Recalls and investigations
4 recalls on the brakes cover the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.

The amount of vacuum created by the vacuum pump may decrease over time.
The brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative.
On the affected vehicles, the brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative.

Should you keep driving it?
This page can't tell you that. 2 of 29 reports involved a crash and 1 people were hurt. 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.
