2026 Mazda CX-30Recalls, problems, MPG & safety

“Abrupt acceleration while pushing the gas pedal, erratic tachometer. Stays at the same speed for a while when gas is pushed at highway speeds then accelerates abruptly. Vibration and noise during park. During highway driving, merging and passing got risky. Bought the brand new car on 7 September, immediately followed by these issues, got the car towed to the dealership on 10 September. Still in service who confirmed most of the issues were reproduced. No warnings in the console. Today is 16th. The last time I was contacted by the service was 11th. Was not given a timeline.”

“I am reporting a severe electrical fire and system failure hazard resulting from unauthorized, dealership-installed aftermarket wiring modifications on a brand new 2026 Mazda CX-30. ​At the point of sale, Walker's Renton Mazda ([XXX]) spliced invasive, unauthorized aftermarket tracking/security wiring (suspected LoJack or similar) directly into the factory CAN-bus and main wiring harnesses. These modifications were done without consent, actively concealed during the pre-purchase inspection, and compromise the integrity of the vehicle's primary electrical architecture. ​Specifically, the physical installation bypassed standard safety protocols and compromised the vehicle's firewall insulation. As a military electromechanical engineering veteran, I recognize that unauthorized taps into a modern vehicle's high-speed data network and main power lines introduce immense risk of short circuits, signal logic failure, parasitic draw, and most critically, catastrophic electrical fires. ​Despite providing physical evidence of the tampered wiring, the dealership's management has denied the modifications exist and refused to remediate the safety hazard by unwinding the…”

“The high beams would turn on by themselves, and no matter what I did, they wouldn't turn off. Each time the high beams turned on, I would have to fiddle with the control stick for a few minutes until the high beams turned off. Sometimes they would turn off for a second and then just turn back on. This is dangerous as it can blind other drivers. This has happened ever since I bought the car a few month ago. On August 11th the control stick broke off while I was trying to turn off the high beams. Now I have no control over the turn signals or the lights. I brought it to the dealer, but they refused to repair it for free. This is a brand new car which is under warranty.”
