Brake booster failure on other Traverse years

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

Should you keep driving it?

This page can't tell you that. 1 of 37 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.
