MAZDA Complaints

The steering rack is the component that has failed. On multiple occasions while I am driving on the freeway the steering will randomly pull in the opposite direction of the turn that I am on. Or if it the pavement is uneven it will hit the bump and stick and get harder to steer or pull one way or the other. I have been in 3 near accidents at freeway speeds. I have taken it to the dealer and they say they can not replicate it so they are not fixing it or addressing my concerns. There are no warning lights and no warning when it is going to happen so I have to grip the steering wheel tightly with both hands to prevent from being pulled or pushed into and accident. It has already been recalled once for this same behaviour.

STEERING WHEEL SEEMS LIKE IT STICKS WHEN CORNERING OR TURNING WE ALMOST HAD AN ACCIDENT GOING AROUND A CORNER

Oil leak from defective head that occurred behind exhaust manifold leaking hot oil onto the hot exhaust causing the potential for fire. Leak started at 44,000 miles. This manufacture defect is not being covered by Mazda or a recall even though the high potential of fire and serious injury.

The contact owns a 2025 Mazda CX-70. The contact stated that while driving on several occasions at various speeds with the Lane Keep Assist feature deactivated, the steering wheel jerked to the left. The vehicle was towed to a dealer, and the failure was being investigated. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 19,000.

The contact owns a 2015 Mazda Mazda3. The contact stated that while driving at various speeds, or while attempting to reverse, the rear camera flashed on and off for approximately five minutes and then started working as intended. No warning light was illuminated. The vehicle was repaired under the NHTSA Campaign Number: 23V487000 (BACK OVER PREVENTION) by the owner of the vehicle; however, the fix failed to repair the vehicle. The contact stated that the failure had occurred after the recall repair was performed. The manufacturer was not notified of the failure. The failure mileage was 180,000.

My 2018 Mazda CX-9 with the SKYACTIV-G 2.5T engine has been diagnosed with a cracked cylinder head, cracked exhaust manifold, and cracked turbocharger at approximately 88,000 miles. This is a known design defect documented in Mazda TSB 01-002/23 and addressed by Customer Service Program CSP11, which extended the powertrain warranty to 10 years/120,000 miles for coolant leaks at the cylinder head. The TSB identifies exhaust manifold deformation and residual production stress as root causes of the cylinder head cracking. In my vehicle, the failure has extended to the exhaust manifold and turbocharger, both directly mounted to the cylinder head in the same high-stress zone. The turbocharger on this engine is a coolant-cooled unit. As coolant leaks from the cracked cylinder head, the turbocharger is deprived of its cooling supply, leading to excessive heat buildup and eventual cracking of the turbo housing. The turbo damage is a direct consequence of the cylinder head defect Mazda has already acknowledged. CSP11 covers the cylinder head but does not address consequential damage to the exhaust manifold and turbocharger caused by the same defect. I am requesting the NHTSA investigate whether Mazda's remedy is sufficient and whether a formal recall is warranted given the risk of sudden engine failure at highway speeds.

Steering wheel gets "Stuck" when making a sweeping left turn and needs force to return to neutral. Suspension "creaks" and "grinds" when going over bumps or hills.

RH LED headlight cooling fan failure. Diagnosed by Mazda dealer and quoted $2450 cost. Vehicle is just outside warranty coverage by 2900 miles. This is a very well known and documented problem that Mazda is not standing behind. Owners are removing the relay for their daytime running lights, rendering them inoperable in order to save wear and tear on the headlight cooling fans. This is a safety hazard.

The vehicle intermittently fails to start when pressing the push-button start system. The start/stop button becomes unresponsive despite normal conditions (key present, brake engaged, no warning indicators preventing ignition). This has now occurred twice within two years of ownership, indicating a recurring issue rather than an isolated incident. On the most recent occurrence, the vehicle was completely unable to start and required towing. The tow truck operator reported that he had towed four vehicles of the same make/model for the exact same issue within one week, suggesting a broader pattern affecting multiple vehicles. Safety Concern: This presents a significant safety risk, including: •Inability to start the vehicle in unsafe or emergency situations •Risk of being stranded in dangerous environments (e.g., roadside, extreme weather, unsafe areas) •Potential failure of the ignition system, which raises concerns about reliability of vehicle operation overall A malfunction in the start/stop system directly impacts the vehicle’s basic functionality and creates an unpredictable and potentially hazardous situation for drivers. Additional Notes: Given the repeated occurrence and reports of similar failures in other identical vehicles, this issue may represent a systemic defect that warrants investigation.

Engine throwing a code after dying at intersection. Found that it isa known issue for this vehicle and repair costs are astronomical. Diagnostic Summary: 2013 Mazda CX-9 (3.7L V6)Issue: Faulty Crankshaft/Camshaft Correlation (Code P0016)Current Mileage: ~160,000 miles Reported Symptoms: Extended cranking (long start), rattle upon startup, and rattle under light acceleration. The 2013 Mazda CX-9 is KNOWN for a serious issue where the internal water pump fails, allowing coolant to leak into the oil, which causes timing chain failure and potential engine destruction. I wish I knew this years ago...
