The C5 RS6 is renowned for its exhilarating performance, yet it is crucial to be aware of its common issues. The 4.2L twin-turbo V8, engineered in collaboration with Cosworth, is prone to timing-chain and tensioner failures, necessitating an engine-out service typically ranging from $5,000 to $15,000. Turbocharger wear is also a concern, often requiring a rebuild at costs between $2,500 to $4,500 per side.
