The 2019 Mercedes-Benz C Class has 5 recalls, the most serious being an oil leak on certain four-cylinder models where turbocharger lines can drip oil onto hot engine components, creating a fire risk.
On the brake and stability side, two related issues affect certain vehicles: the electronic stability control software may not function correctly in some driving situations, and on C 300 and AMG C 43 trims, a separate software problem can either prevent the electronic parking brake from releasing, or allow the car to move only with stability control disabled. Both conditions raise the risk of losing control. There is also a concern with the emergency call system, where the communications module can become deactivated, meaning the system may not connect to emergency services after a crash or when the SOS button is pressed. The fifth recall involves an airbag warning label on the passenger sun visor that may be printed in the wrong language, which could cause confusion about airbag safety precautions.
