Filing in context
The Computer (Engine) is the most frequently cited component category in this archive, appearing in 49 of its 4,890 filings. This filing is one of 27 Mazda notifications from 2017 in this archive. For scale, 295 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 5 years.
Defect
In the diesel engine, over-speed control is incorrect. During full-throttle operation and similar conditions, oil contained in blow-by gas within the intake path may combust inside the combustion chamber, causing engine speed to rise uncontrollably. This leads to insufficient engine lubrication and seizure, and in the worst case, engine damage.
Corrective action
On all vehicles, reprogram the control software with the corrected software.
