What Happened
The vacuum booster in your vehicle helps assist your brakes when you press the pedal. It's connected to a small air tank that's supposed to provide extra power. Unfortunately, some of these tanks might have been made incorrectly.
Risk if Unfixed
If the air tank leaks, you might hear a strange noise when you press the brakes, and over time, it could make your brake assist slower to respond. This could lead to a situation where you have to press the brake pedal harder to stop your vehicle, which could increase the chance of a crash.
Free Fix
Your Mitsubishi dealer will replace the faulty air tank with a new, improved one at no cost to you. You should schedule the repair as soon as possible and contact them if you haven't received the free fix within a reasonable time.
