanic, where it was diagnosed, and it was determined that the engine possibly needed to be replaced because the engine failed to turn over. The vehicle was towed to a local dealer, where it was diagnosed, and it was determined that the engine was blown. The contact was informed that the engine and the starter needed to be replaced. The vehicle was not repaired due to the cost and remained with the local dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 104,750. The VIN was not available.

I am filing this complaint to report a catastrophic engine failure involving my 2017 GMC Terrain equipped with the 2.4L Ecotec engine, which I believe is the result of a known manufacturing defect related to excessive oil consumption and premature internal engine wear. At approximately 88,000 miles, my vehicle experienced severe engine failure, including excessive oil consumption, timing chain failure, and complete engine failure, which has been confirmed in writing by a licensed repair facility. The shop determined that the engine failure was caused by oil starvation resulting from excessive oil consumption, leading to internal engine damage and timing chain failure. This failure occurred without warning and rendered the vehicle unsafe to operate. Sudden engine failure creates a serious safety risk, including loss of power while driving, inability to accelerate, and increased risk of collision. This engine failure matches a well-documented defect pattern involving General Motors’ 2.4L Ecotec engines, which have been the subject of class-action lawsuits, settlements, and jury verdicts related to premature piston ring wear, excessive oil consumption, and resulting engine damage or failure. These issues have been widely reported in Chevrolet Equinox and GMC Terrain vehicles within my model year range. My vehicle was properly maintained, and this failure was not the result of neglect, misuse, or normal wear and tear, but rather a latent manufacturing defect that manifested after the warranty period but well within the reasonable life expectancy of the engine. I am requesting that NHTSA formally document and investigate this defect, as it presents a significant safety concern for drivers operating vehicles equipped with this engine. I also request that General Motors be required to address this defect to prevent additional engine failures and potential safety incidents.

We have been keeping up with all maintenance and oil changes. We have only driven the car for less than a year. At time of oil change; the oil has been low, resulting in OVER oil consumption; Requiring an extra quart of oil to be added between oil changes. When we purchased the vehicle, there was an strong exhaust smell; The shop that we bought the vehicle stated there were no issues and we have taken it to them multiple times an hour away from our home. The car completely shut off while my minor son and I were driving. Placing both of our lives at risk! It would never start back up. Now the car has seized and requires an engine replacement. It is sitting at a local garage while we wait for the dealership to help us, to no avail.

I was driving back home when I suddenly heard a loud pop and my car seat belt immediately tightened up. I saw smoke inside the car and the screen in my dashboard said "airbag service" There was no air bag physical deployed in the car so I believe it happened internally. Now my driver seatbelt will not retract and the front passenger seatbelt will not come out.

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.

The head unit quit working around 98k. The head unit is the radio, and screen which includes the back up camera. From what we have been told and find online, this is a known problem with them and affects other models as well. For the most part the head unit doesn't work but once in a while, once a month, it comes on but shows the Chevy logo on the screen which is odd because it is a GMC. Once you turn the car off, it will be gone again until it decides to come back. We took it into a dealer who tried to hook up to it and reprogram or update it, but he had no luck. Now we are without a backup camera that is a safety issue. I do not know why this isn't a recall as it is well known about issue.

I looked up my recall on my vehicle about my headlights being recall. Never received any information there was a recall.

The contact owns a 2017 GMC Terrain. The contact stated that the vehicle was taken to the local dealer to be serviced under NHTSA Campaign Number: 22V137000 (Exterior Lighting). After the recall repair was performed, the contact discovered that while driving at night, the low-beam headlights illumination was extremely low, creating a visibility hazard for the driver. The vehicle was taken back to the dealer who indicated that no failure was found, and that the headlights operated as intended. The manufacturer was notified of the failure. The failure mileage was 54,000.

The latch for the rear hatch/door does not release every time. There have been instances when itmes have been in the cargo area and when the button is pressed, it will not release the latch. This causes someone to have to crawl over the back seat to retrieve the items from the cargo area. This also is causing my son to have to store items, that would normally be in the crgo area, on his back seat. I owned a 2015 terrain and had this same issue. The latch was replaced but still did not operate correctly.

The contact owns a 2017 GMC Terrain. The contact stated that whenever it would rainwater would leak into the vehicle underneath the dashboard on the passenger side of the vehicle causing water to leak onto the occupant's feet and onto the carpet. The contact had taken the vehicle to the dealer who resealed the area. The failure now occurs on the driver's side of the vehicle. The contact stated their appointment for the driver's side had not occurred as of yet. The manufacturer was not made aware of the issue. The approximate failure mileage was 48,000.

