Got a new iPhone 8. Was hoping the wireless charging would work in my new 2017 2500 Denali. I can't get it to work unfortunately. If I place the phone just right, I can get it to connect (little green lightning bolt shows up on the display) for about 3-4 seconds then it disconnects. Did some internet research and removed the rubber mat in the charging area and it was easier to get it connected, but would only stay connected for the 3-4 seconds then stop charging. This was both with and without a thin leather iPhone case. I did read somewhere that this GM charging mat is only a 1 amp and that the phone may require a 2 amp connection to charge wirelessly? Just curious if anyone else picked up an iPhone 8 and had tried getting it to work with the GM wireless charger or if there is any "fix" for this.

I have an iPhone SE which does not have the wireless charging but I bought a wireless charging device that was a thin pad that fits in the iPhone case and a charge pad you place the phone on. That worked OK at home but when I tried it on my truck console, it was very finicky and really more of a PITA than a benefit. It took longer to find the sweet spot that started the battery charge than it did to just plug it in and leave it safely inside the console, better than putting it on the charge pad that would would allow the phone to go flying in an accident or a hard breaking situation. I think the charge pad on my 2016 Silverado is a poorly thought out addition and I would give it a fail.

It is the only thing I really do not like about my truck,

I have a Galaxy S8 and it's the same thing more or less. I can get it to connect provided I have no case on my phone( which is never) but it doesn't really seem to charge. I just use the Android auto and have the phone tethered to the truck's dash thus charging it and not needing the pad anyway.

I'm having the same issue in a 2017 Sierra Denali. My iPhone 8 won't charge with or without the case. I can't get it to connect at all with the rubber insert in place, but when I removed the rubber insert it will connect to my truck, but only for a few seconds and then it drops. I was using an iPhone 6 in a Bezalel case and it worked perfectly fine, but the iPhone 8 won't charge at all.

I use Apple Car Play all the time so it makes wireless charging irrelevant since the phone needs to be plugged in. IMO the wireless pad was a waste of time.

It's mossy likely the same issue people have with other phones.

 

It's just not sitting on the pad in the correct location to charge.

 

The charger is positioned poorly and is weak in these trucks.

Mine wouldn't work until I rotated the rubber mat 180° .. I have the note 8 now, but had the note 5 before this. Both work great, but I don't use cases for my phones

In this particular case with the iPhone 8, I really don't think the problem is the rubber mat or that the phone isn't sitting correctly on the mat. When I completely remove the mat and the phone is not in a case, I can easily place the phone pretty much anywhere on the charging tray and the little charging icon appears almost immediately on the touch screen (little green lightning bolt by the phone icon) and then goes away after 3 or 4 seconds. From what I've read on the internet, it appears the iPhone 8 needs a 2amp wireless charger to work properly. Found this from another internet forum regarding the GM Charging pad: "I tore the unit apart and found that it only provides about 1 amp of power which is not enough to power the new generation of wirelessly charging phones. As i understand it, if you have a phone that is capable of "fast charging, you need 2 amps to make this feature work..."

Fast charging has been in androids for years. My note 5 from two years ago worked, and so does my note 8. I wouldn't say that the new generation of wirelessly charging phones won't work. Maybe it's an iPhone thing, but the androids charge fine with the low power

I am experiencing the same thing on a 2016 Tahoe. Regardless of where I place the Iphone 8 it will not wireless charge. A friends Samsung works fine. A GM rep indicated it could be related to where Apple put the charging coil in the 8. Disappointing that GM and Apple didnt get this right. Probably didnt help that Apple was so late in wireless charging. Its part of the reason I waited on this Apple phone. At this point, Im not willing to take the rubber pad off until I hear more from GM.

Is there any way to upgrade the current wireless charger? I am having this same issue and I really think GM should remedy this issue.

razor2307, don't bother taking the rubber mat off, it doesn't fix the situation. I tried. Taking the rubber mat off allowed the truck to connect to the phone more easily for 3-4 seconds, but then it disconnects and never charges. I too would like to know if there is a way to upgrade the charging pad in the truck. I'm disappointed Apple and GM didn't get this to work.

