Mercedes-Benz is recalling 6,200 S-Class sedans, coupes, and convertibles from the 2018 and 2019 model years because their automated steering functions, such as lane centering and lane keeping assist, may continue to work even when the driver’s hands are off the wheel for a prolonged period of time.
When it is working as intended, the system should sound a warning if it doesn’t detect the driver’s hands on the wheel. If the driver doesn’t respond to repeated warnings, the car will turn on its hazard lights and slowly come to a stop.
The system’s failure is a problem because a driver’s inattention may increase the risk of a crash, according to the National Highway Traffic Safety Administration. Additionally, the system may not trigger warnings that tell drivers to keep their hands on the wheel and won’t bring the vehicle to a complete stop automatically.
The recall follows a similar problem with the 2019 Lincoln Nautilus SUV. Approximately 2,700 of the SUVs were recalled in January because of a faulty hands-off detection system.
The Details
Vehicles Recalled
• 2018 to 2019 Mercedes-Benz S63 AMG, S450 4Matic, and S560 4Matic sedans
• 2018 Mercedes-Benz S560 coupes and Maybach S560 sedans
• 2018 Mercedes-Benz S63 AMG 4Matic coupes and convertibles
All affected vehicles were manufactured from Feb. 7, 2017, through Aug. 3, 2018, and equipped with Active Steering Assist.
The problem: On vehicles equipped with Active Steering Assist, partially automated steering functions may remain engaged without warning to the driver (as the system is supposed to do) when a driver’s hands are off the wheel for a prolonged period of time.
The fix: Dealerships will perform a software update to the Active Steering Assist system at no cost to owners.
How to contact the manufacturer: Mercedes-Benz began notifying owners of affected vehicles Feb. 15, 2019. Owners may contact Mercedes-Benz customer service at 800-367-6372.
NHTSA campaign number: NHTSA’s number for this recall is 18V910.
