Happened many times before....Car won't start after sitting for a couple of hours..Usually it takes like an hour then it starts again and the problem goes away...Today the car was on for a couple of hours and I turned it off for a few and went to go start it again and nothing happened..The lights go on and everything so its not the battery..What could it be and how can I fix it?? the cars sitting in a parking lot and I want it to get outta there....

 

I had a exactly same problem.
The solution is to remove the starter and regrease it.
Search the forum and you'll see my post with lots of tips.
This is common problem with 4th gen Max and very easy to fix as well.

 

Where is the starter?? Can I do it myself without going to the mechanic...please help

 

relax man... it's easy to fix! If I can do it then you of course you can do it too!
One more thing... if you can't start you car then tap(lightly) the starter (under the intake) with a hammer and if you can start then you need to regrease the starter.
My car had exact same problem and after the regrease the starter works like new one...
Also, when I opened the starter oh man.... the grease was all dried out, too.
Here's the site that tells how to remove and regrease your starter!

Thanks I just banged it up and its working..for now as for tomorrow its time to regrease...

 

Glad to hear that Doodiemax.
When you try to remove the starter then you'll find two bolts holding the starter.
The bottom one is kinda hard to take it off.( about 5 inches long )
You'll need a break bar or something to turn the bolt.
When you regrease the starter make sure you use high-temp grease and don't put too much grease on it!
It's pretty stright forward job and it's good to know that you just saved couple hundred $$$.
Good luck to you man!
