2017 GMC Terrain

1. The car started making a noise then started surging and jerking. I'm not a mechanic, so I don't know what happened but it will not crank now. Yes, someone can come inspect the vehicle, by appointment only. 2. I was afraid that the car was going to blow up or the brakes would not hold. 3. No, the problem has not been reproduced or inspected. 4. No, the vehicle or component has not been inspected. 5. NO, there were no warning lights to let me know there was a problem.

We have had many GM vehicles my husband worked at GM retired now. Our complaint is we have a GMC Denali 2017 only 79000 miles on it. All upto date changes regularly all. Other like Transmission oil changed all upkeep to date. Transmission needs rebuilt. We are in our 80’s And don’t beat up our cars. Replace or rebuild transmission 3500 to 4500 bucks. That is a lot of money for us. No longer covered. It shudders when you drive at any speed and feels so unsafe. Took it to GM garage and they couldn’t find anything wrong. No warning lights came on and we paid over 150 to have it checked out so with the shuddering getting worse and not feeling safe to drive we took it to a Transmission shop and he took it out and said the Shuddering was caused by something in the transmission. I have seen on google where GM is having a lot of problems in this area. We just need help with the repairs. Thank you. A retired GM worker Lordstown, Ohio [XXX].

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 rear main seal is out, which is causing an oil leak. The intake manifold failed because the pvc system has a clog which has caused too much pressure to build up and caused the rear main seal to blow out. (PVC pipe is freezing over in cold temperatures which causes the failure of the main seal to blow out subsequently leading to additional major issues and parts failure. This issue has occurred in an overwhelming amount of vehicles.)

2017 gmc Terrain. vin -[XXX] on 12-26-2023 milage - 80694 Catastrophic failure involving PCV Valve and blown seal that destroyed the motor. So ...why or even how are we discussing rear main Seal. This is COMPLETELY UNACCEPTA,BLE. I have 2 kids starting to drive the repair estimate is $8.000 to $10.000 INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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.
