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.
The contact owns a 2015 GMC Terrain. The contact stated while driving 70 MPH with cruise control activated, the RPM suddenly increased to redline, after which the vehicle lost motive power. The contact was able to coast to the shoulder of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the positive crankcase ventilation (PCV) valve, which then caused a failure with the front crank seal, resulting in damage to the engine. The contact was informed that the engine needed to be replaced. The vehicle was repaired. After investigating the failure, the contact related the failure to NHTSA Action Number: PE25001 (Engine, Engine and Engine Cooling). The manufacturer was notified of the failure but provided no assistance. The failure mileage was 148,000.
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.
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?
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.
The contact owns a 2015 GMC Terrain.

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.
The contact owns a 2015 GMC Terrain. The contact stated that after starting the vehicle, the message "Power Reduction Mode" was displayed, and the vehicle stalled. The contact stated that after restarting the vehicle, there was a ticking sound coming from the engine compartment before the vehicle stalled another time. The vehicle was towed to the local mechanic who diagnosed the vehicle and determined that the engine timing was faulty, and the engine had experienced a loss of engine compression. The contact was advised to contact a local dealer for service. The vehicle was not repaired. The manufacturer and local dealer were not yet contacted. The failure mileage was 160,000.
Terrian with 2.4v have a massive oil burning problem. I have to put at least 2 quarts of oil in my car a week to get oil in it. There is problem with them during oil or oil rings are junk.
Vehicle has been consuming oil quicker than normal with no known reason as to why. Vehicle has also had 2 incidents of the vehicle not starting and no engine light or codes appear after vehicle gets started.
The rear main seal for the engine fails because of a clogged PCV valve. This was a problem on previous years for the Terrain and other vehicles that carried a similar type of engine. There was a recall for those previous years (2011-2014). My vehicle is a 2015 GMC Terrain, and I am currently experiencing the same issue. I took my vehicle to a licensed dealership and they quoted me a price of close to $3,000 to make the necessary repairs. In my opinion, since the same issue/problem is occurring, there should be a recall issued to include at least the 2015 year models for that engine.
Oil drained and no oil after oil change ra about 2300 miles and there is no indicator for low oil level or anything. Engine started rattling and engine sounded so that I pour oil then no more sound and working About month ago engine stopped while going slow in school line and after resting it worked and same rattling sound because of no oil
The contact owns a 2015 GMC Terrain. The contact stated that the vehicle failed to start up as needed. The vehicle was towed to an independent mechanic where it was diagnosed that the engine needed to be replaced due to oil not reaching the engine block and the engine burning. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 106,000.
Vehicle stalled, steering column was shaking. Fortunately, this took place when leaving work parking lot. Had it happened on the road, driver and passenger safety would've been at greater risk. In addition, this particular issue could've resulted in a fire in the engine compartment. Took to mechanics and was informed that cylinder #3 was no longer contributing to engine function. Technician discovered cylinder was leaking from exhaust valves. Vehicle has not been inspected by the other individuals. Prior to this incident, vehicle was consuming oil at an enhanced pace although the oil light indicator would never turn on. Engine light didn't appear until cylinder #3 failed. It's important to note there is a previous (successful) class action lawsuit for the 2010-2013 models for the same exact reasons noted above. Missouri is in the process of filing a lawsuit for the 2014-2017 models.
Engine started sputtering, then vehicle was shifting hard and occasionally jerking forward while braking/at a complete stop. Check engine light came on. Found there was no oil left. Was less than 3000 miles since prior oil change. Dealer service sticker stated oil change was not due until 5000 miles (synthetic). Oil light never came on. After refilling oil, check engine light turned off and vehicle started operating normally. Discovered many others with problems with this vehicle consuming oil. Luckily, we caught it before engine failure, but obviously worried that this could happen at any time.
