Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Car headlights periodically flicker and turn off under normal conditions. Driver side flickers on acceleration and passenger side will flicker and turn off completely during acceleration or braking. Have to switch the headlights completely off and back on for them to light up again. I have the bi-xenon hid adaptive headlights factory installed on my car. …”

NHTSA complaint #10534346, filed 2013-08, 51,000 miles

“My right headlight has been flickering for about 3 months, and a few times it has gone out completely. Turning the headlights off and back on fixes it for a couple days. I waited to take it to the dealer until it needed maintenance, and also so there would be more DTC evidence for them to troubleshoot with. The left headlight started doing the same thing so I took it in. Audi cannot replicate and will not replace the headlights.”

NHTSA complaint #10824769, filed 2016-02, 105,000 miles

“I was driving down the highway and have continuously gotten the dipped light warning on my display. My lights procceded to flicker and then shut off. I was driving right next to a car and had to pull over because they wouldn't come on. It took 15 minutes before the headlights returned to normal. I was extremely scared when my headlights turned off. This is a big safety issue and has occurred 3 times since then. I have replaced the bulbs and that did not solve the problem. …”

NHTSA complaint #10608787, filed 2014-07, 101,000 miles

“I currently own a 2005.5 Audi A4. My headlights constantly flicker, which is dangerous at night. I have been looking on Audi-tech forums and this seems to be a real problem with many Audi vehicles. When I first got the car, I used to get a flickering problem but the dealership fixed it by replacing the bulbs. However, I do not think it is the bulbs because the problem has apparently flared up again. Please check into this as it may be reason for a recall.”

NHTSA complaint #10324754, filed 2010-04, 63,000 miles

“I purchased the vehicle on 02/11/2012 and that very evening when I had the opportunity to use the lights, my right light began to flicker and then failed completely. This really unnerved me as I was in an area with no street lights. And didn't really know what was happening. I instinctively turned the lights off and then on again, and this made them come back on. Unfortunately, this happened numerous times that night. I feel this is a blatant safety issue especially as I had family members in my car and their well being was compromised. …”
