Honda issued software/warranty-extension campaigns for the same engine in the 2016-2018 Civic and 2017-2018 CR-V but never a formal Accord recall, Accord owners got software updates under TSBs and case-by-case goodwill. Practical defense: shorter oil-change intervals and watching the dipstick; engines rarely fail outright from it. Related Honda campaigns: TSB A18-124 family for 1.5T (Civic/CR-V warranty extension); no Accord-specific recall. Typical cost: $0 (software update / extra oil changes); engine damage claims are rare. 4 more issues are reported in other 2018-2022 years: Denso low-pressure fuel pump, stall/no-start (recall) (2018-2020); A/C condenser refrigerant leak, 10-year warranty extension (2018-2020); Infotainment freezes, ghost touches, and camera dropouts (2018-2019 (most complaints)); 12V battery drain / repeated dead batteries (2018-2019).
