I am having this issue as well. I have Solar chargers and Lithium batteries, so the battery voltage is definitely higher than the trucks. On a trip back from Disney I had a major tire blow out on my 5th wheel that blew through the floor of the trailer. Then an hour later a second one on the other side also causing damage. I had been having trailer wiring issues flashing through the trip and lost trailer brakes several times before all of this. I thought there must be an issue in the wiring if the trailer. I went to the repair shop today to pick it up and the trailer brakes didn't work, I tested before leaving. The trailer had been sitting on the lot for three weeks charging with solar panels and was completely topped off. I left the trailer with them to check the brakes assuming there was an issue as I had recently pulled a car haul trailer without any issues. The car hauler didn't have a battery and it worked great. Now after reading this I realize exactly what is happening, and I am very concerned that there hasn't been a recall. Many RV's are converting to lithium and for great reasons, they are fantastic batteries! So maybe GM is not really in touch with their user community, or research future trends in the market, or very concerned about their safety. A brake controller shouldn't fail or cutoff for a fault for any reason, especially when safety is involved. imagine this happening when going down a mountain, or approaching a traffic jam. Scary
