4.2.6 update broke my car

[eire1976]

I have a '22 Premium RWD standard range. Just updated to 4.2.6. Now when I start the car I get a bunch of error messages shown in the video. I've tried shutting off car and starting. Still same errors. I've tried rebooting sync, still no luck. This happen to anyone else?

I've tried shutting off car and starting.

You turned off the car and waited a few minutes before turning it back on? You need to let the system go to sleep

I know you weren't charging, but try this procedure: https://www.macheforum.com/site/thr...ng-service-vehicle-soon-while-charging.26983/

I got the same set of errors. After turning the car on and off a few times, it appears to have resolved itself. I had to drive with 1 pedal drive off, which was a challenging blast from the past, but finally I turned it off and on again at a stop light and everything came back as expected. Hope it resolves quickly for you.

Update: I drove it around a bit without any of the features that were turned off including 1 pedal driving. After going into the store for a bit, when I came back the errors stopped after turning on. Thanks for your help!

One of the key learnings I have over the past year is to WAIT. Wait a day, or two, and drive (if possible). Things aren't done, yet you have no visibility to that.

Literally the exact same thing happened to me Thursday AM on my way to work. Worst part was, this was my first day back in the office in over 3 years and I had to be there! Drove about 2 miles, everything was gone and normal again.

My cars both got 4.2.6 overnight. My car's reverse emergency braking wasn't working when I started out this morning but it resolved itself after driving an hour or so. My wife noted no issues with hers.

I get this pretty frequently even before the update. I resolve it with either a power car off and on, or sometimes just a sync reboot while driving. It is quite annoying though and I would really like to know what causes it. I imagine a dealer appointment would be a waste of time unless it happens to them while diagnosing.

What the PowerUp release notes never tell you is something that all of us who update our cars with FDRS already know....and that is that due to the interruption of communications between modules on the car's network during updates you are likely to get errors the first time you start up after getting an OTA. They normally will clear after a drive cycle, or as in the case of the most frequent message about "Reverse Brake assist not available", about 5 minutes of driving.

Same type of error on our car after the update. I turned it off, back on, put it in drive and then back to park and shut the car off. Next I turned it back on and the Service Soon warning turned off. I also noticed that the front active air vents were open after the update complete.
