How can I report to Mercedes Benz an unsafe situation with one of their cars that could affect other cars of the same type?

Asked by GuruTPQTD Jul 13, 2018 at 12:13 PM about the 2011 Mercedes-Benz B-Class B 200

Question type: Maintenance & Repair

My wife s  Mercedes Benz B200 which we bought new in 2012 ,with only
about 50,000 kms in total ,had a stange incident . The car was operating at
about 30 kms per hour and suddenly , with the engine still running , the
wheel became very hard to steer and the car slowed down to a minimum
speed to about 5 kms per hour . She managed to park the car which was
later towed to a Mercedes Benz Rep garage (La Merced Pilar Argentina)
where they have diagnosed the source of the problem as wastage of a
sensor in the braking system of the car.
If this sudden complete loss of power and steerage in the car had ocurred a
few minutes later in the middle lane of a 6 lane highway and the car
operating at 100 kms per hour she could have had a serious accident .
The explanation I am being given does not sound satisfactory and in fact if
indeed wastage in a sensor can produce this effect of blocking the car
completely it should be reported to the manufacturer who should correct it in
all similar cars as it can result in life threatening accidents .

Many thanks Tom . You may find it incredible but they do not have an e mail address where I can send my question and the telephone number I can reach in Germany tells me they are closed . Terrible service!

Double check your cars manual, the information should be towards the back.

I just the case with Mercedes Bez repair people locally. I want to share with you their comments : The car is designed so that the four RPM electronicsensors in the wheels provide information to the cars computer . A failure by one of these sensors in this case caused the car to auto block itself leaving it suddenly with minimum engine power and making the steering hard to move . They have never had the case of a car having this problem at high speeds and therefore they have not registered a serious accident as a consequence of this failure . When they detect a failure in one of these sensors they generally change the two parallel ones (ie front or back). as these sensors are electronic components there is no way to anticipate a possible failure and there is no planned rechange of the sensors over time . The only solution offered is to change the two sensors at considerable cost to the customer but with no guarantee that the same thing could happen to the other two or to the two new units that they are installing for that matter . I find this explanation rather extraordinary as it offers no solution to what could potentially be a fatal accident if this happens in highways at high speed. Obviously Mercedes Benz does not take the safety of its cars very seriously.

So a bad wheel speed sensor renders the car inoperable? Got to love German engineering!
