2016 Mazda CX-5 electrical problems

Filed Oct 27, 2026 · Electrical, Visibility · WA

My windshield wipers stopped working completely. I am unable to see out my front window properly while its raining. Yes the dealership said that my front body control module needs to be replaced which is the same issue that other Mazdas from the same era have had safety recalls for (the federal safety agency campaign 19v272000). No it hasn't been inspected by anyone other than a Mazda dealership. The front wipers slowly stopped working. First the highest setting didn't work at all, then the wipers would work sporadically, and now they don't work at all.

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 federal safety agency investigate this matter and require Mazda to issue a recall or establish a repair program for affected vehicles.

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.

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.

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.

The front passenger seat heating system caught fire and burned through the fabric and my dog's seat. The fumes made me and my dog nauseous.I had to swerve across the highway and stop on the shoulder to extinguish the seat fire/burn. The fuse was pulled for safety. The seat is in storage for inspection. Mazda will be contacted.
