NHTSA Complaint #11531024 — 2021 BMW X5

While driving on highway/turnpike with cruise control on at 70 mph, drivetrain malfunction warning appeared and lost power. After turning off cruise control and playing around with buttons, could only get car to go about 35-40 mph, top speed with peddle to the floor. Very scary situation in traffic on busy highway. This happened twice about a month apart. First time, had to drive about 10+ miles in right lane with blinkers on to get to an exit. It was late at night and I didn't want to stop on my own. Once turned the car off and on a couple of time seemed to clear the error and I was able to drive city roads at minimal speed limit. Next day car was back to normal. Second time, drove about 2 miles to the exit with the blinkers on. This time when I restarted the car there was still not a lot of power. Drove for a bit but wasn't able to make it to speed limit of 45 mph. Made it home and turned car off again, next day it was okay. After restarting car a couple of times problem seems to go away. Took it to the dealer and all they did was "reset the system" which does not seem like anything is fixed. Will wait and see.
