My 2015 Yukon has weird electrical issues when it rains. The dash says to service front camera, theft deterrent system and airbags and the gauges all stop working. Car will run fine if it starts to do this when driving but if those messages don't go away car won't shut off. I have to pull a fuse but lights still on in car so then have to disconnect the battery to shut off. Sometimes when I get in it to start I push start button and lights come on but all those dash messages come on and then car won't start. But on nice weather days it is absolutely perfect. Im going crazy. Also once in a while for the past year the service side detection sensor message will come on but everything still works when that message appears. Please help! I don't want to go to dealer as I have heard these year Yukons are an electrical nightmare and Im afraid they won't even be able to figure it out.
