Vehicle was taken to the dealership and verified that the component has failed and that Chrylser has known of this issue for sometime. 2. I have replaced the bad blend door actuators multiple times on each side of the dashboard, due to the unbearable clicking noise within the dashboard and not letting the ventilation systems change directions in the vehicle.

Alternator caught on fire while engine was stopped\car parked while driving on interstate, the battery indicator came on, indicating a problem with the charging system. I continued on to my destination about 3 miles. When I turned the car off, there was an obvious smell of something being "hot" and I raised the hood to see if I could see it. The alternator was obviously very hot, and slightly smoking. Assuming it was OK now that I had turned it off, I went inside the building to call the dealer. Luckily, I changed my mind about trying to drive the car any further and decided to have the car towed and went outside to wait for the tow truck. When I got back to the car, the alternator had actually caught on fire and was blazing, dropping some melted materials onto a underbody air dam and appeared to be spreading. I was able to extinguish the fire before any more damage occurred. …
Car began to loose power under pressure, engine light would flash. Usually when cold or pulling hard on a hill or passing. Engine ran rough, misfiring and out of balance. Could not continue to pass on one occassion; had to pull back, wrangle out of traffic and stop vehicle. Misdiagnosed: replaced plugs, coil & injector on valve #5. Did not correct. Finally diagnosed as bad camshaft. Vehicle has a Hemi. Technician stated he has replaced many of these on various engines with a Hemi in a four year range. Stated it is a common failure on those vehicles but not listed on a recall. This failure is a safety hazard. Having expectations of the vehicle to accelerate quickly, as it normally would, nearly caused me to get into an accident. Additionally bogged down traffic as the vehicle would not continue at a speed over 45 MPH. …

I was on interstate 40 when I noticed a whining noise coming from my vehicle just as I took my exit. I was able to make it to my destination when I noticed a burning smell coming from under the hood. I went to the nearest gas station and soon as I pulled in my vehicle began shutting down. The message said it could not detect my key and it was going into battery saving mode. Shortly after that, all power was lost and I was unable to restart the vehicle, I was unable to roll up my windows and lock my doors. It was after midnight when this occurred and the gas station was closed I had to enlist help from strangers to try and figure out the problem to no avail. I ended up staying at a hotel overnight and the next morning I was able to get a jump and get to the nearest auto parts store where they tested the battery and determined the alternator was failing. …
