This issue came up a few says ago just before heading out on a trail ride. While waiting at idle my dashboard light flickered and then momentarily turned off and back on, doing the same with radio and AC fan, also causing the engine to drop RPM and run rough. this happened once until later on.
During the trail ride later the same day after going through several deep water crossings the issue repeated itself again, often several times in just a few minutes. This issue would continue regardless wether or not i was in deep water, out of water, idling, or moving. Although the issue was more frequent when in water or just after getting out of water.
In one instance my dash turned completely off bringing the radio and AC with it, only to not turn back on his time. I do not recall wether or not the engine turned off. This time after restarting the Jeep i was met with a check engine light, pulled a code P0750 (Shift Soleniod A Malfunction) out of the in dash code reader. I turned off the jeep and checked all fluids for water(none), and if the canbus/pcm was wet (it wasn't). Decided to continue on the trail ride. The issue continued to repeat itself but with less frequency, it would not occur again for the ride home.
After arriving home from the trail ride and restarting the jeep, i found the check engine light to have gone out, no codes pulled.
Several days went by without the issue occurring until today, the speedometer reset to 0 and back to actual speed while driving, the dash turned on and off while idling, and when sitting at a stop light, the dash, radio, AC, and even the engine completely turned off. Everything worked fine after restarting, no codes pulled, no check engine light.
The jeep is going in to the dealership on June 3rd but would like to hear your thoughts on what could be the issue, things to try, or anyone else that is having a similar problem. Afraid that the dealership won't fix under extended warranty due to modifications.
