A critical recall (15V019000) addressed potential fuel leaks from the fuel injection system's fuel rail. These leaks pose a significant fire risk. Estimated repair cost: $500 - $1,500.

Some 4.2L V8 engines can exhibit higher than normal oil consumption, potentially due to worn piston rings or valve stem seals. This is not uncommon for high-performance naturally aspirated engines. Estimated repair cost: $1,000 - $3,000+.

The V8 engine's cooling system, with its complex routing and multiple potential leak points (hoses, water pump, thermostat housing), can develop leaks over time. Estimated repair cost: $400 - $1,200.
