2018 BMW X1 Engine

Car began to make a loud humming noise from the engine compartment and the car went stiff. The check engine light came on and when taken to have the light looked at, it showed a faulty thermostat.

Car does not idle when first starts. Shifting into reverse causes car to nearly stall. To avoid this, I have to touch the accelerator with extra pressure which causes the car to jerk uncontrollably backwards. This is a known fault on X1 BMW’s. BMW requires $300-500 to complete a software update with no guarantee this will correct the problem. The software update was completed once before in 2019 and the problem persists. They are asking for another payment for another update with no guarantee.
