AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.

I AM THE OWNER OF A 2017 GMC TERRAIN. YESTERDAY, I WAS INVOLVED IN A CAR ACCIDENT IN THIS VEHICLE. SOME PERSON PULLED OUT IN FRONT OF ME AND I SLAMMED ON MY BRAKES TO AVOID A CAR ACCIDENT.
