Yes. NHTSA recall 22V199000 covers 2022 C-Class (W206) models where the rearview camera image may fail to appear or may appear late when reversing. This reduces rear visibility and increases the risk of backing into objects or people. The repair is covered under the recall, so there is no out-of-pocket cost.

The car may enter limp mode or show a 'Malfunction – 48V onboard electrical system' warning. After warranty, independent forum-reported replacements of the 48V auxiliary battery commonly fall in the $1,500-$2,500 range.
