    On the way down to OBX last week, I got a parking light out warning on my 2015 trailhawk. At the next stop, I checked all the parking lights without turning it off and it was fine. After turning it off and back on, the warning was gone. Then it started raining pretty hard and I got a traction control disabled alert which also went away after the next stop/start.

    Heading up the beach, I hit a little salt water (i.e a splash that sprayed the side and underside of the jeep with some splashing the base of the driver side window) so first thing in the morning, I took it through about 10-12" of fresh water to help wash it off. I then headed out to the beach where I got a dynamic torque steering error and 4wd turned off. It stayed in auto and I'm pretty sure 4wd was still working when needed as I could feel it kicking in a bit when the front tires started to spin going through the soft sand on the way up the dunes off the beach. When I got it back to the house, I gave it a good wash down underneath and it was fine all week at the beach with no errors.

    Coming home, it was ~95 degrees out and quite hot. The AC wasn't working very well. After stopping for gas and then starting it back up, it blew ice chunks out of the vents. AC started working a little better but not great. Now the AC isn't working too well and I'm hearing a hissing sound like a nitrogen bottle filling coming from under the dash.

    Any thoughts on the AC issue? Sounds like it is low on freon but if there is a leak I'd like to Id that first as it just timed out on warranty (of course). Is it worth taking a look at the cabin air filter? Would driving on the beach/in the sand for a week require a change/cleaning? Where is the intake?


    Any thoughts on the seemingly random"can bus" issues?

    I have gotten those random errors on my 2016 Trailhawk to, and they stopped after a little while. The 4WD is concerning, but the A/C blowing ice is VERY concerning. That could be a system failure, and I would get that checked out right away, before it gets worse...

    Took it into my local AC shop. The liquid line (the black plastic one) is leaking at the T. Seems like a really bad design. In all it's going to cost a grand to get it fixed. (30 days out of warranty) Jeep came up with a similar number. Seems like a perfect part for someone to make an aftermarket replacement for. The part is ~ $300, 1234 ~300 3hr to replace it and another hour to service it. Jeep only wanted 1.5 hours to replace it but wanted ~$600 to service it so the price estimates were about the same and the local guy is a few blocks from my house while all the dealers are on the outskirts of the city.
