Purchased this car few months ago. Monday feb. 24th, 2020 I was sitting inside my car when suddenly I notice a fire in the engine. I immediately grab my wallet and phone exited the car and called 911. The firemen came (fire was out by that time) . I had car towed to dealership (4460 mchenry ave, modesto ca 95356 central valley Chrysler, Nissan) they had car for couple of days and today called me in to tell me that a rod shot through the oil pan (I assume it occurred after fire started because I did not hear anything prior to fire and was not driving car when fire started). They tole me that it needs a new engine but they need to do more research on car and go into engine (which I guess is a big task). …
The vehicle has had two owners in the same family and has very low mileage (66000). The issue began in October of 2018. While driving on city streets at 40 MPH the indicators on the dash began flickering and making noise. This continued intermittently for three months but could not be replicated at an independent mechanic. Then in January of 2019 while driving on the freeway at 65 MPH the same issue happened except this time there the speedometer went to 0 but the car could still be operated. The car was taken into an independent mechanic who attempted to diagnose the issue for over a month but had no luck. As instructed by the mechanic the car was brought to the dealership where it was purchased brand new in 2006. The dealership kept the car for 6 days in February of 2019 and could not diagnose the issue, charging the owner a $240 fee for nothing. …
Drove my car to work in the morning with no problems. After work I started the car and could not shift the gear out of park. I tried several times, turning the car off and on etc. But it would not move. Called the repair shop. They came and removed the shifter assembly to get it to the shop and said they had to replace the entire shift assembly because a small plastic piece was broken inside and they couldn't just replace the piece, it had to be the entire assembly for the cost of $300.00. 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. 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. …
While driving the vehicle, making a right-hand turn the vehicle stopped running, with no warnings on the dashboard. It just shut off. While attempting to pull out of the garage one morning the vehicle lost steering to the right side of the car. The car was taken to a reputable mechanic who kept it for two days and could not find anything wrong with the it. The vehicle has had numerous times when it de-accelerates while turning to the right. On a couple of occasions the car actually stopped. 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. Now, the car will not turn over. It drove fine, I got home parked it in the garage and was getting ready to leave again, got into the vehicle to start it up and it will not start. No messages on the dashboard. …
On multiple occasions (more notably in moist weather, I.e. Rain, morning dew, and humidity) my vehicle has stalled out causing me to have to pull off or veer on to the shoulder of the road. 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. The dealerships in my area claim that they have never heard of this issue before and cannot attribute it to anything in particular. They are reluctant to provide me any type of advice because they don't want to be "subject to lemon laws" and so for that fact I feel that Chrysler is attempting to turn a blind eye to a very real, very dangerous issue with their vehicles.
Came out of the store to start the car. It wouldn't start. Engine made a coins shaking in can noise. Had towed to a service center, they asked if it had overheated, I said no because it hadn't shown any signs it had. They said it got so hot things melted and valve seats and pistons were ruined. I've read about Dodge Jeep and Chrysler Hemi 5.7s and valve seats and many people had this exact same problem with no sure reason as to why. I believe there is some defect in the engine itself causing this and extended warranty's won't cover claiming because valve seats aren't an internally lubricated part or some bs reason. Needs immediately looked into I'm about to lose my car over it!
Tl* the contact owns a 2007 Chrysler 300c. While driving 15 MPH, an abnormal noise emitted from the front of the vehicle.

The vehicle was taken to an independent mechanic and repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 52,000.
At around 106K, a valve seat broke and dropped into a cylinder chamber, damaging the cylinder. The engine is a complete loss. No compression in one cylinder and 50 lbs difference in compression in remaining seven cylinders. The car had recently been driven and parked in a garage. About ten minutes later it was started, backfired and failed to idle. A scope detected at least one cylinder was damaged. Mechanic assessment: need a complete new engine.
