Open the full vehicle complaint log (all categories)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. OBVIOUSLY THIS IS A MAZDA SAFETY ISSUE. MY KIDS DON'T NEED TO HAVE THE ANXIETY OF THEIR MOM BEING PULLED OVER WHEN DRIVING THEM HOME AFTER DARK, BECAUSE REST ASSURED THE AMERICAN MADE POLICE CAR BLUE LIGHTS ALWAYS WORK! I HAVE A CLEAN DRIVING RECORD SO LUCKILY I DON'T GET A TICKET AND JUST SENT ON MY WAY TO ONCE AGAIN FIX A BULB THAT ISN'T BROKEN! THIS SHOULD BE A MAZDA RECALL BECAUSE IF I CAN'T GET A STICKER WITH A BULB OUT THEN IT'S A "SAFETY ISSUE"! PLEASE HELP!
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.
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.
