Chrysler - Cruiser :: 2007 - Won't Start Easily After Maintenance - Gear Shift Button At The Top Of Lever Sticks?

I have a 2007 Touring Edition PT Chrysler Cruiser which was just a few days ago repaired because of damage under the front of the car. Front bumper, ouside and inside grills, all housings and connecdtions in the front area were replaced, including air conditioning mechanisms. Received car on Monday, Friday evening, it wouldn't start. Just made a tet tet tet or clicky kind of noise, no turning over of engine, then there was no noise ... just wouldn't start. Got jump, still wouldn't start until the third cycle that peddle was pressed. Now I'm finding that the longer I let the car idle, the more likely it will be to start after more than two hours of non-use. Had all electrical circuitry checked ... battery's 100 percent, alternator is working fine, but it's still not starting.

Car's gear shift button at top of lever is also sticking when I put it in park to turn the car off. Have to pull the top button up to get the key out. This was happening before car was repaired underneath front. Talked to warranty person, and he felt that maybe the ignition starter switch (if that's what's wrong) and sticking gear shift may have something to do with each other. Since car is actually starting after being run, maybe it's not the starter switch. I'd hate to get it repaired if that's not what it is. Thinking about having a Chrysler dealership do a diagnostic test on it to pinpoint exactly what is going on.

What's happening? Why is my car cutting not starting in selective situations after not having been idled for a couple hours or more?
