While accelerating from an on-ramp to a highway, an alert popped up: Drivetrain malfunction: Drive moderately..." the car lost power and I was nearly rear-ended and nearly caused a multiple car accident on the freeway. I was able to get the car to the side of the road during heavy traffic. I turned the car off, opened the hood and looked inside. Nothing seemed amiss. Restarted the car and the yellow alert was gone. Proceeded to get back on the highway and accelerated again and again the alert popped up and I lost power and again nearly caused an accident. This is a very dangerous malfunction that seems to be occurring with high frequency. Please look into this as government intervention may save lives.
