2017 Toyota Avalon Engine problems

Leaving a parking lot, the car jumped out of gear. Thought maybe I had bumped the gear selector but attempts at putting the car in gear resulted in grinding noises and the only option was to put it in PARK. Check engine light came on. Mechanic diagnosed a speed sensor. Had this happened on the freeway or while trying to pass another car on a two lane and a speed sensor disable the entire car to me is dangerous and should be addressed. Had the check engine light come on, I would have had the sensor replaced right away. I now feel this is an unsafe situation that could arise in other 2017 Toyota cars

Toyota's failure to install an auto-stop caused the carbon-monoxide poisoning of two (more) people, many dozens of such deaths reported. (Detail: they had likely stopped the engine, but the wireless fob can re-start; and this model has an auto stop/start function that can also lead to death.] Note: not my car, my parents.

Toyota's failure to install an engine auto stop caused the carbon monoxide death of two people. Car was stationary. Failure to have proper outside warnings like a honk to warn the operator not to remove the key from the car led to this death.

Toyota avalon fails to have an ignition auto shut off which led to death of two individuals. This design flaw did not prevent the car from idling indefinitely and filling the house with carbon monoxide' a toxic fatal gas. The car does not have proper external warnings like a honk to advise a driver they may have removed the key from the car.
