Brake fluid leak on other E350 years

What this problem usually is
This is the narrower sheet inside brakes for reports of fluid loss: an empty reservoir, fluid at a wheel, or a brake line or hose that let go. The wider sheet covers brake complaints in general, and this one is for cars that lose the hydraulics themselves.
What got replaced
Owners who name the part that was replaced mention the brake line (35 reports).
Recalls and investigations
No recall on the brakes covers the 2014 model year as of Sep 29, 2026.

Should you keep driving it?
This page can't tell you that. 0 of 36 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.
