general problems of the 2016 GMC Terrain

My vehicle started turning off suddenly when stopped and then when starting to move. I replaced my rear seal. A week later, I have oil in my timing and my engine no longer works. I have had it checked by a shop. No warning was given. I have my oil checked regularly and changed on time. I had a car full of people, adults and children, in rush hour traffic. The car is sitting in my driveway as I will need to negotiate with the lender on money owed. I am currently without a safe vehicle to drive, and I need that as I am a caregiver and home aid.

Excessive oil consumption. . . . Caused engine to fail. . . . Yes, car is available for inspection . . . Caused the car to lag and initially break down without any warning lights . . . Confirmed form dealer new engine needed. . . Law suits in other states have proven that this seal problem has been known to GMC for years and they haven't repaired these faulty parts. . . Again, no warning lights came on. . . Please assist.

Carr paused, and then stopped in the middle of the highway, without any warning lights or identifiers. Other vehicles had to come to abrupt stops or even veer to avoid hitting me the manufacturer is aware, and has had a large lawsuit settlement due to a faulty rear seal causes massive internal oil consumption without any warning to the operator of of the vehicle. My research has shown that it is a catastrophic common issue with this vehicles model and year a certified GMC dealership has identified this as the reason for the sudden shut down without warning, not one warning light illuminated to indicate low or any other issue. The car has had regular oil changes and maintenance. This well-known defect should normally be caused for alarm and the safety of drivers would also for a mass recall.

I bought the vehicle in November of 2025. No warning lights or problems running. Check the engine oil upon purchase and have the dealership sticker showing oil change was recently done and oil showed that it was full. Approximately 3 weeks after purchasing, the car starting idling rough and stalled a few times during my commute to work. The check engine light came on and it showed that the vvt was a possible solution for the code p0014 this was on December 12th 2025. I replaced the suspected part with no change in vehicle condition. I checked the oil and found that it was empty/no oil on dipstick. I had to add 5 quarts of oil and then it showed it was in the safe zone on the dip stick. Today (January 15th 2026) I checked the oil again and it showed no oil on the dipstick. I had to add 2 quarts for it to be at the bottom of the safe zone on the dipstick.

I check my oil every time I get gas as to ensure that I don't go below the threshold for the oil, as I know these engines have an oil consumption issue. My Terrain started having a loud grinding sound after losing power on the highway and I was able to pull off before the car died completely over 60 miles from home. I have since changed the upstream, and downstream O2 sensors (they needed it), vvt solenoids, and now going to be required to change my catalytic converter because the excessive oil consumption has clogged it almost completely. Why will gm not issue a recall for this engine and get it fixed, when they have knowledge that there is an issue. A recall was issued for previous years (on the same model) having the same issue, but yet we are left to "figure it out" at our own expense? come on gm and the NHTSA, get it together and issue a recall already, you have all the complaints, and history you need to start one.

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.

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!!!!!!!.

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.

When starting the vehicle, I received a “reduced power” warning and then the check engine light came on. I was afraid to drive it to the service center, so it was towed. The repair center informed me that the timing chain failed and that engine will no longer start at all. I cannot afford to have the engine repaired no matter the cost because I’m still responsible for almost $6k of the loan for this vehicle, in addition to full coverage insurance required by the lender. Also, probably taxes as well because I now have a very expensive lawn ornament. Oh, and towing fees to deliver the ornament to the lawn. And then there’s the cost of finding transportation so I can actually work to throw money at all of those costs. Being buried financially because I put faith in this product is an injury and an expensive lesson.

The contact owns a 2016 GMC Terrain. The contact stated while driving at an undisclosed speed, there was a knocking noise heard coming from the front of the vehicle. There was no warning light illuminated. The contact had the vehicle was towed to the residence and then to the local mechanic where a diagnostic test was performed. The local mechanic stated that the rear main seal needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not made aware of the failure. The approximate failure mileage was 84,394.

The contact owns a 2016 GMC Terrain. The contact stated while driving approximately 45 mph, the vehicle lost motive power and stalled. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the timing chain had failed, and the engine needed to be replaced. The vehicle was not yet repaired. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 104,000.

Driving down the road yesterday and outta nowhere I lost power and got a low oil pressure warning then the car just shut off merging onto a busy highway. Blown rear main seal and locked up the engine with no warning. Only 65k miles on the car. Dealership wants to charge me 11k to replace the engine. This is a very common occurrence with this vehicle I’m reading now. This could’ve caused a major accident.

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. ) [xxx] [xxx] class action lawsuit about previous model years: [xxx] v. General motors information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This is a 2016 GMC all wheel Terrain. Over the past several years when accelerating the car would shake violently, because we could not reenact dealership could not diagnose the problem ,however as the issue has gotten worse we have been able to recreate and diagnose and we are looking at a $2,000 repair based on a known issue which did not lead to a recall. The actual engine in its entirety shakes violently when accelerating!! how in the hell is this possible that these cars are allowed on the street without a recall. You should be ashamed!.

The engine - my engine blew because oil evaporated out of the #1 cyclinder, which drained the oil. No warning lights went on and the vehicle stalled in the middle of rush hour traffic. The dealership told me it was because of a factory defect, but no recall on that part of the vehicle. This could have been much worse if the vehicles behind me were going faster than they were and not able to stop before rear ending me. Because this was a factory defect it should have been recalled and I should have been notified of this problem when I bought the vehicle.

Excess oil consumption.

Thermostat/coolant sensor malfunctioning causing engine fan to constantly run as if the engine is over heating. Some engine exhaust door/flap is stuck open or closed causing check engine light to come on. And or the actuators doors are broken causing windows to fog and obstruct view. Not sure what would cause this issue but I have had to have work done on my vehicle twice for this issue within 3 years.

