I own a 2006 300c 5.7 hemi, I’ve owned this car for about a year last original owner was a 70year old who bought the car brand new off the lot in 2006 with that being said the cars in amazing condition the only complaint I had when buying it was that the navigation stick stopped working and a piece of the chrome was peeling back, everything else was immaculate, as of right now it just clicked over to 120,000 miles, I’ve replaced spark plugs, axle back exhaust cold air intake and a tune, last week the car starting throwing a code for losing communication to ecu pcm and it will need a new computer which I mean isn’t to big of a deal 4-500 dollars, but as of today it started also throwing a code for mds cylinder deactivation circuit stuck open which I’ll have to rip apart the intake manifold to access, all in all if your looking for a nice reliableish v8 luxury car and for the year I’d definitely recommend a 300c weather the 5.7 or the srt8, aslong as you keep up with general maintenance full synthetic oil every 3k miles, flush out your diff and transmission spark plugs and coil packs it will last you 200,000 plus miles.

July 2022 Presently I do own this car and it is 15 years old. It has done well for 15 years and 2 months. This past March I was told it needed a PCM but Mopar no longer had the part nor serviced PCMs. I ordered one from the Computer Exchange and had to return for a second one and my car is still not driving right. Like the consumer from Florida said replacing a part with a non mopar part, the car shuts down multiple times at anytime and starts again especially when I put gas in it. It has been a nightmare. I am trying to keep it for awhile and looking for that exceptional someone to repair the car. Both PCMS were put on the diagnostic and they said that they had lost communication with the other parts of the car.

Has a kill program that's dangerous. Say a non MOPAR part is put in... Car will start to shut down at anytime. It will restart but can happen anytime. Sometimes with no code. I learned on forums where owners talk of it. It's an awesome vehicle but comes with it's headaches you will learn with research. Any 300C forum or even 300C owners facebook page is a great research tool.
