Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When using low beam head lights, over half of the windshield ( top down) is blacked out, causing a restricted vision. There is a slight increase in vision when vehicle is being driven on an up hill grade. Vehicle was taken to the Gmc dealership for correction. Service manager drove the vehicle home and experienced the reported problem. Solution to correct the restricted vision,was to adjust/raise the low beam headlights so they would shine higher to the maximum allowable by state law. This adjustment raised the black out level by a very limited level. Problem still exists. …”
