An update.
A 4th head unit went in today. I also replaced the cruise control switch twice and today the Throttle Sensor Assembly.
I know there is more but ish......
Am I the only one or is everyone else just fixing and not saying anything. 
You are not the only one. At 8,000 km I had new crank, rods, pistons, rings, and lifters. At 9000km a new clutch master cylinder.
Recently at 17,000km new rocker gaskets due to leakage.
A couple weeks ago at 20,000km I was replacing the plugs before a trip and the rear cylinder threads came out with the plug. I believe due to the heat from the engine the plugs would have been a problem no matter who would have removed them. This was on a Wednesday and departure date was on the Saturday following. The dealer was able to fit the repair in and charged me $800.00 for removing the head and putting an insert in. Says he will try to get warranty for me. We'll see !
Also one of the exhaust studs broke when the tech was dismantling everything and that was covered under warranty.
As you can see I am living the nightmare with you. Could it be a Canadian thing ? LOL.
