NHTSA complaint #11768904

Owner complaint summary

I began hearing a loud engine noise similar to a lawn mower whenever my headlights would come on which includes just when I unlock my car. When I first took it back to the Mazda dealership for servicing and mentioned this to the service manager he told me it was an issue with the headlights that they’ve been seeing. They returned the car to me and said they did not hear it. Then after my warranty ended it got worse and when I brought it back to the dealership they stated they had never heard of this happening before and said that I brought my car for an air-conditioning issue. When identified that a service manager had told me that this is something they’re saying they then agreed to pay to have the headlight fixed. Initially they told me I was gonna have to pay approximately $1500 out-of-pocket because my warranty had ended to have it replaced. As I proved that I told them about this before the warranty was ended they covered the cost of it and replaced it. Two weeks ago the noise came back. When I look on the Internet and put in the search terms of loud noise when headlights come on is a common complaint. This seems to be a design flaw which is affecting the headlights causing a safety issue. Mazda should address this and issue a recall in my opinion.
