1.Instrument cluster panel brightness does not adjust either too dim or too bright Mazda dealer stated no failures were found twice same responded. 2.

I keep getting a automatic emergency braking malfunction alert

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.

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...

Our vehicle has water drains or "weep" lines for the sunroof. We recently had the electrical system stop/start, dash lights remain on constantly after sitting in the driveway during the rain. We learned that if the drains become blocked that water leaks into the cabin directly onto the body control module (bcm). Because the bcm is not in a sealed or water-proof case, yet is soaked in these conditions, the vehicle is subject to electrical failure as a result. Replacing the bcm costs about $1,000. When we...

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.

Drivers low light ballast took on water and rusted out causing the headlight to short out.

I've replaced the passenger side low beam light on my 2010 mazda cx-9 yearly for the past 4 years thinking the bulb was blown. Only to have the socket wiggle loose shortly after installing the bulb. I've been pulled over at night for the 2nd time last week for the bulb being out - but I know it was on when I left the driveway. The socket doesn't hold the bulb in tight. You can tap the lens and get the bulb to come back on (sometimes) only until you hit another pot hole - then eventually the bulb blows again. ...

Tl* the contact owns a 2010 mazda cx-9. While driving various speeds, the driver side headlights failed to operate. The vehicle was taken to an independent mechanic where it was diagnosed that condensation entered the head lamp assembly and caused the fuse to become inoperable. The head lamp assembly was replaced. The manufacturer was notified of the failure. The failure mileage was unknown.

While traveling on the turnpike at 70 mph at night my entire dash board, including speedometer, warning lights and temperature controls and head lights and back lights went blank and dark. Pulled off road and shut engine off. Was going to call road service, but turned engine on and everything came on. Drove another 15 minutes and the entire dashboard and head lights went out. Pulled off road and shut off engine and turned it on again and all was working again. Got home safely without more problems. Same...

The driver's side low beam light went out. Upon taking the vehicle to the dealership I was advised it's not the bulb itself rather it's a component within the headlamp assembly which is corroded due to the build of of moisture within the lamp kit. This is a known problem & there is a service bulletin (service bulletin no.: Sb-09-003-13). The dealership stated mazda will not cover the repair and quoted me a cost in excess of $1,000 to replace the headlamp and related parts. I believe mazda to be responsible when there is a known problem.

Vehicle brakes lighting dim while coming to a stop and can not be seen from other vehicles approaching from behind on the road. When not replaced, stop light will run continually or not function, potentially causing premature bulb failure, safety issues and/or the transmission will not shift out of park. A failed stoplight switch will prevent the brake light from illuminating when the brake pedal is applied that may cause a collision and a life lost. *Tr

Tl* the contact owns a 2013 mazda cx-9. The contact stated that the low beam headlights were engaged and failed to illuminate the road beyond 5 feet. The failure recurred more frequently when driving on a mountainous road. The vehicle was taken to an authorized dealer, who informed the contact that the vehicle functioned as designed. The approximate failure mileage was 150.

The low beam headlamp connector on the passenger side melted inside the headlight causing the light to fail. Now the driver side has done the exact same thing causing the light to fail. This could create a serious injury and requires the replacement of a defective light connector. *Tr
