Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
NHTSA complaint #11243102, filed 2019-08, 82,000 miles“The wiring harness on the headlight for my Mazda CX-9 has and continues to melt, causing the bulb to be useless. The only issue that will seem to correct this issue is installing new headlights. According to my research this is a problem that is common to Mazda CX-9 vehicles.”
