Engine and Engine Cooling System Issues

Failures related to the engine cooling system, such as coolant leaks, thermostat failures, or water pump issues, can lead to overheating. This is particularly concerning given the engine's susceptibility to internal damage when overheated. Estimated repair cost: $500 - $2,500.

Powertrain Malfunctions

Issues with the transmission control module or other powertrain components can lead to erratic shifting, loss of power, or complete failure. Recalls have addressed transmission control modules. Estimated repair cost: $1,000 - $4,000+.

Electrical System Faults

While less frequent than engine issues, electrical system complaints can range from minor sensor malfunctions to issues affecting vehicle operation. This includes problems with forward collision avoidance systems. Estimated repair cost: $200 - $1,000.
