Tone wheel failed at 68,300 miles, my vehicle shut off mid driving at 50mph and lost all power to accelerate and power steering and lastly ability to start. Luckily it was later in the day and traffic was light and I was able to coast onto a shoulder. safety recall 66a was only a flash fix which was all that was available on my truck while the known issue of 73a on my truck engine (tone wheel) is what failed and put mine and my sons lives at risk unnecessarily. FCA should be responsible to fix this known issue at their cost as it is an extremely dangerous situation that occurred. I am currently fighting with dealer and FCA to cover this so I only have the scan code and dealer fix for documentation at this point.
