Is there anyway to do away with that ludicrous battery drain warning when parked, with the only drain being the radio, and Acc position is On?

After driving a few hundred miles, mostly at 80 mph I have to believe my battery is as fully charged as possible, I then pulled into a truck stop, got a cup of coffee (that could have been used to pave a road) and tried to sit in the Tucson listen to the radio and relax but that every 30 seconds the beep and the reminder to start the vehicle, came close to me pulling my handgun and placing a bullet into the info screen.

If this battery is such a POS that it cannot run a radio for a few hours before draining, I either need to dump this vehicle or get a larger battery. And other than this stupid warning, I like the vehicle.

I would understand if the voltage had dropped to around 11.8 V but I'm sure it still had to be well over 12V after such a drive and only a few minutes of listening to the radio.

Even if it was 19 degrees outside I was comfortable and even though wasting fuel has never been a problem with me, in this day-and-age, idling a car for fifteen minutes while I drink road tar and try to relax is ludicrous and should be made illegal by some environmental group.

Someone at Hyundai engineering needs to get the computer programmed to only turn on this warning after the battery actually drops to a certain level (approx 11.8 volts) vs. just having the ACC position picked while sitting in the vehicle.

I know one thing for sure, this vehicle will never be used as a stake out vehicle by law enforcement; idling vehicles draw attention

If not, then I apologize. I'll let the post stand for the hybrid guys. The hybrids only get a 15ah 12V battery. I think the pb-acid in the other models is at least 45Ah.

No, not a hybrid, no need to apologize; I should have noted the drivetrain.

Yup, just manually set the parking brake when you are parked in Accessory mode and the battery drain message will be turned off. They had to give you a way to go to a drive in movie and have acc on without having DRL lights on.

Even if the car auto engaged the parking brake on an incline, there is till a difference between the auto-engage and you manually pushing the parking brake button once you are in ACC mode.

Took a while to figure it out but one warning it's easy piezy!

I'll give that a try, if it works as you say (no doubt it does) it will be great. Thanks....

DOES NOT WORK. Gave it a try this AM, idiot message continues to disturb. Guess they don't care about drive in movies. (Actually have a drive-in theater about 15 miles south of where I live, not that I have visited it, but drive by it.)

Called Hyundai, told I must make a dealer complaint. So, having to go to Lowes I took the drive into the dealer and as expected and what I told the person at Hyundai, it will take a software update and yes, the dealer wishes they would fix it since I am not the first to complain. In fact, my salesperson complained about it a year ago.

Called Hyundai back and wondering if they go out of their way to hire those with no brains or is it just the luck of the draw.

However, when I noted I would contact environmental groups in how Hyundai wants me to add carbon to the atmosphere for no reason other than someone has no idea about how ludicrous this message is unless the battery volts drop below approx. 11.6. suddenly, I got forwarded to a supervisor or something to that affect.

She promised to look into it and she actually gave me the impression there was something between her ears; other than air.

Thanks @Bookworm. That worked perfectly for me.

For those who are unable to make it work (@f5Idaho), my steps were as follows...

Note: Park brake was already engaged, manually, after the last drive.

1. Entered the car, driver's seat, and closed door.
2. Pressed the Start button, entered Accessory (ACC) mode.
3. Dismissed the standard warning on the entertainment screen.
4. Selected Radio - radio now playing.
5. Waited a short period and the battery warning ding sounded and message displayed.
6. Pulled (engaged) the Park Brake button.
7. Listened to radio for seven (7) more minutes without any battery warnings - or any other warnings or messages.

🖖

I'll follow those steps in about an hour,

My experience in red....

Did NOT work on my '23 Tucson! Just gave it a try at the local grocery store lot and froze my Tush off doing this experiment. Wanted it to work, but it didn't.

• Entered the car, driver's seat, and closed door.
• Pressed the Start button, entered Accessory (ACC) mode.
• Dismissed the standard warning on the entertainment screen.
• Radio On
• Warning sign appeared,

• Waited a short period and the battery warning ding sounded and message displayed.
• Pulled (engaged) the Park Brake button.
• Three minutes later, IP went off and interior lights came on, not sure why, it just happened, being all LED not a big drain on the battery for the short period.
• Approx. 30 seconds later interior light went out
• A few minutes later, radio went OFF
• Process started again. Same results about six minutes later.
• THIS IS BS. ONLY VEHICLE I HAVE EVER SEEN WHERE I CANNOT PLAY THE RADIO FOR AS LONG AS I WANT UNTIL THE BATTERY GOES DEAD AND THE BATTERY IS FAR FROM GOING DEAD AT THIS TIME!

