I bought my 2006 Chrysler 300c brand new & I've been the only owner. It was purchased straight from daimler/Chrysler, ordered & built to my selected specifications through Chrysler. I set the order in February 2005, it was built & finished 11 Nov 2005. This was done while I was finalizing my career in active duty military service & retired. I returned to the u. S. 7 Jan 2006 & that's when I saw & picked my then brand new 300c. I fell in love with that car ever since. I truly love this car & to this day still love this car. I've never had any major issues with this car from day one otherthan putting gas in it, very dependable car. In 2007 June I was diagnosed cancer of the bone & blood (multiple myeloma, stage 4). After being hospitalized for apprx. 18 mths, one day while coming from chemo it started to over heat & blowing steam, had it towed to nearest dealer & had to have the fans & the sensors replaced, 1st major problem, then after that it was the shift lever stuck in park, then the "a" frame & control arms, now in Nov 2012, after attending my grandmother's funeral, I filled it up @ a gas station & it shut off, would start back up but continued to shut off. There was no check engine light then once I got it started it would sputter, kick, & stall, this was repeated for several miles down the hwy & was fine til I had to fill it up again from then on it continued to do so every fill up. I did receive an indication of the gas cap (replaced) then June 2013 I filled it up as usual & it shut off & it was difficult to restart, I waited & start it again it did so I pulled on to the road, it began to stall, sputter, & buck, as I crept home, I heard a loud crackling sound lost all power, had it towed was told #4 vlv had fell down in the cylinder, after 3 months 2008 5. 7l engine put in, problem still exist, evap solenoid, canister, pump, & filter assembly replaced.
