Brand New BMW always breaking down

I purchased a brand new 320i BMW from Auto Glen Motors (R589000). Firstly the salesman was not transparent when he sold me the vehicle. A repayment of R5k then went to R7500 (not going to go into that now) Anyway this vehicle has broken down over four times already, BMW SA and Auto Glen Motors cannot accept responsibilty for the defect of this vehicle. They cannot find the problem as to why the DRIVE TRAIN warning light comes on and shuts down the engine and they expect me to take back the vehicle everytime. I am waiting for the Motor Industry Ombudsman to open on the 15 Jan 2018 to see how this issue would be resolved. I have also liased with Merissa Chetty from BMW Customer Care to try and resolve my problem. MC said she needs to chat to the Dealer Principal @ Auto Glen Motors and get back to me. I honestly dont want this car back. This car spent more time at the dealerships than with me. I would any day buy a Toyota. BMW SA change your attitude. I am your customer and every customer counts in this day and age.
