2017 GMC Terrain Power Train

My car lost oil while I was driving. I also lost power. I had my car over to a garage and the mechanic diagnosed it was a ruptured rear main seal caused by a frozen PCV system. GM knows about the problem but has not recalled it. It is very expensive to repair. And because the manufacturer knows about it but never told the consumer, is fraudulent.

My vehicle only has 78,000 miles on it and the timing chain needs to be replaced?! This is no longer under warranty because it’s been over 5 years but this should last a life time. Now I have a car that doesn’t start or run that I have to make payments on and no one wants to do the work on my car! I looked online and a bunch of people are having the same issue with the same exact car at similar mileage and the same issue! GMC needs to do a recall on this issue, many people are losing money and it’s a financial crisis.

The contact owns a 2017 GMC Terrain. The contact stated that while her daughter was driving at an undisclosed speed, she observed white smoke coming from the vehicle, and the vehicle lost motive power. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who determined that the vehicle was consuming an excessive amount of engine oil. The vehicle was not repaired. The vehicle was taken to another independent mechanic, who confirmed the diagnosis. The vehicle was not repaired. The manufacturer was notified of the failure but did not assist. The failure mileage was 125,000.

I have to replace my rear drive shaft.

I was on the interstate, heading out of town. I heard a loud noise from under the car. The car started slowing down and would not accelerate. This could have been very dangerous if I had been in the middle of 5:00 traffic. I took the next exit in front of me and pulled into a gas station. Looked under car and seen no obvious damage. Got back in and the car and put it back into drive. It would barely pull and then quick pulling all together within a few feet. The D/drive light started flashing. No warnings at all before this happened. I was 200 miles away and had to have it towed back home. Put it in the GMC shop and was told it needed a transmission.

Was driving on a highway on cruise control When it automatically disengaged by itself When I stepped on the gas the car began to shake violently, And it was not shifting years correctly. I was able to pull over and realize that the transmission Was a problem so I was able to drive manually to local dealer who diagnosed the problem as needing a new transmission. The vehicle is 2017 and has less than 63000 miles.

The contact owns a 2017 GMC Terrain. The contact stated after stopping and shifting into park(P), the ignition switch could not be turned off and the key could not be removed from the ignition switch. While the contact was inspecting the rear of the vehicle, the vehicle started to roll backwards, almost injuring the contact. The vehicle was later driven to the local dealer who diagnosed that the control shifter was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 41,000.

While driving on the highway with my child, vehicle suddenly went into reduced power mode. 5 minutes later after exiting the highway, the low oil pressure Alert came on. The vehicle was parked two minutes later then towed home. After towing it to my local certified dealership, it was determined the pcv was clogged with ice resulting in a blown rear main seal. There was a recall for a defect in earlier terrains for this same issue (See SB 14882). Currently GM will not cover repair costs under this specific recall despite this vehicle apparently having the same 2.4L Ecotek engine. Apparently this a known cold weather issue for this vehicle.

transmission jerking at low speeds no power,was told by dealer i need a new transmission i only have 60,000 miles on my 2017 terain gmc no warning indicator lights came on

AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.
