NHTSA Complaint #11489546 — 2022 FORD BRONCO

The 2022 Bronco is listed as being able to be flat towed behind a motorhome and the software allows it to be put into flat tow mode. 49 states require that flat towed vehicles over a certain weight have supplemental braking. When the supplemental brake system is installed in a Bronco with the 2.7 liter engine it stops working correctly after 45 minutes because the electronic brake booster shuts off. This results in the supplemental braking system not having enough power to activate the brakes and can cause a serious accident because the motorhome cannot stop soon enough. Ford issued TSB 22-2210 to temporarily correct this issue but it simply disables the electronic brake booster (must remove fuses) and again leaves the towed vehicle with insufficient braking. Ford claims they are working a software update due out in September 2022, it is now mid October and no recall has been issued.
