Towing system malfuncition

I have a 2024 Limited. I recentley towed my travel trailor weighing about 7000 pounds on a long trip. During the trip I kept experiencing Parking support, cruise control, etc all showing a malfunction. Basically all of the electronic support involving the sensors went out. Sometimes is reset by manually activating parking. Other times it did not. Sometimes it reset just by turning off engine and turning back on. This did not happen while on long stretches of driving on Interstates. Dealer checked and could not find any problems. I am using an equilizer weight distribution hitch. Front height is back to where it is when not loaded. Rear has 1 1/2' squat. I have the standard shocks. Not the self leveling. Does anyone have any suggestions as to what might be going on? Thanks in advance. Mike1953

 

Check your battery terminals and clean any corrosion…..this has been known to turn many a tundra into an electrical gremlin

 

Assume you have the trailer set up in the menu, set up when towing, (remember we have set it up every time the truck is started back up) all that jazz?

 

Man if you have one and a half foot (18") of squat you got issues. I also can't make heads from tails what problem you described you were experiencing. I'm guessing the automatic braking from the parking sensors maybe? Sounds like maybe your trailer plug is loose or you might have a short in the trailer wiring that is causing the dash to flash a bunch of warnings.
