9 Service Brakes problem of the 2006 Mercedes Benz CLS500

Failure Date: 08/21/2017

I was entering onto a highway (100). At the point of the highway I was entering(from cty rd 81) it opens the highway to a 3rd lane on the right side of the highway. At the same place it opens the highway up, there is an immediate exit(42nd Ave). As I am accelerating to highway speeds, just prior to the new lane availability that drivers must enter to get off on 42nd, my car starts chiming and there's a red warning on my dash that states "stop, reduced braking power. Depress brake fully. " or something quite similar. There is no shoulder, I'm going like 10 mph, terrified. People are honking and trying to get over to get off on 42nd Ave in a lane where I'm going 10 mph and they were at a speed of approx 60 mph(posted hwy speed). As I limp my car past this exit to a shoulder I then attempt to brake and have no braking power. I eventually rolled to a stop. Turned my vehicle off to determine my next move. I turned the vehicle back on to see what exactly the warning light said- there was nothing there. Tested my brakes a little on the shoulder and they were fine. I was able to drive the rest of the way to my destinations without any problems. This has since occurred a couple more times. Through a trip to the mechanic and thorough research it is determined the problem lies in my sensotronic brake pump. This is a pump that mercedes warrantied for 10 years due to this issue. This will occur to all other drivers of this vehicle that haven't had this part replaced. I never knew of the safety issue with the braking system until this problem occurred. I would have replaced it years ago (under warranty at the time of replacement). My children's lives, my life, and the lives of all the drivers on the highway that morning were placed at severe risk. This should have been recalled and still should for all of the other unsuspecting drivers- for their safety and others on the road.

12 Service Brakes problem of the 2006 Mercedes Benz CLS500

Failure Date: 02/01/2016

This vehicle is equipped with sensotronic brake control that has a service threshold. When this threshold is reached the brake system defaults to non power assisted hydraulic mode to the front wheels only. This occurs without any prior warning and results in increased stopping distance. I have sent a copy of the mercedes service bulletin s142. 46-p-0012a which addresses this issue. Mercedes stopped installing this system in 2006. At the very least, mercedes should issue a mandatory recall to interrogate these vehicles with star das to determine how close to the service threshold the sbc unit is and replace them at the dealer's expense. The warranty has been extended to 10 years, unlimited mileage, so mb knows of the defect. Unfortunately, many vehicles are outside this 10-year window, yet the problem should be fixed. This is a major safety issue that needs to be addressed.

15 Service Brakes problem of the 2009 Mercedes Benz CLS500

Failure Date: 07/17/2013

I received a warning on my dashboard that my rear tail light blinker was not functioning correctly. The passenger side blinker was not functioning correctly. Upon testing the hazard lights the blinker was correcting and after restarting the car the light functioned correctly. 2 weeks later I received the same error again, turning off and on the car did not correct the issue. Upon opening the trunk and inspecting the light I noticed the top brown wire that was attached to the tail light harness was blackened and burned as if the wire was overheating and effecting or burning the harness. The tail light still intermittently works on and off however the blackened wires are a concern to me that it could become a fire hazard.

17 Service Brakes problem of the 2006 Mercedes Benz CLS500

Failure Date: 02/09/2010

Brakes on 2006 mbz cls 500. Replaced twice with brand new brakes from mbz dealer, drove less than 3000 miles, brakes squeak like a train three weeks after each installation. Dealer wants to wash their hands by saying its normal. How can brand new brakes squeak twice after new replacement and very few miles of driving? they really need a check up and recall. Its ridiculous for new brakes to squeak that loud, you can hear me from another corner.
