I have a 2015 Jeep Cherokee Trailhawk that I once experienced the death wobble while it was being towed. I have since got the, so called, fix from Chrysler. They installed a wiring harness, switch in the console, and added some software in the Cherokee. So far I haven't had a problem. The dealer said that the wiring harness applies power to the electric power steering when the fuse is in and the switch turned on.
What makes me mad is that Jeep advertised that the Jeep could be flat towed and that there were no switches to change or fuses to pull. Now I need to install a fuse, operate the ugly switch in the console, and remove the fuse and turn off the switch every night when parked while towing. Also, Chrysler suggests a battery maintainer be added so the battery won't run down while towing. The dealer said that the electric power steering take quite a bit of power when activated via their fix. As far as I am concerned Chrysler did false advertising that the Cherokee was ready to tow. I think everyone who has a 20014/2016 Jeep Cherokee that they tow should get a Class Action suit against Chrysler to have the fix and a battery maintainer added at no cost to the owner and a monetary settlement for the inconvenience this causes the owners.
