I took it in after the first time it did the "Shift to Park" warning, but it was already past the warranty and they only replaced my key fob...not even the issue but cost me $75. They couldn't replicate the "Shift to Park" so they said they couldn't do anything about it if they can't replicate it. That was about 2 years ago. I am almost at 100,000 miles. My battery voltage is running between 12v to 14v, so my husband doesn't think it's the battery, but willing to have it checked. I have to wonder if it has anything to do with a recent oil change I had. It started running rough after that, so I wonder if something got pinched during that. Thank you for the feedback. I will keep looking into the issue.@MalibuOwner2016 those oddities suggest to me two problems. The shifter I bet is a separate issue and is the same issue everyone in this thread has experienced. It seems yours is quite intermittent and you have been accepting it. Personally I would have had it replaced under warranty but if it doesn't bother you that is a personal decision. With the other symptoms... difficulty starting, random warning lights (no codes I assume?), and reset radio stations would make me wonder about the battery. Other causes are possible such as a pinched harness, loose connector, bcm or ecm... etc but battery would be my first guess.
