Service bulletin 3241

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.

PIP57252020-06-15. Service bulletin. This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use.

The drivability concerns should not be single events but should be multiple occurrences associated with hot days.
