NHTSA Complaint #11193933 — 2016 MAZDA CX-5

PURCHASED WITH JUST 50K MILES. TOOK TO MAZDA FOR SERVICE LIGHT. NOTIFIED THE DIFFERENTIAL NEEDED REPLACEMENT CITING 2 TB (10155436 AND 10145248) CLEARLY IDENTIFYING THE ROOT CAUSE AS DEFECT IN MANUFACTURING. FURTHER INVESTIGATION PROVIDED CLEAR PROOF OF MAZDA'S ASSESSMENT WITH THE DIFFERENTIAL AND POINTING TO THE TB'S AS CASE FOR THE CLAIM APPROVAL. PICTURES SHOW YEAR'S LONG BUILDUP OF RUST, BROKEN COUPLERS, WATER CONTAMINATED OIL, METAL SHAVING. ALL REFLECTIVE OF THE DAMAGE CREATED BY THE DEFECTIVE DESIGN INDICATED IN THE TB. THE WARRANTY CLAIM WAS DENIED BECAUSE OF THE RELATED ISSUES WITH THE DEFECTIVE SEAL ALLOWING DAMAGE TO THE DIFFERENTIAL AND RELATED PARTS. ALSO EFFECTIVELY VOIDED MY POWER-TRAIN WARRANTY COVERAGE. THIS PRESENTS A HAZARD OPERATING THE VEHICLE AT CERTAIN SPEEDS WITH BROKEN METAL PARTS IN THE TRANSFER GEARS. I THINK IT REQUIRES A RECALL BECAUSE IT IS INEVITABLE WATER, RAIN, SNOW, EVEN A CAR WASHES WILL GET INTO THE SYSTEM BECAUSE OF THE FAULTY DESIGN. FACTS: VEHICLE HAD PRIOR MAZDA SERVICE AND THERE IS NO EVIDENCE TO SUPPORT MAZDA PRESENTED THE REPAIR OPTION PRIOR TO THE DASH LIGHT APPEARING. MAZDA HAS NO SERVICE OR WARRANTY CHECKS IN PLACE THAT DETECTS THE DAMAGE. THE TIME IT TAKES FOR THAT LEVEL OF RUST BUILD UP TO ACCRUE IS SELF-EVIDENT THIS IS MAJOR SAFETY ISSUE THAT SHOULD REQUIRE A RECALL BUT ALSO A MATTER OF ETHICS AND INTEGRITY. WATER IN YOUR REAR AXLE WILL UNDOUBTEDLY CAUSE FAILURE TO SEALED MECHANICAL COMPONENTS. MAZDA WAS AWARE OF THIS ISSUE FOR YEARS YET DOES NOT OFFER THE CONSUMER ANY ADDITIONAL COVERAGE OR ANY WAY TO PROTECT THEMSELVES FROM A HEFTY REPAIR COSTS OR RISK OF HARM DUE TO THIS FAILURE. THE VEHICLE ITSELF HOLDS EVIDENCE OF DRIVE-TRAIN AND ITS WARNING SYSTEM ARE BOTH DEFECTIVE BECAUSE THE HISTORIC ERROR CODES/MILEAGE IN ITS INTERNAL MEMORY. THE SYSTEM FAILED ALERTING THE ISSUES WELL AFTER THE MANUFACTURER'S WARRANTY EXPIRED.
