Mazda CX-5 electrical problems

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.

Blind spot monitoring system warning appears on dashboard of vehicle after driving for about 50-60 miles. This occurs only when I drive >50-60 miles in one trip without shutting off my vehicle. Speed does not matter. My sensors will not work until I turn off my car and turn it back on. This started as soon as I purchased my vehicle in July 2020. 1 previous owner (lease) before I purchased the vehicle. No prior accidents. Got the vehicle at ~30,000 miles. In January 2021, I drifted off the freeway and hit a tree going 35 mph during a snow storm. It was only myself (driver) and a passenger in the front seat at the time of the incident. Both were wearing seatbelts. The seat belts locked up, but airbags never deployed for myself or the adult passenger in the front seat. Driver sustained no injuries, but the passenger smashed their knee into the glove compartment and smacked their head on the window/seatbelt holder on the side of the interior wall. The passenger was asleep during the incident, which may have explained why they did not brace themselves. One minute we were on the freeway, then we hit a slippery spot, and within seconds we were head on with a tree. Drove away to avoid the possibility of any vehicles following my path and smashing into us. Car was still driveable somehow. Car was repaired after 3 weeks at Caliber Collision and looked great. Sensor issue persists still, but unrelated to accident. Mentioned it to Caliber Collision when vehicle was being repaired and they had a Mazda service person come out with a sensor machine and they could not find the issue.

Mazda has termed the issue Ghost Touch in their CX-3 models, which the NTSB issued a Technical Service Bulletin. It is dangerous as the infotainment system begins to switch between functions on its own, without driver or passenger input, and while the cars is in motion; changing radio stations, dialing phone numbers, turning the system display to Night Mode making it impossible to read while using the vehicle navigation system, exiting navigation maps altogether. The part number given to me by Mazda is K123611J0C. The dealer diagnosed and confirmed this issue in April 2022. They stated it is a common problem but it is not covered under warranty. Replacement costs quoted was over $1400, plus $180 to diagnose the problem.

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 contact owns a 2014 Mazda CX-5. The contact stated that while the vehicle was in park, the vehicle failed to turn off as intended. The contact continuously pressed the START/STOP button and brake pedal. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

My car won't shut off! I put it in park and turn it off and the accessories stay on. It is getting worse and worse and has taken up to 7 times of turning it off and on, backing it up and forward before it will just turn off for me. I get scared that it won't turn off. I found this forum online and it seems this is a very common problem that is not being addressed by Mazda. https://www.cargurus.com/Cars/Discussion-t49115_ds799849 Not being able to turn my car off is a very big safety risk for me and my 2 year old son.

The car battery does not get fully charged even after long trips and continuous use of the vehicle. It has been so ever since the vehicle was purchased brand new and maintained meticulously with all service performed on-time at the dealership. Even after long trips exceeding 350 miles, the battery would charge only up to 50% (12.2 volts) and never to 100% (12.7 volts). Thereafter it would quickly discharge to Low (<11.9 volts) if a few shorter trips were made. Upon bringing this to the dealer’s attention while the car was still under warranty, they ran a battery and alternator test and quickly dismissed the issue saying that both the battery and alternator were working fine. Nevertheless, in just two years the OEM battery failed from constantly being in a state of low charge, despite using the vehicle regularly for long trips. Because the dealer refused to honor the warranty, I had to replace with a new battery at my own cost. Now the new battery doesn’t charge beyond 50% (12.2v) either, and I have to routinely charge it every few days to full (12.7v) with an external battery charger just so the battery doesn’t die and either gets me stranded on the road (safety issue for myself and others) or damages computers/other electrical components (reliability and repair issue).
