Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2004 Dodge Neon Owner Comments

problem #12

Jan 042012


  • 134,526 miles


The contact owns a 2004 Dodge Neon. The contact stated that while driving, the transmission shifted in and out of drive. In addition, there was a transmission fluid spill. The vehicle was towed to a local mechanic who performed a diagnostic that located the failure at the radiator. The radiator was cracked and caused the fluid to contaminate the transmission. The vehicle was not repaired. The failure and the current mileage was 134,526.

  • 134,000 miles
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.

The radiator cracked which leaked coolant into the transmission and damaged transmission which ended up costing me over $2,000 to replace. The coolant line or whatever runs into the transmission so when the radiator line or whatever cracks it allows coolant to to mix with transmission fluid and damages the transmission.

Car was taken for oil change and tune-up @ 134,000 miles. Couple days later car started stalling intermittently. Would start in the am from sitting all night but when driven to work and parked for 5 1/2 hours car would not start w/O a jump. Mechanic did not read anything on diagnostics. Went to advanced auto who read battery was low. Replaced battery & car still stalled. Car no longer responded to jump and had it towed to mechanic. When mechanic received car was able to start car with no hesitation and drove for 30 minutes. Turned car off and let it sit for another 30 minutes and had no problem starting. Mechanic could not figure out what was wrong with vehicle. Stuck with a car that intermittently stalls and shows no other signs of failure. Car has not cut off while driving only stalls while trying to start vehicle.

S10 appropriate handling - letter from regarding Dodge problems. 2004 Dodge Neon. The consumers wife was driving the vehicle when the vehicle suddenly stopped accelerating. The transmission failed and she was barely able to make it to the side of the road. The hood was extremely too hot to touch and noises and liquids were coming from the vehicle. The consumer stated there was a known problem with the transmission cooler in the radiator. The transmission, radiator, hoses and thermostat had to be replaced. Also, the engine was flushed.

Check engine light came on and engine started more gears or shifting into drive.loss of transmission fluid and coolant. A piece of transmission line or fitting corroded and let loose inside the radiator. This caused the mixing of fluids into the transmission and cooling system.radiator failed and bled fluids. Radiator was replaced and coolant system was flushed. Transmission was also flushed.this very same problem occurred to my co-worker that has the same type vehicle(04 Dodge Neon,2.0 litre engine,74000 miles). I suspect it is happening to every customer that has that type and year Neon. Part not available.

The contact owns a 2004 Dodge Neon. The contact took her vehicle to the dealer to have the brake pads serviced. The technician discovered that the transmission solenoid pact was leaking and made the replacement. The repairs totaled $1,000, of which the contact paid $865. Two days after the repairs, the vehicle revved up while driving 25 mph. On one occasion, the contact released the accelerator pedal to slow down and the vehicle began accelerate on its own. She attempted to apply the brakes, but the vehicle still accelerated. When she arrived home, she noticed that the check engine indicator was illuminated. She took the vehicle back to the dealer, but has not yet received any feedback. The manufacturer has not been notified. The current and failure mileages were 96,978.

Neon 4-cyl

  • Automatic transmission
  • 90,000 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.

  • Manual transmission
  • 3,500 miles
I have a 2004 Dodge srt-4. I have had it since April 3rd 2004 and ever since about 3500 miles I have had a oil leak coming out of the cold side intercooler pipe. I have taken it to Dodge and they have told me that it was normal on my car. A brand new car with a oil leak, doesn't make any sense. I know its blow by coming out of the PCV system and a catch can would stop the oil from leaking. But what I don't understand is why didn't' Dodge put one in the first place? my car now has 45000 and it still has the oil leak and a big group of oil spots on my white driveway.

While driving 45 mph a loud ticking noise was heard coming from underneath the hood of the vehicle. Consumer drove the vehicle to the dealer for inspection, however the mechanic could not duplicate or resolve the problem. The headlights had gone out while the consumer was driving the vehicle, the wheel needed to be replaced, there was a problem with the brake line in the front, the wheel bearing was broken in half, the fog lights had gone out, there was a roaring sound when the vehicle was in motion, there was a whirling sound in the engine which would get worse when accelerated, the rotor/pads rusted, the steering pulled to the left, and when slowing down, the steering wheel would shake.
