Engine Oil Leaks (Cam Tower Seals, Valve Covers)

Oil seeping or dripping from cam tower seals and valve cover gaskets is a well-documented issue, particularly on the 5.7L V8 engine. This can lead to a burning oil smell and, in severe cases, a fire risk. Early detection and repair are crucial. Estimated repair cost: $500 - $1500.

Secondary Air Injection (SAI) System Failure

Failures of the SAI pump and switching valves are common, often occurring around 75,000 miles. This system is critical for emissions during cold starts. Failures can lead to power loss, rough idling, and illuminated check engine lights. Estimated repair cost: $500 - $1500.

Some owners report vibrations or pulsations during braking, felt in the steering wheel or brake pedal. This can be due to warped rotors or other brake system issues. Estimated repair cost: $300 - $600.

Electrical System Issues

While less frequent than engine or steering issues, electrical system complaints do arise, including problems with sensors and control modules. Estimated repair cost: $100 - $500.
