The 2018 Mercedes-Benz AMG S63 has 6 recalls, the most serious being an oil feed line to the turbocharger that can leak onto hot engine or exhaust components and start a fire. A separate structural recall covers the roof's front panel, which can lose its adhesive bond, detach from the vehicle, and become a hazard for other drivers on the road.
Three recalls involve the lane-keeping and steering assist systems. The hands-off detection system can malfunction and leave Active Steering Assist engaged even when the driver's hands are not on the wheel, which can allow inattention to build unnoticed. Separately, the Active Lane Keeping Assist has a software calibration issue that causes it to fail to intervene during an unintended lane departure at speeds above 65 mph. There is also a recall covering the automatic crash notification system, where a malfunctioning eCall unit can send emergency responders to the wrong location after a collision.
