The 2021 MERCEDES-BENZ CLA 250 has 1 complaint and 214 recalls filed with NHTSA. The complaint involves a water leak due to improper sealing around the driver side rear light. Owners most frequently report water intrusion in the rear lamp assembly.
Common Issues- Water leakage. The seal around the driver side rear light is improperly installed, allowing water to enter the lamp housing and cause precipitation inside the light.
There are 214 recalls affecting multiple systems on the 2021 CLA 250. The majority relate to communication and electrical system software defects impacting the emergency call system and multimedia display, as well as child seat anchoring issues and rearview camera malfunctions.
Recalls- Communication Module Software. NHTSA recall 22V365000 affects 242,722 vehicles including the 2021 CLA 250. The SIM card software error disables the emergency call (eCall) system, preventing occupants from contacting emergency services in a crash. The risk includes delayed emergency response and potential injury. Fix involves an over-the-air update or dealer software update at no cost.
- Multimedia System Software. NHTSA recall 21V354000 applies to 343,191 vehicles including 2021 CLA 250 models. The MBUX multimedia software can cause a black display or reboot after startup, disabling the rearview camera image. This compromises rear visibility and increases crash risk. Dealers will update the software free of charge or provide an OTA update.
- Child Seat Anchoring System. Recall 21V034000 covers 231 vehicles including the 2021 CLA 250. The right-side ISOFIX anchoring bar may be missing from the right-rear seat bracket. This failure prevents proper child restraint securing, raising the risk of injury. Dealers will inspect and replace the bracket if needed at no charge.
- Emergency Call Location Software. Recall 21V058000 applies to 1,292,258 vehicles including the 2021 CLA 250. The communication module software may fail to send correct vehicle location during emergencies. Incorrect positioning delays emergency responders and increases injury risk.
