Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After driving >2000 miles or about a month, I could hear a loud, grunting/grinding noise when accelerating aggressively from 1st to 2nd gear when on EV or gas mode. Brought the vehicle at the dealership service department 4 times already, each time MAZDA Headquarters in California confirmed that this is a known and documented condition. According to Mazda, the grunt noise you’re hearing when the vehicle shifts from first to second gear under medium to aggressive throttle is considered normal operation. …”
NHTSA complaint #11690803, filed 2025-10“The day after purchase, with 216 miles on the odometer, a major failure of the hybrid electrical system occurred. The car immediately shut down, not allowing the car to be moved (it could not be shifted out of Park ). The message indicated that a high voltage leakage was detected and that the system was hazardous. It required a tow to the dealer. The dealer's service center cleared the error and refused to take further action. If this should happen again, on a busy street, serious injury could result.”
