What Happened
The hydraulic control unit in your Ram is a crucial part that helps control your brakes, stability, and traction. It's like the brain of your brake system, and in some 2017-2018 models, it can fail without warning.
Risk if Unfixed
If the hydraulic control unit fails, you could lose your anti-lock brakes, electronic stability control, or traction control. This means you might not be able to stop as quickly or steer safely, which could increase the risk of a crash.
Free Fix
Your Chrysler dealer will replace the faulty brake control unit or its motor with a new one, completely free of charge. You should schedule the repair as soon as you receive the recall notice, and contact FCA customer service at 1-800-853-1403 if you have any questions.
