Service bulletin B111116

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

"N20 ENGINE OIL FEED LINE TO THE TURBOCHARGER: LIMITED WARRANTY EXTENSION TO 10 YEARS/120,000 MILES. When starting a cold engine, a ""plume of blue smoke"" can be seen emitting from the exhaust tailpipe for approximately 10-20 seconds. There is no engine malfunction light illuminated (no"" turbocharger boost faults are stored) and no drivability issues are detected. When the vehicle is parked overnight the engine oil pressure will equalize, this may cause engine oil to leak past the turbocharger ""exhaust side"" turbine seal."
