With the higher temperatures this weekend, my K4 all of the sudden wouldn't respond to fob commands, app commands, and even after I manually unlocked and entered the car I could still not start the car. Even pressing the start button with the fob.

Once the temperatures cooled down, all of the sudden the fobs and car worked again.

Now I replaced the batteries on the fobs, I went to O'Reilly's and check batteries and alternator which they said are fine.

What could be the issue? Today the car shut off on me and didn't start again, I had to get it towed to the dealership but they have no availability to fix it soon or replacement cars.

I don't know what to do 🙃 anyone has dealt with these issues?
