Example complaints

“The NEON was driving down the road when I lost acceleration and it spewed transmission fluid (and mixed with what I later found out was cooling fluid) all over the road. The car could no longer accelerate and is inoperable. The mechanic later determined that the radiator had failed and leaked coolant into the transmission causing it to overheat and fail.”
NHTSA complaint #10442685, filed 2012-01, 134,000 miles“Idling of the motor was not regular. This 2004 Dodge NEON was purchased used ,and I had nothing but problems out of it. The check engine remained on, and the engine idled terribly. Very dangerous on driving, will cut out and proceeds to cut out most of the time. Also, when pushing on the accelerate it hesitated to the point that one day I may get run over and killed.”
NHTSA complaint #10190420, filed 2007-05, 47,000 miles“The transmission cooler that is internal to the radiator in my 2004 Dodge NEON started to leak causing transmission fluid to enter my cooling system and get into my engine. This is the 8th time I heard of this occurring in this model, this is winding up being an extensive repair due to this failure of this component. Chrysler does not think there is a problem with this.”
NHTSA complaint #10212177, filed 2007-12, 90,000 miles“I was driving my car one evening when it suddenly stopped accelerating. I pulled over as best as I could being on a hilly curving road in a thunderstorm. I was able to check the transmission fluid; there was no fluid on the stick. I called for a tow truck and a friend near by. We bought transmission fluid to see if that would help. We put almost 2 quarts of fluid in it and attempted to put it in gear. It didn't go into gear, just coasted backwards and saw fluid on the pavement. It was leaking from front, appeared to be hose related. …”
NHTSA complaint #10231601, filed 2008-06, 30,693 miles“It was a sudden part failure which caused immediate danger. I was driving 35 MPH down a road near my home and my car would not accelerate. I immediately pulled my car over to the side of the road and called my father for help. He noticed the engine coolant pouring out of it's container and my transmission fluid dangerously low. We refilled the transmission fluid, but it wouldn't stay, it was leaking somewhere. We called a tow truck to take us to the nearest repair shop. The tow truck guy immediately told us that he's seen this problem all the time with Dodge neons. …”
