I have a 2005 Dodge Magnum with a hemi and i have been experiencing a jerking problem between 25-30mph. It also does it at highway speeds. If you sit in your chair and rock back and forth thats what it feels like. I have had it a two dealerships and they tell me nothings wrong. One of the service guys said to take it out of overdrive at low speeds. Come on..And of course everytime I take one of the service guys with me it doesnt do it. I already have had all the updates, flashes and computer updates.
I also had the same problem with the left rear window not going down. They changed the regulator and it seems to work fine now.
I have to get this problem figured out before the warranty runs out,,,So please help

 

You might be feeling the MDS kicking on and off. Mine does it also, but I'm getting used to it.
