Can u put AC stop leak in your car

Not a good idea, that stuff can clog up the system and rarely fixes anything at all. If you have a 2017 Impala I would definitely not mess around. If the car is under warranty just bring it in. If not you will need to find a good shop and it's super rare for an evaporator core to leak after 1 year.

I Agree with the expert AskAlex! Stop leak is bad news for the compressor even if your warranty is lapsed replacing a hose is much cheaper than a hose now and a compressor a few months from now from malfunctioning from stop leak. Make sure the technician checks the valve core in the ac line high and low side both. If you use stop leak make sure you tell the technician when you have it repaired!
