While driving the 4x4 feature wants to partial engage causing a grinding noise in front axle and when you let off accelerator it slows the speed quickly. At times only way to get it to quit is to stop and back up to make it stop. The problem is caused by loss of vaccum. This causes damage to the front brake rotors and drums and is a intermerminate problem and has been in shop before and reported numerous times.

On several very recent occasions, the above listed 2020 F150 has randomly shifted down to 1st gear from 10th while on the highway resulting in sudden loss of power and extremely high RPM. Had this occurred in heavier traffic, there is a likely chance this could have resulted in a serious accident because of the speeds involved.

10R80 Transmission issues with Ford F150. Many Ford customers in different US states have been experiencing the same transmission issues without Ford fixing them. My Ford truck has been experiencing rough, jerky gear changes and hesitation with acceleration over the past 4 years.

The transmission has been completely overhauled and Ford service advisories have been completed.
