Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Was driving on interstate at night. Engine light came on and car immediately drove as if it were not operating on all cylinders. Took it to dealership and it had multiple misfire codes, 301, 351, 352, 354. I researched and found multiple complaints filed on-line regarding the exact misfire codes I experienced and PCM issues in this particular year, make and model. This problem is way too expensive to fix on a personal level. If Mazda is aware that this has been an issue, they need to remedy it. …”
NHTSA complaint #10615507, filed 2014-07, 113,000 miles“Coolant was leaking into my engine where the oil goes and I was unaware. The vehicle stalled in me while driving because of this. Even after figuring out what the issue was and trying to have it fix it became inoperable.”
