The engine on the 2005 Dodge Magnum 3. 5l has a problem that could result in a serious injury or worse. In this case and citing a TSB from Dodge that there is an issue with the rocker arms, valves, and egr valve that allows this engine to make a lot of noise. I contacted Dodge directly and they are unwilling to help out. I think someone from your dept should look into this problem it does not only affect the Magnum but any Dodge vehicle with this motor.
Bought an 05 hemi awd Magnum w/20,000 miles in 07. Warranty expired at 85,000miles. Problems after problems, rack and pinion fixed, egr valve fixed, torque converter replaced once and still having the same issue. Shudders, vibrations, hard engine noises and stalls, pulls to the right, electrical problems with windows, sunroof, seats, gps, instrument cluster, power outlets, hood and hatchback just fall down and bump your head. Passenger seat was missing bolts and wasn't fastened to frame. $200 keyless entry key replacement. No where near 24 mpg more like 14 down a flat 55mph highway. Currently 114,000 miles oil always changed around 3,000 miles and had a 3 tranny flushes. Take it to certified Dodge dealerships and they cant figure out what is wrong with any of those problems and try and tell me that's the way it is. Uhhhhhhhuh. . . . . Lemon?.
