Such a scenario leads to the engine turning off, which isn't a nice situation to find yourself in especially while the vehicle is being driven on a crowded highway. In addition to the previously detailed, Chrysler notes a further consequence of the condition. If the ignition sticks between "start" and "on", that may cause the loss of certain electrical functions, as in airbags, the power steering, power braking, the lot.
But here comes the most ROFL part of this particular recall campaign - the remedy for this fault is currently under development, so all of those 2008 model year Jeep Commander, Jeep Grand Cherokee, Dodge Charger, Dodge Magnum and Chrysler 300 vehicles are being recalled, but the fix isn't ready yet. As if that wasn't enough of a screw up, the American carmaker hasn't provided a notification schedule.
Nevertheless, affected owners are recommended to contact Chrysler at 1-800-853-1403 or the National Highway Traffic Safety Administration at 1-888-327-4236 for further info on this peculiar issue.
