Our inverter went bad after a few trips too. Fixing that is a quick job. If the dealer has the parts in stock it’s a couple hour fix, if not it will take 7-10 days for the parts to arrive. As for the water leak. That could be harder. It did not sound as if it had been raining but if it was raining at all then they may say it was part of the envelope that was compromised. If not, they will have to track down the internal water leak which may take some time, especially if the dealer has low water pressure and the CP had high water pressure. Pressure regulators even relatively new can fail. So it may have something to do with the CGs water, and hard to duplicate at the dealer.
