"The electronic gear selector in vehicles like Yelchin's return to the upright position after a driver selects Drive or Park. In other words, it doesn't remain in the position the driver moves it to for parking. At a glance, that could make it difficult to be sure the vehicle was actually in Park."
"Weeks before Yelchin was killed Sunday, Fiat Chrysler had sent a written recall notice to owners warning them to make especially sure their cars are in Park before getting out of the vehicles. The notice also said they would get another letter later indicating when they could get their cars fixed."
