The 2018 Honda Civic is a passenger‑car built on the longstanding Civic platform and equipped with Honda’s standard 0W‑20 API‑rated engine oil, reflecting the model’s contemporary power‑train design. Across its production span from 1990 to 2022, the Civic has amassed 601 owner complaints for the 2018 year, with steering identified as the most frequent issue and four recalls recorded, a modest figure compared with the program’s peak of 1,402 complaints in 2006 and its low of 102 complaints in its inaugural year. This positioning indicates that the 2018 iteration sits in a middle ground of the model’s reliability record, offering a generally dependable platform while flagging steering as the primary area for attention.
