2002 Chevrolet Impala Engine

P102 MASS AIR FLOW SENSOR FAILURE, CAUSING CHECK ENGINE LIGHT TO REMAIN IN A STEADY ON CONDITION. VEHICLE WOULD FAIL EMISSIONS TEST WITH CHECK ENGINE LIGHT ON, BUT DEALER SAYS THIS CONDITION NOT COVERED BY EMISSIONS WARRANTY EVEN THOUGH THE OWNER'S MANUAL CLEARLY STATES THIS CONDITION IS A EMISSIONS SYSTEM MALFUNCTION.*AK

CATALYTIC CONVERTER CLOGGED ON 2002 VEHICLE. THE ENGINE WAS CALIBRATED TO RUN TOO LEAN MAKING THE EXHAUST GASES TOO HOT, LEADING TO PREMATURE FAILURE. NOTICED GRADUAL POWER LOSS SINCE 50,000 MILES BUT THOUGHT IT WAS AIR FILTER. ENGINE LIGHT STILL DID TURN ON. TOOK IN FOR SERVICE AND WAS TOLD IT WAS OK FOR WARRANTY. *NM

WHILE DRIVING, THE VEHICLE OVERHEATED AND SMOKE EMITTED FROM THE FRONT OF THE VEHICLE. THE CONSUMER WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE, AND DROVE IT TO THE DEALER FOR INSPECTION. THE MECHANIC DETERMINEDTHAT THE INTAKE MANIFOLD GASKTE HAD FAILED. *AK *JB

CONSUMER NOTICED THAT EVERY WEEK, HE HAD TO FILL THE COOLANT RESERVOIR. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP, AND MECHANIC DETERMINED THAT INTAKE MANIFOLD CRACKED AND COOLANT SPILLED INSIDE THE ENGINE. *AK *JB

ENGINE COOLANT HAS TURNED BROWN AND CLOGGED UP THE COOLING SYSTEM. I HAVE BEEN TOLD THIS IS A PROBLEM WITH THE TYPE OF COOLANT BEING USED IN NEW VEHICLES. I HAVE BEEN REFERED TO HAVE MY ENGINE FLUSHED AND THAT GM WILL NOT STAND UP FOR THE REPAIRS.

ENGINE STALLS, REMOTELESS KEY ENTRY DOESN'T WORK, COOLANT LEAKING. *AK

MY 2002 CHEVROLET IMPALA SUFFERED A BREAKDOWN OF THE ANTIFREEZE THAT TURNED INTO A THICK BROWN SUBSTANCE. THIS CAUSED THE VEHICLE TO OVERHEAT AND GM DID HAVE THE COOLANT FLUSHED. TWO WEEKS LATER THE LIFTER BEGAN TO RATTLE WHEN THE VEHICLE WAS FIRST STARTED. WHEN I TOOK THE VEHICLE BACK TO THE DEALER, I WAS TOLD THAT A SEAL WAS LEAKING COOLANT INTO THE OIL. I WAS ASSURRED THAT THIS WAS NOT RELATED TO THE ORIGINAL PROBLEM AND WAS NOT COVERED. THE REPAIRS WILL COST OVER 760.00. I CALLED GM CUSTOMER SERVICE AND AFTER WAITING ALL DAY, THE RESPONSE WAS THAT THE SERVICE MANAGER WAS NOT THERE, BUT THE PROBLEM COULD NOT HAVE BEEN CAUSED BY THE FIRST PROBLEM. THE COOLANT TURNED INTO A THICK BROWN GRITTY SUBSTANCE THAT WOULD HAVE BEEN LIKE SANDPAPER GOING THROUGH THE ENGINE AND THEY CLAIM THAT IT COULD NOT HAVE CAUSED THE SEAL TO FAIL. IT IS OBVIOUS THAT GENERAL MOTORS REFUSES TO STAND UP FOR OBVIOUS FAILURE AND DEFECTIVE EQUIPMENT. THEY REFUSE TO STAND UP FOR THE REPAIRS. THIS COOLANT ACCORDING TO GM IS SUPPOSED TO LAST AT LEAST 100,000 MILES AND IT DOES HOLD UP AS THEY STATE. THEY SHOULD ADMIT THE PROBLEM AND MAKE THE PROPER REPAIRS TO CUSTOMERS VEHICLES.

