I recently bought a 2022 Prius XLE. It's a wonderful car except for what I believe is one fatal flaw. I shared this with my local dealer, who shared my concern. Apparently, this is a 'new feature'. When one sets the dynamic radar cruise control, the vehicle 'generally’ corrects the car speed with a car/truck in front that is moving slow, i.e., by slowing down. If one decides to pass on the left and activates the left turn signal the Prius automatically begins to accelerate EVEN IF I DON'T SWITCH LANES. It eventually corrects itself, but only after several seconds. Coupling this acceleration with the car/truck ahead possibly slowing down, can lead to a fatal accident. According to the dealer tech, this turn signal override can not be turned off. This situation does not occur when moving to the right lane. That is, activating the right turn signal does not automatically make the car accelerate until the car has cleared into the right lane. To add to this complication, let's say you wish to pass on left and there is a car in the left lane, the turn signal override still activates and you accelerate. Now you are boxed in and MUST deactivate the cruise control. I know of no other car that has this 'feature'. That is, cars do not accelerate until they have cleared into the new lane of traffic. This should be corrected by Toyota or at least create an option enabling the driver to turn off this feature. When one passes on the left the typical procedure is to turn on the signal, look to make sure the lane is available, and then proceed to pass. Toyota's new 'feature' makes this dangerous. Thoughts? If others have experienced this issue-please formally notify Toyota. If there are enough complaints, and hopefully no accidents, maybe Toyota will modify its software.
