2016 Mazda CX-5 Electrical System Problems

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.

I was driving down the road and started smelling smoke then looked over and my passenger seat was in flames.

Passenger side seat heater overheated and burned upholstery.

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.

The contact owns a 2016 Mazda CX-5. The contact stated that while driving 60 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. No warning light was illuminated. In addition, there was an abnormal rattling sound coming from the engine. The contact pulled over to the side of the road before the vehicle stalled. The vehicle failed to restart. The vehicle was towed to an independent mechanic who determined that the engine had failed due to a lack of maintenance. The contact stated that the vehicle was equipped with an automatic reminder regarding the oil change. The contact stated that the oil change reminder failed to illuminate to indicate that the oil level was extremely low. The check engine warning light also failed to illuminate. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

The info uni in the car constantly resets itself. It happens when GPS is activated, parking, listening to directions, pretty much at all time especially in crucial moments. Nav center doesn't even load at times, this causes unknown information of speed limits and streets.

Keyless entry stopped working, key fob battery replaced as well as car battery. Coolant issues. Heater core and sensors

We had another CX-5 in the back that we used to test whether or not it was either the throttle body or the BCM ( Body Control Module ) or the PCM ( Power Control Module ) not working that is causing your vehicle to not wanting to turn on The throttle body passed we transferred it over from vehicle A ( Being the donor ) to vehicle B (Being your vehicle ) and it was still doing the same thing which it would crank but not fully turn on and that is how we ruled that part out The BCM we also transferred over from vehicle A to vehicle B and same thing it would crank but not fully turn on This is what the mechanic at Mazda Collision Center of Irving stated: The PCM has power and is communicating with everything else in the vehicle. If it was the PCM then nothing would work and we wouldn't be able to even cycle the power as if we were going to turn on the vehicle We brought this over to our Mazda Foreman and we showed him the codes it was throwing and what was going on and explained everything and he did tell us that it could be the main harness that is causing all of this he is not for sure just because he is not the mechanic involved in this but he said that is a good start. I am uncertain exactly what is wrong with the vehicle. When I took it in to be serviced, it worked. The mechanic then said he couldn't work on it anymore after trying to fix the body work because the electrical system had failed. I then had it towed to Mazda to see if they could fix the issue. I had originally took it in because of a minor fender bender. I am unclear as to why it has taken four months and my car still doesn't work and I do not know how to afford buying a car to replace it when I cannot trade it in since we cannot resolve the electronic portion through insurance.

The engine light constantly appears along with the "Schedule Maintenance Soon" light. Taken to dealership many times within my 3 month warranty and no definite reason was given.The vehicle rides very bumpy though sway bar was inspected and supposedly repaired by dealership during my 3 month warranty.

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.

Ghost touch screen on multimedia. Causing detracting issues while driving.

The used 2016 Mazda CX5 I just bought apparently has the "ghost touch screen" where the Infotainment system will randomly pick controls, place phone calls, change navigation. How can this not be a safety recall? I'm afraid to drive this car and not have full control of the navigation system or controls. This is DANGEROUS to have this happen when driving!! Mazda should be held accountable for this clear safety problem.

This vehicle has rear Electric Parking Brakes. Some time it's works sometimes it doesn't release the rear passenger side breaks. The rear passenger side brakes make to much noise and brakes pads destroy rotor earlier then others. Mazda dealers doesn't says to much on that and ask for above $1000 repair to change faulty EPB clipper. But my research says many people have same complaints with this model by mazda built-in around 2016. This is safety issue, if I replace brake pads every 4 or 5 months it cost me money. If I don't I cost me my safety.

The contact owns a 2016 Mazda Mazda CX5. The contact stated that on two separate occasions, the vehicle unintentionally accelerated without warning in an attempt to park the vehicle. On the first occasion, the vehicle drove in between two trees with the contact's foot on the brake pedal before the vehicle came to a stop. The air bags did not deploy upon impact and no injuries were reported. The vehicle was towed to an independent body shop where the vehicle was repaired for minor damage. The contact was also informed that no computer codes indicated any signs of a mechanical failure. On the second occasion, the vehicle crashed into a parked vehicle while again attempting to park the vehicle in a parking lot. The force of the collision caused the already hit vehicle to crash into yet another parked vehicle. The air bags did not deploy upon impact and no injuries were reported. A police report was filed. The vehicle was towed back to the same independent mechanic where the code reader indicated that the vehicle had a low battery; however, the battery did not need to be replaced. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle remained in the possession of the independent mechanic and had yet to be repaired. The failure mileage was approximately 70,000

