What owners say about the engine
Verbatim from NHTSA complaints, newest first
“Fuel system or backfire is what I believe happened to it. The vehicle is available for inspection upon request. My safety was severely put at risk because the car exploded and caught fire while I was inside the car and fire came through the dash and air conditioner slots, anything could of happened whether shrapnel or burn. this also put others at risk if my spouse was in the car with me or the apartment complex I live in could have caught fire and endangered multiple people. No the issue has not been seen or confirmed by a dealer or service center. Yes the vehicle has been inspected by state fire marshal. No there was no warning lights or problems at all. We drove the car the night before, everything was normal and nothing was showing on the dash and the next day I jumped in, put my seat belt on and started the car to make sure it was running good and it exploded and caught flames.”
“My vehicle caught on fire after I returned from it getting serviced by Pepboys in Phenix City Alabama. My car was only getting serviced for the A/C and once I returned home, my car caught on fire in our drive port.”
“I JUST PURCHASED THIS 2002 CHEVY IMPALA WHICH CAME WITH THE IMPORTANT VEHICLE SAFETY RECALL AND I WOULD NEED THE PROBLEM FIXED. NHTSA 15V-701 IM ACTUALLY NOW SCARED TO DRIVE IT/”
“SUPPOSEDLY THE COOLING SYSTEM WAS FIXED IN 2003 BUT IT STILL TELLS ME THAT MY COOLANT IS LOW AND IT LEAKS. I AM THE SECOND OWNER OF THIS CAR AND HAVE ONLY HAD IT SINCE SEPTEMBER OF 2019. ALSO THE TRANSMISSION HAS A DELAYED SHIFT FROM 1ST TO SECOND.”
“I BOUGHT A 2002 CHEVY IMPALA AND GOT IT LOOKED AT BEFORE PURCHASE THE ONLY THING THAT POPPED UP ON THE CODE READER WAS THERE IS AN ELECTRICAL PROBLEM, SOMETIMES MY SIGNAL LIGHTS WORK SOMETIMES THEY DON'T, MY SPEEDOMETER DOESN'T LIGHT UP OR ANYTHING. I THEN START TO SMELL GAS WHEN I TURN ON THE HEAT OR AIR IT'S UNBEARABLE. I THEN PROCEEDED TO CHECK FOR ANY RECALLS AND THERE ARE A FEW DEALING WITH THE ENGINE COOLING AND EXHAUST/GAS LEAK ALONG WITH ELECTRICAL ISSUES. THEY SAID THE CAR COULD CATCH ON FIRE AT ANY TIME. I HAVE TWO TODDLERS SO THERE IS NO WAY THAT THIS IS A SAFE CAR.”
