I SERIOUSLY THOUGHT I WAS THE ONLY ONE HAVING THESE PROBLEMS. I BOUGHT A 2004 CHEVROLET IMPALA IN AUG 07. THE PROBLEMS STARTED ONLY A MONTH AFTER I BOUGHT THE CAR. FIRST THE TEMP GAUGE WOULD REGISTER ALL THE WAY UP TO 260. AFTER CHECKING TO MAKE SURE THE CAR WAS NOT RUNNING HOT, I STARTED CALLING DEALERS TO TRY TO FIGURE OUT WHAT THE PROBLEM WAS. I WAS INFORMED BY A SEVERAL DEALERSHIPS THEY HAVE SEEN SEVERAL PROBLEMS WITH THE INSTRUMENT PANEL AND THEY CONTINUED TELLING HOW MUCH IT WOULD COST TO REPLACE IT. WELL ONLY A COUPLE WEEKS LATER THE SPEEDOMETER STARTED THE SAME THING. IT WOULD STICK AND NOT REGISTER RIGHT. THE PROBLEM IS STILL CONTINUING CAUSE I CAN'T AFFORD TO FIX IT. I CONTINUED MY REGULAR MAINTENANCE ON THE CAR AND DURING AND OIL CHANGE I WAS INFORMED THE TRANSMISSION FLUID NEEDED TO CHANGED, SO I MADE THE APPOINTMENT TO HAVE IT CHANGED ON SATURDAY. ONLY A COUPLE OF HOURS AFTER HAVING IT CHANGED WE WENT TO BACK UP AND THE TRANSMISSION SLIPPED. THIS HAD NEVER HAPPENED BEFORE SO WE THOUGHT IT JUST MIGHT BE LOW ON FLUID. AFTER CHECKING THE FLUID LEVEL WAS FINE BUT THE PROBLEMS CONTINUED. NOW IT SLIPS WHEN I PUT IT IN DRIVE TO TAKE OFF AND YOU CAN HEAR THE TRANSMISSION WHINING WHILE BEING DRIVEN. AS OF NOW IT STILL SLIPS, SOMETIMES, ANDS WHINES, AND OF COURSE THE INSTRUMENT PANEL IS STILL MESSED UP BECAUSE I CANNOT AFFORD TO HAVE IT FIXED. I HAVE SPOKEN TO SEVERAL PEOPLE THAT OWN IMPALAS AND I HAVE COME TO FIND OUT THEY ARE HAVING THE SAME PROBLEMS I AM HAVING. YOU WOULD THINK BY NOW THAT GM WOULD REALIZE THERE IS A PROBLEM AND THEY ARE NOT JUST ISOLATED INCIDENTS. *TR

I WAS DRIVING AND NOTICED THAT MY SPEEDOMETER WAS SITTING ON ZERO. MONTHS LATER I NOTICED THAT MY GAS GAUGE STARTED GOING HAYWIRE. ONE MINUTE IT WAS FULL THE NEXT IT WAS 1/2 FULL AND I HAD ONLY GONE 20 MILES DOWN THE ROAD. THEN MY DAD USED MY CAR ONE DAY AND TOLD ME THAT THE OIL PRESSURE GAUGE WAS WRONG AS WELL. I HAVE NOT HAD THE MONEY TO FIX THIS PROBLEM AND THE ONLY WAY I KNOW I NEED GAS IS WHEN THE LOW FUEL MESSAGE COMES UP IN THE MESSAGE CENTER. I HAVE RECEIVED ABOUT 4 SPEEDING TICKETS JUST IN THE LAST YEAR AND WOULD HAVE RECEIVED MORE IF I HAD NOT KNOWN THE OFFICER OR TOLD THEM THE PROBLEM AND BEGGED THAT THEY LET ME OFF WITH A WARNING. *TR

THE SPEEDOMETER ON MY 2004 CHEVROLET IMPALA GOES CRAZY. AFTER IT HAS BEEN RUN FOR MORE THAN AN HOUR IT WILL STICK ON YOUR HIGHEST SPEED, NOT DROP BACK TO ZERO AND SHOW A SPEED FROM 10 TO 100 MILE MORE THAN THE ACTUAL SPEED. VERY UNSAFE, WHEN YOU DO NOT KNOW HOW FAST YOU ARE GOING. *TR

IT TAKES A COUPLE DAYS TO RESET ITSELF, AND THEN THE PROBLEM STARTS ALL OVER AGAIN. HUGE PROBLEM BECAUSE I DON'T KNOW HOW FAST I'M GOING. OF COURSE IT'S OUT OF WARRANTY AND COSTS OVER $500 TO REPAIR, BUT DOING SOME RESEARCH IT SOUNDS LIKE IT IS A MALFUNCTIONING PART ON ALMOST ALL 2004 IMPALAS, WHICH I BELIEVE SHOULD LEAD TO A RECALL, NOT MONEY OUT OF EVERY OWNERS POCKET. SEEMS LIKE A HUGE SAFETY ISSUE TO ME. *TR

Oct 26, 2015

General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold.

Consequence & remedy

Consequence: Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.

Remedy: The remedy applied under recalls 08V-118, 09V-116, and 15V-201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engine’s front valve cover and gasket. Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number.
