Air Bag Inflator Initiator Failure

Two recalls address potential failures in the seat-mounted side airbag inflator initiators. This could lead to non-deployment during a collision, posing a significant safety risk. Estimated repair cost: $0 (Recall).

The B58 engine, while generally robust, can develop oil leaks over time, often from the valve cover gasket or oil filter housing. These leaks can lead to oil consumption and potential fire hazards if not addressed. Estimated repair cost: $300 - $800.

Plastic components in the cooling system, such as the expansion tank or coolant hoses, can become brittle and crack over time, leading to coolant leaks. Overheating can damage the engine. Estimated repair cost: $400 - $1000.
