Replace when it fails or shows intermittent failure symptoms. Unlike many parts, starters often give warning signs before complete failure.
Ford F-150 starters (2011-2017) with auto start/stop cycle much more frequently and may wear out sooner — around 80,000-100,000 miles.
Some luxury cars have starters in difficult-to-access locations (behind the engine, under the intake manifold), increasing labor costs significantly.