Message on the display, REMAINING TIME: 5 minutes after that display is displayed is correct.

Could be a difference in programming from a '22 to a '23.

I've said all I have to say on this subject. I am in discussions with Hyundai at this time in regard to this * .

Dealer says it is normal, not the first person to complain. As to whether the seat belt was buckled? I would say yes since it is second nature for me to fasten the belt upon sitting in the vehicle, so actually thinking if it was buckled is impossible. I believe it was since when the test was over I drove away. One other reason I believe it was is I cannot place the key in the vehicle and start the car, I believe it must have a seat sensor to tell the computer there is a butt in the seat. However, to be sure, I will try it in the next few days and make sure the seat belt is buckled. However it will have to wait for a day or two.

 

[f5Idaho]

Need to correct what I said, I could not place the vehicle in the ACC position with the key in the cup holder and reaching inside via an open window. Only tried it once. Might try it again, but not for a few days. It would be impossible to start the vehicle from outside unless I had a piece of wood to apply the brakes.

@f5Idaho, in post #19 you uploaded a photo of your center console screen. This photo contains two (2) warning messages.

1. The red panel at the top with "Battery Discharge Warning" message.
2. The large warning message window in the middle ending with the "Time Remaining: 5 minutes" message.

The only warning message I have ever seen regarding Battery Discharge is the red one at the top. That is, I have never seen the large warning message window in the middle.

This got me thinking.... Do you have any other devices plugged in to the car? Perhaps connected to any of the USB ports, the 12V (cigarette lighter) ports, or a device connected in some other way that would draw power from the battery when in Accessory mode? Something like a third-party alarm system, camera system, etc.

NOTHING else is plugged in. I do have a dash cam but still sitting on the work bench so that might cause some problems in the future. There is a USB in the port filled with music, but not in media mode on the radio. And even so, the drain would be too low.

I guess some don't understand my problem. THIS MESSAGE IS LUDICROUS, STUPID, UNNEEDED, ETC., ON A VEHICLE WITH A FULLY CHARGED BATTERY. Once the battery drops into the 11 volt range, I might be able to understand. But this tiny four cylinder should be able to start with about 11.6 volts. Heck, from experience, I have started a 6.6L duramax at a battery showing 11.4 volts and it not only has four more very large cylinders, the starter motor is draws a heck of a lot more current than the one on the 2.5L.

Discussing this with Hyundai, they need to offer a way to shut this message off, or give a person an option....ON, OFF, or ON when the vehicle drops to the 11 volt range. Three choices. It makes NO sense to not allow someone to shut it off when they give you the choice to shut off some safety features.

The biggest factor is, senseless idling of an engine has some legal repercussions in over 31 difference states (USA) and in one state, under certain circumstances idling a gas or diesel engine over two or three minutes in certain areas can get you a ticket.

And this car has the Idle stop and go feature to save fuel; however, at least on my vehicle, if I want to relax at a rest area or truck stop of just on an exit ramp for 30-45 minutes with the radio on I will have to push the **** button every five minutes and waste fuel and pollute.

Just wondering how the great green lobby will love this feature on Hyundai (maybe Kia too). Does Hyundai really need more bad publicity? I like the vehicle, but I am planning on a three month trip this summer throughout the USA from Idaho, to the Fl Keys, up to Maine, and back home, with many stops in between in many states. I will be traveling easily 600-800 miles a day, I will want to stop about every two hours, get out walk around, go back and get a 30 minute power nap WITH THE RADIO ON, then get back on the road. With this feature, it cannot be done. This is how I do my traveling now since I hit the 70s and I don't plan on changing for my safety.

Not much else to talk about, I've tried all different ways, except standing upside down on the seat with my legs sticking out of the sunroof and that **** message appears, and the radio shuts off after five minutes.

I call it BS regardless of what others think. One person at Hyundai thinks I want them to purchase the vehicle back...I DON'T. **** I have two sets of tires (odd size on this vehicle too), I have invested in many options just for this vehicle, I have added sound proofing to the cargo area, etc., so I want to keep it, but I want that stupid warning never to appear with over 12 volts.
