2013 Challenger R/T. Push start. The problem first started out to be when I would push start button the car would just keep cranking and not firing. It does not do it all the the time maybe once or twice a month. Now sometimes I push start button and only cranks a couple times but does not fire. I also noticed the car is idling at about 550 rpms. I thought it was the battery possibly but had it tested and it is in good condition. Any thoughts?

Have you taken it to the dealer, it should be under warranty unless you are over 36,000 miles.

There could be a multiple of problems causing this. Your idle should be 700 - 750 so a lower idle could be a vacuum leak somewhere. Failing to start could be a failing crank sensor. You should have the dealer run a diagnostic because hit and miss problems are hard to catch.

Same issue if you pull out the push button and use the Fobik ?

Car has 30, 500 miles. I took the push start out and used the fob and the idle seems to have gone up to 700 and the starting issue is random so no trouble there. What is the issue with the push start and idle being associated? And will this solve starting trouble. I may take into dealer before warranty is up.

The car will idle at 500 or so if you do not have load on the alternator. It kicks up to 700 when the AC compressor, cooling fans or other load kicks in.

This may help. I have a Durango with the 5.7 Hemi and it's the same engine that is in my Challenger R/T and not the truck 5.7. I had the same issue starting the Durango, but the problem got to the point where I would push the start button and it would crank and not start. Once I got it started, it would be no problem starting it the rest of the day. It happened when it was cool to cold out side and the gas mileage and performance went down. Even thought it was the battery and changed it to be sure and it was not the problem. Took it to the dealer and it was the fuel pump module relay.
