Service bulletin B120116

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.

Under certain engine operating conditions the measured air mass between the cylinder banks 1-4 and 5-8 is miscalculated by the DME's. This could result in incorrect engine torque and mismatched ignition parameters with the possibility of internal engine damage.
