Koons Tysons Chrysler Dodge Jeep Ram

TL;DR: Car wasn't fixed. Don't bother with the service form on the website. The only method of communication is through phone. Context: The electronic trottle control light on the dashboard of my mother's Chrysler Pacifica came on so I went to Koons to get this resolved. The car is important as it is my mother's only means of commuting to work. I was taking my own time off work to take the car for service during the weekday. History: We had this exact same problem occur about a year or so ago. It was "fixed" here so I brought it back. 6/23, (trip #1) Arrived with car after making an appointment. Since the ETC light comes on intermittently and it came on while I drove up to service counter, I was told to leave the car running. Car was examined and found to have a faulty computer. Another appointment was made to install the part when it came in. They used up half a tank of gas during this examination with no notice or compensation. 7/6, (trip #2) Arrived on the date the appointment was made. Waited about an hour before the service advisor told me that the computer had not come in yet. Asked them to call me when they got the part to set up another appointment. 7/9, I get an automated email saying the part had arrived. After a couple days, I call to set up an appointment. (trip #3) The computer was replaced but I was told another part of the pedal became bad. 7/24, I got another autmoated email saying the part had arrived. Used the website form for service to set up an appointment. After a few days with no confirmation, I called to confirm - only to find out the appointment was never made. Managed to make an appointment anyway. 7/29, (trip #4) The pedal part was replaced. 20 minutes after taking the car out of the lot, the ETC light came on. Frustrated, I left a voicemail on the most recent service advisor, asking him to call me back the same day. 8/11, I have not heard from anyone as of this day. While the service advisors were pleasant in personality for the most part, NOTHING WAS FIXED. This is VERY disappointing. ...and since it's a rate-able: Shuttle service was available but a loaner was not offered.
