Vehicle Shudder problems of the 2013 BMW X3

My 2013 X3 just dead on me in middle of highway, on my way to work, without and ahead notice, it was just not even 30 seconds sign of "oil pressure low" then check engine light on, car was shaking, it totally lost the power, I called road service to tow it to dealership. When I called the BMW service center, the girl just told me to clam down, doesn't need be upset. I was super upset, never expect to drive a car suddenly dead in middle of highway, it could easily get me killed, or cause seriously car accident. It was happened last may (2019), at mileage 88k, two options: trade it in for $2k or fix it $11,500 with replace new engine. I end paid it all from my own pocket. It is just one year later, the warning sign on for " drivetrain malfunction, drive moderately, maximum drivetrain output not available" sent it to dealership, I was told the turbo need replace, quote for $5500. . . How could BMW sold those poor designed crap to their customer, the issues just one after another, very disappointed, such shame on BMW, I would not buy any BMW anymore.
