In owners' words
What Sierra 3500 owners report
Recent exterior lighting complaints filed with NHTSA, shortened. Personal details are removed.
HEADLIGHTS ON THIS TRUCK HAVE ALWAYS BEEN WEAK, DISTANCE IS NOT LIT UP AND IN RAINY WEATHER ON THE HIGHWAY IS VERY POOR EVEN WITH FOG LIGHTS ON. THE HELP FROM THE FOG LIGHTS IS MINIMAL. THIS IS A KNOWN PROBLEM BY THE MANUFACTURER AND IS REPEATED MANY MANY TIMES ON VARIOUS GM RELATED OWNER FORUMS.…
LIGHTING IS VERY POOR, HARD TO SEE AT NIGHT. IT'S NOT SAFE TO DRIVE IT AT NIGHT. WHEN IT'S RAINING IF HEADLIGHTS ON ITS FOGGING UP FROM INSIDE.
I AM AFRAID TO DRIVE AT NIGHT BECAUSE THE HEAD LIGHTS ARE TERRIBLE. I COULDN'T SEE THE TIRE CARCASS LEFT ON THE HIGHWAY EARLY ENOUGH TO SWERVE AROUND IT. I HIT IT WITH THE REAR WHEEL AND DID APPROX. 6000.00 DOLLARS DAMAGE TO THE VEHICLE.
