Technical Service Bulletin 07-109-16 — 2015 SUBARU BRZ

This bulletin provides a procedure to address a hard starting condition which may occur on vehicles repeatedly driven for short distances. For example: This condition could arise while the vehicle is in inventory for an extended period of time, regularly started, moved around the lot then shut off before the engine comes up to full operating temperature. This type of repeated, short trip driving can cause carbon deposits to accumulate on the spark plugs and over time, the hard start condition to develop. This condition may take 60 or more similar ?cycles? as described above to manifest so, by description alone, it would be very rare for this to happen and quite challenging to duplicate.
