Electrical System Malfunctions

Owners report a range of electrical issues, including intermittent headlight failures, power loss, and system shutdowns. These can be attributed to faulty wiring, module failures, or battery issues. Recalls have also targeted the brake light switch, affecting other electrical systems. Estimated repair cost: $200 - $1,000.

Vehicle Speed Control / Unintended Acceleration

A significant number of complaints involve unintended acceleration, sudden surges in speed, and difficulty decelerating or stopping. While specific component failures are not always detailed, this points to potential issues with throttle control systems, electronic throttle bodies, or related sensors. Estimated repair cost: $300 - $1,500.

Engine Issues (Stalling, Power Loss)

Some owners report engine stalling or noticeable power loss. This can stem from various causes including fuel delivery problems, ignition system faults, or sensor failures. The 4.6L V8 engine requires premium fuel, and using lower octane can lead to performance issues. Estimated repair cost: $400 - $2,000.
