Service bulletin Update Bulletin

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

UPDATE Technical Bulletin (ECM programming issues) Current ECM programming may cause poor engine idle quality while the air conditioning compressor is activated. If vehicle is equipped with an automatic transmission, TCM must be reprogrammed along with the ECM. If vehicle is equipped with a manual transmission, only ECM programming is required. Current ECM programming may be causing slight hesitation related concerns on vehicles equipped with 2.0 liter CBPA engines (depending on driving conditions). The production solution to this issue was optimized software to enhance engine idle quality while the air conditioning compressor is activated. Improved ECM/TCM software was also introduced to address drivability concerns and slight hesitation complaints.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
