TL*THE CONTACT OWNS A 2004 CHEVROLET IMPALA. OCCASIONALLY, WHEN THE CONTACT ATTEMPTED TO START THE VEHICLE, THERE WAS A DELAYED CRANK. THE VEHICLE TAKES SEVERAL HOURS TO START SOMETIMES. PRIOR TO THE FAILURE, ALL OF THE WARNING LIGHTS ILLUMINATED ON THE INSTRUMENT CONTROL PANEL. THE VEHICLE LOST ALL POWER AS IF THE BATTERY FAILED; HOWEVER, THE EXTERIOR LIGHTING WAS STILL OPERATIVE. THE CONTACT ALSO HEARD A DULL HUMMING NOISE. THE CONTACT WAS ADVISED BY ANOTHER CONSUMER WHO WAS EXPERIENCING SIMILAR FAILURES THAT THE COMPUTER CHIP WAS NOT RECOGNIZING THE KEY. SHE TOOK THE VEHICLE TO AN AUTHORIZED DEALER, BUT THEY COULD NOT DUPLICATE THE FAILURE OR PROVIDE A SUFFICIENT REPAIR. THE DEALER ALSO STATED THAT THERE COULD BE SEVERAL DEFECTS WITH THE ELECTRICAL SYSTEM: IGNITION MODULE; HOWEVER, THEY WERE AFRAID TO MAKE REPAIRS BECAUSE THEY DID NOT KNOW IF EITHER OF THE REMEDIES WOULD RESOLVE THE ISSUE. THE STARTER AND BATTERY WERE REPLACED, BUT IMMEDIATELY AFTER THE REPAIR THE VEHICLE FAILED. THE FAILURE AND CURRENT MILEAGES WERE 52,000.

MY IMPALA 2004 HAS ABOUT 41,000 MILES ON IT. THE TEMPERATURE GAUGE NEEDLE WENT RIGHT OVER TO HOT, I IMMEDIATELY BROUGHT MY VEHICLE IN AND FOR A HALF AN HOUR HAD IT ON A MACHINE TO LET ME KNOW IF IT WAS SERIOUS. THE RESULT FROM THIS TEST WAS, I COULD GET AWAY WITH DRIVING THE VEHICLE AS IS AND JUST WATCH MY VEHICLE FOR ANY SIGNS OF OVERHEATING OR GET THE PROBLEM FIXED. A MONTH OR SO LATER MY SECURITY LIGHT CAME ON AND AFTER SHUTTING THE VEHICLE OFF IT WAS FINE. THIS HAS HAPPENED ON A NUMBER OF OCCASIONS NOW AND I CALLED CHEVROLET AND THE FIRST MECHANIC OF COURSE TOLD ME IT WAS SERIOUS AND BRING IT RIGHT IN AND THE SECOND CHEVROLET MECHANIC TOLD ME THAT IT WAS OKAY TO DRIVE, JUST TURN THE VEHICLE OFF AND WAIT ABOUT 20 MIN AND THE VEHICLE SHOULD START. WAS INFORMED THAT IT WILL BE EXPENSIVE TO GET THESE ELECTRICAL PROBLEMS REPAIRED. AFTER READING THIS SIGHT AND SPEAKING WITH OTHER IMPALA OWNERS I REALIZED THAT MY VEHICLE IS NOT THE ONLY ONE HAVING THIS TYPE OF PROBLEMS AND PERHAPS CHEVROLET SHOULD LOOK INTO THIS AND DO THE RIGHT THING AND ISSUE A RECALL. *TR

OWNERS OF THESE CARS SHOULD NOT HAVE TO PAY FOR THE FIX BECAUSE THEY DID NOTHING WRONG AND ITS A CRUCIAL PART OF THE CAR. GM SCREWED UP AND SHOULD RECALL BECAUSE IT IS DANGEROUS WHEN PEOPLE DRIVE WITHOUT THE SPEEDOMETER BECAUSE THEY DON'T HAVE THE MONEY OR DON'T WANT TO WASTE IT. *TR

THE SPEEDOMETER STARTED GETTING STUCK ABOUT SIX MONTHS AGO. FOR ABOUT EIGHT MONTHS I HAVE NOTICED THAT WHEN I TURN THE STEERING WHEEL I HEAR A NOISE IN THE FRONT OF THE CAR, LIKE A KNOCK OR SOMETHING. ALSO WITHIN THE LAST COUPLE OF MONTHS I HAVE ALSO SMELLED GAS WHEN I FIRST START THE CAR , MY HUSBAND COULD NOT SEE ANY LEAKAGE OR ANYTHING UNTIL LAST WEEK. IT WAS LEAKING FROM THE FUEL REGULATOR VALVE. NOW THE TRANSMISSION IS STARTING TO SHIFT HARD SOMETIMES. I HAVEN'T HAD THE MONEY TO GET IT ALL CHECKED OUT BY THE MANUFACTURER BUT I WAS WONDERING IF THERE HAVE BEEN ANY COMPLAINTS ON ANY OF THESE THINGS. ALSO I CAN HEAR A WHISTLING SOUND WHEN I PRESS THE ACCELERATOR. AND MY HUSBAND JUST INFORMED ME THAT HE BOUGHT A REGULATOR VALVE FOR IT AND SOME O RINGS BECAUSE SOMETHING IS LEAKING ANTIFREEZE SLIGHTLY. CAN YOU HELP PLEASE!!!!!!!! *TR
