NHTSA Complaint #11479846 — 2022 TESLA MODEL S

Tesla provides a back-up input form to its touch screen -- namely voice commands. Voice commands operate, among other things, map positioning, HVAC, lighting. Unfortunately, as quiet as the car is, the voice commands are a roulette wheel of results. 80% accuracy in detecting the specific command is the best Tesla manages. This would be a problem, by itself. However, even when the voice commands are accurately 'read back', and even when the voice command is one that Tesla explicitly has among the commands that Tesla reports (in its manual, etc.) to be an active function that produces an active result to the car's operation -- even then -- the commands/car still are unable to perform the documented function. 1) I commanded the car to 'turn on dome light'; 2) the car recognized 'turn on dome light'; 3) the car acknowledged 'dome lights on'; 4) but the car did not turn on the dome lights. The entire user interface operates in a random way at random times in random traffic. This is a recipe for distraction. Tesla needs to encourage eyes-up, on the road. Instead the multiple stages of failure, result in many unnecessary risks. The car was/is made available to Tesla's service center, and they are aware of the contents of this report. I expect zero result from their 'diagnosis'. SW release is 2022.20.8.
