No warnings or other issues. After looking the problem up on the internet, seems to be a very common problem with this car make and model. The lights turn on yet it will not turn over. I am attaching photographs of the damage to the cylinder head at cylinder number 2 and also the fragments that I was able to remove from the intake manifold which appear to be parts of the valve seat from the exhaust valve at cylinder number 2. . The vehicle was taken to an independent mechanic and repaired. Then came the white cloud of smoke out the exhaust death for a car.
My husband and I are in our seventies so we aren't reckless with our vehicles. There were no warning signs of any engine trouble and the service writer couldn't believe what had happened with only 44,612 miles on a 2007 vehicle which we bought new in 2007. I was able to get some of them out and they appear to be parts of the valve seat from cylinder 2. We carry an extensive inventory of used, overstock and surplus engines for all 2007 Chrysler 300 applications including gasoline and diesel engines. Mechanic reports that there are bent valves and 4 of the cylinders are misfiring.
I have also had trouble with this car several times just shutting down or almost shutting off jerks like you are hit and seems like it is shutting down but then returns to normal while sitting at a light or a stop sign. The manufacturer was notified of the failure and stated that the vehicle was not included in the manufacturer recall related to the failure. Thought I was hit from behind however there was no car behind me. This has happened on numerous occasions. While driving 45 mph, the vehicle stalled without warning. Mechanic assessment: Need a complete new engine. The manufacturer was not made aware of the failure.
Within 3 min of failure as I set at a traffic light the cooling temp light came on. We pulled the head and found that cylinder two had damage on the head and corresponding locations on the piston. No warning lights went on, no dash lights went on, car was not overheating. My research shows this an ongoing issue with Chrysler hemi engines. Monday as I parked the car, I noticed white smoke coming out from underneath the hood.
We have always had our car service by dealer when we needed oil change, tune up or whatever was necessary for car. We like our car which is why I went through the trouble of rebuilding the engine 2 years ago and have gone to the lengths that I have gone to this time. The approximate failure mileage was 52,000. I'm obsessed with this car I'm not joking. It eventually stopped but the car kept running rough and smoking. I have taken such good car of this car from day 1! After the vehicle was taken to a dealer for routine maintenance, it began emitting smoke.
About ten minutes later it was started, backfired and failed to idle. The car had recently been driven and parked in a garage. The vehicle has had numerous times when it de-accelerates while turning to the right. Regularly maintained vehicle with all necessarily regularly scheduled maintenance in addition to things that popped up and shouldn't have gone out. The Pistons were crashing into the heads? Chrysler should pay for our problem since they knew there were problems with 300, 300C engines.
Each time the vehicle has been checked out I have been told that no problem registers and cannot be diagnosed unless they mechanic can get it to duplicate. The vehicle does not show any error codes, nor does it have any stored codes from the occasions that this particular issue has come up. So this means if this problem should happen again I would have only put 15,000 miles on my car in three years. Went into the store for approx. We keep car in garage and drive at posted speed and always keep our vehicle in new condition. I'm hoping there is something you can do for us to right this situation.
After work I started the car and could not shift the gear out of park. We have been loyal Chrysler consumers for quite some time as well as was my father before me. The mechanic had to replace timing belt and water pump just to get it running enough to run the codes. My next step is to contact my congressman and senator. They do not stand behind their product! The engine is a complete loss.
