BMW of the Woodlands

I recently purchased a used 2018 BMW X1 with 66,809 miles from BMW of the Woodlands. The CARFAX vehicle history report showed it was well maintained and while the AutoNation 125-Point inspection certificate noted a few items that needed to be repaired I was assured they had all been addressed. Two and a half months and 2,874 miles later while driving the car the transmission stopped working and I had to get the car towed back to BMW of the Woodlands. I was told that the driver front axle came apart and part of the pieces damaged the internals of the transmission, repairing the car (with a used transmission) would cost $21,159.44. Thankfully the car was still within AutoNation’s 90 day limited warranty and the transmission was listed as being covered. I was frustrated but I understand these things happen, I assumed I would get a loaner and I could just wait for the car to get fixed. Well it has been 2.5 weeks and BMW of the Woodlands still does not have any loaners available so I’ve had to make due without a vehicle. The only update I’ve been able to get is that the car is being serviced and they don’t know when it will be done. At this point I’m just contemplating buying another car and selling this one if I ever get it back. This is the worst car buying experience I’ve ever had and is not the type of quality or service I was expecting from BMW.
