Hello MHix1,
First, we'll want to confirm the wireless charger in your car is Qi-certified. This is a compatibility requirement for functionality. You can check the car's owner manual for this information or contact the manufacturer.
If you've already checked this, then the following details can help us determine next steps, and isolate the behavior.
- Are you able to charge the iPhone 14 Pro Max using a Lightning cable?
- Have you tired removing any other accessories attached to the device, including a case? How to wirelessly charge your iPhone has some information on how some cases may interfere with wireless charging.
"Wireless charging uses magnetic induction to charge your iPhone. Don't place anything between your iPhone and the charger. Magnetic mounts, magnetic cases, or other objects between your iPhone and the charger might reduce performance or damage magnetic strips or RFID chips like those found in some credit cards, security badges, passports, and key fobs. If your case holds any of these sensitive items, remove them before charging or make sure that they aren’t between the back of your iPhone and the charger."
We look forward to hearing back from you.
Regards.
