1 Headlights problem of the 2015 Mazda CX9

Failure Date: 12/15/2018

I've only had my Mazda for 10 months and have had the same problem twice. The right headlight socket has melted and rendering the bulb useless. I noticed the socket had been spliced into the old harness so I took it to the local Mazda dealer service. They gave me an estimate to install a complete new harness. To remove the light fixture, the bumper will need to be removed. The estimate for this was $643. 25! I purchased the wiring harness and with help installed it through the ports in the rear of the fixture in January 2019. Recently, the light stopped illuminating again only to find this same socket has melted as the previous one did. If this pattern persists, it could cost $1300 per year to have Mazda fix it. The spliced harness tells me that this has been a problem with this vehicle at least once before! before buying this Mazda I found a review on kelly blue book's website with one frustrated owner that had a similar reoccurring problem every 3 months. At the time I thought it may be an anomaly. I believe upon investigation you will find it's more of a perpetual safety hazard, inconvenience and expense. I will send documents and photos with this request for a recall investigation.

2 Headlights problem of the 2011 Mazda CX9

Failure Date: 11/01/2017

My driver side headlight went out a month ago. I changed the hid bulbs, the fuse and nothing was working. I took it to a Mazda dealer for my warranty when I bought it. After Mazda checked it out, they found my hid ballast was fried due to water condensation. My head light is not broken or missing any parts. My warranty will not cover it. I have read in several sites that this is common and Mazda know about it and has done nothing to fix it. I have been pulled over several times cause of this.
