Car will drive on interstate then will be unable to accelerate on interstate warning, -??Propulsion power reduced-?? light turns on and vehicle speed decreases and car does not accelerates and loses speed. I had to stop vehicle multiple times to reset the car per advice on the internet but car continues with drastic decrease in speed on the interstate and message -??Propulsion Power Reduced.-?? Car is serviced as per car dealership recommendations but now car is not safe to drive on the interstate.
