2018 GMC Terrain

Hello. As I come to a complete stop the car will go into auto-stop. After releasing the brake pedal the car will jerk forward . As I press the gas pedal the car Jerks and shakes . The rpm jumps way up and the mph say low.. there's been times I try to accelerate and the car with jerk and put itself into park.. in the middle of traffic.. heart pounding to say the lease. I also notice theres alot of black liquid dripping for the front right side under the front bumper. There were no problems with the car or lamp indicating there were before this. I went to where I brought the car and they told me my warranty expired and that I will need to pay $265 just to diagnose the issue. I didnt have that money. I do have a car code reader and I did my best to find a solution. Codes P0700, P171D, And P187D all appear on my device. I then looked up recalls and my VIN wasn't confirmed.. but I am certain it is the same issue . You do have a open recall for this very particular issue for my particular model . I love my car and GMC. Please remedy this situation and have me driving safely and free minded again and soon ! Please reach back with any feedback as soon as possible. Thanks !

When driving the car at low speeds, or right after having been stopped for a few moments. Upon, acceleration, the car will sometimes go into a limp mode. On the DIC, will be displayed a warning about how the car will have the speed reduced after 175 miles and to check the emissions system. The speed has already been reduced at that point. Also displayed maybe a warning about how the power has been reduced. USUALLY, if I turn off the car and wait about a minute, I can restart the car and drive at a normal highway speed again. But not always. The warning on the DIC, will usually turn off if the car does return to normal speeds after about 5 - 10 miles. However, the check engine light may still stay on for several days. This problem can be a daily occurrence. I've had the car in the shop several times, and they have been unable to fix the problem. The car can be unpredictably unsafe, when speed is instantly reduced to 30 mph!

I have a 2018 GMC TERRAIN which I bought brand new from General Motors. In May 2022, the vehicle started jerking/hoping and trying to stall when the speed gets to 55 miles per hour or higher. I have taken it to the dealership on three different occasions for repair and I still have this issue. General Motors engineers were involved in every step of the repairs. They just do not know what is going on with the car or fix it and they are too stubborn. The dealership told me today that they cannot do anything else to the car. They also said they had a code from the engine last week and General Motors said they do not know what that code means. They are forcing me to accept/drive the car in this unsafe condition. I have contacted them multiple times and they do not care.

THE SERVICE STABILITRAK LIGHT CONTINUES TO COME ON. WHEN IT DOES, ALMOST ALL OF THE LIGHTS ON THE DASH LIGHT UP AND THE CAR PUTS ITSELF IN NEUTRAL AND SHUTS OFF. THIS HAS HAPPENED 5 TIMES IN THE PAST TWO WEEKS. TWICE WITH MY [XXX] IN THE CAR. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). THE CAR WAS PURCHASED 12/23/2020 AND IT FIRST SHUT OFF WITH THE SERVICE STABILITRAK WARNING 12/31/2020. I'VE TAKEN IT TO THE DEALERSHIP FOR REPAIR. THEY REPLACED THE FRONT RIGHT WHEEL SENSOR TODAY AND IMMEDIATELY AFTER LEAVING THEIR LOT, IT SHUT OFF TWICE. I DID A SEARCH ON THE VIN AND FOUND THAT THIS VEHICLE HAD ISSUES AT 11K MILES AND 27K MILES. NOW AGAIN AT 55K MILES. THE CAR JUST SHUTS ITSELF OFF WHILE DRIVING. FIRST TIME IT HAPPENED, I WAS ROUNDING A CORNER IN HIGH TRAFFIC AND IN MID TURN, THE CAR SHUT OFF. I WAS ALMOST HIT BY SEVERAL CARS. THIS VEHICLE IS DANGEROUS. IT HAPPENED ONCE WHILE ON THE HIGHWAY WITH MY 15 MONTH OLD IN THE CAR AND TODAY IT HAPPENED TWICE WITH HER IN THE CAR.

PARKED IT AGAIN AND TURNED IT OFF. CALLED DEALERSHIP, WHO CALLED A TOW SERVICE TO TOW IT TO THEM. ATTEMPTED TO SHOW TOW GUY THE ISSUE AT HIS REQUEST, UPON HIS ARRIVAL, PUT IT IN REVERSE AND IT REVVED UP BRIEFLY THEN JERKED INTO REVERSE.
