Have a new 2020 Honda Fourtrax Rincon, 620 miles, been in the shop 3 times, the PDM just stops, resulting in it loss of 4 x 4, the engine shuts off when put in reverse, speedo races up and down even when standing still. Any suggestions? Honda does not seem interested in helping/fixing even though still under warranty. Suggestions? Any anyone else have this problem? The Honda tech has no answers. Thanks.