smart key. during driving all the lights on the dashboard come on and the siren goes off and unable to have it turn off. After a period of time, its wears down the battery and it is no longer drivable. First time, it was towed to the AAA auto repair and they could not find anything wrong with it. The 2nd and 3rd time, AAA towed it back to Maita Mazda where we purchased it in good faith less than two months ago, and their service department could not find anything wrong with the electrical system. They replaced the battery the seond time, and the issue still occurred again when I turned it off. Then turned it back on as I needed to close the driver side window, and it would not turn on. No one seems to believe me, and we cannot get Maita to take it back and give us another vehicle in its place. It is extemely dangerous to drive in traffic, and we only bought it because it has a big enough trunk for my spouse's walker, and later a wheel chair. It is paid for in full,

Last month, my vehicle suddenly applied the electronic parking brake (EPB) while I was driving. The EPB & related warning lights illuminated & would not release until the vehicle was turned off. After turning off the vehicle, the EPB motor could be heard applying the brake to the rear wheels. When the car was restarted, the EPB would remain off for a period of time but would then suddenly reapply. I took my vehicle to a Mazda dealer & they determined the calipers & EPB motor had failed due to my vehicle not being placed in service mode by the brake servicer. This explanation makes no sense because the brakes were replaced over a year ago (& not since) with thousands of miles being driven since then without this issue arising. I also conducted my own research & found that Mazda has issued at least 3 separate technical service bulletins (TSB) on this issue. The first two recommended replacement of the EPB switch & the third determined that defective calipers were the cause and should be replaced. I asked the dealer to save my calipers & confirmed that they are part of the defective batch noted in this TSB. I have contacted Mazda (including their legal counsel) & they are unwilling to provide any explanation or engage in any sort of investigation. As former legal counsel for an automotive company, I believe this presents a serious safety issue for consumers based upon the fact that a parking brake could randomly engage while driving & cause sudden loss of speed/control. Thankfully, this did not result in harm to my family, myself or others. I am certain that this issue is affecting others based on chatboard discussions I have found online related to this topic (which helped me find the TSB). I am concerned that Mazda may have attempted to undertake a silent recall via this TSB where in warranty customers are covered & out of warranty customers are given the 'service mode' explanation to justify their responsibility. This should have been handled as a recall by Mazda.

The Infotainment system engages in "ghost touch," where the screen scrolls through and clicks random buttons on its own. This occurs both while I am driving and while I am parked. It will change radio stations, exit out of the navigation, and click other random buttons so that I then have to turn off the display in order to get it to stop. For example, yesterday, it kept clicking the repeat button on the Bluetooth display so I was forced to listen to the same 1 second of a song until I could finally shut the Infotainment off. When this occurs while driving it is a hazardous distraction. Mazda had the same issue with its Infotainment system in the 2016 CX-3 and issued a recall. I reached out to Mazda to explain I am having the same problem but they will not fix it.

When the vehicle is running, but not moving the touch screen display randomly jumps/changes the display. This malfunction has changed the current radio station, navigation map screen, and/or the maintenance warnings/alerts. I believe this "ghost touch" poses a safety hazard not only due to the distracting beeps and screen changes but also the random change/reset of important maintenance alerts such as oil change and tire rotations. My Mazda dealer has updated the software but did not correct the malfunction. They now say I need to pay for a replacement of the touch screen display component to correct the "ghost touch" defect.

The electronic emergency brake switch freezes in cold weather . The parking brake can not be released until the weather warms. This is safety issue, because the motorists is now stranded. I took my vehicle to the dealership,. but the would not address the problem. This happened 2 times on the following dates 13 February 2019 14 February 2022. I'm retired and very little. I only have about 23000.miles on my vehicle. I live ln New York City and do not feel safe driving in the winter, because my vehicle's electronic emergency brake switch freezes in the cold weather .

FRONT PASSENGER SEAT CAUGHT FIRE WHEN SEAT WARMERS WERE ON. I WAS TRAVELLING IN A RURAL AREA IN ALASKA WHEN I HAD TO STOP BECAUSE MY PASSENGER CAUGHT FIRE ON HER JACKET.
