The 1993-1998 ZJs are going to be a recall, so will the 2002-2007 Libertys. The 1999-2004 WJs will be an inspection only, no hitches installed.
Overall the whole thing is straight BS and fear mongering, 1 death for roughly every 5 million years the vehicles have been on the road. I really hope that Chrysler only pays for the ones that are newer than 10 years and makes the customer pay for the others, might help dampen the "give me free crap" attitude.
