WHILE DRIVING A 2003 PONTIAC GRAND PRIX GTP TRIED TURNING ON THE DASH LIGHTS AT DUSK ONLY TO FIND THAT THE DASH LIGHTS AS WELL AS THE HEAD LIGHTS LOW AND HIGH BEAM WOULD NOT COME ON. AFTER HAVING THE DEALERSHIP LOOK AT THE VEHICLE IT WAS FOUND THAT A PLUG CAME LOOSE CAUSING THE LOSS OF BOTH LOW AND HIGH BEAM LIGHTS. I FIND THAT THIS COULD POSSIBLY BE A SAFTY HAZARD AND FILL THAT THE LOW AND HIGH BEAM SHOULD BE ON SEPARATE CIRCUITS SO AS TO NOT LOOSE BOTH LIGHTS AT NIGHT.*AK

Reading these

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
