Fuel Pump Module Failure

The fuel pump module can fail due to electrical contact issues, leading to intermittent or complete loss of fuel delivery. This was a subject of a critical recall. Estimated repair cost: $600 - $1,000.

Electric Auxiliary Water Pump Failure

The electric auxiliary water pump, crucial for engine and turbocharger cooling, can fail due to component defects. This failure can lead to critical engine overheating and was also addressed by a recall. Estimated repair cost: $700 - $1,200.

While not directly tied to recalls, the twin-turbocharged V8 can develop issues with turbochargers, including wastegate problems or bearing wear, especially with higher mileage or inadequate maintenance. Estimated repair cost: $1,500 - $3,000+.
