“I own a 2012 Mazda 6 which now has approx. 72,000 miles. The front low beam headlights went out while I was driving in a rainstorm at night. Luckily my high beams stayed functional. After pulling over to check out the issue I hit the driver side headlight assy (out of frustration) and the low beam light came on. I did the same to the other side and that light came on too. As soon as I started looking on the internet about this. I see that there are many people having the same issue with Mazda headlights. …”
NHTSA complaint #10786172, filed 2015-10, 73,500 miles“At around 50,000 miles, I had a headlight (low beam) go out on me. I had it replaced on the driver side. A few weeks later, the passenger side headlight went out and had to get that replaced. These are hard to get to if you do not have the right tools so each time I had to take it in for service. At 65,000 miles, I had my engine and battery light come on. I turned the car off and then back on and they went away. I then tried locking the car, and my car will not lock from the inside or with my remote. The car will unlock, but will not lock no matter what I do. …”
