2002 Chevrolet Impala power train problems

“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.”

“TL* THE CONTACT OWNS A 2002 CHEVROLET IMPALA. WHILE DRIVING 25 MPH, THE BATTERY LIGHT ILLUMINATED. THE CONTACT DROVE TO A STOP LIGHT AND THE VEHICLE SHUT DOWN COMPLETELY. THE VEHICLE RESTARTED AFTER APPROXIMATELY 20 MINUTES. THE CONTACT REPLACED THE BATTERY, BUT THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED AND REPLACED THE CATALYTIC CONVERTER, BUT THE FAILURE RECURRED AND THE CHECK ENGINE LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO A LOCAL DEALER WHERE IT WAS DIAGNOSED AND THE AIR CONDITIONING FANS WERE REPLACED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT OFFERED NO ASSISTANCE. THE CHECK ENGINE LIGHT REMAINED ILLUMINATED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 79,000.”

“MASS AIR FLOW SENSOR MAF MALFUNCTION IF CORRODED OR DIRTY WILL CAUSE THE ENGINE TO STALL. ENGINE STALLING CAUSES LOSS OF POWER STEERING AND LOSS OF BRAKES. DISASTEROUS AT FREEWAY SPEEDS, INTERSECTIONS, OR IN ANY SITUATION REQUIRING STEERING OR BRAKING. THIS CAR MAF FAILED GOING DOWN A STEEP MOUNTAIN ROAD, THE DRIVER WAS ABLE TO STOP THE VEHICLE USING MANUAL BRAKE AND HAD IT TOWED TO THE DEALER FOR REPAIR. *TR”

“TRAVELING ON A STRAIGHT RESIDENTIAL STREET AFTER CAR HAD BEEN DRIVEN ABOUT 10 MILES AND WAS AT OPERATING TEMPERATURE, I HEARD A SHORT "CHIRP" SOUND FROM THE FRONT PASSENGER SIDE OF THE CAR AT WHICH TIME THE ENGINE STOPPED RUNNING. STEERING BECAME VERY DIFFICULT AND THE BRAKE PEDAL REQUIRED SUBSTANTIAL FORCE TO STOP THE CAR. I WAS ABLE TO BRING THE CAR TO A STOP AND PUT THE CAR IN PARK. THE ENGINE RESTARTED IMMEDIATELY WITH NO PROBLEM. I WAS NOT MOVING OR TOUCHING THE KEY AT THE TIME THAT THE ENGINE TURNED OFF. I HAVE OWNED THE CAR SINCE IT WAS NEW IN NOVEMBER 2001 AND THIS IS THE FIRST TIME THAT I HAVE EXPERIENCED THIS PROBLEM. I HAVE DRIVEN THE CAR ABOUT 20 MILES SINCE THIS INCIDENT AND IT HAS NOT RECURRED AS OF YET. *TR”

“THE CAR WAS CONSTANTLY STALLING IN LOW SPEED OR STARTING FROM A STOP IN D DRIVE. THE TRANSMISSION WAS NOT SHIFTING PROPERLY. CAR HAD STALLED A FEW TIMES IN TRAFFIC, BECOMING A HAZARDOUS SITUATION. CAR WAS OVERHEATING. CAR HAD BEEN SERVICED A WEEK AGO AT AAA REPAIR CENTER, EATONTOWN, NJ FOR OIL LEAK FROM GASKET OF THE MANIFOLD. *TR”

“SHORTLY AFTER PURCHASING THIS VEHICLE, I PARKED AND WHEN I TRIED TO START IT WOULD NOT START. AFTER WAITING ABOUT 20 MINUTES IT DID START. I TOOK IT TO THE DEALER AND WAS TOLD IT WAS A SENSOR WHICH THEY REPLACED. DID NOT STOP THE PROBLEM, CONTINUES TO DO IT TODAY. NOW AT ABOUT 8500 MILES A MESSAGE COMES UP TO SERVICE TRACT SYSTEM. AM TOLD IT IS A SENSOR IN THE HUB AND THE ENTIRE HUB WILL HAVE TO BE REPLACED AT A COST OF ABOUT $750 PER HUB FOR THE FRONT AND SLIGHTLY MORE IF IT IS THE REAR HUB. AFTER READING ON THE INTERNET OF THIS SAME PROBLEM PEOPLE ARE HAVING, I REALIZE I AM NOT THE ONLY ONE HAVING THIS PROBLEM AND IT SEEMS ALL THESE FIXES DO NOT STOP THE PROBLEM. I PURCHASE THE CAR NEW AND LOVE THE RIDE AND PERFORMANCE I GET FROM THIS CAR BUT AM NOT ABLE AT THE TIME TO PAY FOR EXPENSES OF THIS MAGNITUDE. HAVE CONSIDERED TRADING BUT DO NOT WANT TO SADDLE SOMEONE ELSE WITH THIS PROBLEM. WOULD NOT MIND THE REPAIRS IF IT WAS GOING TO FIX THE PROBLEM, BUT SEEMS AS IF THIS IS A PROBLEM THAT CANNOT BE FIXED. HELP *TR”
