On: city street, in stop and go traffic. Upon pulling off from a dead stop, the vehicle began jerking, then accelerating uncontrollably. I could not slow the vehicle with the brakes. If I had not moved the gear selector to neutral, I would have hit the car in front of me. Abs, anti-skid, and traction warning lights came on, and I barely had enough power to pull off to a safe place. After sitting a few minutes, I was able to drive the vehicle safely to the dealer. Dealer replaced right rear wheel speed sensor under warranty with what they called an "improved part", but there are three more speed sensors. *dt

Abs brake safety issue with 2014 mercedes sprinter 3500. Just completed 5,000 mile trip where the ABS warning light came on less than 200 miles after starting the trip. The ABS warning came on every day of driving after 5 to 100 miles and would reset after short stops with engine turned off for 30 minutes or less and the ABS light would go off but came back on after short distance. If the vehicle sat over night the ABS light would stay off from 5 to 100 miles the next day before coming back on. Several times when the ABS was about to fail the vehicle would begin to buck and the engine RPM would rapidly increase causing the vehicle to surge forward if going slower than 20 miles per hour. While the above is happening there is a grinding sort of noise coming from the engine compartment on the left side behind the firewall and if you are breaking at the same time it feels like the brakes lose pressure and the pedal goes to the floor.. Two times this almost caused an accident. The first was at a gas station where I just filled the tank and was pulling out of the station and the ABS problem occurred almost pushing me into the truck leaving the gas station ahead of me. The second time was in taos nm. I was at a red light downtown and when it turned green I turned left for a short way that LED to a stop sign and while stopping the vehicle it started bucking and then the RPM increased pushing me through the stop sign until I was able to hold it back pushing and pumping on the break as hard as I could. If the ABS fails when traveling above 20 miles per hour it sometimes bucks and then increases the RPM that can be controlled by breaking. One time I just let it go to see what it would do and it increased the RPM to 3800 before I used the break to keep it from red lining the engine.

Breaks are soft and spongy and the pedal goes within 1-inch from the floor. This is very nerve racking and unsafe. I have to start applying the breaks far ahead from where is normal and hope I stop in time. This rig is heavy and the breaks should work just the opposite to give more time to stop. Had breaks checked at dealer and they said they can't find anything wrong but wanted to charge me to flush breaks. Went to manager and they paid the cost to flush but the problem is still the same. This condition happens every time you use the breaks regardless of speed.

Brakes feel ineffective and soft on first application of pedal. Require 2nd application of brake pedal to feel confident braking action. Many other owners of this 2014 chassis sprinter 3500 report same issue. Dealers unable to diagnose or remedy the problem. Indicates a design / engineering flaw, rather than, a mechanical failure. This braking issue was consistent since we purchased the vehicle. Http://www.forestriverforums.com/forums/f191/who-else-has-soft-spongy-brakes-on-their-mb-93102.html

I have been experiencing the brakes felt very soft and made long braking distance. When I towed the small SUV, I thought it was normal because I was driving with over its gvwr. But all the time I have to step more time(like pumping) to stop even on driving under 40mph. It never allow me to step one time.
