Electrical System owner reports: Mazda CX-5 years in the records

The records describe a possible crash, fire, injury, or loss of control.

“MY 2020 MAZDA CX-5 WAS 2 DAYS OLD AND THE BATTERY WAS COMPLETELY DRAINED AND HAD TO BE TOWED TO THE DEALER. I PICKED IT UP AND THEY DID NOTHING TO THE BATTERY. THEY TOLD ME NOTHING WAS WRONG AND THEY REPLACED THE KEY FOB BATTERY. TWO MORE DAYS AFTER THAT I PARKED IT IN MY GARAGE AND PUSHED THE BUTTON TO TURN IT OFF. APPARENTLY IT DID NOT TURN OFF AND COME MORNING, I HAD SIGNIFICANT CARBON MONOXIDE POISONING AND WAS HOSPITALIZED FOR 4 NIGHTS. MY CAR WOULD NOT START AGAIN AND THE ODD THING WAS THAT THE BATTERY WAS DRAINED AGAIN AND THERE WAS STILL GAS IN IT. MY LOCAL MAZDA DEALER REFUSES TO HELP ME AND I AM TRYING TO CONTACT MAZDA'S MAIN NUMBER.”

The records describe a possible crash, fire, injury, or loss of control.

“The infotainment display screen on my 2020 Mazda CX-5 has suffered a severe hardware failure resulting in un-commanded inputs, commonly known as "ghost touching." While driving at highway speeds, the touchscreen constantly registers phantom touches. It actively hijacks the vehicle's computer system and cuts out my Apple CarPlay connection during trips. This morning, the ghost touching randomly turned the Apple Maps navigation volume up to the absolute maximum level without warning. This intense, sudden noise causes driver shock and distraction while in motion, creating an immediate risk of a wreck. The vehicle currently has fewer than 29,000 miles.”

“The vehicle infotainment system including the touchscreen display and Connectivity Master Unit malfunctioned. The touchscreen operates without driver input, the system freezes or glitches, audio activates unexpectedly, and phone functions behave erratically. The vehicle and components are available for inspection upon request. While the vehicle was being driven, the system initiated actions without driver input including unintended phone calls including calls to 911, sudden unexpectedly loud radio or audio volume, screen freezing, and loss of navigation. These events caused driver distraction and a startle effect while the vehicle was in motion, increasing safety risk to vehicle occupants and others on the road. The issue is ongoing intermittent and reproducible during normal driving conditions. The vehicle was presented to an authorized dealer multiple times. A software update was performed in an attempt to correct the issue, but the condition continued. The dealer advised that replacement of infotainment components such as the CMU or display may be required. The vehicle has been inspected by an authorized dealer on multiple service visits. The issue was also reviewed by the manufacturer customer experience case management team which acknowledged understanding of the malfunction but declined repair assistance. No police or insurance inspections have occurred. No warning lights or messages appear before the malfunction. Symptoms occur without warning and include random touchscreen activation, system freezing or rebooting, unintended phone dialing, and unexpected loud audio. The issue began after purchase and has continued despite repair attempts. Similar infotainment malfunctions including ghost touch behavior, screen freezing or rebooting while driving, unintended audio behavior, and dialing issues have been documented in manufacturer service bulletins affecting comparable vehicles, indicating this issue is not isolated.”

“The Smart Brake Support system malfunctioned while driving. The vehicle began shaking and lost power, requiring excessive throttle to move. The car hesitates and may not accelerate normally, creating a dangerous situation in traffic. Warning lights appeared on the dashboard and the vehicle became unsafe to operate. The issue occurred shortly after purchase and was reproduced multiple times. The dealer inspected the vehicle but refused to provide a written diagnosis or repair timeline. The vehicle is unreliable and poses a risk of sudden loss of control or rear-end collision.”

The records describe a possible crash, fire, injury, or loss of control.

“I purchased this vehicle as a used car from a dealership. On my way home, the infotainment panel began to shout at top volume that this is the volume that navigation would be set at. The volume was so loud that it was startling, and it continued on until I had to pull over. I contacted the dealer, but they offered no assistance. The car continues to control itself at the panel ferning with the use of android auto so that you can't use your phone GPS for directions. The radio will control itself, changing stations, making loud beeps, and turning the volume up. There is no way to stop this feature because you can't turn the system completely off while the car is on. I can find no way to fix this on my own. I have tried resets, but have seen ample information about other people having this problem online. This does not seem to be an unknown problem and I don't know why there has not been issued a recall because it's very dangerous.”
