2016 MAZDA CX-5 Complaints

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.

The contact owns a 2016 Mazda CX-5. The contact stated while driving at an undisclosed speed, the electric parking brake module warning light was illuminated and the "Brake failure. Vehicle unsafe to drive," message was displayed on the instrument panel. The vehicle was taken back to the residence. The failure occurred on several different occasions. The contact expressed concern that the brakes could engage while the vehicle was in motion. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 84,000.

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.

The vehicle was taken to a local dealer to be diagnosed; however, the cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was made aware of the failure by the local dealer. The failure mileage was approximately 91,000.

In 2024 I started having problems with my battery replaced it 3 times last time with a Mazda battery per Mazda advice. The car started to jerk while driving took it back to Mazda said it could be fuel injectors. They cleaned them and problem persists. Took it back they cleaned purve valve and then I broke down while leaving on [XXX] . Called service dept called police since it was in the middle of the blvd. And in traffic. We were lucky no one hit us. They took my car gave me a loaner had it for 10 days. Couldn’t find any problems. Then in 4/2025 it completely died at my home I called Mazda they were able to jump the battery and had it for a month. Couldn’t find any problem. And now we are in 5/2026 my car was in my drive without out being driven for 3 days and now is dead once again. But it is so dead that I cannot open with fob and dash board is black.

(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.
