“My vehicle & many many more are effected with the daytime driving lights that come on when vehicle is put in gear. Great idea, but no taillights ever come on. I have almost run into multiple vehicles in foggy conditions. It also has a negative purpose in snow & rain. Can't believe this has not been brought to your attention before this.”
NHTSA complaint #11399508, filed 2021-03, 3,599 miles“19 Sep 2025. The headlights turn off at night while driving. With the switch in the auto position, I turned the switch to off then back to auto and they came back on for a short period of time. They turned off again, I turned them to on , they came back on for a brief period. I had to keep switching the headlight switch from on to off and back to on every 20 to 30 seconds (estimated) to keep driving. The dealership could not schedule a diagnosis until 8 Oct 2025. This is a potentially fatal issue.”
