I purchased a Mustang Mach-E from **** in February 2023, I've continue to had problems with the screen not properly working. I took it in to the dealership a couple of times, they had my car for days up to a week and half saying they are able to see through the car data that there was in fact a problem but could not help me since the problem is not occurring while the vehicle is at the dealership. I showed them all of the videos that I have of the screen lagging, freezing, not connecting. I sometimes have a hard time opening the doors as well. I tried to go through the buy back and they denied my request due to there not being any problem with the car, although I offered to present the videos I have saved. They said that I would need to contact the BBB in order to resolve this. I did not want to go through the BBB and wanted my car fixed. I took it to the **** dealership again because it was lagging way too much. They were able to see that it was not Properly working as ****, the store manager drove my car and was able to witness the screen lagging. He then took me to services and spoke with them telling them he witnessed it not working properly. I took my car in the next day. I told **** in services I just wanted my car to work properly. They gave it back to me almost a week later due to the holidays, no big deal. However, the car screen is still lagging. I have recorded additional videos since then. I no longer want this car at it is always lagging and are making it impossible for me to get rid of it. They said I could trade it in but would have to give another $5,000 as a down payment for another car. I do not want to give another down payment. I would like to get rid of this car as it does not properly work. Thank you for your time.
