2016 GMC TERRAIN Complaints

WHILE DRIVING IN A HEAVY RAIN IN A CONSTUCTION ZONE, WIPER QUIT WORKING. Never notified vehicle had a wiper linkage failure issue. Paid for repairs out of pocket and GM won't compensate because a GM Dealer didn't perform repair. See Service Bulletin N192266180-01, thank you!

My vehicle started shaking & stalling really badly out of nowhere on April 18, 2025. Had to have it towed to GMC dealership. They said the engine was showing low compression. Got timely oil changes and everything on this engine. The check engine light nor any other warning light ever came on when this happened. After some research, the engine in my car, the 2.4 L engine on the 2014 - 2017 models of the GMC Terrain has known defects which although GMC has known about, they have done nothing to address the issue. There was no prior warning that the engine was failing. It was very sudden and I was in traffic when this happened putting both my safety and the safety of other drivers and pedestrians in danger.

I am reporting excessive oil consumption in my 2016 GMC Terrain with the 2.4L Ecotec engine. The vehicle burns through an abnormal amount of oil between routine oil changes, often requiring additional oil changes without any visible leaks or dashboard warnings until the oil level is dangerously low. This issue has been diagnosed by a certified GMC dealership, but the repair was not covered under warranty. I’ve learned this is a known and widespread defect related to faulty piston rings and PCV system issues in this engine model, which has led to engine damage or failure in many cases. GMC has not issued a recall for my VIN, and my request for goodwill assistance was denied despite the safety risk of low oil pressure and potential engine failure while driving. I believe this issue poses a safety concern and warrants formal investigation and potential recall expansion.

My 2016 GMC Terrain exhibited the excessive oil consumption outlined in both of the following Special Coverage Adjustment bulletins. In addition to the excessive oil consumption, the oil light and oil pressure warnings never gave any indication that there was an issue or that the oil was low. This ended in the engine shaking the whole car, jerking it forward when stopped, and causing the engine to seize and need replacing. GMC customer service has refused to acknowledge this issue, stating that until the government tells them to issue a recall, they can't do anything to fix my vehicle. GM acknowledged the issue for model years 2010 - 2013 (+2014 later) and alleged that they made production changes in 2013 that fixed the issue. From the experience with my vehicle and the posts on multiple consumer websites by other GM owners, it is clear that they did NOT fix the issue and that there are hundreds of owners of GMC Terrain and Chevy Equinox vehicles with the 2.4L engines that have had this problem and have lost all the value in their vehicles as a result (or had to pay up to $10,000 for a new engine.)

consumption of oil! I got my oil changed January 1, 2025. It is now February 1. I have driven less than 500 miles. I had no oil. I have no Leaks or anything wrong. The car just consumes . I have had to have 6 oil changes in the past 3 months. Shop after shop. Has said it just consumes oil and this vehicle is trash. I noticed there was also a lawsuit against it. If you do not put a recall out on my vehicle ASAP, I am going to file a personal lawsuit and sue the hell out of you! For your scam! Somebody better give me a call immediately. Or set me up at my local GMC dealer to fix this issue. I better be expecting a notice in my mailbox or an appointment for a free fix and this better be a recall immediately! Or you’re asking for another lawsuit! I was told my car could blow up. With my kids and it could kill us! You better fix this immediately!!!!!!!

I was driving my vehicle to the gym when I noticed it was driving weird, it would not accelerate like normal, was having a hard time getting going and was making a weird noise. I had just put some oil in the car because we had known for a little while that it had a problem with burning oil because of the make and model (as told by other mechanics previously), when I got to the gym I heard a pop noise and the car stalled on me, I eventually got it started up again after 2 hours of being stranded at the gym. The next day I had to drive 40 minutes away for nursing school Clincial where on the way home it was back to driving weird and making a loud horrible noise from the engine. I was only 5 minutes from home when it was really bad and once there I noticed the burning smell from the engine. When I checked the oil level after an hour and half of cooling down I could not get any oil reading on the dipstick, after adding almost 4 quarts there was still no reading on the dipstick. We finally drove the car to my mechanic (8 minutes away) and it was already back to making the loud noise, having trouble accelerating, and producing the foul odor. I was told the PCV was restricted and caused the engine to over pressurize and that lead to the Main Rear bursting and all the oil in my car being thrown over the entire underside and probably the roads. They also checked the oil filter in the car to see if the engine itself was salvageable, where they found metal flakes in the oil filter and deemed the engine failed and are saying the engine needs replaced in order to fix the car I’ve had for 15 months… I’m still paying this car off and I have only driven it for less than 17,000 miles. It is a 2016 GMC terrain that only has 91k miles, I truly hope GM makes this right seeing as so many have come with the same exact problem due to poor design and vehicle quality. My car has had regular oil changes and I check the oil every week because of the prior burning problem.

The contact owns a 2016 GMC Terrain. The contact stated while driving at an undisclosed speed, the vehicle shook abnormally and lost motive power. The contact restarted the vehicle, and the low engine oil warning light illuminated. The vehicle was driven to the shoulder of the roadway. The vehicle was towed to the residence. The vehicle was scheduled for a diagnostic test at the dealer. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. In addition, the contact stated that the vehicle had recently received an oil change at Walmart. The manufacturer was not made aware of the failure. The failure mileage was unknown.

Code p0700 was indicated at a professional transmission shop. My vehicle started driving different. It is a scary feeling. I have a ten year old daughter who I commute to school and safety is the utmost of importance. I don't want to have a accident in a vehicle I recently purchased for safety and end up having to look for another vehicle because of a total loss accident or a transmission problem that would cost a lot of money I don't have. My fear is the gears slipping as I drive my daughter to school. I got a quote of close to 3,000 $ to have the transmission rebuild or fixed. Money that I don't have to give a shop for a vehicle I purchased to not have problems like this. I called GMC to make an appointment to perform a transmission flush. The p0700 code indicates TCM failure. This is a very nerve wrecking situation. Please help me .

My steering wheel locked while driving. This has prevented me from turning the wheel AT ALL (100% completely locks while the car is in motion). The locked steering wheel lasts approximately 15 seconds. This has happened multiple times over a few month period. I took it to GMC who couldn't replicate the issue and said that GMC no longer makes the steering column assembly component, which they aren't sure would fix the issue, so there was nothing they could advise be done other than sell the car or spend a lot of money on diagnostic fees, which they said they wouldn't do if it were them. My safety and those around me were put at risk because I lost steering function while the car was in motion. The only option was to break and stop the vehicle. There were no warning lights or other indicators to alert of an issue.
