NHTSA Complaint #11221573 — 2018 BUICK ENCLAVE

DURING NORMAL COMMUTE, VEHICLE BEGAN BUCKING BADLY, WOULD NOT ACCELERATE AND BEGAN ROLLING BACKWARDS. CHECK ENGINE LIGHT ILLUMINATED. SHUT VEHICLE DOWN, RESTARTED, AND THE PROBLEM SEEMED TO CLEAR. BROUGHT VEHICLE TO DEALERSHIP, FOUND CODES P0011, P0014, P0021 AND P0024 SET. DEALERSHIP CONTACTED GM, WHO ACKNOWLEDGED THE ISSUE BUT OFFERED NO FIX. THEY ARE STILL STUDYING THE ISSUE AND HAVE NO RESOLUTION. DEALERSHIP CLEARED CODES AND RELEASED VEHICLE BACK TO US. ISSUE MAY RETURN AT ANY TIME. HOW CAN I TRUST MY FAMILY IN A VEHICLE THAT MAY SUDDENLY, WITHOUT WARNING, BEGIN BUCKING, STOP ACCELERATING AND CAUSE AN ACCIDENT? THIS IS AN UNSAFE CONDITION THAT GM NEEDS TO ADDRESS. I AM DISAPPOINTED THAT THEY HAVE NO RESOLUTION. DEALERSHIP REFERENCED BULLETIN PIP5569E, SO GM ACKNOWLEDGES THE ISSUE. I FOUND REFERENCES FROM ALMOST A YEAR AGO TO THIS ISSUE VIA GOOGLE - THAT'S VERY DISCONCERTING THAT, IN THIS TIME, GM CANNOT IDENTIFY A FIX.
