2004 CHEVROLET IMPALA — Complaint #664655
Open-data reference.
NHTSA Complaint about EXTERIOR LIGHTING:HEADLIGHTS:HIGH/LOW BEAM DIMMER SWITCH filed April 7, 2008
NHTSA complaint #664655 (ODI reference 10223566) concerns a 2004 CHEVROLET IMPALA and was filed on April 7, 2008. The owner reports the failure occurred on April 4, 2008. The vehicle had 50,000 miles on the odometer at the time of the incident. The report was geocoded to Oregon based on the filer's self-reported location. The affected component is categorized as exterior lighting:headlights:high/low beam dimmer switch, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same CHEVROLET IMPALA cohort independently describe similar exterior lighting:headlights:high/low beam dimmer switch failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2004 CHEVROLET IMPALA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I HAVE A 2004 CHEVY IMPALA THAT HAS HAD PROBLEMS WITH WARPED ROTORS, WHICH I HAD REPLACED. THEN A WHEEL BEARING WENT BAD. TOOK VEHICLE TO CHEVY DEALER. THEY DIAGNOSED IT AS LEFT FRONT HUB BEARING BEING BAD. I HAD LEFT FRONT HUB BEARING REPLACED AND PROBLEM WASN'T FIXED. TURNED OUT IT WAS RIGHT FRONT HUB BEARING THAT WAS BAD, SO BOTH ENDED UP REPLACED. A FEW WEEKS LATER "SERVICE TRACTION SYSTEM" LIGHT STARTED COMING ON EVERY DAY AND SHUTS OFF THE ABS AND TRACTION CONTROL SYSTEMS. OUTSIDE TEMPERATURE AND WEATHER CONDITIONS DON'T MAKE ANY DIFFERENCE. ALSO HAVING PROBLEMS WITH HEADLIGHTS GOING FROM HIGH BEAMS TO DIM. SOMETIMES IT TAKES TWO OR THREE ATTEMPTS BEFORE IT WILL GO FROM HIGH BEAMS TO DIM. I'VE NEVER HAD THESE KINDS OF PROBLEMS WITH CHEVROLET'S BEFORE. I'VE HAD CHEVROLET'S WITH 150,000 MILES ON THEM AND HAVE NEVER HAD TO REPLACE ROTORS, WHEEL BEARINGS, OR HAD ABS PROBLEMS BEFORE, JUST NORMAL MAINTENANCE. *TR
