NHTSA Complaint #11541020 — 2015 HONDA FIT

Over last 2-3 years (50-70k miles), intermittent but now more consistent and loud grinding sound that lasts <1 second after push to start. Only occurs typically on a cold start (after engine has been sitting >12 hours, typically in garaged/cooler ambient temperature). Otherwise no issues with performance, no error messages. This is a known issue with VTC actuator (Honda released TSB 16-088) for this. I was told by the dealer that this can lead to catastrophic failure with the engine as it relates to the timing belt and the drivetrain. I was quoted $2100 for this repair. If it is true that there is a known defect that can lead to catastrophic failure, this should be covered by an extended warranty or recall.
