The 2016 Mercedes-Benz AMG C63S has 3 recalls, the most serious being two safety-critical issues: a steering rack defect that can leave the car unable to be properly steered, and a driver airbag that can deploy without warning.
The steering rack concern affects rear-wheel drive models and can result in a loss of steering control, raising the risk of a crash. The airbag issue involves the driver-side frontal airbag deploying on its own without a collision, which can startle the driver and cause injury or a crash. There is also a software fault in the emergency call system where an incorrect date and time can cause the system to relay a wrong vehicle location to emergency responders, potentially delaying help from reaching the correct site after a crash.
