NHTSA Complaint #10937100 — 2014 CHEVROLET IMPALA

ON 12/21/16 WHILE MERGING ONTO INTERSTATE 10 IN TUCSON, AZ, THE VEHICLE WAS GOING APPROXIMATELY 65 MPH WHEN A "ENGINE POWER REDUCED" SIGN POPPED UP, THE VEHICLE SLOWED DOWN TO 30 MPH WITHOUT WARNING AND SHIFTING DOWN THROUGH ALL GEARS NEARLY RED LINING THE RPMS AND CAUSING AN REAR-END COLLISION. WAS ABLE TO MOVE THE VEHICLE OFF THE FREEWAY AND TOOK IT INTO LOCAL AUTO-ZONE FOR TESTING. THE TEST CAME BACK AS A "THROTTLE SENSOR MALFUNCTION". THE VEHICLE NOW DOESN'T FEEL SAFE TO DRIVE, AND WILL NOT ACCELERATE OVER 45 MPH WITHOUT SHAKING AND FEELING LIKE THE TRANSMISSION IS GOING TO GIVE OUT. CALLED THE LOCAL CHEVY DEALERSHIP AND WAS TOLD THE COST WAS GOING TO VARY BETWEEN $400-1,000 WITH A $100 TEST FEE UP FRONT. I'VE ALSO READ NUMEROUS SIMILAR ISSUES ONLINE FROM PEOPLE DRIVING CHEVROLET IMPALA FROM 2006-2016. THE CAR FEEL VERY UNSAFE TO DRIVE AND I FEEL IT COULD BE A DEATH TRAP AS THERE IS NO CONTROL OVER WHEN THE VEHICLE WILL CHOOSE TO DECELERATE WITHOUT WARNING. THERE HAS BEEN NO MECHANICAL ISSUES BEFORE THIS INCIDENT, AND THE VEHICLE HAS BEEN THROUGH NUMEROUS MECHANICAL MAINTENANCE UP-KEEPS THAT WERE RECOMMENDED BY SERVICE MANAGERS. *TR
