Service bulletin PIP4765A

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

This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that may have Service Engine Soon Malfunction Indicator Lamp on and a constant engine misfire. If Service Information diagnosis isolates no compression on the misfiring cylinder(s) with 100% leakage into the crankcase, perform the following steps as necessary before disassembling the engine. Technician will use a lighted bore scope if available to inspect the top of the related piston(s) through the spark plug hole to determine if any of the pistons are melted. If damaged piston(s) are found inspect for aftermarket parts. Also use the latest version of 09-06-04-026 to verify if there are aftermarket calibrations in the Engine Control Module. Take photos and document accordingly if anything is found.

On a level surface if the vehicle is launched from a stop at light throttle (less than 15%), then the throttle is closed before reaching 16 km/h (10 mph), then the throttle is opened and held to less than 15%, there could be a 1-2 upshift delay. This delay will last until the vehicle exceeds 24 km/h (15 mph) or the driver drops back to closed throttle.
