Service bulletin Dealer 96H5

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

In the event of a catalytic converter failure, which could negatively impact tailpipe emissions, existing diagnostics may not properly illuminate the check engine light (MIL) due to an error identified with Rear O2 Sensor monitoring. Additionally, under certain conditions it is possible that a diagnostic anomaly may occur during the initial drive cycle when coming to a stop, potentially causing the Start/Stop system to not operate as intended. In such a case the engine may go into limp mode, a condition where the vehicle can still be driven but with restricted RPM, accompanied by illumination of the check engine light (MIL).
