3 Engine Cooling System problem of the 2000 Plymouth Neon

Failure Date: 03/31/2003

When attempting to have all NHTSA issued safety recalls completed on my vehicle service repair center manager. Stated they only applied to certain Neon's not all of the 2000's. I have yet as of this date been able to accomplish NHTSA recall id#99v043000, #99v114000 nor have I ever received the addendum referred to in NHTSA recall id #00v366000. In recognition of the recent problems experienced w/my vehicle, overheating, inoperable driver side window, horn & airbag system and my having also experienced brake problems, I feel these recalls are essential. However, they are going unrecognized by annapolis tate Dodge.

4 Engine Cooling System problem of the 1996 Plymouth Neon

Failure Date: 11/19/2001

My Neon has been intermittently stalling out when slowing for stops, starting the vehicle and intermittently when I am at idle. This becomes an issue when I am pulling off the highway and the car stalls, thus making it difficult for vehicles behind me to stop in time. No crashes have incurred yet, but they are possible. I have taken it in 3 times now to lebanon Chrysler-Plymouth for repair. 11-fuel pump and various cables replaced. Problem returned. !2-idle memory needed to be reset. 1-2-throttle body and thermostat need replaced. . . All of these items were completed on different dates for the same problem. My car is currently at lebanon Chrysler and hopefully the problem will be fixed completely this time, but it has been a safety issue while I drive. I leave sufficient distance between myself and other vehicles, but I cannot predict how others will drive. Thank you for your time and please let me know what you can do to help. Lisa brady.

5 Engine Cooling System problem of the 1996 Plymouth Neon

Failure Date: 10/23/2001

I bought this used car from a dealer. My fiancee started to notice that the engine temperature gauge was rising fast. She started to hear bubbling gurgling sounds from the cooling system. The car started to lose power. I phoned Chrysler to see if they could cover the expense since it was out of warranty and had prior owners. I ended up getting the car repaired and Chrysler only offered a 15% discount. They should have paid the whole bill of $1853. 03. There is such a thing as silent warranty that I have read about on the internet. I want them to reimburse me and I am going to file several written complaints.

6 Engine Cooling System problem of the 1997 Plymouth Neon

Failure Date: 06/08/2001

Blown head gasket. Oil in cooling system. Contacted Chrysler, no help there. I still owe $5000 on a car with a messed up motor. I believe Chrysler knew these gaskets were defective and did nothing about it. There was a TSB put out in 1998. Why weren't owners notified of the problem. It's alot cheaper to replace the head gasket rather than replace the motor. I called the 1-800 number and they don't want to talk to me. Same with the dealership I took it to.
