Brake Master Cylinder Problems of Chrysler Pacifica

Purchased 2019 Chrysler Pacifica limited in July 2020 with just over 30,000 miles on it. Last week the master cylinder for the braking system started to act up. When sitting at a stop light/sign the brakes start to make a loud hissing sound and push back against my foot forcing me to push the peddle all the way to the floor with more force then should be needed. This causes the breaks to disengage and the van rolls. I am forced to put the van in park at stop lights so I will not roll into traffic or vehicles in front of me when I am supposed to be stopped. Sometimes I am on a decline or even just sitting on a straight away waiting at a stoplight/sign. This is a major safety issue as I have my kids in the vehicle 90% of the time. I am not the only person with this same issue that I have seen on the forums and NHTSA this needs to be addressed.

From the time the car was new when the abs or traction control was engaged the car made a clicking noise. As never having a car with this feature I thought was normal. In March of 2010 my brakes failed on my 07 Pacifica. Upon taking the car to the dealer I was informed that there was contaminated fluid in the brake system and the entire system had to be replaced. New calipers, abs module, lines, hoses master cylinder ect. The bill was $2500 which I had to pay because they are claiming contaminated fluid. I had been the only person to service the brakes on that car and did not add fluid when replacing the front pads. When the failure occurred the car would come to a stop and start rolling again. I avoided crashing by standing on the pedal as hard as I could. After replacing the entire brake system the clicking has stopped. I have driven Chrysler/ Dodge cars for 12 years. . . This one may be my last.
