I had a 2003 300M and loved it. Also have 2001 300M, my sister bought from me and then gave it back, reasons unrelated to the car itself. But the 2003 ran great, except for one issue with the transmission solenoid (sp)? Apparently, it stopped telling the transmission when to shift and it would therefore stay revved up way too high and shift too late and cause a huge thud sound. Once, I was hitting the brakes and it downshifted late, and the front end hit the ground. Turning it off and on is the only thing that made it reset itself for awhile. I had the solenoid replaced and it cost about $700 total.

Now, I got rid of that car and am driving the 2001 300M, which is overheating regularly all of the sudden. Added antifreeze and it was fine for a day. Then the same thing again. I think it is a thermostat problem, but can't really afford the repair and can't locate it to do it myself. Anyone know where it is? And is this something a woman can do alone? I did it once when I had a Geo prizm, but it had lots of room to work and took 5 minutes.

Hey, to all the people having trouble with the 99 300m not shifting right, my car was doing the same thing and I took it to the transmission shop, and they said they were sure it was the transmission, and that it would cost me $1,200 to fix, but a friend of mine told me to try changing the input and output sensors and I did, and ever since my car has been running good, and the price of the sensors was $60.00 for both. That sure beats giving the transmission shop 1,200.

My 300m has heat when I'm driving in town but when I drive on the interstate I lose all heat. I thank it might be the thermostat. dose anyone know where it might be?.

I bought a 1999 300M about 3 years ago at a great price. Two days later the car died but was able to start and run after sitting for a few minutes. I took it to a Chrysler repair center. They said that it was probably the fuel pump but they had no way of verifying it without changing the pump. I had them change it and three years later, it still runs perfect.

I own a 99 300m and I can't figure out why my battery light comes on after about 20 minutes of driving. The battery is new and the alternator is fine. What could be the reason for this I wonder?

I have a 99 300M that is becoming progressively harder to start. Usually moving the shift lever back and forth will solve the problem, but now it is taking as long as 10 minutes to start. Any ideas on how to fix?

My 1999 Plymouth Breeze (~160,000 miles) acts as though it is going to stall and sometimes backfires when accelerating. The check engine light comes on. When looking under the hood with the engine running, it did not appear that either of the front fans by the radiator were moving. Any ideas what may be causing this - fan clutch, fuel pump, input/output sensors???

I have been having the stalling and not starting problems since I bought the car brand new in 1999.

It first happened when the car was only 6 months old. I was driving about 40 mph when all of a sudden all the dash lights started to flicker and I lost power for about 5 seconds. Then they came back on and the car was running again.

Took it to Chrysler dealer, and of course they found nothing. After that I have continued to have problems with the car not starting. You never know when it is going to do it. You go start it and all the dash lights flicker and make that hissing noise, and the car will not start. I bought a personal jumper that I keep in the car just for this purpose.

Every time I took it to Chrysler, they could find nothing. They tried to blame it on a remote starter I bought, but I did not get that till I had the car for 3 years, and this problem started in year 1.

It did it again the other day and when I went to jump it. I got nothing, not even a spark when I hooked the cables up. I got lucky that I was a block from home, so I walked home. I went back 2 hours later and the car started like nothing had happened.

I have had enough of this piece of junk. Since 1999 I have had about 6 or 7 batteries in this car, a new starter, a new alternator. Numerous shorts fixed to try and solve problem. I have been told they have found loose battery cables on more than 1 occasion, and even had new cables put in, and the car STILL does it.

I have been told that it may need another ground from the battery, that the remote starter was the problem and many other things, but nothing has worked.

A buddy at work said to disable the security system to see if that is the problem. Anybody out there have it as bad as this? (Total times the car has not started is in the 30's)

Stalling and Dying 1999 Chrysler 300M.

Have the Input Speed Sensor and the Output Speed Sensor replaced. These parts have connections to the Transmission.

It is a cheap part with a low labor cost.

The Transmission no longer senses that the car is running and saves itself by limping home. Or, the car stalls and shuts down trying to save itself from damage. If the speed sensor fails the car assumes it should shut the engine off.

Yes the speed sensor is a problem when your transmission will not shift out of second gear. Another little known fact is when you have intermittent problem with the motor dying or not starting. (meaning turning over and not firing) There is a connector below the rear seat on the passenger side. This is a wire harness that leads to the fuel pump. The problem is the ground tab inside the connector or plug gets corroded and needs to be cleaned or replaced. I cut the ground wire from each end of the connector and soldered them together. I have not had a problem since.

This car has 190,000 miles and I have never had to do anything to it other than brakes, a couple of wheel bearing, and two speed sensors and inner tie rod bushings. Oh yes, and tires and oil of course.

I have a 99 300M 140,000and have had my car die/stall twice. This last time yesterday the car stalled-started right back up and made it to work. Leaving work before I got out of the lot, the car sort of jerked, not too bad, but I noticed it, then the check engine light came on. Made it home, the RPM's and the slight jerking continued. I will try some of these fixes myself to see if that helps.

Other issues I have encountered:

At night the interior lights all of them will blink on and off several times?

It has done this on three different occasions-I have had the car 5 years-so not too bad.

Set of brakes

2 sets of tires

Rear window won't roll down

Passenger side heated seat works sometimes - but I don't care about that-mine works!!

Have had a squeaking noise when the motor is running for about a year now - not sure if a belt is loose?

I will report back with results - wish me luck.
