One problem related to side/window air bag has been reported for the 2018 GMC Terrain. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2018 GMC Terrain based on all problems reported for the 2018 Terrain.
First issue with the vehicle was a separation of the dash near and around the passenger side airbag. Unknown at this time if the airbag has been compromised. I won't know until the vehicle would be involved in an accident. The second issue involves the vehicle while in park. I am able to push the vehicle and it will actually move forward. There is also a very hard shift while the vehicle is in motion. This occurs usually between 2k and 3 k rpms. The vehicle will actually jerk as it is trying to shift.
