Mercedes-Benz S 560 Recall 18V908: Steering Assist May Stay On With Hands Off the Wheel

NHTSA campaign 18V908, reported December 19, 2018, 5,754 vehicles potentially affected.

What this recall means for you

Some 2018 Mercedes-Benz S-Class vehicles may have an incorrectly installed steering boot. Because of this, the Active Steering Assist system may stay engaged even when the driver's hands have been off the steering wheel for a prolonged period.

If the system remains active while the driver is not holding the wheel, the driver may become inattentive, which increases the risk of a crash. Owners should be especially careful to keep their hands on the wheel and pay attention to the road while the system is in use.

Mercedes-Benz will repair the problem free of charge. Dealers will inspect the vehicle and correct the steering boot installation as needed. Owners can contact Mercedes-Benz customer service at 1-800-367-6372, referencing recall number 2019040025. You can also check your VIN for open recalls on NHTSA's website.
