MAZDA Complaints

my driver-side seatbelt buckle has been jamming since about one month after purchase. When I brought the issue to the dealership, they were able to temporarily fix it using an air compressor, citing that the buckle was full of "small debris". Upon further inquiry, I was told the debris consisted of "air particles and dust" and was advised not to leave the door open or drive with the top down. Given that this is a convertible, such a recommendation is unreasonable. It is unacceptable for a seatbelt buckle, one of the most critical safety components of a vehicle, to malfunction under normal usage conditions, especially in a brand-new car. This is available for inspection upon request. This malfunction prevents me at times from fully engaging my seat belt.

The contact owns a 2010 Mazda Mazda6. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently veered to the left. There was no warning light illuminated. The contact stated that the vehicle became difficult to steer. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the engine cradle had failed and was severely rusted and needed to be replaced. The vehicle was not repaired. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 114,000.

While driving at approximately 20 mph on a residential road during slushy conditions, the side curtain airbags deployed without warning. There was no collision, no impact, and no indication of a rollover or crash. A police officer arrived and completed a report, which noted no crash had occurred. The airbag deployment caused damage throughout the vehicle, and the car has since been declared a total loss by the insurance company. The manufacturer initially delayed responding for over two weeks. When they did respond, they claimed the airbags deployed properly based on “connected data” indicating a possible rollover. However, they refused to provide any proof of this data, any Event Data Recorder (EDR) data, or any technical explanation of what triggered the deployment. No warning lights or messages were displayed before the deployment. The local dealership that had the vehicle inspected the physical damage but did not confirm a rollover or any significant structural event. Mazda has refused to release their investigation data and instead closed the case without transparency. This deployment caused significant damage and created safety and financial risk. I am concerned that this incident may reflect a larger issue in airbag deployment logic that other owners may also face.

The contact owns a 2017 Mazda CX-5. The contact stated that while driving 30 MPH, the air bag warning light illuminated on the instrument panel. The vehicle was taken to the dealer, who diagnosed a failure with the air bag connector. The vehicle was repaired, but the failure reoccurred 9,000 miles later. The vehicle was taken back to the dealer, who again diagnosed a failure with the air bag connector. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 24,000.

The contact owns a 2019 Mazda CX-5. The contact stated that while the vehicle was parked, the contact discovered an abnormal odor coming from the engine compartment. No warning light was illuminated. The vehicle was taken to a dealer, where it was diagnosed that there was a cracked cylinder head and that the cylinder head needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 26,000.

On the freeway going 60 MPH, the safety system malfunctioned and applied maximum braking - as if I was going to collide with something in front of me. It was frightening. There was a 1/4 mile of open road in front. It happened 2 more times in the next 2 miles on the interstate. Background: I had been driving through a snow storm for a couple hours prior to the incident and I received a forward camera dirty warning. I was in the left lane (of 3 lanes) with a concrete barrier about 15 ft to my left. All 3 times, there was a semi truck & trailer on the right. I was in no danger of collision. I took the CX50 to the Mazda Dealer and the issue was escalated to the regional service techs who said the auto was "working as intended" I vehemently disagree. I am lucky there was no one driving close behind me, otherwise there would have been a terrible accident

Driver door does not open from inside the vehicle. Door opens when opened from outside the vehicle.

My 2018 Mazda CX-5 with just over 45,000 miles is showing the dreaded cracked cylinder head symptoms. Coolant is leaking causing a very noticeable burning smell in the cabin and faint smoke emanating from under the hood. My CX-5 has followed the maintenance schedule at the dealership that the vehicle was purchased. At this point the dealership has not been helpful at all. Mazda MUST start including 2018 CX-5s to CSP11 (covers 2019 CX-5s).
