EXPIRED BRAKE FLUID DANGER

Hi, I'm Bogi, one of the auto experts on RepairPal's Car Genius team! Great question, and I’m really glad you asked before doing anything! I would strongly advise against using old or expired brake fluid in your 2022 Subaru Impreza. Brake fluid is hygroscopic, meaning it absorbs moisture over time, and expired fluid can have a significantly lower boiling point than fresh fluid. In a modern vehicle with an ABS system, this can cause all kinds of problems including reduced braking performance, corrosion of sensitive ABS components, and in a worst case scenario, brake failure. On top of that, a completely empty brake fluid reservoir is a serious safety concern on its own. If the fluid has leaked out entirely, simply topping it off without finding and fixing the source of the leak won't solve the problem. This is a sealed system, so having no fluid is a sign that there is something wrong that should be checked out and resolved before the vehicle is safe to drive. Given that this is a relatively new vehicle and involves your braking system, I'd absolutely recommend going back to your ASE certified repair shop rather than attempting any fixes at home. This is really not something you want to take any chances with. Your brakes are the single most important safety system on your car!
