MAZDA Complaints

Breaks and gas pedal simultaneously stopped working while driving and steering wheel locked up

Started smelling burning oil in 2020 Mazda CX-5 non turbo with 34,000 miles. Auto shop states it is a cracked cylinder that will cost over $7,000 to repair. A Google search shows it is a known issue but Mazda has not extended the warranty for non-turbo models.

The contact owned a 2024 Mazda CX-50. The contact stated that while driving at an undisclosed speed, after exiting the freeway, the contact was distracted, and when the contact turned to face the road, the vehicle rear-ended the vehicle in front. The contact stated that from the impact, the vehicle that was rear-ended was pushed into the vehicle in front. The contact stated that the crash imminent braking and the forward collision warning failed to function as intended. The contact stated that the driver-side air bag and the knee air bag were deployed. The contact was unsure whether there was a warning light illuminated. A police report was filed. EMS was called to the scene. However, the contact refused to go to the hospital by ambulance. Afterwards, the contact went to the hospital. The doctor diagnosed that the contact had a swollen spleen on the left side. The contact stated that the shoulders and back were sore, and the left knee was swollen. The contact attended physical therapy. The contact was able to drive the vehicle back to the residence. The insurance company towed the vehicle to an unknown location and deemed the vehicle a total loss. The manufacturer was notified of the failure, and a case was opened where assistance was declined. The failure mileage was 16,937.

The contact owned a 2008 Mazda Tribute. The contact stated that while driving at approximately 20 MPH and attempting to make a turn, another vehicle unexpectedly T-boned the vehicle, impacting the passenger front side. The contact and a passenger sustained minor injuries, and the passenger was taken to a local emergency room. The contact suffered a back injury and was placed on medical leave from employment due to the accident. The passenger sustained bruises and lacerations. The contact stated that the driver and side curtain deployed; however, the front passenger airbag failed to deploy. A police report was filed. The vehicle was towed and deemed a total loss. The dealer was contacted. The vehicle was not diagnosed or repaired. The dealer referred the contact to the manufacturer for further assistance. The manufacturer was made aware of the failure. The failure mileage was approximately 245,000.

Vehicle CV joints failed at 6000 miles, dealership took over 3 weeks to replace them. They claimed multiple CX50 hybrid vehicles are impacted and lots of them already returning under the same problem

The touchscreen digitizer on the Mazda Connect infotainment system has developed a known defect causing constant phantom/ghost touch inputs. The screen registers random touches without any physical contact, causing the system to navigate through menus, change vehicle settings (including safety-related settings such as blind spot monitoring and heads-up display), exit navigation mid-route, change radio stations, and initiate phone calls to contacts without driver input while connected to Apple CarPlay. This is a significant driver distraction and safety hazard. When the system begins making random inputs, the driver must divert attention from the road to attempt to regain control of the infotainment system or end unintended phone calls. The issue occurs most frequently when the vehicle is stopped or at low speeds but also affects the system while driving. This is a well-documented hardware defect affecting 2017-2020 CX-5 models, acknowledged by Mazda under TSB 09-003/22. The cause is a failing touchscreen digitizer, not a software issue. Mazda has not issued a formal recall despite widespread reports. The component is available for inspection upon request. The vehicle has not yet been inspected by a dealer for this specific issue. No warning lamps or messages preceded the failure — the phantom touch inputs developed gradually and have worsened to the point that the infotainment system is nearly unusable. Current mileage is approximately 60,000-80,000 miles.

The vehicle's cylinder head has developed a structural crack at on the casting, a known manufacturing defect identified by the manufacturer in Service Advisory SA-037/23. This failure is causing pressurized engine oil to leak directly onto the hot exhaust manifold while the vehicle is in operation. The leaking oil is pooling on high-temperature exhaust components, creating a significant risk of fire while driving. The leak generates heavy smoke and noxious burning oil fumes that are entering the passenger cabin through the HVAC system, causing respiratory issues

To Whom It May Concern, I am submitting this complaint to report serious and ongoing safety concerns regarding my Mazda CX-90. I believe this vehicle presents a significant safety risk to occupants and other drivers on the road. Since the date of purchase, this vehicle has been subject to numerous recalls, repeated software updates, and multiple mechanical issues. The number of recalls alone raises concern about the safety and reliability of this model. In addition, the vehicle has been in service many times, and I have frequently been provided a loaner vehicle due to unresolved problems. On the day of purchase, the vehicle suffered a mechanical failure and had to be towed. While driving in my neighborhood with my children inside, the vehicle suddenly stopped moving and became stuck in reverse. A brand-new vehicle should not experience this type of failure. More recently, I experienced a dangerous steering event on the highway. While traveling in the left lane, the vehicle suddenly swerved into the right lane, then back to the left, and continued oscillating between lanes. The steering felt momentarily out of my control. If surrounding traffic had been heavier, this could have resulted in a serious collision. After inspection, the service department stated that no issue was found and offered no corrective action. Additional safety-related concerns include: The vehicle has unexpectedly stopped driving while in motion on multiple occasions. The steering system behaves unpredictably at times. The hybrid system has malfunctioned repeatedly, the vehicle has overheated and emitted a strong smoke odor. These repeated failures involving steering, powertrain, and hybrid systems raise serious safety concerns.Given the pattern of recalls, ongoing mechanical failures, and the inability of the service to diagnose or correct these issues, I believe this vehicle poses an ongoing safety hazard I respectfully request that NHTSA formally investigate these issues Kim

The vehicle was leaking coolant. The Mazda dealership Technician concluded it was a cracked radiator. There was no warning sign. Took vehicle in for an oil change and that's when the problem was discovered. Mazda completed service with replacing a new radiator on 2/12/26. On 2/15/26 the coolant is burning in/on engine. Reservoir is completely empty after being capped off during service. I believe the new radiator has cracked again. The vehicle didn't show a rise in temperature which would allow a driver to continue driving with this issue until they have a major engine failure due to lack of coolant in the system.

Premature failure of headlight assembly unit, (buzzing sound, known issue) completely unacceptable for this to happen right out of warranty. I don't think I will touch another Mazda in the future.
