NHTSA Complaint #11666085 — 2015 HONDA FIT

I am the owner of a Honda Fit, and I am reporting a persistent and worsening issue that began during the winter of 2024. The vehicle produces a rattling noise during cold start-ups, which has become increasingly loud and frequent over time. This vehicle has only 89,646 miles, which is considered relatively low mileage for a modern engine to begin exhibiting such symptoms. This suggests that the issue is not due to normal wear and tear, but rather a premature mechanical defect. Based on my research and discussions with other Honda owners, this issue appears to be linked to a defective Variable Valve Timing Control (VTC) actuator, a problem that has been documented in other Honda models and addressed through Technical Service Bulletin 16-088. I am concerned that this is not merely a cosmetic or nuisance issue. The noise suggests a mechanical defect that could lead to premature engine wear or even total engine failure if left unaddressed. Given the number of similar complaints across various Honda models, I believe this may be a manufacturing defect that warrants further investigation. I respectfully request that Honda acknowledge this issue in the Honda Fit and take appropriate action, whether through a recall, extended warranty, or goodwill repair program. I am also submitting this report to the National Highway Traffic Safety Administration (NHTSA) for further review.
