What about gear shift recall?
The faulty gear shift design in jeeps has caused multiple crashes, injuries and at least one death. RIP Anton. Unclear if they have even notified owners or if they have a fix yet. Meanwhile, try to avoid getting killed by triple checking that the vehicle is in park, and firmly setting the parking brake before exiting vehicle.
'Hackers' are hardly at the top of the list of things to worry about when the vehicle has fundamental design defects. And I agree that the payout for reporting vulnerabilities is so low few if any (white hat) researchers will bother.
