Service bulletin TSB 25-2146

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 article supersedes 23-2132 to update the labor times from M-time to M-Time with a limit. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * "Exhaust Mode Selection Not Available" messages * Illuminated malfunction indicator lamp (MIL) with diagnostics trouble codes (DTCs) P26C5, P26C6, P26FE, P2BF9, P2BFB, P26C7, P2BF5, P2BF8, P2BFD and/or P2BFA. This may be due to an improperly seated exhaust system.
