Yes, the thermostat/housing was replaced today. Drives fine as of this evening. Car has 66k miles.

Okay, so an update... The car wound up sitting at the shop for a couple of weeks while they cleared up previously scheduled work. The mechanic initially heard the rattle/tap/knock and felt some roughness when the engine was running, so they determined that pulling the intake and valve cover(s) would be necessary to assess the issue. When they went to pull it into the shop today, there was no noise, no miss, no performance issues. He asked me to come over and drive it for awhile, which I did. It ran fine, but still had a CEL, which was thermostat-related - apparently a common problem with the 3.6 (he says he sees it a lot on Jeeps). The thermostat issue would account for the original CEL with no symptoms. So that's being taken care of and I'm having them change the oil as well, even though it isn't due yet. We're going to hold off on pulling the intake and VC, because they say a bad lifter/rocker would likely not make a racket and then go silent. I'm still baffled, though. I read somewhere that a cam phaser can suddenly make that kind of noise and then stop just as abruptly. Has anybody had that happen?

Will do - it was flat-bedded over to the shop earlier today, before I saw your post. It might take them a couple days to look at it. I don't know why, but I keep thinking rocker issue - a lot of clattering on startup.

I was heading home one rainy night last week when I was suddenly alerted by the always soothing chime of the CEL (2015 CPO R/T 67kmi, V6, AWD). There was no accompanying symptom - no noise, roughness, hesitation, limp/slowing, etc, just a steady CEL. I quickly scrolled through the screens, checking temp, oil pressure and whatnot, but nothing seemed amiss. I continued home (another 15 minutes on the highway), and when I arrived, I shut the engine off and stepped out to check for a loose gas cap or other obvious cause. I restarted the engine and immediately the CEL lit up again. I shut down and went inside, figuring I would have my mechanic check it after the holiday. I started the car periodically over the next few days and the result was the same - it was not driven any further. Today, I decided to take it to get looked at, and upon startup there was a loud knocking sound from the engine. I shut it off and tried again, with the same result. I checked the oil and it was at the SAFE mark. It's always been serviced by the dealer and not due again for another 3k miles. After a short conversation with my local mechanic, I elected not to drive the car and will have it towed the half-mile to his shop in the AM. So - has anybody ever run into this? I'm sure I'll be finding out what gives soon enough, but just curious...

Got it up on a lift today - blew compressed air into the drain hose, and... Journey AC Drain.mov

Thanks for the link!

2015 Journey R/T, V6, AWD. After a couple of days of unusually heavy rain, I noticed a sloshing sound on left turns. It seemed to be coming from the passenger side cowl/door area. Upon closer inspection, the door showed no sign of retaining water, so I removed the cowl fascia pieces and felt around inside and it felt dry. I moved to the interior and felt wetness in both the driver and passenger footwells. I took another ride and turned the blower motor up - on left turns, I could hear what sounded like water hitting the blower wheel in addition to the aforementioned sloshing. I feel pretty certain that a drain got clogged from all the rainfall, since I never had any issues prior to this and the AC always seemed to drain as you would expect. I have to get it up in the air to look for the drain hose - does anybody know where it is relative to the underside of the car?
