MAZDA Complaints

2021 Mazda CX-9 Low Oil Light came on at around 18,900 miles (2/10/2023 and 2/11/2023). Took to Mazda, and they said there was defective valve stem seals that can allow oil to leak into the engine’s combustion chamber. Vehicle is currently with Mazda service department to be fixed.

The contact's daughter owns a 2016 Mazda CX-3. The contact stated that while her daughter's vehicle was in reverse(R), the vehicle failed to stop upon the depression of the brake pedal. There was no warning light illuminated. The contact stated that her daughter engaged the parking brake; however, the vehicle continued to roll back until the vehicle hit a curb and stopped. The vehicle was taken to an independent mechanic who noted that the failure was not brake related but was a computer malfunction. The contact called a dealer who referred her to the NHTSA hotline for assistance. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 57,000.

The infotainment center has been randomly changing settings and radio channels. When it is taken over, I cannot regain control of it until it stops. I've seen online this called "ghost" controlling. It will increase the volume so lout, that I jump sometimes. Also, the rear camera mode of the system froze while I was backing up causing me to hit a vehicle parked across from me.

I drove my wife to work and noticed that the car was stuttering and had weak acceleration. I parked in my garage and a couple of hours later returned to see a massive oil leak on my driveway, I had to tow the car to the nearest dealership where a cracked cylinder was diagnosed. There was also a terrible burning smell. If the massive leak happened on an acceleration ramp or on the highway there could have been an accident.

My car is a 2021 CX-5, Turboed AWD vehicle. It keeps consuming oil. I took it to the dealership, Sandy Sansing Mazda in Pensacola, where I purchased the car. The technicians informed me that these models are known to consume oil. They did not tell me that when I bought it in September of 2022! They had a technical service bulletin, which works as a policy for the company, with a range of VIN numbers that indicated the vehicles with those VIN numbers are likely to have a manufacturing defect that allows oil to leak into the combustion chamber. My car's VIN number falls within that range. While I purchased this vehicle to drive long distances, including to see and care for my mother in NC, who was recently diagnosed with terminal brain cancer, and to Alaska from FL, my newish (pre-certified) car runs out of oil quickly. It must be causing internal damage (plugs, wires, exhaust, and the cylinders). When I asked the Mazda techs to fix the issue, they informed me they would not uphold the warranty, because I put oil in the vehicle. I was 400 miles away from home on a trip, on a Sunday, when a light in my car came on that indicated the car was low on oil. Why wouldn't I put oil in it? It is not safe to drive a vehicle with no oil, as it could cause the engine to stop working. One time, my oil pump went out in a 2002 Tacoma, and my camshaft welded itself together, or to other parts of the engine, at 70 mph down a highway. I lost power steering, power brakes, power in general. The timing belt was instantly shredded. It's not safe to drive cars that consume oil so rapidly between recommended changes. Mazda would not uphold their warranty responsibly, and they have known about the defect for some time, yet they are still selling cars that are unsafe to drive.

During Virginia State Vehicle Safety Inspection in January 2023, the inspector noted a problem with severe rust in the rear Cross-Member (part 28-800A). The rear Cross-Member is severely rusted and crumbling at fastening and stress points. The driver side (left side) of the cross-member that secures the top of the (left) coil spring is so deteriorated that the left stopper (28-111B) became unattached from the top of the mount and is freely floating inside the coil spring, causing visible damage to the coil spring when the stopper (made of steel with rubber on bottom) and the coil spring come in contact. The same problem is occuring on the passenger side (right) of the rear crossmember as the upper mount is severely rusted and crumbling. If the Cross-Member mounts collapse or the Coil Springs break while the vehicle is moving, the driver would have extreme difficulty maintaining safe control of the vehicle.

The engine will not turn off when pressing the start/stop button while the transmission shifter is in park.

I bought Mazda CX30 in 2020 and the battery already starts to fail. The engine light and the battery light are on suddenly when I was driving. Then, after a while, when I restart the engine and it starts to work again. However, it happens for two times within a week. I have sent the car to the Auto Zone and the nearby car auto repair company to check the car. However, they said they cannot detect anything as the engine light and the battery light are on again this time. It is so dangerous when the car suddenly stop in the middle of the road when I was driving. I am so lucky that this accident happened during rush hour and there were heavy traffic.
