NHTSA Complaint #11562894 — 2021 FORD EXPLORER

With the Ford Intelli-Cruise enabled in settings, the vehicle automatically adjust the speed while using the cruise control. The vehicle will randomly, quickly, accellerate to a extreme new speed limit it thinks it has detected. For instance, several times while travelling on I-81, with a 70mph speed limit, the vehicle will think the new speed limit is suddenly 85mph and quickly accelerate to that speed. I have attached a photo of the dash displaying that setting the car set by itself. On the flip side, once on I-81, it thought the speed limit was 35mph and quickly slammed on the brakes to slow to 35mph from 70mph. Both are quickly overridden by the driver tapping the brake and cancelling the cruise control. However, both could lead to hazards to other drivers potentially resulting in a wreck, especially the sudden slow to 35mph on the interestate. The dealership says "Yea, it happens and people complain". I have no idea why the speed changes, there are no road signs or other indications to even cause the system to re-evaluate its settings. Ford says Intelli-Cruise uses road signage and other ways to also determine speed (whatever that means). This is a safety issue that needs to be remedied by Ford. However, without NHTSA enforcement, they don't seem interested in resolution. (This website isn't allowing me to upload the .jpg file, upload button disappears when I click it)
