Subaru is selling new vehicles with inadequate amounts of coolant in the engines cooling system. This has caused an immediate need for coolant being added as residual air in the system in expelled to the reservoir. If a customer follows subarus guidance for time/mileage to first inspection they risk having the car overheat/stall while driving potentially cause bodily and/or property damage.

I had pulled into our garage and had come to a stop. With my foot on the brake, I was reaching for the ignition button to turn the car off when the car suddenly accelerated forward and struck our large metal tool box, pushing it through the rear wall of the garage.
