Brake booster failure on other Pacifica years

No other Pacifica model year has enough reports of brake booster failure for a sheet of its own. See every Pacifica year.

What this problem usually is

This is the narrower sheet inside brakes for reports about a hard pedal or a failed power assist. The pedal stops feeling normal: it turns stiff, takes far more force, and the car needs a longer distance to stop.

What owners wrote

“The brake booster has failed, a hissing noise is audible coming from the brake pedal when depressed. I have also noticed reducing stopping power in certain situations. It appears this issues is referenced by Chrysler in an extended warranty, covered under Mopar Warranty Bulletin D-22-15, however this car has now been in service for 6 years.”

“Brakes hiss and won't slow the car down well. Issue is with the brake booster. The car creep forward or sometimes not stop in time. the peddle pushes back against you when depressing it.”

“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.
