Twenty years ago I was doing shifter mechanism recalls at the Chrysler/Jeep dealer because the Park detent wasn't as 'pronounced' as it should have been.
Then a solenoid-actuated cable was installed so that you had to have your foot on the brake before shifting into or out of Park. You could not remove your ignition key without the vehicle being in Park.
Some customers didn't like the new 'feel' of the shifter after performing these recalls. Making the shifter detents more positive also made the shifter movement stiffer.
Legally I couldn't un-do a recall once it was done.
One of the most unpleasant shifter recalls was E17 for diesel Rams. If you open the drivers door and aren't in Park, the horn will start honking and the headlamps will flash. Some drivers said that they needed to open the door to look while backing up, because the mirrors were insufficient or they had a wide trailer, etc. This was awful if they had to back up this way late at night in a residential neighborhood. I couldn't un-do this recall either, it was a software flash in the PCM. Once done, it is done.
Safety Recall E17
There have been dozens of these shifter recalls and there is nothing wrong mechanically with any of these vehicles.
I have to say that it is distracted or inept or inattentive drivers that cause the concerns. The range selector PRNDL indicator is in the line-of-sight, so the driver won't forget what gear they are in.
Some people may be unfamiliar with these new 'Euro-shifters'. Introducing new shifter styles may be a learning curve for some.
The 'gated' shifter where it drops into slots for various gear ranges has been around awhile now, while conventional American shifter levers always used to move in a straight line.
The Knob® is a novelty like the push-button automatics of old.
A shifter's operation needs to be intuitive and fail-safe for selecting Park. If I miss a Park shift, then it is a failing on my part. If injury or property damage occurs because of one's failing to ensure that a vehicle is placed in Park, then the lawyers get involved. The same for drivers who hit the gas instead of the brake. It is a litigious society that we live in today.
The automakers have to always err on the side of caution, even when there is absolutely no mechanical fault with the vehicle. They also have to cover 'operator error' for those drivers that make mistakes.
