Thanks for the quick response! Is there a reason why you keep it inside the car?

Unlocked the car normally and when trying to turn it on, received an error that there was a push button start malfunction. Tried both key fobs. Tried everything the dealer service suggested. No luck. I wasn't even able to lock/unlock the door or trunk. Service suggested I have it towed to them but it was late in the evening and I'm hardheaded and thought I could figure it out.

Searched online and decided to try jumping the battery. Worked. Drove the car around and turned it off. Wouldn't turn on again. Tried a few more times and had luck. It turned on but got an error that there was a critical charging failure.

Decided to take it to Advance Auto for a new battery.

Works perfectly so far. Still plan on taking it to the mechanic for a checkup but figured this might help someone with the same issue.

Thank you to everyone in this thread who had advice.

Press the power button twice without pressing the brakes

Put the car on N

Then press the brake and press the power button

In some cases you may notice movement in gearbox

Although the spar on N mode does not be afraid.

After you start the car you may notice that the warning message is gone

Tell me what happens with you after trying this solution.
