NHTSA Complaint #11413574 — 2021 GMC ACADIA

WIFE WAS DRIVING SOUTHBOUND ON US287 BETWEEN VERNON, TX AND WICHITA FALLS, TX IN A 75MPH SPEED ZONE. VEHICLE ABRUPTLY AND FOR NO APPARENT REASON SLOWED AS IF THE BRAKES HAD BEEN APPLIED WITH SUFFICIENT FORCE TO CAUSE HER TO BEND FORWARD AT THE WAIST. SUBSEQUENTLY, THE VEHICLE SPEED BECAME ERRATIC AND SHE SLOWED TO 25 WHILE MOVING ONTO THE SHOULDER. COULD EASILY HAVE CAUSED A FATAL ACCIDENT HAD TRAFFIC NOT BEEN UNUSUALLY LIGHT. I AM ENCLOSING GM SERVICE BULLETIN ISSUED IN JULY OF 2020 (I FOUND IT POSTED ON THE NHTSA WEB SITE) REGARDING THE TRANSMISSION USED IN THIS CAR. A SAFETY RECALL SHOULD BE IMMEDIATELY ISSUED .GM NHTSA SHOULD HAVE REQUIRED GM TO NOTIFY BUYERS OF THIS CONDITION PRIOR TO PURCHASE WHEN THE INHERENT POTENTIAL DEFECT FIRST BECAME APPARENT. WE BOUGHT THE VEHICLE NEW IN QUESTION ON 2 FEB 21 AND IT HAD BEEN DRIVEN JUST 4,063 MILES AT TIME OF INCIDENT.
