Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 255 complaints with NHTSA since 2015. 40 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
I purchased a new Honda Fit in 2018. In November 2019, at 31,000 miles several indicator lights came on. The check engine, TPMS, Vehicle Stability assist, Electric Power System. The car was running smoothly but I was told by a Honda dealer there was excessive carbon build up. The cost to clean it out would be $500.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Which vehicles does ABOM06022023906 cover?
