We have a 2011 Dodge Caravan. There is a strange brake failure problem that only occurs once every 1-2 month. When the problem occurs, there is no resistance when we push the brake (the feeling is like pushing the gas pedal) and the car does not decelerate at all. We have to push the brake multiple times and we could hear the sound like pumping air. After that, the brake works normally again for another 1-2 months. Both my wife and I have experienced this failure multiple times so we are sure this is not the driver’ fault.
We brought the car to Dodge dealer multiple times. The first and second time, they said that they could not find any problem. The third time, they replaced the master cylinder for brakes for about $900. One week later, the problem occurred again. This time, they said that the problem was hydraulic control unit and one door of the unit does not work properly. The repair cost will be another $700.
Do you think that this is really the root course of the problem? Is it worth to do another repair? Or we’d better just sell the car? Thanks,
