Two problems related to vehicle shudder have been reported for the 2006 Chrysler 300C. The most recently reported issues are listed below.
I was driving one day my Chrysler 300 c 5. 7 hemi shut off in the middle of the freeway I pulled over to the side of the road car coasted cause everything shut off I put it in park tried to restart car wouldn't start did it a few times car started and died idled rough felt like I was running outa gas would stay at the right roma keep stalling out so I gave it gas and car stopped shaking and ran fine a month later did the same thing this time check engine light came on and said random multi misfire all cylinders I spent 1800 replacing the coil packs plugs and still didn't fix it turns out the valve seat dropped and chewed one piston up all too heck needs a new motor only had the car for $ months has 112,000 miles on it don't have the money for new motor cars just sitting with head off and valve seat is gone.
My 2006 Chrysler 300c was a car that was well taken care of. It had less than 90,000 miles at the date of the incident. I was in a drive-thru and I turned off the car to save fuel. When I went to restart the vehicle, the car made a loud grinding noise that sound similar to sticking a baseball card in bicycle spokes but much louder and stronger. I had the car towed to chuck clancy Chrysler and I was informed that a valve seat had dropped and destroyed several cylinders. The bill was $3,000. This car was always maintained by maintenance records and the oil changed with pennzoil platinum ultra. To add to this story, I received the car back and the same issue happened again two weeks later. Needless to say, I was out another $4000 for this repair. Chrysler refused to cover it and gave me the cold shoulder. I would never purchase a Chrysler product again.
