Did you check or change the battery in the key Fob? Low battery can cause it as it happened on our Murano. Wife had the fob in her bag and I guess it was pressed against something while it was in the - drained the battery.
Glad if I can help.Thanks for your response, RedFox. I'm now trying with the 2nd keyfob and see if that's better. I've only had the car for a few weeks, so I didn't think it would be the battery. I sure hope you're right. Thanks.
