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.
What got replaced
Owners who name the part that was replaced mention the master cylinder (14 reports) and the brake booster (3 reports).
Recalls and investigations
No recall on the brakes covers the 2025 model year as of Sep 29, 2026.

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.
