There are 2 owner-reported lighting complaints for the 2009 Mazda CX-9in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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
RE: MAZDA CORPORATE FILE NUMBER [XXX] I WANT TO MAKE A COMPLAINT THAT MAZDA USA AND FREMONT MAZDA DEALER DECLINED A VALID DEFECT REAR LED TAIL LIGHTS WHEN I EXERCISE IT THROUGH MAZDA FACTORY NEW CAR WARRANTY. I HAVE ALREADY CONTACT MAZDA CORPORATE FOR THIS DEFECT PROBLEM AND WORKED THROUGH THE LOCAL MAZDA DEALER (FREMONT MAZDA) TO DIAGNOSE THE PROBLEM. FREMONT MAZDA DISHONESTLY DECLINED THE VALID DEFECT PROBLEM AND WHEN I LATER TRYING TO SHOW THE DEFECT EVIDENCE (PICTURES) TO MAZDA USA, MAZDA USA CORPORATE CHOSE TO IGNORE ME AND CONCURRED WITH THE MAZDA DEALER'S DIAGNOSIS. EACH OF 2009 MAZDA CX-9 LED TAIL LIGHT HAS 12 LED PIXELS. EACH LED TAIL LIGHT HAS A FEW CROOKED LED PIXELS ARE DIM AND AIMED AT THE SKY AND GROUND BUT NOT TO THE TRAFFIC BEHIND. A DRIVER DIRECTLY BEHIND MY CX-9 ONLY CAN SEE ABOUT 2/3 LED PIXELS (8 OUT OF 12) AND THE OTHER LED PIXELS ARE DARK. THE CROOKED LED ARE LIT BUT YOU CAN ONLY SEE THAT DIRECTLY LOOKING DOWN FROM TOP OF THE CAR OR VICE VERSA. I BELIEVE THIS LED TAIL LIGHTS DEFECT IS A VALID SAFETY CONCERN. LED HAS A DISCRETE AND NARROW LIGHT PATTERN COMPARES TO THE INCANDESCENT BULBS. A GOOD SET OF LED TAIL LIGHT SHOULD HAVE ALL ITS PIXELS AIMED TO THE TRAFFIC BEHIND, NOT TO THE SKY AND GROUND. HOWEVER, MAZDA (BOTH THE DEALER AND USA CORPORATE) REFUSED TO TAKE MY CONCERN SERIOUSLY AND REFUSED TO WORK WITH THEIR CONSUMERS. I REASONABLY DOUBT THEY STRATEGICALLY WORK TOGETHER TO REJECT A VALID SAFETY CONCERN THAT MIGHT POTENTIALLY CAUSE MAZDA USA MORE TROUBLE DOWN THE ROAD. POSSIBLY THEY THINK I WILL WALK AWAY QUIETLY JUST BY REJECTING MY REQUEST. I AM MORE THAN HAPPY TO PROVIDE THE PICTURES OF THE BAD LED PIXELS UPON REQUEST. I AM ALSO HOPING IF A THIRD PARTY PROFESSIONAL SPECIALIST CAN TAKE A LOOK OF THE BAD TAIL LIGHTS SO A SOUND JUDGEMENT CAN BE MADE. I WANT A SET OF NOT DEFECTED NEW LED TAIL LIGHTS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).*TR
