Overview
| MLIT filing number | 1104152 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | May 27, 1993 |
| Manufacturer(s) | Mazda |
| Component | Supercharger |
| Production period | November 1991 — March 1993 |
| Vehicles affected | 14,726 units |
Defect
On vehicles equipped with a diesel engine, the heat shield plug protecting the bearing that supports the rotor of the pressure wave supercharger (PWS) from exhaust gases has insufficient strength. The heat shield plug may fracture. Continued use may cause insufficient lubrication, leading to bearing seizure, rotor lockup, loss of air supply to the combustion chamber, engine stall, and inability to restart.
Corrective action
On all vehicles, verify the supercharger serial number. If the vehicle is within the affected range, replace the supercharger with the corrected part.
