      I'm not sure. I've got a 2013. Maybe someone with a 2016+ with knowledge of the maintenance schedule will chime in.

      Thanks everyone. I went ahead and gave the dealership the go-ahead to order the part and do the work. I really appreciate everyone chiming in on this, and hopefully this thread helps someone else in the future should they experience what I...

      Just off the phone with the service manager. The shop foreman was assigned the task of figuring out what the issue is. He apparently will clean corrosion when he can, but says he cannot this time. The part (I don't have the part #) is $309 and...

      Update: Just heard from the dealership. They say I need a new harness that goes to the AHC pump. Apparently this harness is corroded. Is it possible to save this harness, or do I need to proceed with the repair?

      Yikes! When my issues are all said and done, I'm going to drop the spare tire, pull the access panel, and check things out in greater detail (when it warms up here, that is), including inspecting the AHC fluid. I'm really intrigued by this...

      @1world1love thanks for the intel. I’m at the dealership now. Set traps under the truck in the driveway last night and found two empty (but still set) traps this morning. I really like the trap under the hood with peanut butter and sunflower...

      Thanks @lx200inAR. I spent some time reading up on how to run Techstream on a Mac last night, and am going to dig into it this weekend. Between the Veepeak with the Toyota pack, as well as Techstream, I should be able to do just about anything...

      I suppose I could do that. My only fear about rat poison is that they usually go someplace and die and the corpse rots someplace that you can’t find them. That’s why I went with traps baited with peanut butter.

      Update: I got the ScanGuage II out of my 80 series and plugged it into the LX. It said there are no codes. Seems crazy considering there is an AHC warning on the dash. So I ran to the local auto parts store, thinking maybe my old ScanGuage II...

      Funny you mention this, as I'm starting to believe that it was the rat again...

      There was at least 1 bad batch of the AHC fluid, and I believe that they were the 1L sized plastic bottles. There is something about there being some coagulating or it getting sludgy in the bottles, which in turn keeps the system from pumping...

      I read that about the Colorado Springs Lexus dealer as well. I have them in mind, but it's a bit of a haul to get to them from Boulder.

      I ordered the code reader last night, the Veepeak, but it won't be here for a few more days. I may grab the ScanGuage II out of my 80 series tonight and see what I can find. Robbie Antonson is in my neck of the woods, and he's really the...

      Chapter 2: Two weeks ago I get in the LX, fire it up, and the dashboard blows up like a Christmas tree. It's running, but the CEL is on, and the 4Lo light is blinking. I pop the hood, and there has clearly been a rodent in there. I suspect...

      Chapter 1: In October of 2021, I was due for my 60k service and an oil change. Turns out, the AHC should be serviced at this time. I called the Lexus dealership to schedule, and just so happened to have the head of the service department on...
