MAZDA Complaints

My vehicle is part of Mazda's 2021-2022 Mazda Valve Stem Seal Settlement. The dealership had yet to call me in for the repair of said valve seal repair as I was on a list. The settlement is suppose to extend out the powertrain warranty on the vehicle 2 years/24,000 to 7 years/84,000. My vehicle has 60,083 miles on it. One of the cylinders on my vehicle lost compression. The dealership and Mazda both say they will not cover the cost for repair as they only are covering things in the powertrain relate to oil consumption. The cylinders are part of the powertrain and carbon buildup from excessive oil burning because of the defective seal causes valve damage or sticking which will cause compression loss. Mazda is actively denying what they agreed to in the settlement and costing people money for repairs that should be covered.

Rear differential began to leak. Mechanics (3) looked at the part and discovered play in both right and left side axles leading into rear differential along with loud clanking noises inside the differential itself. Seal areas on both sides of unit had extensive play. Diagnosed with worn gears inside rear differential. Vehicle is only 8 years old (bought brand new) and has 74,110 miles. Complaint filed with Mazda claiming that gears and rear differential should not have failed given the mileage. Mazda has advised me that the car was out of warranty (5yrs/60k mileage) that the repairs were not covered. They wanted me to drive my car to a local Mazda dealer but I declined since driving it may/would have caused more damage to differential. Advised them to have their mechanic go to my local repair facility where part was replaced and pick up the differential for verification. Research online has indicated other owners has suffered identical issues. Have not heard anything back from Mazda. Total cost to replace $3,993.49

The vehicle's touch screen for radio/nav/vehicle settings has delaminated which causes the display to detect "touches" that are a result of the delamination. This can result in navigation exiting, radio changing audio levels, and a myriad of other things like turning on/off vehicle safety settings. This was a known issue on the previous models and a short web-search has found that many others with this generation mazda has the same issue.

The touch screen infotainment system has the well known “Ghost Touch.” While I am driving, the touch screen can at random, activate buttons, make phone calls, change navigation systems, and activate any other features through the display. It can at times create an extremely dangerous situation while I am driving because the drivers attention is suddenly and at random being taken from the road. This happens with increasing frequency and there is no way to deactivate the touch screen. Mazda is aware that this issue is widespread and has done nothing about it, leaving it up to drivers to decide if they want to shell out hundreds of dollars to have the issue fixed or continue driving the vehicle under dangerous situations.

The contact rented a 2024 Mazda CX-50. The contact stated that while driving on a main street at 5 MPH, the contact attempted to slow down the vehicle by depressing the brake pedal, and in the process, the brakes locked and the vehicle proceeded to accelerate without the contact's consent. The contact was involved in a front-end collision with the vehicle in front of them. No property damage was reported. The vehicle came to a stop upon impact. The vehicle was towed back to the Enterprise rental center, where the vehicle was originally rented. The airbags did not deploy. No warning lights were illuminated. A police report was not filed. The vehicle was not destroyed. Three people were reported to be injured: the contact seated in the driver's seat, the contact's coworker seated in the front passenger seat, and the contact's wife seated in the rear passenger seat. No injuries were reported outside of the contact's vehicle. The contact sustained injuries to his shoulders and lower back, and the contact's wife sustained injuries to her neck and back; the contact's coworker's injuries were unknown. Medical treatment was not needed for the injuries. The local dealer was not contacted, and the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate mileage at failure was 26,839.

Car “died” while idling at a traffic light. It started but would not start several hours later and car was towed to mechanic. Diagnostics “determined “after several days that car needed an ECM. ECM was ordered and replaced, along with the battery. This took several weeks, in the meantime, I had to rent a vehicle. Vehicle picked up on May 29th and driven 250 miles and car sputtered, hesitated, slowing down in heavy traffic at high speeds on highway, putting other drivers and myself in a very unsafe situation. Several days later this happened again while traveling back home, again, at highway speed putting other drivers and myself in high risk situation. (This happened several times during both trips.) As I was focused on the road, I did not see if any messages were displayed. After returning home, the mechanic was informed via voice mail and again via telephone. The following morning (June 2), the car sputtered, hesitated to accelerate at low speeds and died while driving to repair shop (battery indicator illuminated as I was pulling over). Car has been towed again to repair shop.

While driving on a 75 degree and sunny day my Sunroof exploded. There were no cars around that could have thrown debris up. Luckily I had the shade cover closed or I would have been showered with broken glass.

I’ve been experiencing power loss and surges/RPMs drop for nearly a month now while driving at various speeds. Each time, the iStop indicator comes on. This is a serious safety concern. I am extremely worried that the vehicle could stall, especially while my family is in the car, while driving on a busy highway. Undoubtedly, this issue presents a significant risk to the safety of drivers and passengers. I am requesting your assistance in initiating an official recall from the manufacturer for this component failure. Based on my research, I am not the only one experiencing this grave issue. Many others have reported similar problems on forums like Reddit, which is proof that this is a widespread issue.

Issue with the engine cylinder head leaking engine oil from the side of the cylinder head, where the casting has a defect. Leaks engine oil onto the flashing for the exhaust and exhaust manifold, where it could catch fire. The problem has been confirmed and diagnosed by a licensed mechanic. However, the dealer would not take responsibility for repair or assistance in repair. There are no warnings, while driving and after stopping, the smell of burning oil comes into the car and also smoke from the engine compartment.

- Serious safety issue: car stopped suddenly in the middle of traffic - Errors appeared: Hybrid System Malfunction, “vehicle can not be driven” and “Electrical Leakage in Hybrid System Detected” - Would not come out of park, had to be towed to Mazda dealership - Picked up car and after 15 min of driving the 'hybrid malfunction' light came back on - Car was returned to Mazda dealership for testing
