Hit a pothole dash lights on

[T4STE]

My 20 jlu rubicon with 8k miles hit a pothole today. Front passenger and the Service ABS and Service Electronic stabilizer went up. It also said service 4wd but when I turned the Jeep off and back on, the onlylights turning on is the ABS and traction control light. From what I’ve looked up it’s a handful of things from speed sensor to corroded abs plugs and vacuum pumps etc. I can bring it in for service until Tuesday cause of the holiday but anyone got this issue? I just got 37’s put on so I will have the shop check the Tpms on the tire for the front passenger.

Check all fuses and relays they are fully seated under the hood.

Definitely symptoms of a faulty speed sensor. Had this on my '15 JLU.

Did all this when I had blown a fuse months back. Similar issue but will check again

Tried resetting the fuses. All seems to be good. Turned the Jeep on and the lights were still on. Started driving it and it went away a minute later. Gonna call this on a freebie. Will keep an eye on it tho

Seems to be the case this time

mine just did exactly the same thing...same warning lights.
I did not hit any potholes at all.
Got 4000 on this 2020 JLU
Pissing me off.

A) check speed sensor.
B) stop driving in new jersey. You don't have potholes. You have craters.

This has happened twice now in my 2021 JLUR. First time the dealer said they couldn’t replicate it. I’ve got it on video both times after hitting a pothole. Has anyone had a dealer fix the issue?

Just a suggestion, check the front axle nuts and make sure they are tight. Seen the same thing on Ford, Chevy and Dodge pickups. As they have the all in one wheel bearing/ABS sensor.

How straight is your steering wheel?

Straight. I haven’t taken it on any hardcore trails and haven’t needed an alignment. It tracks straight as well.
