   Rear subframe corrosion on this vehicle. I am in a winter road salt region, the materials used for this vehicle's subframe are not compatible with consistent driving in this region. Similar vehicles (not mine?) were subject to a recall for the front subframe, but nothing for the rear. This rear subframe issues caused multiple failures of virtually every component of the rear suspension - control arms, rear springs, etc. The repair cost for JUST the subframe was $3813. Not repairing it was not an option - the vehicle had failed mandatory State of Maine inspection (a safety thing, if I'm not mistaken). This should be a Mazda problem, not a me problem. I contacted Mazda USA about this issue and got no response.

   Repeated Failure and Rebooting of Mazda Connect Infotainment System I am the owner of a 2016 Mazda CX-5. The factory Mazda Connect infotainment system has developed a recurring defect in which the system repeatedly reboots to the Mazda logo while driving. Prior to complete failure, the navigation system became intermittent and Bluetooth connectivity frequently disconnected, requiring repeated attempts to reconnect devices. The system now continuously cycles through the startup screen, making navigation, hands-free phone functions, and system settings inaccessible. These repeated reboots occur while the vehicle is in motion and are distracting to the driver. The flashing and rebooting screen repeatedly draws the driver's attention away from the road and interferes with the use of navigation and hands-free communication features that are intended to promote safe driving. After researching this issue, I found numerous reports from other Mazda owners experiencing the same symptoms involving the Mazda Connect system, navigation SD card, and Connectivity Master Unit (CMU). The frequency and similarity of these reports suggest that this is a widespread and well-known defect rather than an isolated incident. Because this defect affects driver attention and the safe operation of the vehicle's communication and navigation functions, I respectfully request that Mazda and the National Highway Traffic Safety Administration investigate this matter and require Mazda to issue a recall or establish a repair program for affected vehicles.

   (I am the owner of the car and am filling this out for my daughter who was driving it at the time, I was not with her during the incident) While driving down the road in the rain the wipers just stopped working. I have not had any dealers ID the specific problem yet. We replaced the wiper 20amp fuse and it did not fix the problem. There were no warning lamps and there are still no warning lamps. My safety was put into danger when I could not see out the window. I was nearly at work so I waited for the rain to slow down some was able to make it to work. The rain cleared while I was at work and it has not rained since. It is available for inspection upon request.

   Any time the vehicle has been sitting with the engine off and has been given enough time to “cool down”, upon starting the vehicle and switching from PARK to DRIVE, the vehicle will violently lurch forward while attempting to reach 2nd gear. This is dangerous behavior that is not normal for any vehicle. There is clearly something wrong with either the transmission or the way the software communicates with the transmission. When the engine is within normal temperature it doesn’t display this dangerous behavior. A similar TSB was issued for the 2nd generation of CX5s but not for this generation of CX5s

    I was slowly turning left into an alley when I heard a loud noise, the front of my car dropped, and the car immediately stopped and was immovable. Upon getting out of the car, it appears some joint separated from the wheel.

    My wife was driving our 2016 Mazda CX-5, and was getting ready to pull into our daughters' driveway. My wife slowed down to a stop before entering the driveway. She gave the vehicle some gas to move forward. She stated that there was a pause, then the vehicle accelerated forward slamming into the garage door and the corner of the garage/house. There was also a Tesla parked inside the garage that was knocked back about a foot and a half. The distance from the edge of driveway and street to the garage door is about 27 feet. This happened at 1:30 PM. The weather conditions were great, sunny and dry. Thankfully, no one was hurt. If my wife was another foot to the right, she would have hit the support post for the upper balcony, and there would have been a good chance of the balcony falling on top of her. Or, if someone was standing in front of my wife when she entered the driveway, they could have seriously been hurt! There were no warning lights on prior to the accident. This happened last Sunday, April 19, 2026. We had the car towed to a local body shop on the same day as the accident. The vehicle was towed away the very next day to our insurance company's salvage lot in Bakersfield. I do have all the information, address and phone number, of the lot where our car was towed to. Hopefully, the car can still be inspected by the proper authorities. Thank you for your time!

    Vehicle was taken to an authorized Mazda dealership for 60,000-mile service; coolant system drained and refilled. Immediately after service, check engine light illuminated (P011A – engine coolant temperature sensor correlation issue). Dealership retained vehicle, drove ~300 miles, performed a second coolant flush; issue persisted. Dealer determined heater core clogged, attributed to coolant contamination/corrosion introduced during service. Another CX-5 at the same dealership experienced the same issue. Safety Concerns: Heater and coolant system failure may affect cabin comfort and engine temperature monitoring. Occurred immediately after authorized service, suggesting procedural or system-related defect. Noted in Mazda Technical Service Bulletin 07-007/19 as a known issue. Attempts at Resolution: Mazda offered partial goodwill assistance (~$775–$875) and assigned partial responsibility to the customer. Multiple attempts to escalate with Mazda Customer Experience (Case manager Betty) have not resulted in a satisfactory resolution. Dublin Mazda dealership service department, Mr. Frank Gozales (866-502-9912) mentioned original coolant by Mazda has caused this issue on 2016, and 2017 Mazda CX5 and is Mazda problem. I am requesting NHTSA review of this issue for potential defect or safety investigation.

    My screen begins to change the display without me touching it. It has interrupted my GPS directions, causing me to get lost. It has gotten worse over time, now causing my back up camera to either not display at all or become partially blocked by another application randomly starting on the screen. My emergency brake lights flash on my dash, and auto technicians tell me it is a malfunction with the electrical system, not something in my brake system that needs to be replaced. We have tried that. These problems I have been told are not the responsibility of the manufacturer. I don’t understand why. It is distracting, alarming, and because it is getting more frequent with more systems being affected, it puts the driver in danger. This is not due to wear and tear - it is due to a faulty electrical program.

    Airbag light is flashing. Independent shop found code B00C1:93-8B. OCS Sensor B. Shop sent owner to dealer for inspection & repair. Charged $57.24. Dealer found DTC B00C1 passenger seat occupant classification sensor b. Replacement cost for the part $1,110.13, plus shop fess and tax for a total repair cost of this critical safety item would be $1,197.29. I did not have this service performed due to the high price. This safety item should be covered by the manufacturer. I recently learned that a dealer may not sell a car with this safety issue so I want it fixed and covered by Mazda.

    I noticed smoke filling the inside of my car. I looked over at the passenger seat, and my coat was on fire. I poured my drink on it, pulled over, and threw the coat out of the car. I saw a large hole in the lumbar area of the passenger seat, and it was glowing red and putting out a lot of heat. The seat heater was on, so I immediately turned it off. It was obvious that the fire has started inside the seat, and there was no other fire source in car--ie. lit cigarette, lighter, etc. If someone had been sitting there, they would have serious burns. The seat will need to be replaced.

    With no prior warning, just after turning into driveway, my car got stuck and would not move. It gave clicking sounds and would not move no matter which gear it was in. The towing service person needed a dolly in order to safely lift the vehicle onto the towing bed because the front, driver’s side tire would not move and was pushing into the fender. So far, the control arm and axel are completely separated from the car. Further investigation is ongoing to determine the extent of the spontaneous injury. This all happened without warning.
