   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.

   There is a consistent issue with the “ghost touch“ and the electrical system so when you’re going down the road, the musical will change. The music will blast up or down randomly it’ll get stuck and it’s very distracting. It will hang up on people while you’re having a conversation through the car phone. This was a recall for Mazda 2014 through 2016 and they need to extend it because it was still happening with my 2017. This is my first experience with Mazda and it has not been a good one as far as this goes. I do a lot of driving and phone calls and music are very important and stuff randomly changing or getting stuck while you’re driving and then trying to fix it is very dangerous.

   Infotainment system randomly makes its own selections. Turns volume up and down, changes settings, changes stations... etc. Anything that can be controlled on the screen is at risk of being randomly hijacked. Once, my drivers assist volume was unexpectedly turned to full blast and randomly shouted "navigation assistant will be at this volume. " I jumped so badly I actually could have crashed if I hadn't been at a light.

   The contact owns a 2017 Mazda CX-5. While driving the vehicle, the engine overheat warning suddenly illuminated on the dashboard cluster panel. The contact pulled over immediately, restarted the engine, and coasted the vehicle to a local, independent mechanic shop. The independent mechanic diagnosed the issue as a blown head gasket. For a secondary inspection, the vehicle was transported to an authorized Mazda dealership. Dealership technicians determined that the engine cylinder was actually cracked and recommended a full engine replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,000.

   Last week, the airbag warning light illuminated on my dashboard. Please be aware that this marks the fourth occurrence of this issue. Each time I bring the vehicle to the dealership, they provide a different explanation, and I am required to cover the repair costs. I have been informed that the vehicles were manufactured with a defect, causing the wiring harness to corrode at the junction where the temperature sensor connects to the engine, which measures the coolant temperature. Additionally, on two occasions, I was told that the wire had disconnected from the airbag connector. During my most recent visit to the dealership on 5/21/26, I was informed that an item in my glove compartment had dislodged the wire from the passenger side airbag module. This situation is extremely concerning, as it suggests that the wire can easily fall out or become loose from the airbag, given that there is no barrier between the glove compartment and the airbag. It is important to note that this issue arises each time I start the vehicle while it is stationary, and this vehicle has never been involved in an accident nor have the airbags been deployed.

   My car only has 65k miles on it and the rear differential failed and needs to be replaced. I am seeing this posted online by many Mazda CX-5 owners well under the mileage this typically happenes but out of the warranty period. Mazda should start a recall or compensate owners for this. its never been in an accident simply a commuter car used around town

   During a one-hour car ride, the front passenger side seat heater burned a hole through the seat, damaging my wife's skirt and leaving a hole in the upholstery. The overheating definitely originated within the seat. We immediately turned the seat heater off and have not used it since. It could have started a fire, which is very scary, or burned my wife, which is a serious safety risk. This issue has been mentioned by other Mazda owners, but I cannot find any recall reports. There were no warnings prior to the burning. The component is being taken to the dealership to be examined today.

   The infotainment system suffers from ghost touching. It has gotten out of control even after a “recall” fix at the dealership. Without being touched the volume changes, the stations change, the presets change, the car makes calls to my contacts. I am often unable to control the screen as it turns the car to max volume while driving. It is extremely unsafe, distracting and alarming.

12. Filed Nov 4, 2025Failure Jan 1, 2023Cranston, RIElectrical system

    The infotainment system in my 2017 Mazda CX-5 exhibits dangerous behavior consistent with known defects described in the Mazda Infotainment Class Action Settlement (Case No. 8:21-cv-01355). The infotainment system and touchscreen repeatedly activate critical functions on its own (“ghost touches”), sometimes going black, changing critical settings, disengaging phone calls as well as unexpectedly activating phone calls, and navigation features engage or freeze unpredictably. These malfunctions distract from safe vehicle operation, requiring driver attention to manage the malfunctioning display. The vehicle’s display is integrated with backup camera, audio, and Bluetooth controls, so these repeated malfunctions cause safety concerns while driving. Mazda and the dealership have refused to repair the defect under the Limited Warranty Extension established in the settlement, incorrectly claiming the issue is unrelated to the CMU (connectivity master unit). However, these symptoms are identical to those described in Mazda’s internal service bulletins (CSP13 and TSB 09-022/17) and covered by the settlement. I believe Mazda is failing to properly address a continuing safety-related defect that impacts infotainment stability and driver concentration. These issues have occurred for years and are continuing nearly every time I operate the vehicle.

    Rear differential failed around 97,000 miles. We were three months past our certified pre-owned warranty. Total cost to repair was around $4400 after a discount on parts and labor through our Costco membership. Contacted Mazda to see if they’d be willing to provide any assistance to cover the repair, they declined. Service advisor told us that it was a catastrophic failure that we did not cause. We purchased this car in 2020 and have always had it serviced at the dealership and at no point did they bring it up as it being an issue. The rear differential should not fail.

    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
