It is typical for me as the climate gets warm. I believe it is the battery conditioning. I have had mine for nearly a year and it gets real loud when Temps hit 100. I have been on Level One charge all this time in the car port. No issues.
I bought the Rubi 4xe with the steel bumpers. Installed the Mopar bar and Warn winch. I would say my electric range sits at 21 with an overall range of 295ish. Warm climate driving.
Finally got word of in transit. Ordered mopar optioned hella yellow rubicon on 02/08. It has been sitting done for over a month. Expected 05/07-05/21 in AZ.
