Differential Actuator Failure

The center differential actuator, responsible for managing the 4WD system, can fail. This may result in loss of 4WD functionality or warning lights. Estimated repair cost: $1500 - $2500.

Fuel Pump Module Corrosion

Corrosion can affect the fuel pump module, particularly in areas with road salt. This can lead to intermittent fuel delivery issues or a complete failure. Estimated repair cost: $600 - $900.
