2015 gmc terrain sle awd. Suv was taking in for oil change found excessive rust on frame under all four doors. On both sides rust and holes near the front of both rear wheels. I believe its called the "rocker" I'm unsure. I bought the car at a little over 71,000 miles in 2022-2023 now just getting to 94,000 in February 2026. If there was rust which there probably was the car should have not been sold if the rust was enough to cause problem later on. I may need to go purchase a new car while still owe some money in the car loan. Rust and hole in the rear control arm. The amount to replace and repair all the parts with labor exceeds current value.

The radio dead out randomly. Which means the back up camera is non working. I wasn’t able to see a stump and hit it. Doesn’t seem safe. Like what would has happened if it was a person instead and they like the stump was in my blind spot while backing up. I feel like this is a safety issue. I have looked it up online and found out this is a common issue with these vehicles.

The contact owns a 2015 GMC Terrain. The contact stated that while driving approximately 40 MPH, there was an abnormal rattling sound coming from the engine compartment. The vehicle was taken to the residence. The contact stated that when the vehicle was started the following day, the rattling sound from the engine compartment returned. The vehicle was taken to a dealer on several occasions, and it was diagnosed and determined that the engine was low on oil and was consuming 2 quarts of engine oil every 2-3 weeks. The contact stated that the oil level was topped off. The manufacturer was notified of the failure. The failure mileage was approximately 94,000.

First occurrence in September 2015. Rear lift gate acted abnormally, when I was parked,y son opened the lift gate using the normal door handle button, it raised, but as he was loading it lowered onto him. He is small, I had to get out and pull it off of him, it went up and down a couple times and then closed. You cannot stop it from closing down on you if you are trying to load or unload into that compartment. We have had to stop using altogether.

I own a 2015 GMC Terrain, 4D. Vehicle started displaying error P0016 during the evening of 07/27/2025, the following day the vehicle stopped working. I towed the vehicle to three different mechanics. All three mechanics indicated that the engine needs to be replaced. Two of the mechanics indicated that this was a common issue with this GMC SUV and I wanted to reported. P0016 states, "crankshaft position camshaft position correlation Bank 1". I am disappointed that this issue has not been reported or recall. There are multiple youtube videos and online chats regarding this issue.

The rear hatch would open but then start to slowly drop. The local dealership diagnosed the problem and told me the pump needed to be replaced but quoted $1000. I chose not to have the repair done at that time but recently the hatch opened and then dropped suddenly hitting me on the head. There were earlier model recalls for this problem but not on the 2015. This is a potentially dangerous condition.

Liftgate strut malfunctioned. Yes vehicle is available for inspection upon request. I activated the trunk with the key fob, while retrieving items out of my trunk, the trunk began closing on me without any warning. The liftgate sensor failed to recognize an object (ME), was in the trunk and nearly caused a severe crush injury which could have been fatal. Yes the problem was reproduce by an independent service center as well as a dealership. No the part was not inspected. There were no known warning lights or messages. Apparently as per consumers this is known problem with the 2010-2017 GMC Terrain and Chevy Equinox.

Catastrophic mechanical failure; engine failure. Below freezing day driving normally until the car just died right in the middle of a busy 4 lane road. No warning lights were displayed. Luckily I was able to drift the car over to the curb lane then manually push into a parking lot with cars driving around me. Vehicle taken to independent Auto Care Service which did an inspection stating the PCV valve was frozen which then caused the pressure to blow rear seal and metal fragments could be seen in the oil drippings. No issues or dashboard notifications prior to this event.

Found steering wheel airbag deployed

My vehicle began jerking, shaking and kept shutting off in a highway intersection. I looked on the ground after coasting into a gas station to find oil leaking from under my vehicle. I've never had an oil leak and it caused my starter to go and I've had to replace the camshaft sensors all within the same week. It appears the rear seal went after the cold streak we had. I need my vehicle to take my mother to treatments, etc. Is there any recalls on this?

Oil consumption on this vehicle is terrible. All GMC for that matter. It burns in the engine and have to refill or top off multiple times a month.

Clogged manifold and engine head. Blockage buildup in manifold and Pcv valve causing exhaust problems. Oil sludge block air in head and manifold causing CEL to come on. And these vehicles drink engine oil like water. Gives code P0411

There is a well known piston ring gasket issue with various GMC Terrain model years. GMC had recalled some for the engine defect but not all years with the affected engine. The 24L Eco tec engine is faulty. The motor uses excessive amounts of oil between oil changes and all kinds of systems are affected by carbon buildup. The engines run rough and stall out WHILE DRIVING. GMC refuses to recall all of the vehicles with this problem and that includes my 2015 model year GMC Terrain with the 24L engine. This would cost me thousands to fix myself. This is a serious issue and also a safety issue that they can get away with selling such faulty vehicles to families and no one makes them fess up and fix the engines at their expense not ours. My wife has had the vehicle stall out constantly while driving and with our partially disabled child in the car. It has happened countless times to me as well. This will also eventually cause the motor to have a much shorter life. There is also a chance of the timing chain breaking and causing the engine to break. These defects should be fixed via a recall. This is a WELL KNOWN MANUFACTURER DEFECT please look it up. It affects thousands of GMC Terrains and other GM vehicles with the 24L Ecotec motor.

I GOT IN MY CAR AND PROCEED TO DRIVE AND THE POWER LOW ENGINE SIGN CAME ON. TOOK TRUCK TO MECHANIC AND PAID $1000 BECAUSE GAS WAS GOING INTO MY ENGINE.

While driving, my vehicle makes a loud funny sound, jerks/skips, and shuts off. It also loses motor oil quickly, yet it has no leaks and I have to constantly add more motor oil or get oil changes frequently. My safety has been put at risk because the engine can fail at any moment due to no motor oil, causing the vehicle to catch fire and also when the vehicle suddenly stops and shuts off in the middle of the road, it can cause an accident. There has been no inspection from the manufacturer.

I am writing to urgently request a safety recall for the GMC Terrain 2015 due to a critical issue with the lift gate mechanism, which may be both electrical and mechanical. Recently, while utilizing the lift gate for routine activities such as grocery shopping, a terrifying incident occurred that endangered the safety of my family members. Upon opening, the lift gate exhibited a concerning behavior, forcefully closing without warning or control, posing a severe risk of injury. Despite attempts to intervene, the gate continued its downward motion unabated, presenting a serious hazard of crushing limbs or causing incapacitating harm. In a frightening moment, one of my family members narrowly avoided a potentially catastrophic injury as the gate threatened to strike her right hand. While I sustained a minor injury to my arm, a superficial wound, the gravity of the situation cannot be understated. This dangerous malfunction persists, rendering the trunk unusable out of fear for the safety of myself and my loved ones. Given the potential for life-altering injuries, I implore you to take immediate action and initiate a recall for all GMC Terrain 2015 models affected by this defect. The safety of consumers should be the utmost priority, and failure to address this issue promptly could result in devastating consequences. I urge you to prioritize this matter and take decisive steps to remedy the situation before further harm occurs. Your swift action in initiating a recall will not only safeguard the well-being of countless individuals but also uphold the reputation of your brand for prioritizing customer safety.
