MAZDA Complaints

I am being told there is a crack in the cylinder head that is a known issue for these vehicles. I have done some research online and it says that they installed defective cylinders in vehicles that were made between the years 2018-2020 leaving vehicle owners to pay thousands of dollars out of pocket due to a manufacturing defect. My car was smoking and smelling like something burnt even inside the car causing the driver to inhale those fumes, I took it to the shop and it turns out that the cylinder head is cracked and leaking the oil.

The contact owned a 2020 Mazda CX-5. The contact stated that while driving under 45 MPH, the TCM received a false data sensor warning, causing the vehicle to enter LIMP Mode. The contact stated that during the failure, the smart brake feature, Adaptive Cruise Control, and other unknown ADS features and warning lights were illuminated. The contact stated that the failure with the ADS system prompted the vehicle to come to a complete stop while driving 45 MPH. The contact parked and turned off the vehicle to troubleshoot the ECU after the failure had occurred. The contact restarted the vehicle, and the adaptive cruise control warning light, smart brake feature, and ADS radar features returned. The vehicle was not repaired. The manufacturer was notified about the failure. The failure mileage was 140,000.

Cracked cylinder head probably caused by cylinder deactivation causing catastrophic oil loss on the highway. Upon researching this, I see that it is a known issue with Mazda. My car is now in the shop awaiting repairs. It only has about 35,000 miles on it. This is obviously a known defect and is simply not acceptable.

The contact owns a 2007 Mazda Mazda3. The contact stated that while driving 5 MPH and making a turn, the steering wheel was difficult to turn to the left or the right. The check engine warning light was illuminated and flashing. The contact stated that the steering then seized. While checking the NHTSA.gov website, the contact associated the failure to NHTSA Campaign Number: 10V374000 (Steering). The vehicle was taken to the local dealer, who confirmed there was no recall coverage on the VIN related to the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case, and confirmed there was no recall coverage for the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 195,081.

Mazda has messed up headlights and it is very dangerous. I have to drive with high beams on continuously! The low beams point straight down to the road, looks like even with the bumper, you cannot see anything. It looks like you don’t have lights on. Took it to dealer and they say it’s the housing and it’s a Mazda thing and don’t do anything to fix it. I have tried every bulb available for Mazda and nothing helps. They need to fix this. I see SEVERAL owners with the same complaints! Please don’t overlook this as it is very dangerous and may cause deaths.

The infotainment system consistently changes stations and volume on its own. Knob will not allow you to make adjustments . Contacted dealer and infotainment Is not covered under warranty , or extended warranty. Now the collision notification is not working. Warnings from system that it has failed and causes system to not Register any movement . This has been going on recently. Now have to drive it as it doesn’t have the system. And have to use my Apple play for radio as infotainment keeps failing to include radio and navigation Told by dealer that the infotainment system is not Mounted into the dash and sticks up , so the heat from sun and summer has fried th system. Has been ongoing for over a year just found site to report it . Will not buy another vehicle with infotainment system sticking up out of dashboard

Steering it getting stuck when Turing from left to center. It also make brake squeaking.

When doing a sustained turn at highway speeds of 50+ mph, the steering wheel sticks and does not return to center. I had to forcefully return the wheel to center which caused a jerk in the steering. This happened 10+ times on a recent road trip I took (200 miles). I brought the car to Mazda afterwards and they are replacing the steering rack.

I am reporting a serious steering safety issue. I was told a steering recall had already been fixed before purchase. About four months later, the steering wheel began locking or strongly resisting movement while driving on curvy roads at speeds over 50 mph. When this happens, the wheel does not return to center and requires force to correct, creating a loss of steering control. I took the vehicle to Passport Mazda in Maryland on January 2, 2026. The dealer stated the entire steering wheel panel needs replacement and the part is backordered until March 2026. This is a dangerous defect in a recently recalled system and needs investigation.

With no prior warning, just after turning into driveway, my car got stuck and would not move. It gave clicking sounds and would not move no matter which gear it was in. The towing service person needed a dolly in order to safely lift the vehicle onto the towing bed because the front, driver’s side tire would not move and was pushing into the fender. So far, the control arm and axel are completely separated from the car. Further investigation is ongoing to determine the extent of the spontaneous injury. This all happened without warning.
