There are 1 owner-reported lighting complaints for the 2017 Audi A4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The headlights on my 2017 Audi A4 have developed stress cracks in the headlamp housing. According to the inspection performed by an authorized Audi dealer, these cracks will obscure headlight projection and lower the visibility range at night. The dealer specifically noted there were no signs of outside influence or misuse, and the issue is likely due to internal headlight temperature, external ambient temperature, and age. This defect directly impairs visibility and makes it unsafe to drive the vehicle at night or in low-light conditions. Headlights are a critical safety system. The problem has been confirmed and documented by the Audi dealership in a written inspection report. Audi of America has acknowledged that the defect is unrelated to misuse but refuses to fully assist with repairs, despite admitting it impacts visibility. The issue is ongoing and worsens with time. There were no warning lamps or dashboard messages related to the defect prior to its discovery. The vehicle and documentation are available for inspection upon request. This is a safety concern that puts me and others at risk due to reduced nighttime visibility.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
