Yep welcome to the club. My truck has been at the dealer since 3/1. You’re the first ‘23 I’ve read about though.
After a week of driving on the highway with no issues, it happened again today. Had it towed to dealership and there it sits until Monday.
I had mine back for a week driving to and from work with no issues after being at the shop when they could not duplicate and today it happened again about 500 miles after the first time. Glad it didn't happen while I was in the mountains.
That sucks! I'm filing a report with the NHTSA to make sure this issue is being tracked.So I just got hit with this junk today. Had 10k trouble free miles, got my service done including a couple reprogramming recalls and sure enough my truck died on the expressway less than 1k miles later.
2023 Lariat Hybrid deliver Feb 2023
I had all those updates done to my 22 lariat hybrid with 22k miles. Now at 26k miles no bad issues. Had updates done remotely in my drive after having noco genius 5 maintainer on 12 volt over night. (Insurance that 12 volt had at least 12.2v in case tech didn't put 12 v charge current on truck during update. Rumor that less than 12.1 soc can hinder proper updating?). Random acceleration sounds to me like cruise control (maybe only active cruise?) is on and vehicle in front of you changes lanes so your cruise automatically resumes,????. Probably not that since stepping on brake should turn cruise off. BUT IF UPDATE WAS NOT SUCCESSFULLY COMPLETED = who knows. I would try to get dealer to reapply all updates in case they did not update properly. Next I would have my noco maintainer on 12 volt all night every night to insure that all sensors were operating as well as possible. Should NOT HAVE TO DO THIS BUT!!!! Good luck....
Welp. Truck cleared itself this morning when I was driving back from daycare. Also shows no issues in Ford Pass now. I'll still scan it once the reader arrives.
I would bet that 12v recharged enough so that startup test of sensors completed properly with passing voltages, etc AND enough no fault cycles occured to clear the problem has occured flag. Remember that driving in LOW will maximize Regen braking and also use the hydraulic brakes as needed. Think of it as computer controlled brake riding, being sold as a downhill coasting control but try it in stop and go traffic from 0 up to whatever mph you want. LOW also runs the ice much more as it rapidly fills the HVB to soc 70-72% and uses engine braking prior to using hydraulic brakes. Will not directly force more rapid 12v charging but can possibly reduce draw on 12v. A THOUGHT= Maybe when dealer hooks up computer to test truck and cannot replicate problem the 12v now has adequate soc OR the computer also places 12v on to bus! Shouldn't be that way but it's a logical possibility.
