The bonding between the glass panel and the sliding roof frame may deteriorate, possibly causing the glass panel to detach from the vehicle.
A detached glass panel can separate from the vehicle and become a road hazard, posing a crash risk.
What to do
MBUSA will notify owners, and dealers will inspect the glass panel bonding and replace the sliding roof -- as necessary -- free of charge.
The recall is expected to begin May 14, 2021.
Owners may contact MBUSA customer service at (800) 367-6372.