Was driving home from work and the engine light came on. Shortly after the stabilitrak warning light came on followed by the reduced engine power warning. I had a gm dealer work on why the engine light came on while the car was still under warranty and I thought that would have fixed it. I have been reading on articles how the engines in these models are defective and consumes a lot of oil. I always have to add oil in between changes. I had a mechanic look at my car and run a diagnostic and basically the pistons need replacing. . . Due to the defective engine. I feel the engine repairs that will be needed should be covered.

The contact owns a 2016 GMC Terrain. The contact stated that while operating the vehicle, an abnormal oil odor was present inside the cabin of the vehicle, causing the driver to experience a headache. Additionally, while driving the vehicle was shaking and vibrating. The vehicle was later towed to the local service center who diagnosed that the engine was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure. The failure mileage was 67,496.

Timing chain went out, at 80,000 miles, causing vehicle to stall.

The contact owns a 2016 GMC Terrain. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power.

The VIN was unavailable.

While just starting on my way home on a cold 9 degree day,I have an 2016 GMC Terrain that I had since 2018 and bought from a dealer. After driving for about 12 miles on the interstate the Terrain engine light came on and there was a vibration coming from the front of my GMC. There was an exit ramp about 1/4 mile so I pulled off the interstate and my vehicle showed loss of power and steering and shut down, barely made it on the exit ramp. Very dangerous not having steering with little notice. I noticed alot of oil dripping from the undercarriage so I called a local automobile shop to get my vehicle towed. They diagnosed that I needed a new engine and comented that the 2. 4 engine had many issues. I recently had it towed to my house and currently going to have a local chevy dealer give me a second opinion and cost for repairs since I still have a loan on the vehicle. I believe that this is a very unsafe vehicle and needed to be reported so nobody gets hurt. Thank you.

At approximately 75000 miles the car began leaking oil. Took it in to gym certified dealer. Was told the pcv froze causing a pressure build up, and blew out the rear main seal. They stated this engine has this as a common occurrence. Searching online this appears to be true. Many years prior to mine were recalled. Apparently the recall needs extended.

I was leaving the area of hiram and my car started running different and you could hear a taping noise. I drove it to the GMC dealer down the street and they said it was the timing chain. I recently had an oil change and I was wondering if that could be the problem. The dealer gave me no recommendations or indications that I needed to change belts or components and my service engine light has never came on.

2016 GMC Terrain slt, service engine light came on, vehicle stalled many times, restarted but drove and misfired, stalled again, was able to get it to repair garage who I trust. He checked code and said I had to put a complete timing chain kit. Total cost came to $992. 36 and didn't have a vehicle for a week due to weekend and a holiday. The vehicle only had 30,763 miles on it at the time but was out of factory warrantee. Reading other customer complaints, this looks like an ongoing problem and I feel should warrant a recall. Additional info such as repair invoice is attached. Please reply when received and thank you for your time.

I have to put oil in my car every 2 weeks. There are no leaks. The engine is burning oil.

On may 17,2021 I took my 2016 GMC Terrain for a oil change I have only had my vehicle for about 2 months and I have noticed that it burns way too much engine oil on may 17th 2020 it had a full 100% engine oil now today is June 22 of 2021 and it has 60% oil engine.

When driving the stabiltrak service light will come on and the engine light. The car will loss acceleration immediately then seems wont go out of 2nd gear. I stop turn off car a few minutes and it will start again and the engine light will go out after while. Last time the car would not start again. It finally did after 20 minutes or so. And light went out layer. Took it to dealer once and they could not duplicate problem. This is worrying me.

Less than 62,000 miles and the transmission has gone out. After searching to order the parts, I noticed several complaints come up across numerous websites where owners state that their vehicles transmission has died around 60,000 miles. This tells me GMC is at least aware of this issue and should enact a recall for this problem. The parts should be covered by GMC.

Tl the contact owns a 2016 GMC Terrain. While driving approximately 12 mph, the contact heard an explosion from the front of the vehicle. The contact quickly exited the vehicle and smoke began to emit from the engine compartment. The vehicle was towed to the contact's home and then to circle Chevrolet (4134, 641 shrewsbury Ave, shrewsbury, NJ 07702, (732) 741-3130). The dealer diagnosed that the engine block was damaged. The manufacturer was not notified. The failure mileage was 18,491.

I have been driving my vehicle when on three seperate occasions the service stabilitrak message flashed on the dic and I lost engine power. One of the times this happened I was on a road where the speed limit was 55 and the issue almost caused a vehicle to crash into me. The message goes away after about 5 minutes. I tried taking it to the dealership twice and was told they cant replicate the problem so now I dont even bother trying to have them fix it. How can a major safety issue like this not be fixed by gm!!.

I tried to start my car and it wouldn't start. This happened on a Sunday so I had to go to a place that was open. I had my car towed there and come to find out it was the solenoid. I had to get that replaced and also a fuel pump. This was the first problem.

Tl the contact owns a 2016 GMC Terrain. The contact stated that when the key was removed from the ignition switch, the engine did not shut down. The contact had to insert the key into the ignition switch several times to shut off the engine. The vehicle was not taken to a dealer for diagnostic testing. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 30,000.

2016 GMC Terrain will show the check engine, traction control and service stabilitrak lights after gauges jump up and down. Vehicle will then go into neutral and then suddenly slam into 2nd gear. This occurs at high rates of speed on the interstate, as well as, normal roads. The vehicle will then stay in 2nd gear and will not go into another gear when it is placed in manual either. Sometimes, after restarting several times, it will drive normally. Other times, it will not start once it is turned off. I have had it to the garage five times in the last month. The starter wire and starter relay have been replaced, loose ground wire tightened, and the ecm replaced yet the car continues to repeat the same cycle. Car currently has 53,300 miles on it.
