NHTSA Complaint #11467436 — 2020 TOYOTA RAV4

I was driving on an Interstate highway with th speed control on in extremely light traffic and very heavy, slushy snow when the brakes were applied full and the instrument panel flashed red. There were (fortunately) no other vehicles in front or behind me. Since there was no reason for stopping, I stepped on the accelerator and the vehicle operated normally EXCEPT that I was no longer able to use the speed control. Calls to Toyota's 800 number were of no help, but a service advisor at Sunrise Toyota suggested cleaning slush off the Toyota logo on the grill. After cleaning the logo, the car operated normally. Toyota subsequently examined the car at the dealer and determined that it was operating as designed. I BELIEVE THAT THE VEHICLE'S SOFTWARE DESIGN IS DEFECTIVE AND MUST BE REDESIGNED.
