My 2015 RC390 will fail to start some times and then displays only JY_1.2.3 on the dash before the dash resets. Usually after the first time it does this it starts right up with the only indication that something did not go right is that the clock reset to 00:00. A typical failure is a wheezy pop from the exhaust, like it fired a partial charge, then dead with the dash showing the JY_1.2.3. This morning is failed to start on multiple tries and kept going through the display of JY_1.2.3 and resetting. I finally got it to start by holding down the starter button through a bunch of these wheezy pops until the engine finally fired up and settled into idle. I then turned it off after idling for about a minute. Once I shut it off it started right up on the next try. It has displayed this wheezy pop behavior over the last six months or so but always starts on the second try.
Any one else have this problem? any ideas as to what is going on?
