What got replaced
Owners who name the part that was replaced mention the brake booster (24 reports).

“The vehicle's brake booster is going out. The vehicle's warranty was already extended once but is now out of that 5-year timeframe. This issue began about 2 weeks ago. Now, the brake pushes back and doesn't want to engage which poses the risk of rear-ending someone. Chrysler is aware of this situation and refuses to extend or fix the issue.”

“My breaks stopped worked due to a failed brake booster. I would compress the brake and it would let out air and not adequately stop. When it did finally stop, it would propel me forward. This became very dangerous for my family and I”

Should you keep driving it?
This page can't tell you that. 2 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
