I bought my van Chrysler pacifica back on July 30 2018 after couple months after I stater noticing sliding door driver side when trying to close it either by key fob inside button nor door was not closing any once need it to try 3 or 4 times to close all the way then radio turning off I called a web called pacifica cares then I was reach by them I was told to provide a email phone number time and date of appointment name and address of the dealership then y was reach by one case manager I share with her the issues we agreed on the appointment at the date and time which was yesterday 2/26/2020 8 am she said she called them explained to them what was going to happen at the date and time so I got to the dealership and none had a clue about my reason so I explained to service person he said you can't generalized and said the isn't no issues whatsoever which pacificas I called case manager but she wasn't reachable because she's in other state so I was told by advisor at the service that she never talk to him after two hrs I was reach by my case manager and then explained to me that I need it to pay the diagnostic to be able to move forward in the case which it cost 140$ I told her that I was never told that I need it to cover that out of my packet before they can make any decision at this point I'm very disappointed and upset because I was never told that I need it to pay for this diagnosis if I can get any help will appreciate.

Radio malfunction causing no audible noise for turn signals, seat belt indicator or key left in ignition indicator.

The car hesatates, the radio some times does't come on, the seat belts do not tien up when you buckle up, and the seats are very low to the ground for a handicap person.
