Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While traveling approximately 70–80 mph on a heavily traveled interstate with significant commercial truck traffic, the vehicle suddenly stopped responding normally to accelerator input. I pressed the accelerator pedal fully multiple times, but the vehicle would not accelerate. I was traveling with my mother and young child and was able to safely move the vehicle to the shoulder. After shutting the vehicle off and restarting it, a high-voltage battery temperature warning briefly appeared on the instrument display for several seconds and then disappeared. …”

This occurred repeatedly since the vehicle was purchased. The dealer inspected the vehicle multiple times; on the first attempts they could not duplicate the issue. …”

NHTSA complaint #11772905, filed 2026-10, 300 miles“Instrument cluster will reboot during braking at random times. All warning lights turn on, gauges go to zero and front wipers are set off. This happens for 1-3 seconds. Mazda replaced instrument cluster but only made issue worsen they said it’s safe to drive but very distracting especially when turning onto busy roads. Currently being experienced by multiple other vehicles, so not isolated. Bought in February 2026 and started in early March 2026, currently still an issue as of June 2026.”
