Vehicles Affected: Approximately 9,000 model-year 2018 Mercedes-Benz GLE350 and GLE350 4Matic, GLS450 4Matic and GLS550 4Matic SUVs, and model-year 2018 Mercedes-AMG GLE43 4Matic, GLE63 4Matic, GLE63S 4Matic and GLS63 4Matic SUVs
The Problem: The rear brake caliper pistons may not have been correctly coated, causing gas to become temporarily released into the rear brake hydraulic circuit, reducing braking performance and increasing the risk of a crash.
The Fix: Dealers will bleed the rear axle brake system for free.
What Owners Should Do: Mercedes-Benz will begin notifying owners in early September. Owners can call the automaker at 800-367-6372, the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more.
