One problem related to abs brake fail has been reported for the 2004 Mercedes Benz E500. The most recently reported issues are listed below.
While traveling along a 2 lane highway in a snow storm, the sbc pump failed and caused the abs to fail as well as the brakes to barely work. The subsequent skid forced a very close call with a fully laden logging truck, and could have easily been a fatal accident were it not for good luck. Under NHTSA recall 2004 050014, and recall campaign 2005070007 apr06 by mercedes, the sbc pump failure is a known safety issue. The local Mercedes Benz has offered to sell me a new one for $1700 as Mercedes Benz USA is not willing to replace this failed part under the recall as they only offer a 10 year window. Isn't a safety recall a recall? brakes are a vital aspect of safety. . .
