I just realized that a number of us are giving FCA a way out of making repairs to our trucks.
I disconnected my grid heater relay from the battery about a week ago, but I'm still driving the truck and the hour meter is still running. The very first "test" the dealer is to perform is reading the runtime hours. If runtime is greater than 600 hours, the recall can be marked as completed, with no further action, no matter what relay is installed. I assume that they feel if the relay makes it through 600 hours of on and off cycling without failing, all is good. By disconnecting the relay, and driving until next February, runtime increases, but not service time on the relay. I disconnected mine at around 256 hours. By next February, I will probably still be slightly below 600 hours runtime. I bet some of you on this forum, and others out on the road every day, will go way over that 600 hour mark.
The relay will "test" as passed, and not be replaced, even though it's actual time in service was no where near the 600 hours.
I'm using February because that is the time frame I see most often for parts availability. Who knows when parts will actually arrive.
This scenario applies to the 2022 models specifically, although the runtime test is done on all model years.
You all get where I'm going with this. I imagine that I will leave my relay disconnected until the latest relays are available for sale to the general public, and replace it myself, on my dime.
