I HAVE A 2004 CHEVROLET IMPALA LS WITH AN AUTOMATIC TRANSMISSION 3.2 V6. THE SPEEDOMETER WILL STAY ON 70MPH AT REST OR MORE THEN GO OVER A 120MPH WHEN TRAVELING. ONCE IN AWHILE IT MAY RESUME BACK TO NORMAL. IT IS A HUGE PROBLEM IN NOT LETTING YOU KNOW EXACTLY WHAT RATE OF SPEED YOU ARE TRAVELING. *TR

NOW AT 117,000 KMS. OR PAST MY FIVE YEAR WARRANTY. SINCE 88,000KMS. HAVE COMPLAINED SEVERAL TIMES ABOUT TEMP GAUGE VERY OUT OF WHACK ON HIGHWAY TRIPS, LEAD ME TO BELIEVE SEVERELY OVERHEATED, BUT NO MESSAGE FROM CAR, JUST GAUGE GOING ALMOST 90 DEGREES PAST "DANGER POINT " OF GAUGE. IN LAST TWO YEARS TEMP GAUGE REPLACED THREE TIMES. OBVIOUSLY NOT THE PROBLEM. RETURNS TO NORMAL FUNCTION IN CITY OR SHORT HAUL DRIVING. STOP FREQUENTLY, AND UNDER HOOD CHECK SHOWS NO SIGNS OF OVERHEATING. CONCLUSION- ELECTRICAL, SENSOR, PROBLEM AND DEALER KEEPS COMING UP WITH COSTLY NEW EQUIPMENT FIXES WHICH DO NOT WORK. NOW THEY WANT TO BLAME A WATER PUMP LEAK AND GASKETS, ALTHOUGH RESERVOIR CAREFULLY WATCHED BY ME. NO LEAKS THERE. HAVE NEVER HAD TO ADD FLUID, ALTHOUGH I KEEP IT ALWAYS IN CAR-THAT IS THE DEXCOOL-WATER MIX. NEVER DOWN LOWER THAN RECOMMENDED, AND THE DEALER WANTS TO GIVE ME A NEW WATER PUMP AND TAKE 1000-1200 OUT OF MY POCKET. THEY HAVE NEVER MENTIONED THE TEMP SENSOR, OR ANY OTHER FIX. TRAVEL ON MOUNTAIN HIGHWAYS 3 TIMES PER YEAR, GAUGE NOW GONE WAY OVER THE TOP 6-8 TIMES. ALWAYS STOP. NO SIGN EVER OF HOSE, RADIATOR, WATER, LOWERED RESERVOIR, OR COMPUTER MESSAGES AS PER MANUAL. HAVE READ OF NUMEROUS SIMILAR PROBLEMS OF THIS MAKE AND MODEL, THE 04 CHEVY IMPALA LS, ALWAYS GAUGES. IN MY CASE I WILL NOT APPROVE ANOTHER TEMP GAUGE "FIX" AND NOW SPEEDOMETER IS ACTING UP AS WELL, JUST LIKE OTHER DRIVERS REPORTED. *TR

15V701000 · Engine And Engine Cooling:engine; Engine And Engine Cooling:exhaust System:manifold/header/muffler/tail Pipe

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. The recall began on February 19, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020, Buick customer service at 1-800-521-7300, Oldsmobile customer service at 1-800-442-6537 and Pontiac customer service at 1-800-458-8006.
