I hope the issues I have with my 2021 Grand Cherokee have been eliminated.
Because the GC with electronic power steering is prone to severe shimmy under certain circumstances I opted to have the kit specific to the 2021 GC and Durango installed. Untold, until you get the operating manual ( a single page ) is when operating the kit will drain the GC battery in 3 hours, So I installed the kit, but there is no way to do a pre-trip inspection to verify the kit is operating.
The second larger problem is when the GC is taken from towing mode and back to driving mode, with or without the towing kit operating, you have no power steering for about 45 minutes. Evidently on GCs with the transfer case in neutral for towing the system disables the power steering, and when returning the transfer case to driving it takes 45 minutes to have the GC system restore use of power steering.
I am working my way up the food chain at Jeep to get a resolution on these issues that have been known for several years. If you need more info go to IRV2 web site and search for “death wobble” and GC power steering issues.
