why is my MacBook getting hot when charging

Hi bgomez141,

We've got some tips to help keep your device cool and avoid any potential damage. First, we recommend checking your charging cable and power adapter. Using non-Apple products or damaged cords can cause your device to heat up. Also, charging your device in a hot environment can impact its temperature.

If you're still experiencing heat issues, try restarting your device or Reset the SMC of your Mac - Apple Support. If all else fails, you can schedule a service appointment with Apple or an authorized service provider.

By following these simple steps, you can help keep your device cool and avoid any unnecessary overheating issues. Check out the article: Keep your Mac laptop within acceptable operating temperatures - Apple Support for more detailed information, and let's get your device running smoothly again.

Take it easy out there!

Something is not right with what you describe. The MacBook Pro (16-inch, 2019) was discontinued about a year and a half ago, so it cannot possibly be "brand new". If it has only 4 battery cycles, perhaps it was serviced incorrectly. The fact it is "burning hot" means you should not use it. Shut it down. Do not use it. It's dangerous.

That is all the more justification to return it to the place of purchase as srome wrote. I recommend that you ask for your money back.

Hi,

My MacBook Pro is not that hot when charing the battery, charger is hot, though.

Charging finished at 100%, both, MacBook Pro and charger would be normal temperature.

If your new MacBook is getting as hot as you say it is and runs out of battery quickly i'd be taking it back to where you purchased it from to have it checked out or preferably replaced.
