Mercedes-Benz recalled CL Class, CLS, E Class vehicles built between 1 January 2001 and 31 December 2005.

The recall notice describes the fix as: that are likely to be affected and mount an additional bracket to the electrical harness to prevent relative movement. You won't usually pay for it.1

What’s Wrong

In isolated cases it is possible for vibrations within the vehicle to in turn vibrate the wiring harness connected to the Sensotronic Brake Control unit. This causes the internal contacts within the unit to suffer abrasion and subsequent resistance increase. The resultant affect is that more effort will be required on the brake pedal to stop the vehicle.
