Got a series of random faults on start-up

[RotorOver]

Got the following faults on a start-up this evening all at once: Powertain Malfunction / Reduced Power, Restraints Indicator Lamp Warning, Hill Start Assist Warning, Pre-Collision Assist Not Available, and Blind Spot Detection with Cross-Traffic. Shut it down and did a re-start, but they did not clear.



I'm guessing it is either 1) software issue 2) a bunch of functions on a common computing module that failed 3) a bunch functions on a common electrical bus that failed.

Hopefully, they will clear on the next start. While hope is not a plan, I'm heading out of town on Wednesday, so I won't be able to take it in until next week if necessary. I most likely won't have time to get a look at Forscan before then either, but I will update if I do.

Possibly add checking the battery and alternator for correct voltage. All you need is a multimeter. Low power can play weird games and there have been a few threads about battery issues.

Check all the fuses and make sure they're properly seated.

Will do thanks guys.

Brought the car in on Monday for the dealer to take a look at it. They are still troubleshooting.

Well, hopefully they can figure it out, keep us posted on what they say.

was it the battery? I've had this issue before in my F250 and it was a bad cell.

Happened in my Gen2 about 2 years ago. Stopped, shut down, restarted and it hasn't happened again.

Talked to my SA near the end of the work day and she says trouble shooting continues. It's apparently not the battery, but a comms issue between components. She said they will need to pull the seat(s) out to continue trouble shooting tomorrow. The dealership shop foreman is doing the work.
