Seven problems related to engine and engine cooling have been reported for the 2007 Chrysler 300C. The most recently reported issues are listed below.
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). They tell me that if they determine that they must replace engine at their cost (upon buying car dealership told me I could only get financed for car if I purchased a 24 month warranty which I did). They then advise me that this job of just looking into engine is $4,200. 00 and that I must pay them this amount prior to them doing their exploratory work on engine. They tell me that if I did nothing to cause fire (that is crazy to think I somehow in very short time as owner caused car to just catch fire out of the blue while sitting in it parked) that they will replace the engine with a used one. I feel as though a used engine may force me to go through this again and I was fortunate as if fire were to travel through gas line I would be dead right now. I believe they want to force me to pay this money up front and then try and tell me it is my responsibility to pay for everything, nullifying my warranty just so they do not have to honor their legal obligations.
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!.
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.
My car's 96,000 mile engine suddenly blew a #6 cylinder soon after I drove from work. I have an excellent service history. Never had any warning or issues. Now I'm told to pay 6500 for another engine with more miles. My research shows this an ongoing issue with Chrysler hemi engines. My next step is to contact my congressman and senator. Why has Chrysler been held accountable?.
12/5/2015 went to the market, 2 miles from home. Went into the store for approx. 15 minutes. When I returned to car to start is wouldn't start, not a battery problem. Couldn't move car so had it towed to dealership, mcpeeks Dodge of anaheim. Service writer told us that the noise in the engine was two valve seats dropped into the engine causing cylinder head and bore damage. We have always had our car service by dealer when we needed oil change, tune up or whatever was necessary for car. We keep car in garage and drive at posted speed and always keep our vehicle in new condition. 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. We had to pay $8749. 65 for a new engine which is only guaranteed for 3 yrs or 70,000 miles. We only drive about 5,000 miles a year. So this means if this problem should happen again I would have only put 15,000 miles on my car in three years. This is totally wrong. After reviewing associated problems on the internet I find that Chrysler has engine problems with 2006, 2007 vehicles. . . Engine goes out at around 70,000 miles, ours at 44,612. We paid $42,000 for the car new in 2007. Chrysler should pay for our problem since they knew there were problems with 300, 300c engines. We are out the towing to the dealership and the repair using a small savings we have as a retired couple. A seven year old car with 44,000 miles should have a engine last longer. As noted the car was stopped and parked at a supermarket for no more than 15 minutes and did not demonstrate any engine problems prior to this problem drove beautifully. We have the bill, which has been paid by us. I'm not sure how to download, but I could fax if contacted.
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. Usually it will start back up quickly but it is very dangerous in traffic and I have almost been rear ended 2 times because of it. I took it to the dealership 2 different times complaining about this issue, but they said they couldn't find anything wrong and that the computer system didn't show any problems.
I heard a warning like a tire blow out. Then I saw smoke from driver's side. . Nothing came on the dashboard. There was no warning on the dashboard at all.
