Oil consumption testing began 6/12 a week later check engine light came out. Brought my Terrain back to GMC for them to tell me that the timing chain needs to be replaced due to the oil consumption problems. Having several problems since such as jerking, and stalling that I did express to GMC over the past couple weeks, which is due to the excessive oil consumption. Still waiting to hear from the GMC to get my SUV fixed almost 40 plus days later

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.

I just hit 105K on my vehicle and the intake camshaft position timing is causing my SUV to shut off while stopped. I was pulled halfway into a major highway when the light turned green I went to take off and the engine died. I tried to see if there was maybe a recall but I did not find one for my VIN number. Anyone else's check engine light coming on and throwing this code?

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.

The contact owns a 2014 GMC Terrain. While driving up a hill, the vehicle rolled backwards. The contact had to slightly depress the accelerator pedal and the brake to keep the vehicle from rolling backwards. The dealer stated that the vehicle was designed to roll backwards. The contact stated that the clutch was not designed to hold. The manufacturer was notified. The approximate failure mileage was 15,900. Updated 07/13/16

In October 2015, I was driving on the interstate in a rural area, and accelerated to pass another vehicle. My passing speed was approximately 80 mph. I merged back into the right lane after passing, and let my foot off the gas. Cruise control was not engaged. The car continued at the passing speed, and started to increase in speed. I waited a few seconds to see what would happen before taking evasive action; as there were no other cars on the highway at this point. For 4-5 seconds this continued. I tapped the brake and no change was detected. I then tapped the accelerator pedal; and the speed disengaged. Vehicle was taken to dealer; diagnostic was run and they could not detect a problem. Dealer was of the opinion that this event had something to do with the drive train, they drove the car but were unable to duplicate the problem. This all seemed to indicate that cruise control was on; however I am sure it was not.

Driver had stopped at stop sign on the exit ramp and as she began to accelerate to crossover to appropriate lane the car stalled in the middle of the road, reduced engine light came on, and check stability light lit. This was in a very dangerous location as the side road the driver was located was at the bottom of a hill, so oncoming traffic would not have been able to stop and it would have been a T-bone hit for the driver and head on for the oncoming vehicle. The car slowly (very, very slowly) moved forward enough to finally get across street and to a safe place. Although no accidents or injuries occurred, it was by the grace of god that no traffic was coming over the hill. This had the potential and has the potential of being a deadly problem if it occurs again or if another vehicle has the same issue. Immediately had tow truck pick up car and take to GMC dealership. I am awaiting the results from the dealership. My work requires a lot of travel and now I do not feel safe in this car with this issue (which after research today seems to happen a lot in GMC vehicles. )

The drive shaft is all rusted. I told the dealer about it and they say that it is made out of steel and not to worry. I am still scared of driving it.