Wiper blades transmission plastic parts keep popping or breaking this is the THIRD time this has happened at a cost of $350. Why would you use plastic parts for this knowing that it will break easily? Who can afford to keep replacing this? 12

On5/3/2022 we were driving on I65 around Shepherdsville KY. It was pouring down rain and our windshield wipers stopped working and stuck in the up position. We had a semi on each side of us. This made it even more difficult to see due to the rain coming off of their tires and spraying onto our window. We had to slow down to a dangerous low speed on the interstate due to the difficulty seeing. We made it to the shoulder after almost being hit by a semi We had to sit there until the rain stopped. This was extremely dangerous in itself being that it was on an interstate with high speed limits. We had no choice but to stop in the town of Shephardsville and get a hotel room. We are still trying to make our way back home at this time to IN. This has not been expected by anyone at this time. There were no warnings of any kind.

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.

I had a message flash that said the power to the engine was reduce. Next message said check stabilink ( or something similar).. it said drive with caution. I live 2 mins from my job I drove home and pulled in the driveway I then felt the car act like it wanted to shake. This was on 2-10-26 I contacted onstar asked them to run a diagnostic. The codes that came back P0016 p0089 p228D are very well known codes with many people with the same vehicle/engine that have had to replace the engine. The engines have known issues had I known that maybe I could have replaced a part or two or three or four to have a stable vehicle now my vehicle is currently at GMC DEALER since Tuesday morning actually had it towed there monday night. I called Wednesday evening they still wasn't sure the "issue". Thursday I wait until about 1pm spoke with John he said well we are pretty sure you need a new engine the mechanic is checking a few more things the car has no pressure. About a hr later I get a email and a call saying the timing chain skipped and something about the pistons and the valves and I need a new engine . John called me and said well.Ill tell you what we will offer you a brand new Engine for the same price as a rebuild plus you get 3yrs 300 thousand warranty for 10,944. Give or take a few dollars. We'll first I paid like 15,500 for the car that I just litetally paid off like Jan 12026. I really feel like had GMC Made buyers aware that the vehicle has defective parts/engines buyers could replace parts or GMC should be held accountable. I started googling the engine and found out that there is a class action lawsuit and a recall on " certain" 2017 terrains depending on the vin. Same issues my car is having but its saying my car has no recall.

Throttle position system all of a sudden went bad. My 2017 Terrain started shaking. I was holding up traffic. The sun couldn't go over 5mph. I've read online where this is happening alot in 2010'2017 GMC Terrains.

I was driving back home when I suddenly heard a loud pop and my car seat belt immediately tightened up. I saw smoke inside the car and the screen in my dashboard said "airbag service" There was no air bag physical deployed in the car so I believe it happened internally. Now my driver seatbelt will not retract and the front passenger seatbelt will not come out.

While in park and driving, the passenger seat belt locks and will not unlock. You must unfasten belt and refasten it. It does this multiple times during a trip. This has occurred since 2020.

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?

I AM THE OWNER OF A 2017 GMC TERRAIN. YESTERDAY, I WAS INVOLVED IN A CAR ACCIDENT IN THIS VEHICLE. SOME PERSON PULLED OUT IN FRONT OF ME AND I SLAMMED ON MY BRAKES TO AVOID A CAR ACCIDENT. HIS VEHICLE CONTINUED THROUGH AN INTERSECTION IN WHICH HE DID NOT HAVE THE RIGHT AWAY CAUSING ME TO HIT THE FRONT END OF HIS TRUCK. AS THE DRIVER STATES HE DID NOT SEE ME, I CAN CONFIRM I SLAMMED ON MY BRAKES, WHICH ACTED AS THEY COULDN'T STOP. IT FELT AS THE BRAKES WERE NONEXISTENT. THIS WAS AN EXTREMELY TERRIFYING MOMENT, AS I WAS GOING 45MPH (PER THE SPEED LIMIT). AS I HAD READ EARLIER, THE 2018 TERRAINS ALSO SEEM TO HAVE THE SAME PROBLEM.

The power steering assembly failed and caught on fire. This then caused the engine to malfunction and no longer work. This happened while driving on the interstate at a speed of approximately 80mph. No prior check engine lights were visible

MY CHECK ENGINE LIGHT CAME ON ALONG WITH A A MESSAGE THAT STATES 'REDUCED ENGINE POWER' AND A MESSAGE READING 'SERVICE STABILITREK WHEN I WAS DRIVING ON THE HIGHWAY AT 70 MPH. THIS CREATED SUDDENLY JERKING AND SLOW ACCELERATION SO THAT I HAD TO PULL OFF THE ROAD. I FOUND A FORUM AT [XXX] THAT REVEALS THAT THIS HAS BEEN AN ISSUE WITH GMC MODES AT LEAST AS LONG AS 2011. THE DURATION FOR WHICH THIS HAS BEEN A PROBLEM WITH GMC MODELS, AND THE FACT THAT STABILITREK IS AN INTEGRAL SAFETY FEATURE OF THE VEHICLE IN AVOIDING ACCIDENTS SEEMS TO MERIT A RECALL.
