Suspension & Steering
If all four wheel sensors in the subject vehicles are simultaneously malfunctioning or missing, the TPMS will provide an initial warning, but this warning will not automatically repeat on subsequent ignition cycles, failing to remind the driver that the system is offline. Driving unknowingly with incorrectly inflated tires may result in sudden tire failure, increasing the risk of a crash.
The system that monitors tire air pressure may malfunction and not illuminate a warning light all times low pressure is noticed. This can result in unintended low air pressure or imminent tire failure that goes unnoticed, increasing the risk of an accident.
Mercedes Benz notified owners of affected vehicles starting in September 2014. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them.
