CHEVY IMPALA 2004 LS- THE VEHICLE IS STOPPING COMPLETELY WHILE DRIVING OR SITTING AT INTERSECTION. THERE IS NO WARNING, NO MESSAGE, IT JUST DIES. THE STEERING GOES WHEN THIS HAPPENS SO I CANNOT EVEN GET OFF THE ROAD. THEN THERE ARE TIMES THAT THE CAR WILL NOT START AT ALL AND I HAVE BEEN STRANDED. EVENTUALLY AFTER ABOUT 20 MINUTES THE CAR WILL START- I HAVE ALREADY REPLACED THE STARTER BUT THE PROBLEM STILL EXISTS. I HAVE HAD THE CAR CHECKED OUT AT 2 DIFFERENT SHOPS (FIRESTONE) AND THEY CANNOT FIND THE PROBLEM. THERE ARE NO CODES COMING UP. THEY ARE COMPLETELY PERPLEXED. CHEVY STATES THEIR MECHANICS ARE BETTER. ALSO THE CLUSTER PANEL IS GONE AND CHEVY IS AWARE OF THE PROBLEM BUT THEY ONLY RECALLED CERTAIN MODELS AND DID NOT INCLUDE THE IMPALAS. I HAVE 2 ESTIMATES REGARDING FIXING THIS PROBLEM BUT THE QUOTES ARE $500.00. I DO NOT FEEL THAT I SHOULD HAVE TO PAY FOR THIS WHEN CHEVY KNEW THEY HAD THIS PROBLEM WITH CLUSTER PANELS AND OMITTED THE IMPALAS IN THEIR RECALL. SO, TO RECAP: THE CAR DIES IN TRAFFIC (ALMOST HIT TWICE), I DO NOT KNOW HOW MUCH GAS I HAVE, HOW FAST I AM GOING, OR IF THE CAR IS OVERHEATING. IN DEALING WITH CHEVY I WAS TOLD TO TAKE THE CAR TO A CHEVY DEALERSHIP. THEY GAVE ME A PLACE THAT IS 2 1/2 HOURS HOUSE AWAY FROM MY HOME. I WAS ALSO TOLD THAT I WOULD HAVE THE HONOR OF PAYING FOR THE DIAGNOSTICS. IN RESEARCHING THIS PROBLEM, I HAVE PULLED UP SEVERAL COMPLAINTS FROM OTHER CHEVY IMPALA 2004 OWNERS THAT ARE EXPERIENCING THE SAME MULTIPLE PROBLEMS. I ALSO NOTICED THAT MOST OF THE COMPLAINTS ARE STATING THAT THE SAME ISSUES OCCURRED AT APPROX. THE SAME MILEAGE AS MINE. I HAVE DISCUSSED THIS WITH CHEVY CUSTOMER SERVICE AND BASICALLY THAT WAS IGNORED. THIS CAR IS HAZARDOUS TO DRIVE AND POTENTIALLY WILL CAUSE BODILY HARM. DEALING WITH CHEVY IS POINTLESS. ALL THEY CAN THINK OF IS HOW MUCH MONEY THEIR DEFECTS WILL BRING IN. *TR

JUST LIKE THAT. I WAS DRIVING ON THE HIGH WAY AND APPROACHED AN ACCIDENT. AFTER COMING TO A COMPLETE STOP TRIED TO PICK SPEED BACK UP AND IT WOULDN'T GO ANYMORE THAN 15 MPH. I PULLED OFF TO A REST AREA, SAT THERE FOR 30MINS. REVERSED OUT OF THE PARKING LOT, PUT IT IN DRIVE, IT WOULDN'T BUDGE... NOT TO MENTION A MONTH AFTER BUYING THE CAR. THE TURN SIGNALS,, BRAKE LIGHTS, CRUISE CONTROL, FLASHERS ALL WORKED WHEN THEY WANTED TOO AND NOT WHEN I NEEDED IT TOO.
