My wife just purchased a 2022 Tuscon Plug-in 4 days ago (at $7500 mark up…). 2 days after driving she had a check engine light come on. I turned the car on the next day, the check engine was off but I still took it to the dealer to check. They saw the logged code, told us that it was such a new car they weren’t sure what the code meant but it had to do with valves and after checking them everything was fine and they sent us on our way. She’s now 6 hours into a 14 hour drive with the vehicle down to family and when she came to a stop at the hotel the entire vehicle completely shut off suddenly. Nothing worked, not even the doors. She read the manual and uses the self jump cable under the hood and connected it to positive, the car turned on and said “battery too low, only hybrid mode active” or some similar message.

This makes absolutely no sense to any of us and the 24/7 service hotline was useless and just pushed us to call a local dealer in the morning and hope they can get us in. Not to mentioned they said they won’t cover towing bc the dealership is 21 miles and they only cover to 20.

Does anyone have any idea what is going on with the car, or tips on how to manage this? At this point I want To return it back as it’s already been a problem vehicle with less than a week on it.

How did you make out with this? In my search of all info related to Hyundai's roadside assistance, I found no mention of any distance limitations. It just states that the car will be towed to the nearest Hyundai dealer. Did you question them on this?

My wife went and purchased a mobile jump kit and was able to start the vehicle. She’s out of state and now having to jump it every time to start the car. It’s a total mess. She went down to Alabama with the vehicle and the dealer there said they don’t have the equipment to work on Plug-ins bc they weren’t selected by Hyundai?
I am taking it to our local dealer after I go down and drive it back home with her. They have said they will give us a loaner and see if they can fix the car, but I am relatively confident this vehicle is a lemon.

Not surprising that dealers in states that don't sell the plug-ins don't have any experience servicing them yet. Hope that changes soon as it doesn't inspire much confidence when travelling. One would think that Hyundai would at least make sure that some dealers in all areas could service the plug-ins regardless of whether they are sold in that state. Hope things improve for you.

Sounds frustrating. I wonder if the 12v battery has failed, or maybe the alternator. Hybrid tech excluded, that would be my first guess based on your symptoms

Try leaving the jump starter pack on longer to give a bigger charge on the battery, or see if an auto parts store can test your battery. That's usually a free service and they have lots of equipment to help diagnose issues

Thanks! I will ask her to try that today. It does seem to be having some other quirky electrical issues that make me think it may be a broader electrical problem, but hopefully this could help us get back without having to constantly jump it.

Thank you! I hope so too.

Read page 01-43 to 01-44 of your owner's manual. You have what is called an "aux battery saver" that is supposed use the traction battery to maintain your 12 volt battery. Check to make sure it is activated. If it is activated but your 12 volt battery is dying, your battery may be bad, the connections may be loose or the system isn't functioning properly. There also may be a 12 volt draw like a glove box light or courtesy light that could be draining the battery. I can't believe the dealer hasn't mentioned this as a possibility. There is no alternator, the starter- generator charges the traction battery and the traction battery provides power the 12 volt system.

I also have a 1 month old 2022 Tuscon Plug-in with the same problem. I now need to call for a jump start every-time I want to re-start the car. To make matters worse, I am unable to lock the doors when this happens. I brought it to the dealer today because I couldn't keep it unlocked on the street. Have you learned anymore about this problem and how to resolve it? I am hoping it is something simple that can be fixed and that this is not a lemon. I really love the car otherwise. . . . but it it doesn't start then what's the point.

Well, we took it to them. They kept it for a week and then returned it saying that the battery terminal was loose. Since then we have had no issues with the battery needing a jump every time (exactly what you described, we also couldn’t unlock the doors or do anything when it happened), but…. We got a 2nd check engine light less than a week after getting it back. My wife took it back again, they said they’re not sure why it set the check engine light then tried to blame our Amazon charging unit that we set up at home. We’ve escalated with Hyundai and are likely to just have them buy the car back. It’s a massive pain bc we traded in a vehicle (which I’m sure they made money on) and of course we dont want to go back to Hyundai anymore for another car.
It’s been a real disaster and a joke. The service centers are also a mess… never want to buy another Hyundai again.

For what it's worth, it will not be uncommon for check engine lights to appear on the next couple start/heat/cool repeats after flatting out a battery. Many computers record data over that cycle and will take averages, it may need a few cycles to clear.

At least that's been my experience on other cars. Not trying to apologize for Hyundai, but it feels a bit extreme to want a buyback for a loose battery cable if that ends up being the only issue.
