2021 FORD EXPLORER Forward Collision Avoidance Adaptive Cruise Control Problems

As I am traveling on the freeway or expressway, when I have cruise control active and I am in the far right lane the vehicle suddenly changes to the speed of the frontage road dropping my speed from 65 or 70mph down to 40, even tho I am on the expressway. It almost caused me to be rear ended because of the sudden drop in speed.

All of the ADAS along with the brakes of my vehicle fail. The dealership failed to inform me of the recalls prior to purchase. The dealership in town shows all of the parts in stock in their parts department but claim not to have any parts available. When I called, I was given the runaround then sent to a voicemail. When I showed up to the dealership they stated they can only order certain amount of parts and I wasn’t on the list yet was told over the phone I was placed on the list on May 22 2024.

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...

Vehicle loses power while on freeway when 4WD, Pre-Collision Assist, Hill Start Assist, and other warning messages display. Vehicle lost power approximately 5 times while registering message, but messages have displayed approximately 40-50 times in the past week before being services. Vehicle dealership repair facility inspected and diagnosed a bad 4WD module.

While using Intelligent Adaptive Cruise, the vehicle suddenly thought the speed limit was 85mph and quickly started accelerating. Confused, I hit the brakes to stop the acceleration. I have uploaded a photo of the dash that I took showing that the system read the speed limit sign as 85. I saw no speed limit sign in the area, so, I have no idea what prompted the system to change speed. I was talking on the phone via Android Auto and using Waze, via Android Auto, USB direct connect. The only other problem I've ever had with this system is on interstates that have specific Truck speed limits in West Virginia. There, sometimes trucks have slower speeds and this system picks up those truck speeds and decelerates/brakes to comply. While it can be overridden in the moment, the next time it sees such sign, it slows again. This sudden deceleration poses...

Adaptive Cruise control reads the overhead electronic posted 65MPH speed limit signs as 85MPH. This only occurs when traveling on I-670 eastbound between Leonard Ave and I-270 on the east side of Columbus Ohio...This section of highway was recently upgraded with "Smart Lane" overhead electronic signs. The dash on this vehicle shows the posted speed limit at all times, but if the cruise control is on the vehicle with automatically go to what it reads and in this case goes to 85MPH! I have driven this vehicle over 5000 miles in 4 different states and this situation only occurs at this particular locatiion. I have contacted State of Ohio, Department of Trtansportation and discussing this issue with Drive Ohio representative Luke Stedke ( [email protected])
