I had this also after having my new truck for a month. No hard breaking was involved that I know of. It was so bad that I ended up putting ceramic pads on the back and that solved the problem.
Project Farm is a good YouTube channel to root around on for oil testing/comparisons.

Had the truck into the dealer a couple of weeks ago and they replaced the trailer brake controller board and reprogramed. Tried hooking up to 3 different trailers. All trailers disconnect properly and no strange alarms, but all 3 trailers and test plug showed the right trailer brake light...
I have a 2.7L 2022 Lariat that has a whine that I can hear at about 40mph and peaks at about 55mph. The engine is absolutely devoid of this whine while in park and at the same rpms. When I'm at 55mph and about 1400rpm I can feather the accelerator to make the noise come and go. Letting off...
It took a couple of days to clear. I had pulled a few fuses and the negative cable from battery in that couple of days. Have no idea what event caused it to clear finally. My guess is that the software doesn't know how to properly recover from a problem.
I have a whine that I can hear in the range from ~40mph to ~60mph. It only seems to be present when I am at a somewhat constant speed in that range and at about 1400 rpm (+/- 100). If I remove my foot from the gas, the noise immediately stops before any change in speed. It is quite loud at...
I ended up connecting to my 4 pin trailer and and my 5 pin trailer just a little while ago and both trailers connect and disconnect just fine. My only guess of what happened is that when I back the trailer into the water, something shorts or grounds causing a condition that the software thinks...
I crawled under the truck and took a look and didn't see any moisture in the plugs on the backside when the problem was happening. The bumper didn't get submerged when I put the boat in the water. Also check to see if the connectors were tight.
I will try to delete the boat out of the towing profiles. I'm using a 7 pin to 5 pin adapter plug (5th pin is for disable surge for backing up). I remove the adapter when I disconnect the trailer. Thanks!
I did submerge the trailer, but all the lights on the truck seem to be working. When I connected back up to the trailer the fast flashing goes away and all the trailer turn lights and running lights work fine. It's like the software is not sensing the disconnect of the trailer. After I posted...
I recently towed my boat and put it in the water at the marina for the season. When I got home, I disconnected the trailer and parked the truck in the garage. Started truck up the next day and got a few different alarms (Rear Park Aid Deactivated Trailer attached, Reverse Brake Assist Not...
