Vehicle purchase from coulter cadillac tempe az - 9/1/2018. this problem has occured 3 times. dealer acknowledges "we put you in a bad car". problem: vehicle while in motion (street/intersection/highway), will just "shut down" and move in "limp mode" fashion. the engine and stability lights will appear on the dashboard and on the most recent event, all the gauges on the dashboard shut down. after the shut down,1 & 2 gears are no longer available. in order to move the vehicle, the vehicle needs to reach a speed between 20 / 30 miles an hour in order for the 3rd gear to engage. the last time this situation happened was on the freeway @ 65 mph. i was in the hov lane with my 3.5 year old grandson and my wife. all the traffic @ 4:45 pm on the northbound lane of the az 17 highway came to a stop because of the rippling effect this problem caused. fortunate for us, other drivers allowed to us traverse to the off ramp. the dealer indicated the problem was the battery that brought the car to a stop and "limp mode". there were no battery warning lights visible on the dashboard telling me the battery was in danger of failing as noted in the owner's manual. all 3 times this has happened, the dealer has provided 3 different solutions for the same problem. i have seen on this web site no less than 15 complaints raising this problem to the nhtsa attention. someone is going to get hurt because of this problem coulter/gmc and the nhtsa need to take action to remove/resolve this problem. see attached exhibit t / u / o.
The engine light came on after an 3 days after oil change and begin to cut off when i would accelerate. i took it to carmax and they said it was a faulty sensor which was covered by the powertrain warranty. carmax suggested i take the car to a gmc dealer for repair. i took the car to the gmc dealer, they repaired it and 1 1/2 weeks later the engine light came on and the car was cutting off again. i went to the gmc dealer a second time and they said, "they could not duplicate my concerns, there was no problem with the car, the engine light is not on and the car was driven for 10 minutes without any issues". after driving the car for 5 days, the engine light is on again and the car is stalling. i have to accelerate over 10 - 20 miles for the car to stay on. i know that something is wrong, i have been afraid to drive because with the car cuts off on me and no one has given a reason as to why. i do not want to get hit from behind. i drive the highway with a small child daily. i am concern that this issue is not being taken seriously. something is wrong with the car!!!
Leaving my parking spot after going out to eat i went in reverse and the vehicle stalled at about 5mph, turned the car completely off and then turned back on. put it in drive and just as i started to accelerate it stalled. this happened 10-12 times while i was trying to leave the parking lot. vehicle stalled while leaving car wash as i was excelleratig our. vehicle stalled as i was leaving a complete stop from a stop sign on a city street. something is wrong with the engine stalling while starting to accelerate. 43,000 miles from first occurrence currently at 43,300 still happening on a regular basis.
Third time while driving on city streets the car begins to shake and stall. i pull over or stay in place as the car proceeds to turn off. the service stability traction and engine lights light up and the car dies. each time i am able to turn the car back on within a few minutes.
Tl* the contact owns a 2015 gmc terrain. the contact heard an abnormal noise coming from the vehicle. the dealer diagnosed that the water pump, timing belt, gasket kit, and chain links for the timing belt failed and needed to be replaced. the vehicle was repaired. after being serviced, the vehicle later began to lunge forward and the gears attempted to shift. the vehicle was taken back to the dealer where it was diagnosed that the transmission was slipping. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was approximately 24,461.
Engine keeps shutting off while driving; would have to guide the car off the road and restart. radio shuts off; all electrical systems shut off and car would have to be restarted. this has been happening after the car was purchased sporadically since last year. the vehicle was turned in for service on the issue, however i was informed that they found nothing wrong. just this past week till now, the cars engine and electrical system starting shutting down again while driving or while in parking mode at least more than 6 times.
I've attached my final repair notice to gm and it has all of the details. i have since taken my car back to the dealership to have the final repair done. they still say nothing is wrong with it. i am terrified to drive my car. i asked gm to take the car back and they say they are not willing to do anything at all to help me. the transmission is jerky and the brakes barely work. please investigate. its like gm would like to wait until there is a huge accident and loss of life before doing anything.
While switching lanes in traffic ( around 15 mph), the vehicle shut off (including radio gauges and engine). put on hazards, switched from drive to park, and restarted the car. *tr
2015 gmc terrain. consumer writes in regards to sudden loss of engine power, accelerator pedal and throttle failures. *smd the consumer stated when she tried to accelerate, the vehicle barely moved. the consumer turned off the vehicle and re-started it, with the same results. the engine would just idle as if the accelerator pedal was disconnected. *jb
