NHTSA Complaint #11207418 — 2008 CHEVROLET IMPALA

DRIVING ON HIGHWAY @ 60 MPH WHEN ENGINE DIES WITH NO WARNING. DASH SHOWS FOLLOWING MESSAGES: "ENGINE POWER REDUCED" "SERIVCE TRACTION CONTROL" "SERVICE STABILITRAX" POWER STEERING AND POWER BRAKES STOP WORKING. WHEN CAR KEY IS TURNED OFF AND CHECK ENGINE CODES ARE CLEARED, THE CAR STARTS UP FINE AND CONTINUES TO RUN SMOOTHLY. LUCKILY I WAS ABLE TO SAFELY STOP THE CAR (ALBEIT ON THE MIDDLE OF A MAJOR HIGHWAY), TURN IT OFF, CLEAR THE CODES, AND START IT BACK UP TO GET OUT OF THE WAY. SAME PROBLEM HAPPENED IN JANUARY 2018. AFTER THIS I TOOK IT TO A CHEVY DEALER. THEY SAID CAR WAS COVERED UNDER "WARRANTY" FOR THIS PROBLEM AND THEY REPLACED THE THROTTLE BODY. ONE MONTH LATER SAME PROBLEM KEEPS OCCURRING. CAR RUNS FINE BUT THESE MESSAGES APPEAR ABOUT ONCE A MONTH. TYPICALLY THE ENGINE STAYS ON AND IS ONLY LIMITED IN POWER. HOWEVER, OCCASIONALLY THE CAR WILL DIE COMPLETELY WITHOUT WARNING, EVEN ON THE HIGHWAY. HAD CAR BROUGHT TO CHEVY DEALER. THEY SAID THEY CAN NOT FIX THE PROBLEM UNLESS IT IS CURRENTLY OCCURRING WITH THE CAR. THEY RECOMMENDED I TAKE THE CAR AND BRING IT BACK TO THEM WHEN THE PROBLEM HAPPENS AGAIN. HOWEVER, I DO NOT FEEL SAFE DRIVING THIS CAR KNOWING THE ENGINE COULD JUST SHUT DOWN AT ANY MOMENT AND THE CHEVY SPECIALIST THEMSELVES DO NOT SEEM TO EVEN HAVE A CLUE ABOUT WHAT COULD BE CAUSING THIS.
