2017 Porsche 911 Carrera S — need advice: USB ports and wireless charging both quit

NorthNomad4Community StarterMar 2, 20262017 Porsche 911 Carrera SBoston / New England

2017 Porsche 911 Carrera S, about 8,200 miles. Phone charging stopped on both the wireless pad and USB ports, but everything else in the cabin seems normal. Before I pull trim apart, are these usually on one fuse/module or separate circuits? I'd rather test this logically than start replacing parts.

Ask what changed right before it started. Two 2017 Porsche 911s can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. This is from a 2017 Porsche 911 in Boston / New England with 8,200 miles. Run the total, not the monthly, before you commit. Video is ugly but it shows the hesitation.

Quick add on that: If a shop can't duplicate it on the 2017 Porsche 911, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. Just my two cents from doing this recently. Not driving it hard until I know more.

Intermittent stuff lies if you only catch it once. Get a real battery/charging test on the 2017 Porsche 911, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. On “need advice: usb ports and wireless charging,” that was the fork that mattered for me. Run the total, not the monthly, before you commit. Wrote this up on my lunch break.

I wouldn't throw parts yet. A pressure test beats staring at a dry driveway if the 2017 Porsche 911 is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. Run the total, not the monthly, before you commit. I'd rather pay for diagnosis than a second guess-repair.

2017 Porsche 911 — surface rust underneath a winter daily

There is early surface rust on brackets, fasteners and seams underneath, but nothing structural. For a salt-belt car, what treatment slows it down without creating a hard coating that traps moisture?
