Intermittently over a few week period, when the brake pedal was pressed at a traffic light, the pedal would go soft and the car would start to move forward. I would press the pedal harder and it (sometimes) pushed back against my foot. On two other occasion when trying to stop when coming to a traffic signal the brakes were slow to respond, as if they were not power brakes, and I had to really lean on the pedal to stop the car. This must be a frequently recurring problem given the fact that several other owners have posted the same/similar problem with their car AND, when the mechanic who fixed the problem could not get a replacement brake booster for more than three weeks because there was a 3 to 6 week NATIONAL back-order for the part, according to the Chrysler dealer in our area.

While taking my wife to the local ER during a steady rain, we stopped at stop sign controlling traffic in (4) directions. While braking to allow pedestrians to pass the brakes begin making a hissing noise, the brake pedal began pulsating then the brakes released. My first thought was to begin stepping on brakes as there was a nurse going to parking lot directly in front of my vehicle. The car stopped and I immediately pulled over into a parking space and visually inspected the brake pads (which were ok pads were of sufficient width far from sensors) I also checked brake fluid which was at the max fill line. This was the scariest issue I have ever experienced in my 30 years of driving. I have driven commercial vehicles since age 21 have never been involved in a collision of any kind. I have re-certified in defensive driver courses over the last 30 years. This incident truly scared me a defenseless health care professional/pedestrian could have been harmed.
