Well I have had my Magnum for 37,000 miles and listed below are the problems I have tracked. The car only left my stranded once.

-Pulls to the right
-Rear Diff leaking eventually locked up
-Leather seats cracking
-A/C works on and off so does the heat
-Will not go into gear have to re-start car (about 1 once a month hot or cold)
-Passenger airbag sensor went bad
-Parking brake cable rusted and had to have car towed.
- Front rotors are warped
-O-Ring on trans dipstick missing
-Tires near bald after 22k
-Driver floor mat hole worn through by gas pedal
-Drivers window very slow to go up or down
-Just today car would not get up to regular engine temp after a 1 hour trip. Only a quater of they way on the gauge I think the thermstate is stuck open.
-Somtimes in the morning car vibrates..feels like only running on a couple cylinders have to re-start.

 

One more to add I feel hard spots when making sharp turns during slow manuvering. Not sure if this is an electronic problem or not.

 

I have now had my 2005 Magnum R/T since November 2004. We ordered it in August of that year. The significant problems to date (110,000 miles) are one failed electric cooling fan - the plastic fan broke, locked up, and fried the fan motor; front anti-sway bar bushings; outer tie rod ends; the finish on the aluminum wheels was deteriorating noticably in nine months and Chrysler refused to do anything about it; the piece-of-junk Siemans radio has failed twice @ $400+ each time. And it has been the same issue - it will not eject the CD. The radio is currently unreliable, but I am not spending another $400 to fix a design problem. Chrysler owes me a radio. Other then that, the car has been bulletproof. Would I (knowing what I know now) buy it again? Yes! I would have ordered different wheels though. The fuel economy is fantastic, it handles great, I love the style, and we did buy a second Magnum R/T (a 2008) it was even better. Why Chrysler stopped making the Magnum is beyond my ability to comprehend. We would have purchased a third R/T Magnum if they were still built.
