Yes. NHTSA recall 21V819 affects 2021 S500 4Matic, S580 4Matic, and Maybach S580 4Matic models, where a fuel pump defect can cause sudden engine stall while driving and may prevent restart. Check the VIN on NHTSA's recall lookup for a completed 21V819 repair and ask for the dealer receipt; during a cold start listen for the fuel pump prime and watch for any stall or power loss during the test drive. The consequence is a higher crash risk if the car stalls in traffic. The dealer recall fix is free, while an independent fuel pump replacement is commonly around $2,000.
Yes. NHTSA recall 21V939 covers 2021-2022 S-Class sedans, including S500 4Matic, S580 4Matic, and Maybach S580 variants, where a rear brake line can chafe and leak fluid. Check that recall 21V939 is completed, inspect the rear brake lines for abrasion or wetness, and watch for the low brake fluid warning, a soft or long pedal, or visible fluid near the rear wheels. The consequence is reduced braking performance and increased stopping distance, which raises crash risk. The authorized dealer repair is free.
