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.

Lane sense behaves erratically in certain circumstances; alerts loudly and request hands be placed on the steering wheel when they are already on the wheel and am traveling safely within a lane; no lane changes. Has alerted in driveway as well and alerted for service. Took to dealer and they could not replicated or determine problem. They provided informational flyer on lane sense but it does not match reported conditions/alerts I received on auto's console. Consistently fails and behaves erratically going northbound on golden gate bridge - in all lanes and on multiple occurrences. Occurs in various environmental conditions from fog, clear day, rain, etc. Occurs in motion and when car has been still/stopped (in driveway.) system alerts and then automatically deactivates itself. I don't know that manufacturer and dealers have full understanding of behavior; especially the detection of what the car believes are no hands on the steering wheel/feedback torque.

The steering wheel pulls to the right or to the left while driving at highway speeds. Happens randomly ' never know when it will turn in either direction. When driving at 60-65 and passing a slower vehicle, it often requires firmly guiding the car against resistance back to the lane. Requires driving while grasping the steering wheel firmly to prevent the vehicle from veering from its path. Will also occur at lower speeds but not as often. Also, when driving on an expressway the steering, sometimes but not every time, becomes unstable if a truck passes it. In those instances, it veers to either the right or the left. The concern is that it could veer directly into the passing vehicle if the driver is less than alert and not firmly grasping the steering wheel. During a lifetime of driving, I have never before experienced a vehicle that felt as dangerous as this one. I took it to the dealer who proclaimed it in perfect running order. I filed a complaint with the Chrysler (case number 58533009) and was advised to take it back to the dealer and try to convince them to take it on a test drive. However, the dealer said they test drove it, which is doubtful since the mileage number did not change while it was in their hands. The dealer highlighted a comment on a report titled 08-electrical/be-electronic control modules/module, electric power steering (epsm)/description and operation that reads: Variable servo steering: When the speed of the vehicle is increased, the module reduces the amount of assistance to the column. Possibly Chrysler, in that statement is revealing that the steering mechanism is unsafe at highway speeds.
