2004 CHEVY IMPALA THE MANUFACTURER INSTALLED PASSLOCK SYSTEM CONTINUOUSLY LOCKS THE CAR FROM BEING CRANKED. EVERYTHING WILL OPERATE PROPERLY EXCEPT BEING ABLE TO CRANK THE VEHICLE. THIS HAPPENS ABOUT EVERY 20 TIMES YOU CRANK THE VEHICLE. YOU HAVE TO WAIT AT LEAST 10 MINUTES BEFORE THE VEHICLE WILL CRANK. IF YOU TAKE THE KEY OUT OF THE IGNITION DURING THAT TIME IT IS LIKELY THAT THE SYSTEM WILL NOT RESET ITSELF, THUS STARTING THE PROCESS OVER AGAIN. I CONTACTED 2 GM DEALERSHIPS WHO SAID THEY COULD NOT FIX IT. HAD ANOTHER MECHANIC LOOK INTO IT AND HE TRIED REPLACING THE IGNITION BUT THAT DIDN'T WORK EITHER. THAT COST NEARLY $800.00. NOW I SIT IN THE BLAZING SUN OR FREEZING COLD OR RAIN AND WAIT FOR THE CAR TO FINALLY START. GM NEEDS TO FIX THIS FOR ALL OWNERS AT NO CHARGE. SADLY FOR THEM, IT IS NOT JUST IMPALAS THAT ARE HAVING THIS TROUBLE; IT IS ACROSS THE ENTIRE PRODUCT LINE OF GM MODELS. *TR

FOR OVER A YEAR, I HAVE HAD PROBLEMS WITH THE ELECTRONIC SYSTEM FOR MY 2004 CHEVY IMPALA. FOR SEVERAL MONTHS, THE SECURITY LIGHT IN MY DRIVER?S PANEL INTERMITTENTLY DISPLAYED WHEN I PLACED THE KEY IN THE IGNITION AND MY CAR FAILED TO START. THE CAR WOULD EVENTUALLY START AFTER 15 ? 30 MINUTES. AT FIRST, THIS OCCURRED SPORADICALLY BUT THEN BECAME A MORE COMMON OCCURRENCE. WHEN I TOOK MY IMPALA TO A LOCAL AUTO-REPAIR SHOP, THEY WERE UNABLE TO DIAGNOSIS THE EXACT PROBLEM. THEIR EQUIPMENT REPORTED A NUMBER OF ELECTRONIC ERRORS BUT THEY WERE NOT ABLE TO PINPOINT THE PRECISE CAUSE OF THE CAR?S ISSUES. INSTEAD, THEY OFFERED TO RESET THE ELECTRONIC CODES AND ADVISED ME TO BRING MY CAR BACK AT THE FIRST SIGN OF ANY ELECTRONIC ISSUES. MY IMPALA OPERATED FOR THE NEXT FEW MONTHS WITHOUT ISSUE. HOWEVER, A NEW ELECTRONIC ISSUE EMERGED WITH MY VEHICLE. I NOTICED MY CAR BEGAN TO ACCELERATE AUTOMATICALLY. FOR EXAMPLE, IF I WAS AT A COMPLETE STOP, THE CAR BEGAN TO ACCELERATE AT A MODERATE AMOUNT OF SPEED AS SOON AS I RELEASED THE BRAKE. LIKE THE PREVIOUS ISSUE, THIS PROBLEM FIRST OCCURRED INTERMITTENTLY AND SOON PROGRESSED TO A REGULAR OCCURRENCE. WHEN I TOOK THE IMPALA BACK TO THE AUTO-REPAIR SHOP, THE MECHANICS STATED THE AUTOMATIC ACCELERATION WAS DUE TO A FAULTY IGNITION SENSOR. AFTER I HAD THE FAULTY IGNITION SENSOR REPLACED, THE IMPALA ONCE AGAIN RAN WITHOUT ISSUE FOR A FEW MONTHS. HOWEVER, THE SOLUTION PROVED TEMPORARY AS THE PREVIOUS AUTOMATIC ACCELERATION ISSUE RETURNED. I ONCE AGAIN TOOK MY CAR TO THE AUTO-REPAIR SHOP AND ONCE AGAIN, THE MECHANICS BLAMED A FAULTY IGNITION SENSOR. AT THIS POINT, I HAD THE MECHANICS REPLACE THE IGNITION SENSOR. SINCE THAT POINT, MY CAR HAS OPERATED WITHOUT ISSUE UNTIL TODAY. THE SECURITY LIGHT IN MY DRIVERS PANEL NOW CONTINUALLY DISPLAYS WHENEVER I DRIVE. I FEEL AS IF I AM AT THE END OF MY ROPE. I HAVE SPENT A CONSIDERABLE AMOUNT OF MONEY TO RESOLVE THIS ISSUE TO NO AVAIL. *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. 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.
