Recall 23V732 covers 42,742 2019-2021 Mercedes-Benz cars and SUVs missing a rear brake-pad inspection gauge and instructions. Repair is free at any franchised Mercedes-Benz dealer.
Mercedes-Benz is recalling 42,742 2019-2021 A 220, Cla 250, Glb 250, Gla 250, and AMG models because they lack the inspection gauge and owner manual instructions needed to check rear brake-pad wear. Driving with worn rear brake pads can reduce braking ability and increase crash risk, so Mercedes-Benz dealers will add the gauge and instructions free of charge.

What's wrong?
The rear brake pads on the 2019-2021 Mercedes-Benz A 220, Cla 250, AMG A35, AMG CLA35, AMG CLA45, Glb 250, and Gla 250 are the friction pads that press against the rear brake rotors to help slow the vehicle. Mercedes-Benz supplies an inspection gauge for checking rear pad wear, plus owner's manual information that explains how to use it. The gauge does not stop the vehicle; it helps an owner or technician confirm pad thickness.
On affected vehicles, a documentation error in the production control system left the inspection gauge out and left the matching owner's manual instructions out. That creates a compliance problem with the light vehicle brake standard because the rear pad wear check tool and instructions are not available with the vehicle. Mercedes-Benz reported that front brake pads wear sooner, and the front axle has an electronic wear sensor that shows a brake-pad warning message.
There is no warning sign that the gauge or booklet is missing. The driver does not receive a warning from the vehicle for this issue.

What's the safety risk?
Worn brake pads reduce braking ability and increase the risk of a crash. There is no warning sign before this brake pad wear affects braking, so leave extra stopping room and schedule the dealer inspection soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2019-2021 Mercedes-Benz A 220, Cla 250, AMG A35, AMG CLA35, AMG CLA45, Glb 250, or Gla 250 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free inspection-gauge installation and supplemental owner's manual information so you can check rear brake pad wear correctly.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 23V732 when you call.
- Ask the dealer to confirm the rear brake pad inspection gauge is installed and the supplemental manual information is placed with your owner's materials.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking when traffic allows.
What happens at the repair
At the dealer, a Mercedes-Benz technician installs the inspection gauge needed to check rear brake pad wear and provides the supplemental owner's manual information for using that gauge. The replacement work and related labor are free under the recall. Out-of-pocket brake inspection repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain covered by warranty. Ask the service desk how warranty coverage applies to prior repair paperwork.
