Cruise Control problems of the 2020 Toyota RAV4

Tried to set radar controlled cruise control for the first time on a work trip to michigan at 70 mph. The steering wheel immediately turned to the left and took considerable pressure to keep vehicle straight. Took SUV in to shop and they said the radar controlled adaptive cruise control was working fine and they could not duplicate problem. This week took another work trip to michigan and the same problem happened about 20 times while trying to set cruise control at 70 mph. When I disabled the radar cruise control the problem vanished but the SUV would not detect traffic in front of it and of course would not slow down. Will try to video this problem and take SUV back to shop for a fix.