INTAKE MANAFOLD LEAK

INTAKE MANAFOLD LEAK

AT JUST UNDER 60,000 MILES, LOW COOLANT LIGHT COMES ON. DEALER SAYS IT'S LEAKING COOLANT AT 2 PLACES: AT LOWER INTAKE AND AT WATER PUMP. COST TO REPAIR: $600 TO $850, DEPENDING ON REPAIR FACILITY. IF THERE WAS A RECALL ON THIS, I DID NOT RECEIVE.*AK

CONSUMER SMELLED ANTI FREEZE ON THE OUTSIDE OF THE VEHICLE WHEN THE WEATHER BECAME COLD. THIS WAS DUE TO THE INTAKE MANIFOLD LEAKING ANTI FREEZE. *AK

CATALYTIC CONVERTER CLOGGED ON 2002 VEHICLE. THE ENGINE WAS CALIBRATED TO RUN TOO LEAN MAKING THE EXHAUST GASES TOO HOT, LEADING TO PREMATURE FAILURE. NOTICED GRADUAL POWER LOSS SINCE 60,000 MILES BUT THOUGHT IT WAS AIR FILTER. FINALLY, I COULD NOT GET UP TO HIGHWAY SPEEDS AT 85,000 MILES, BUT THE ENGINE LIGHT STILL DID NOT TURN ON. TOOK IN FOR SERVICE AND WAS TOLD IT WAS OUT OF WARRANTY. *LA

THE RECALL REMEDY FOR THE UPPER/LOWER INTAKE CO303-4 MANUFACTURER # IS A SHORT TERM FIX, AND IS NOT CORRECTING THE PROBLEM. *AK IF A SEALANT WAS USED TO STOP THE LEAKAGE INTO THE COOLANT SYSTEM TO THE VEHICLES MOTOR IT DID NOT FIX THE PROBLEM. ALSO IT COULD MOVE AROUND AND FLOW TO OTHER PLACES AT ANYTIME THERE WAS A TEMPERATURE CHANGE. *SCC *JB

02' CHEVROLET IMPALA. USING THREE DIFFERENT CONFINED SPACE MONITORS I HAVE FOUND CONTINUING PRESENCE OF CARBON MONOXIDE AND METHANE EMISSIONS IN THE INTERIOR/CAB OF MY VEHICLE. GM HAS INSPECTED THE VEHICLE AND HAS ALSO FOUND THE PRESENCE OF VEHICLE EMISSIONS INSIDE THE VEHICLE BUT, THEY CONTEND THE AMOUNTS ARE WITHIN EPA STANDARDS. THE PROBLEM IS ON GOING AND CONTINUES TO BE A HEALTH RISK FOR MY FAMILY. FREQUENT HEADACHES AND FATIGUE ARE OFTEN AFFECTS AFTER OPERATING THE VEHICLE. NAUSEA HAS OCCURRED AFTER LENGTHY TRIPS IN THE VEHICLE. WE HAVE RESULTED TO DRIVING WITH THE WINDOWS DOWN TO HELP ALEVE THE EFFECTS ON THE CARBON MONOXIDE, BUT THIS ISN'T THE SOLUTION. THE EMISSIONS ALSO CREATES AN ODOR THAT CLINGS TO YOUR BODY. WHAT CAN I DO? *NLM

WHILE CHECKING COOLING SYSTEM NOTICED A BUILD UP OF BROWN STUFF ON RADIATOR CAP, AND BROWN WATER AT RADIATOR TOP. COOLING LIQUID BREAKS DOWN AND CLOGS UP RADIATOR/ HEATER CORE AND ENGINE. DEALER HAS BEEN CONTACTED. PLEASE PROVIDE ANY FURTHER INFORMATION.*AK

CONSUMER STATES THAT THE VEHICLE ONLY HAS 3052 MILES ON IT AND HAS STALLED ON TWO OCCASIONS, BOTH WHILE DRIVING 45 MPH, CONSUMER HAS NOT TAKEN THE VEHICLE TO THE DEALER. *SLC

CONSUMER STATES THE WHILE DRIVING THERE IS A STRONG SMELL THAT GOES INSIDE THE CAB OF THE VEHICLE AND AT TIMES THE CONSUMER HAS TO PULL OVER BECAUSE THE CONSUMER CANNOT STAND THE SMELL. CONTACTED DEALER AND THE DEALER IS NOT WILLING TO DO ANYTHING.
