2020 Ford Explorer st-about 55,000 miles. Dealer: preferred Ford in grand haven, mi. Issue is sometimes a multitude of warning lights would come on when traveling. They include shutting down the cruise control when in motion, the forward collision sensor would stop working, all wheel drive and hill assist lights would come on and stop working. This happens whether a short trip, 10-15 miles into town, or on a longer trip. Only way to potentially reset it was to stop, turn vehicle off for a minute or two and restart. Sometimes this worked and sometimes not. This is a safety hazard when operating on a roadway, usually at highway speeds, especially in winter road conditions or an occasional trip through the mountains to the southern states. Had a computer update, which cost $540. 00, still not solve it. Finally able to get into dealer with all warning lights activated. Dealer stated has to do with drivetrain. Now today (8-3-23), was advised by dealer a new Ford engineer internal service memo stated that is not the total fix. Total repairs cost is in/around $2000. 00. If Ford knows this is an issue and with the many Ford Explorers on the road today, this needs to be addressed so the consumer can have confidence in driving their vehicles.

My 20 Ford Explorer has experienced twice where the speed limiter (acc adapted cruise control)-(ssr speed sign recognition) reads the speed limit signs incorrectly. Posted speed was 65 mph and it increase speed to 85 mph. I was driving thru columbus ohio, on i670 going ne, starting at the leonard Ave exit to i270 (to exit 10b sr161). I don't drive here often; the first time was Feb 23 & then March 16 (photos attached) in the same exact location. On both occasions, the speed sign (speed sign recognition) on the dash read 85 mph for at least 3 miles before correcting itself to the posted 65 mph speed limit. On Feb. 23rd, I was driving approx. 65mph with the acc set. The car accelerated quickly and not realizing at first what was happening, I pressed the brake to slow down (I was going over 75mph). The icon on the dash (ssr) read 85 mph which is 20 mph over the posted speed limit. The second time when the car sped up, it slowed abruptly due to a car crossing in front of me (within the 4 car following gap setting). Both times I had the cruise set (acc) around 69 mph and the car speed increased or tried to, to 85 mph before realized what it was doing. Either time I could have caused an accident or been cited for speeding. I have video of the incident if needed. Why I'm submitting this to you. . . I called my service department and it was suggested by them to check my exterior sensors and clean them (wash my car) and contact Ford corporate. I contacted Ford corp. Via the 800#, I was instructed to call my service department to have the car looked at. I also contacted Ford via their facebook site. They requested personal/privy information to be sent thru the social media site but wouldn't give me a secure email to submit to. So I'm at a loss to who can help resolve this issue.

Cruise control can not be disabled by pressing brake pedal. Requires passing steering wheel button to turn off. Also "pre-collision assist not available" message comes on dash every time vehicle is started.
