We have classified the 69 complaints from 2004 Chevrolet Impala about EXTERIOR LIGHTING into the following categories.
1) events leading up to the failure - it all started out of the blue about 2 weeks ago. i have an intermittent failure of the blinker mechanism of the turn signals. when it does not work, the lever is turned for either left or right turn and the signal stays lit, but not blinking. most of the time, thoughout the day, the signals blink properly. 2) failure and its consequences - this is obviously a safety issue in that drivers following me would not be as alert to a non-blinking light as they would be for a blinking light. 3) both myself and my local gas station removed and and reseated the possible offending fuse and associated relay module. he even indicated that both chevrolet and pontiac cars have turn signal arms with shorts in them. i could not find any recalls indicating a short in the turn signals.
The new model year 04 chevrolet impala sedans have poorly designed and or mis-adjusted daytime running lights, causing blinding glare to on coming drivers, drivers in front of these vehicles and pedestrians walking at night. these excessively glaring lights distract and cause eye pain to other drivers and temporary blindness. this is a serious safety problem that needs to be addressed especially for pedestrians walking against traffic at night.*ak
