Mine did a sucessfull OTA update for the very first time and it was the 22S17 for the Trailer module. Had the truck in the shop few days later and they did the update again. They couldn't explain to me why it had to be done again, other than the OTA didn't work after all.I have my truck set to receive any OTA. Set for 1 AM 7 days a week. Unfortunately, I have yet to receive any OTA down loads.
I got the trailer brake recall done by taking the truck to the dealer.
