2014 GMC Terrain Owner Comments

I have a 2014 GMC Terrain slt that when the lift gate is opened it goes all the way open, drops closed about 1/4 of the way and then opens fully again, then with power closes-slams shut. The first time it happened 3 days ago, it hit me in the head and knocked me to the ground. I called dealer where I purchased it from and the teck there said there were no noted problems or recalls for the "Terrain" models and I should come in and just have both the left side actuator and the right side gas strut replaced. This initially happened in my driveway with the car in park and engine off. Has also happened with the car in my driveway with engine running.

Takata recall when driving my vehicle said oil pressure was low and just shut off. Lost all oil. Mechanic said it was an issue with the PCV valve. This happened when driving and happened fast with no warning.

3 years old now and still getting around 10mpg and from the first day I got it in 2014 the drive shaft is rusted and was told by the dealer that nothing is wrong with the car. I also notice that when driving at night that the head lights are not made to see street name signs I have to use the high beams to see if I have the right street when looking for the place I have to go.

This vehicle does not have vents to circulate heat/ac in the back seat. Main issue is in the summer. My toddler son is usually sweating and in distress because he is so hot. Despite having the A/C on lowest temp, and blowing at the highest speed, it still does not circulate very well throughout the vehicle. So, I'm freezing while my son is burning up. Makes traveling difficult with an upset child. Come on, GM, smarten up. You're better than this.

Periodically auto will surge forward (without the benefit of gas pedal being depressed.) I managed to stop before there was a crash. Dealer states that no problems like this have been reported. I am certain this is a dangerous situation. The dealer has stated that there is no problem with this car. I have to trust that they did something to stop the surging (computer adjustment??)
