Just got back from OBX and took the Jeep out on the beach. I drove about 6 miles up the beach north toward VA and everything went smooth, then turned around and on the way back the sand was looser in the area where the southbound traffic was driving. No worries as I had already done this a few times in my 2008 JKU with no problems in previous years. This year, I was in my 2019 JLU and the TCS light came on multiple times and I felt as if I was loosing power, so I turned it off below the radio. I still felt as if I was loosing power at times in the softest part of the sand. I was in 4HI the whole time. So this is my question...I never had this issue on my 2008. It does have the TCS, but I only get the dash light if I fishtail maybe on a wet road in 2HI. I never get it in 4HI. Is the system a little different on the 2019 models? Any help with this would be appreciated. I am going to Florida in a few weeks and will take it on the beach again, but want to get a better understanding of how the 4WD drive system is operating. I was never in danger of being stuck, but the loss of power I felt makes me want to understand what is going on a little better as the "feel" of the drive was quite different then my 2008 in the same conditions.
