What's wrong?
In Mercedes-Benz recall 22V125, the rear brake caliper is the clamp that holds the brake pads at each rear wheel. When you press the pedal, hydraulic pressure moves the caliper so the pads squeeze the brake rotor and slow the vehicle. The caliper housing fasteners hold that assembly in the correct position.
On certain 2020-2021 Mercedes-Benz Gla 250 and AMG CLA35 vehicles, supplier production left a batch of caliper housing screws below the required torque. A loose fastener lets the caliper housing shift instead of staying fixed. That movement can reduce brake performance, and in the worst source-described case, rear brake components can detach from the vehicle.
Before the issue becomes obvious, the driver can hear noise from the rear axle area. Once the condition is active, the instrument cluster can show a brake warning light or the message "BRAKE".

What's the safety risk?
Reduced braking performance increases crash risk, and loose rear brake components can detach and create a road hazard for other drivers. Listen for unusual noise from the rear axle and treat a brake warning message as a reason to slow down, stop safely, and arrange service. Repair is free at any franchised Mercedes-Benz dealer.

- Contact a franchised Mercedes-Benz dealer to schedule the free rear brake caliper fastener inspection and tightening, which fixes loose fasteners that reduce brake performance or let rear brake parts detach.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 22V125 when you call.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the rear brake caliper housing fasteners and tightens them if they are loose. The recall covers the inspection and labor at no cost. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how that warranty coverage applies if you have prior repair paperwork.
