congratulations! You are more than likely experiencing the EXACT same thing I am. Mine currently has 500 miles on it, 200 of which are from driving back and forth to the dealership. If you cycle the ignition like 5-6 times you might be able to let you into the drive to take it to the dealership.

The issue is the CANBUS system. It is like an information highway that allows all of the control modules to talk to each other to include the transmission. The thought they fixed ours, but it is back at the dealership for the exact same reason again. We got them to give us a rental car so that we could have something for the time being. This could take a while to fix. The legit have to go through every ground, wire plug and control module in an effort to find out what the issue is.

Because the errors are coming in and our it would suggest that there is a loose wire or connector somewhere. If you find the issue please post it here so I can pass it off to my dealership.

Have others reported on this forum as well?
You and I are the only ones that I have seen as of yet. Is your dealership within 20 miles of your location? If it is you can schedule an appointment to take it in and then use the bluelink button inside of the car to schedule a tow. They will come to pick it up and then drop it off at the dealership. I recommend starting that process very early to ensure it makes it to the dealership in time.

So all my warning lights/safety features/brake come on as well. I currently have 7 safety warnings. I had my car serviced two times already. The second time the service department kept my vehicle for 4 days and claimed the issue was an air bag module. I had the car returned and within 5 days same safety warnings reappeared. Contacted the dealership and corporate office still waiting for a response….

You are the third known case that I know of. Mine was a junction box in the engine bay.

You don’t know if you want to take it into the dealer? Why not? Rather roll the dice and take a chance of some catastrophic failure while your wife is driving…?

Personally I would take the car back to them to service asap. The Tucson I am leasing is back in the shop for the third time. Every safety warning light is on including the airbag. It’s a safety issue for your family. This a screen shot from the BlueLink. The vehicle had issues at 0 miles and continues to have them. The customer service they provide is horrible so get an early start.

Got mine back, they replaced the junction box in the engine bay. Which I'm guessing is another word for fuse box.
Did the new fuse box fix your issue permanently? My dealership said it was a faulty ABS pump and we waited for a month to get a new ABS pump, and what's worse is that the ABS pump was NOT the root cause. The issue reappeared. Will send the car back next week for more checks.

I have a 2022 Tucson and get the same thing. It's at random but always seem to happen when it has been raining. I have not got to dealership yet on this, I'm waiting to get pics of when it does it.

As I previously posted, I had this occur last month after I started my Limited. Shortly later, the lights went off and it hasn’t occurred again. Other than this one incident, I’m really enjoying my 2022 Limited.

Our 2022 Tucson Limited just did the exact same thing; it has around 7400 miles on it. Will be taking it into our local dealership Thursday to have it diagnosed/repaired. My daughter was driving it when everything on it lit up exactly in the pictures above. Hoping there might be a TSB out on this issue since it seems like there have been several occurrences on what appears to be Limited and Hybrid trims.

I have a 2022 Tucson. After parking the car and locking the doors, so all lights are off, the headlights and taillights have gone on randomly and drained the battery. This has happened two times (battery dead), then we found out issue cause friend saw car and called to say front and rear lights were on. They were off when left the car. Used key fob to unlock / relock, and they went back off. At dealership, and they are searching. Thoughts? Thanks.

I have never trusted the "automatic" headlight setting nor do I trust myself to leave switches in the correct position so, I always switch the headlights to the "off" position before leaving the car. Same with the courtesy lights. In my Honda Element the courtesy lights stay on for 30 seconds or so after I close the door, so I leave those lights in the "off" position also.
