Example complaints

“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. There are over 100 similar Mazda complaints - mostly passenger side. …”

“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.”

“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.”

NHTSA complaint #10823769, filed 2016-02

“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.”
