Brake booster failure on other Dart years

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

“I have a problem with my brakes and I took it to a shop. The mechanic told me I had oil in my vacuum line to the break booster causing it to fail. The 2013 and 2014 models of my car has a recall for this problem but the 2015 was not included.”

“Brake Booster failed, no ABS, no traction control, no electronic braking assist. I've read where this has been recalled in Darts in 2013 models. Master Cylinder and Vacuum pump may also be bad.”

Should you keep driving it?

This page can't tell you that. 2 of 30 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.
