I have a 2019 Honda Pilot Elite with about 10,000 miles on it. A few months ago, it started making an unusual noise that would last about a second and would happen every 3 or 4 minutes. It didn't do this until about 5 or 6 month into owning this car. Now it is doing it constantly. The dealer kept the car for a month working on it. Two different times the told me they couldn't duplicate the problem. Both times, I came in and drove it with a technician and easily duplicated the problem. They narrowed it down to the A/C. The have twice "cleaned moisture" from the system and they replaced an expansion valve. I called Honda USA and opened a case. After 2 or 3 calls, THEY told me they were having trouble with the dual-stage compressors. So, I set up an appointment for the dealer to replace the compressor and emailed Honda USA. Today, I got a call from Honda USA saying they have determined, "the car is operating normally and no repairs are required." Let's see: it didn't do it when we got it, it has steadily gotten worse, and now, because they can't figure it out, it is operating normally. I told them I was taking it to a repair shop who knew what they were doing to get an accurate diagnosis of the problem, and sending them the bill. Of course they said they wouldn't pay the bill. So, they can't diagnosis the problem and I KNOW there is a problem and it is under warranty, but I'm just supposed to live with it. Absurd!!!!!
