Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The engine suddenly stalled without any warning lights and the car went dead right after I exited the freeway. It was very scary. I pushed the start engine button and the car started and I continued my drive. I took the car to the dealer the next morning. I am currently waiting for a phone call from the dealer.”

NHTSA complaint #11023863, filed 2017-09, 18 miles

“Vehicle was inadvertantly turned off while in drive, when parking the vehicle no alarm sounded. Upon exiting the vehicle, the vehicle began to roll backwards, forcing me to jump back into the car and jam on the brake. One would think that as a safety measure, the car would be required to be in park, before turning off the engine. While its conceivable that in an emergency the driver may want to turn off the vehicle while in gear, this would be very rare, and could be accommodated by programing the off switch to require multiple pushes or holding in the button for an extended period. …”

“In February, 2022, my 2015 Mazda 3 experienced a major failure, while I was driving on a local road, going 35 miles per hour. All of a sudden, the engine lost power, three warning lights came on, and the car was struggling to go 20 miles per hour. Being near a friend's house, I drove there. From there, her husband followed me home. The next day, my car was towed to the Mazda dealership. The mechanic diagnosed the problem as “found TBS NUMBER: 01-014/16 and inspected coils found they were bad according to lot numbers”. He replaced all four engine coils and all four spark plugs. …”
