Service Brakes Related Problems of the 2023 Ford F-650

Service Brakes problem

Picked up the brand new f650 rollback tow truck from the dealer in ohio. Traveling back to California with a chevy yukon 2wd on the bed. Approx 200 miles from the dealer the "service advance trac warning appeared on the dash. The traction yellow light and wrench appeared on the dash. I was traveling down the highway. I called my dealer in California to ask what might be wrong. My dealer told me Ford was having a problem with the system and do not have a solution at the present time. However it should not be a performance issue. Continued on with the vehicle. As it turns out not only is it a performance issue its also a major safety issue. First noticed that when pulling away from a stop light vehicle struggled to get moving. Driving on flat ground the vehicle would get up to speed but slowly. The real danger is when braking. After you touch the brakes there is no throttle response to get going again. The accelerator was as good as dead. This happened at 76 miles per hour on the highway. Coming down a mountain at 76 in the number 1 lane. Loaded semi truck behind me speed limit 80 . At bottom highway sweeps left as goes back up hill. I had to press the brake due to a slower vehicle in front of me, I pressed the accelerator and no response. Continued no response as the semi behind me was locking up his brakes to avoid rear rending me. Vehicle reduced speed to 40mph still no response. I darted across the other lanes to shoulder of the road. No response from accelerator. Turned truck off and restarted. Truck sluggishly moved and got up to speed. This was a extremely dangerous situation. My solution to getting truck to California. If I could engage the cruise control when the truck hit 32 mph I could drive truck with the cruise control using the + and - for speed. This would work. However if you hit the brake. Game over. No throttle response. This is the most dangerous truck I have ever driven.
