The 2018 Harley-Davidson FLHC has 2 recalls, both involving the rear shock absorber, where a broken mounting component can allow the shock adjuster to contact and damage the rear tire, causing a sudden loss of tire pressure and raising the risk of a crash.
Prior repair attempts did not fully resolve the issue: the first recall addressed a breaking mounting tab on the rear shock pre-load adjuster, and a subsequent recall identified that the fastener securing the shock absorber itself can also break, producing the same result. Owners should confirm with a dealer whether both remedies have been applied to their specific motorcycle.
