tl;dr - Three of our four 2022/2023 R1Ts so far have wet carpets under the floor mats due to plugged HVAC condensate drain lines. One of them was bricked as a result of this issue. The sooner this is noticed, likely the sooner damage can be avoided. It can be hard to tell under rubber mats, which we all have. I'm not sure if this is limited to Gen 1 trucks, but according to the Service Bulletin, it should be. Check your carpets for inexplicable dampness folks!
On July 13th, my father's 2022 Launch R1T (VIN 5852, May 2022 build) started making a constant dinging sound with a warning on his screen that said "Electrical Hazard Possible - Drive to servbice center immediately. Avoid driving through water."
This was on a Sunday, so I called roadside for him (we happened to be together when it first happened). The soonest they could schedule a tow was the following Wednesday. Over the course of the next day the truck went from driveable (albeit very annoying, with the constant dinging), to being completely bricked. We are about to pick his truck up, but so far it has needed an entire HVAC system replacement, a heater core (which I guess isn't the part of the "HVAC system?"), 12v batteries (and possibly more within that system), a high voltage fuse, and I'm guessing some or all of the carpetting.
Before this official diagnosis, a little research seemed to me to indicate that my dad's truck was having tell-tale signs of a plugged HVAC drain line—something that has a Customer Satisfaction Campaign Bulletin for, but I had not yet noticed rumblings about. I didn't think to check his carpets before it was towed off, but I wouldn't be surprised if they were wet.
My truck was scheduled for an August 1st appointment prior to my father's truck throwing this non-driveable fault—it has had an ongoing problem where none of the proximity sensors work, which we think is a failing AXM module (also I no auto high beams, camp leveling, and I can't update my firmware). After a failed mobile appointment earlier in July (to fix the proximity sensor thing), I had noticed that my front driver's side carpet was wet (when I went to clip my floor mat back in, since the mobile tech had been accessing something under there and forgot to), but I didn't really think anything of it. After the incident with my dad's R1T occurred, I decided I should see if my truck still had wet floors. It sure does! Both the front and rear driver's side carpets are soaked under my rubber mats. This also explains the damp smell that's been going on for around a month (my partner and I had unfairly been attributing this to our toddler's car seat—which I had taken apart and cleaned, which now not surprisingly, hadn't helped with the smell).
So my truck (VIN 10264, a July 2022 build) and my dad's truck likely both have this HVAC drain line problem, but neither one of us have been contacted about it. Our heavy equipment mechanic, who drives a 2023 R1T we provide to him, just checked under his driver's side front rubber mat today, and he also has wet carpeting! We have one more R1T left to check, but the employee who drieves that truck has been on vacation—but so far 3/4 Gen 1 trucks likely have this problem, and none have been flagged yet for proactive repair.
My truck will likely need some/all of the carpeting replaced (I am going to push for all since cobbling together carpet in patches as they've suggested they sometimes do—just addressing the effected quadrant—seems less than ideal). This will be my truck's 5th trip to Chelsea, MA (3+ hour away depending on traffic) in just over a year of ownership (we bought a demo with 10k miles on it). My father's truck has been to Chelsea at least four times, though I think this might be his fifth trip. Two of these trips were due to non-driveable issues. If I didn't love so many things about these trucks, I'd be seriously considering trading mine in and moving on... my dad certainly is. I am glad there are some folks on here who have nearly trouble-free experiences, but with our four trucks, we have a combined 12 (or more?) trips to Chelsea in three years (my truck and the other two have only been purchased/leased for around a year). It's getting hard to justify the unreliability, unfortunately, but I keep telling myself that "maybe this will be the last time we'll have to go to Chelsea before they have an SC closer!" This is probably wishful thinking, unfortunately.
