Complaint Review: Gwinnett Chrysler Dodge Jeep

We bought a 2016 Big Horn truck from Gwinnett Chrysler Dodge on April 11, 2016.  We drove the truck and pulled our boat to the keys on vacation on May 6, 2016.  On May 12, 2016, the check engine light came on.  We had the truck towed to the Dodge dealer in Key West, FL.  The truck would not shift out of first gear.  It was repaired three different times in Key West.  The truck was transported to our home in Loganville, GA on June 6, 2016.  My husband got in the truck and it would not shift out of first gear, again.  It was immediately towed to Gwinnett Chrysler Dodge.  Eight days after the truck was towed to the dealership, they called to tell us the truck was repaired.  Because it had been over 30 days, we wanted to exercise our right to declare the lemon law on this truck.  We have left several messages with the dealership's general manager and he will not return our call and all the other managers are "out of the office."  We were instructed to call Chrysler on May 13th and you always get a voicemail, when they return your call two days later, they tell you they can't get through to the dealership and will call later in the week.  They will not give a last name, nor a location that Chrysler Corporate is located.
