Service bulletin sb_2020_01

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

Any unauthorised modifications, including fitment of non-approved after-market air filter resulting in generation of diagnostic trouble codes (DTC’s) P0101 & P1109. We have had several instances where DTC’s P0101 & P1109 had been set and the car recovered into the dealer, only for them to find that the original equipment engine air intake filter had been substituted for a non-approved after-market type (applicable to both dry and oil coated types).

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
