In late July, we purchased a 2016 Chevy Tahoe and a few days later, we hitched up our Casita and headed for Canada. The Tahoe has an "information" screen below the speedometer (not a feature on the 2009 Tahoe that was traded in). As soon as we hooked up, a message came on the screen "Trailer Connected" followed by "Check Trailer Wiring" accompanied by a series of four chimes. The sequence repeated approximately every 10-20 seconds. I checked all the lights and they were working and the brakes appeared to work as well. Drove to the Chevy dealer and was told that the car was OK and that the trailer plug was bad. Went across the street to a trailer dealer and they replaced the plug. We headed down the interstate for a few miles and the messages and chime started again. Thought it might be a loose wire in the umbilical cord and sometimes I could arrange it and the chime was quiet for much of the day, other days, it went off almost constantly. It could happen any time but was especially frequent on rough roads. Fifty miles from home on the return trip, I stopped for fuel and the message changed to "Service Trailer Brakes" and the chime was silent for the last hour of the trip.
When we got home, I took it to the dealer for service and asked them to silence the "dinger" but they said it could not be done.
Took the Casita to the RV service shop this morning ("dinger" went off several times on the drive in) and they went over the brakes and called to say it was ready to go. Hooked it up and the "dinger" still went off. Unhooked and left the Casita at the shop.
So, questions are:
1. Has anyone else ever experienced this situation with a late model Chevy?
2. Any suggestions on how to test the trailer electrical system to find the problem?
3. Failing one and two above, anyone know how to silence the chime?
Thanks for any help.
