2022 Georgetown GT5 Low Speed Issue

[edisit]

Took the rig out for the first shakedown camping trip. While accelerating on to the interstate the rig slowed down and I got a low power warning and brake on notification. I checked the park brake and it was off. Drove about 10 miles to my exit with no other issues until I got in the campground. When coasting at 5 mph or less the rig would start jerking but stopped when I accelerated. Any ideas on what might be going on? We made it home but the issue continued when driving 5 mph or less. I have Ford towing it to a local dealer to check it out on Monday.

I believe the "Brake on" notification refers to the service brake (pedal being depressed) rather than the parking brake. When this occurs the ECM disables (maybe not completly) the throttle. By chance did you possibly have a mat or similar touching the brake pedal. It happened to me once when I had foot unintentionally touching the brake pedal while depressing the accelerator. This is a new feature implemented on the 2020 F53 V8 chassis.

No we do not have any mats just the flooring that comes with the rig. Maybe I accidentally touch the brake while hitting the accelerator. That only happened once then everything was fine until I slowed down in the campground then the rig started jerking until I pushed the accelerator again.

What caused the jerking?

The emergency brake on the rear axle was fried from the factory. Forest River ended up paying to have it fixed even though it is a Ford part.

Summary

Some 2021-2022 F-650/750, 2020-2022 Motorhome/Commercial Stripped Chassis vehicles built on or before 20-Sep-2021 with very low miles may experience parking brake drag. This condition typically occurs in less than 3000 miles (4800 kilometers). This condition may be identified even with the hand or pedal actuator mechanism disengaged. Inspect the park brake system for damage and replace parts as required per Workshop Manual (WSM) Section 206-05. If no damage if found, adjust the park brake cables and the park brake shoe adjuster per WSM, Section 206-05. For claiming, use the applicable labor operations of the Service Labor Time Standards (SLTS)

Say is this an intermittent problem? I thought I felt a drag but no indication on the dash, and I haven’t felt it since, at high or low speeds. I have the ‘21 chassis with a 12/21 build date.

There is a ford recall for the parking brake cables adjustment or replacement. You should check the f53 ford recall list.
