New Samsung S24U won't charge wirelessly. I put it in the slot, it shows charging for a few seconds then goes to the yellow warning triangle. Tried without the Otter Box cover, no help. My S21U didn't have that problem. Anyone else with the S24U have this problem?

Does it charge wireless in another vehicle or at home? How discharged was the battery when you tried? Most new phones use optimized charging so they may not charge past 80% to increase battery life. While I don't have a Samsung phone, our 23 Tahoe will charge both my iPhone and the wife's iPhone just fine as long as they are discharged below 75%.

As far as I am concerned, wireless charging in these refresh trucks is useless.

 

Unless you have the ONE phone GM used to design the system, which is probably the first phone that ever had wireless charging and has not been made for ten years your phone will not sit in the massively oversized slot correctly.

 

You will need to find out how high off the bottom of the slot and how close to centered you have to be to get a solid charge, and then make an adapter to fill up the excess space to have any chance of it ever working.

 

My current best setup is 1/2 inch from the bottom and evenly centered, charging port down, screen up, on my Samsung Z Fold 4, but it's not foolproof.

I may buy some of these and use one for a month to make sure it's a solid place, then have someone 3d print me a filler.

in my 2024 1500 using my s24 phone , I have to slide it into the charging pad on my console with the top of the phone facing the rear of the truck, face up. this works on 2 out of 3 s24 phones. The 3rd one the case is too thick to waork on any wireless charger.

Hope this helps

My Sierra is the only vehicle we have with wireless charging. At home we use a standard charger. My previous S21 worked fine. My wife's S21 does as well. First try with the S24U it was at 62% charge. Thanks for the info.

Depends on the phone, the placement of the phone and the phone case. If I keep my case on, it won't charge. If I remove it, it will charge.

I had this fixed in my truck. Go to the dealer with the no wireless charge complaint. There is a service bulletin about it. There are several different modules that can only be identified by disassembling the entire center console and getting to the bottom of the wireless module. If it's the first type, they replace it. If it's the second type, it is the correct hardware and it needs a software update to charge Samsung phones. If it's the third one, there is another problem. Mine got the software update and has been working since without issue on a s23ultra. If you look at my previous posts

, you should see the bulletin number to give to the dealer if they can't find it for some reason.

BOBDER41 YOU ARE THE MAN! I just bought a s24 ultra and I work at the damn GM dealership as a salesman, I never thought about trying that but it worked perfectly. Thank you very much !

My S23U would usually charge , but my new S24U does the same behavior that you describe. I need to check it without my case on, but on the S23 you could move the phone around a little and find the sweet spot/orientation for charging. I haven't found the same with the S24 Ultra.

I must have super - charger in my Denali Ultimate. I have a Samsung S22 Ultra and S24 Ultra and both immediately start charging with silicone cases. Top toward front.

My 23 Denali has been hit and miss with my Pixel 7 pro. I got used to cursing at it and adjust it couple times then it seems to locks in.

This post is exactly what I need! Thanks! I am going to try this with my dealership. I have a 2022.5 Sierra Denali and have this charging problem on my Samsung S25 Ultra and iPhone 15 Pro Max. I am out of bumber to bumber warranty but have an extended warranty. I will report back with my findings...

    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
