Honda responded with extended warranty, revised software, and new piston rings (from 2019). Turbo spools from 1,500 rpm, peak torque at 1,700–5,500 rpm — a wide powerband with no turbo lag. Shorten oil change interval to 7,500 km for short trips. Timing chain maintenance-free. Despite the oil dilution issue, long-lived when properly maintained.

Honda (2022). Warranty extended 6 years. No permanent mechanical fix — Honda recommends more frequent oil changes. from 30,000 km

  • !! Timing chain wear from neglected oil changes from 150,000 km

    The L15B turbo's timing chain can wear prematurely if oil change intervals are stretched or the lubricant is weakened by fuel dilution. Rattling on cold start is an early warning sign.

    Symptoms: Rattling or clattering from inside the engine on cold start, noise fades after warm-up
