MAZDA Complaints

Steering is sticking. Regardless which way I am turning, I have to put force in the steering to make it turn

Brake booster failure in less than two years of ownership. It seems to be an issue with A LOT of these models. Very unsafe to have any brake failure

The vehicle experienced a sudden and complete engine stall while idling immediately after fueling the gas tank to capacity on a day with high ambient temperatures (over 100°F). Leading up to the stall, the vehicle was subjected to temporary auxiliary loads (Max AC running and active steering input). Immediately following the stall, the vehicle exhibited a hard-start condition and would not catch fire. After sitting turned off for several minutes, the vehicle restarted normally. The incident left no Diagnostic Trouble Codes (DTCs) or Check Engine Lights. Independent of this event, the vehicle intermittently exhibits a raw gasoline vapor smell inside the cabin at idle, alongside slight hesitations during low-speed steering maneuvers. This presents a safety hazard due to unexpected loss of motive power immediately after refueling in high-traffic gas station environments.

Low pressure fuel pump failure with 75,575 miles on odometer. Fuel pump completely seized. Car was parked at a retail location and would not start. Upon troubleshooting, mechanic was able to determine the low pressure pump was not delivering fuel. Pump was replaced. Faulty fuel pumps could lead to hazardous conditions as they are mounted within the fuel tank. I feel this is too early in the vehicles life for this component to have completely failed.

The contact owns a 2018 Mazda CX-5. The contact stated that white smoke was coming from the engine compartment whenever the vehicle reached normal operating temperature. The contact stated that smoke entered the passenger’s side compartment through the air vents and was coming from underneath the hood. The contact stated that there was a burning odor coming from the engine compartment due to an oil leakage. The smoke impaired visibility while driving. The most recent failure had occurred while driving approximately 35 MPH on a city roadway. The vehicle was driven to an independent mechanic to be diagnosed, and then to the dealer for further inspection. The independent mechanic diagnosed the vehicle with a cracked cylinder head and recommended that the vehicle be taken to the dealer for additional diagnostic tests. The dealer diagnosed the cylinder head as porous and informed the contact that the cylinder head needed to be replaced. The manufacturer was notified and informed the contact that the repair would not be covered. The vehicle was not repaired. The contact stated that the failure had occurred intermittently and became more frequent and severe during hotter weather. The failure mileage was approximately 83,000.

My Mazda 2018, CX-5, Grand Touring, was diagnosed with a cracked cylinder head at 64,599 miles. This issue could posed a safety hazard for not only us but others on the road by: *Engine Failure / Sudden Loss of Power-A crack allows coolant and oil to mix or leak, leading to overheating and potential catastrophic engine seizure. A seized engine can cause sudden, unexpected loss of power — especially dangerous at highway speeds or during lane changes/merges. *Oil and Coolant on the Road-Leaking fluids drip onto the roadway, creating slick surfaces for motorcyclists and other vehicles — similar to a spilled oil hazard. This is especially dangerous on curves and in wet conditions. *White Smoke / Steam Billowing from Exhaust-When coolant enters the combustion chamber, it burns off as thick white smoke. This can instantly reduce visibility for drivers behind the vehicle, potentially causing rear-end collisions. *Fire Risk-If oil leaks onto hot exhaust manifolds or engine components, it can ignite. An engine fire can spread quickly and, in traffic, puts surrounding vehicles and occupants at risk. *Debris from Engine Destruction-In extreme cases, a severely overheated or seized engine can cause internal components to fail violently. Debris from a catastrophic engine failure can damage undercarriages of nearby vehicles or become road hazards. *Stalling in High-Risk Locations-A vehicle that stalls due to engine failure in a tunnel, on a freeway on-ramp, in an intersection, or on a bridge creates an immediate collision risk for surrounding traffic. This is part of why Mazda's handling of the cylinder head defect is so problematic — it's not merely a costly repair, it's a public safety issue that arguably warrants regulatory attention (NHTSA). We had NO warning lights, no overheating issues. Repairs have been made to the cost of almost $5400.00 *Please note there are many, many people complaining of this same issue on this model of car in multiple on-line forums.

My rear differential is going out at only 40,000 miles. Ive heard from many other people that this is a widespread issue, and i feel requires a response from the company.

The contact owned a 2020 Mazda CX-9. The contact stated that while driving approximately 60 MPH, a second vehicle crashed head-on into the front of the vehicle. During the head-on crash, no air bags inside the vehicle deployed. The contact sustained a concussion and right eye injury and later received medical attention. A Police report was filed at the scene. The vehicle was destroyed and towed to a local storage facility. No information was available concerning the second vehicle's occupants. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The local dealer was not contacted. The failure mileage was 130,000.

The radio is uncontrollable by driver. The radio the self dial from Bluetooth. Even if not connected, the radio surprises this driver by playing the radio unexpectedly at the highest rate. Due to the buttons not working, driver cannot turn down the radio causing safety concerns for being scared and distracted. There are no warnings. Mazda is unwilling to assess without pay.

The front driver-side lower ball joint suffered a catastrophic structural failure and sheared completely apart while moving. This vehicle was previously serviced under Safety Recall Campaign 15V451000 / Mazda Recall 8515G for this exact defect. The recall remedy part failed a second time, collapsing the front wheel assembly, ripping the CV axle completely out of the transmission casing, causing a hazardous transmission fluid spill, and leaving the vehicle stranded and immobilized in the middle of a live roadway in the dark
