AutoNation Toyota Arapahoe

Made an appointment to get my speedometer changed out. I had to leave my 4Runner for odometer purposes. I also asked to have the rear door fixed because it would not open. I left the car at the dealership on September 13. Got a call on sept 19..... I was told the car should be ready by the end of the day.....Got a text on Sept 22 my car was done. I informed them I would be out of town and back on Tuesday the 26 to pick it up...Picked up the car on the 26th....drove the car to the store and opened the rear door to put in groceries...when I tried to close it it does not lock. Took it back to dealership. They looked at it , and tell me it will need another part. I was told the service person would have to talk with the manager to see if they could give me part at cost and no labor charge and he would let me know. Never received a call back concerning this issue plus I do not trust driving the vehicle because the rear door might malfunction and I them will not be able to lock the car because th rear door does not latch properly....I called the dealership on Oct 3 to see about the fix and the added cost part at cost and the no labor charge. Talk with the service manager, he says I will get part at cost and no labor but he has to order part and will let me know when it has arrived. My thoughts are, you have a vehicle for 13 days and you could not fix the rear door issue within that time line and now I have to wait until the part gets in and drop my vehicle off again and wait another few days to get it repaired. the original cost to fix the $770.33 but now I have to pay more because of a extra part? No happy with the outcome
