When towing a 15,000 pound 5th wheel camper at highway speeds, the truck's trailer brake system and stabilitrac system will (without any warning) shut off, leaving the driver without any way to activate the trailer brakes. Neither system will re-activate without first stopping truck, shutting it off, unplugging the camper 7 pin, and then driving about a 1/2 mile. This issue first occurred at approximately 24,000 miles and continues to this day. The truck now has 44,000 miles. Chevrolet has looked at the truck twice, but was unable to determine what the issue is. I have isolated the problem to occurring when I pass under certain low hanging high voltage power lines. There are two locations where the problem consistently occurs when I pass under the power lines in either direction. Replicating the problem shouldn't be an issue.

I have a 2015 Chevy Silverado 1500 4X4 with 5000 miles. While driving to work ( less then 2 miles) my service 4WD system warning came up. The truck is stuck in 4WD can not switch it out. Also while stuck in 4WD turning is very difficult. Called dealership they told me it was safe to drive it in. While on my way to the dealership still stuck in 4WD my check engine and traction control lights came on. The truck started to shack and shifting at random and the RPM were all over up and down. I got to the dealership and checked in they took it for a test drive while I waited. After waiting 4 hours they tell me the engine has issues they don't know what or why and that it will be a few days before they will know anything. So that waiting game begins.

On Monday October 5, 2015, I was driving truck at approximately 60 mph on highway when suddenly all electronics went black and complete loss of power on highway. Luckily, I was able to pull of to side of road. I turned the key to off position (engine was not running) and waited several minutes then turned truck on and it started. The traction light kept coming on and off but the truck did not loose power again-thankfully. I could have been killed or caused a serious accident.

When I put the vehicle in reverse I heard a loud clunk and the "stabilitrak" warning came on and the indicator (cursor) that tells you what gear you are in disappeared. I turned the ignition off and opened the door to reset everything. I started the car again and everything was normal. Driving down the road at 40 mph the "stabilitrak" warning came on again and the gear indicator disappeared. I pulled over and turned off the ignition and opened the door. Started the engine again and everything was normal. Driving behind traffic at 20 mph the "stabilitrak" warning came on again, the gear warning indicator disappeared and the RPM's went to 3000 RPM. I immediately pulled off the road and had the vehicle towed. If the transmission had shifted to a different gear this would have been a disaster.
