Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“This was a rental vehicle, not my personal vehicle, but is applicable to multiple brands and models. The safety issue is due to the headlight modes. The default mode is off, yet the drl's remain on. These are bright enough that you can drive in the middle of the night and not realize that your actual headlights are off, which means that the tail lights are off. I have been seeing several vehicles every day with people driving with no lights on, even in poor visibility. The default should be for the headlights to be in auto mode or drl's must be off when you select off. …”