Found this regarding the type of wireless charging iPhone 8 uses: "The new iPhone 8 and 8S phones use the older 1.1 Qi wireless charging standard developed under the Wireless Power Consortium (WPC); it supports 7.5W (5V/1.5A) wireless charging."

 

and found this from a GM Website:

 

"GM’s wireless charging feature supports both the Powermat and Qi wireless charging standards. Specifically, the system supports the following wireless charging specifications:

  • PMA 1.0 (Powermat)
  • WPC 1.0 (Qi)
  • WPC 1.1 (Qi)

By supporting the two major wireless charging systems, General Motors has ensured that its vehicles are future-proofed and does not lock customers into a single standard."

 

They appear to be compatible?????

I agree rtreptow7. My Tahoe owners manual indicates what you found that the wireless pad supports both PMA and Qi wireless charging. My Iphone 8 does nothing when I set it on it. I verified my vehicle pad works with a Samsung, I verified my Iphone 8 charges wirelessly at a pad at Best Buy. I have contacted both Chevy dealers here but havent heard back yet. It seems like a GM problem.

Chatted with the GMC Infotainment division this evening. They said that since the iPhone 8 just rolled out they haven't had a chance to test the phone. I was advised to check back in a couple of weeks to check the compatibility status. He said that not all phones are compatible with the wireless charging feature. I mentioned that the standards are shared between the iPhone 8 and the GMC, but he just sent me the link below, 3 times.

      I wonder as well, why they would send me a text message with links to these suggested procedures totalling over $10,000 without even the slightest hint of how they arrived at these being necessary.

      OCI, not when but why?

      By Grumpy Bear · Posted

      https://precisionlubrication.com/articles/oil-filter-efficiency/     For them it is a problem of $$$$ and compliance. To cover both they have to lie from the heart.    Government wants low waste oil numbers so the bar needs to be very low on contamination to met that requirement.  Consumer wants cheap maintenance (perceived cost). Again requiring a low bar.  OEM wants high margins at a cost effective warranty rate and lots of repeat customers. More low bar.  Filter manufacture wants the same thing the OEM wants. See the pattern?   Consumers are fickle and also want perfection requiring a HIGH bar. Inconsistent with all of the above. Consumers can be, when the put their minds to it, inquisitive, love winning arguments which requires some useful information to be available to support them. And this is where it gets sticky and the lies begin.    Information needs a solid well grounded point of reference if we are to compare in a useful way. There is a standard for this.  ISO 4548-12. This standard sets the particle size at a specific Beta ratio and darn few are faithful to its intent.    If they don't state the test method they change the particle size or the Beta ratio to hit a perceived favorable standard. They obscure the information in a way as to prevent direct comparisons leaving the consumer with one method. UOA's with an ISO 4406 test result. Pricey and not allot of labs willing to do the work. Lobby work happens everywhere, not just at the seat of government.

      IF,IF,IF. If they cared about quality instead of profit and this applies to any company, what a concept.

      2001 GMC Sierra - Banging feeling in steering wheel

      By Christopher Miller · Posted

      Good Morning Gents..hope everyone is enjoying a beautiful saturday morning. I have a 2001 GMC Sierra that I bought used in 2018. I am the 2nd owner and its a beautiful truck. Ive put about 60,000 miles on it and recently the front end has felt funny. Kind of loose when hitting bumps adn sometimes I actually feel a "bang" in the steering wheel. I took it to a local guy who said that everything was tight and he tightened the steering box. It didnt feel much better, so I had him replace the front shocks, which had noto been done since I bought it. It had the check enging light on so I took it into a local garage to fix that and check out the suspension. Everything is original and the rubber bushings that I can see look bad. They said everything was tight and there wasnt any play in the front end. Im concerned about the banging feeling in the wheel. Ive been driving this truck for 8 years, so I know how it usually feels and this is something new. Its a second vehicle, so I dont drive it all the time, but Im trying to use it more often. I live out in the country and some of the  roads are kind of rough and I alive on gravel roads. Anyone deal with anything like this before?
