All-

Ever since I've purchased the 2011 Durango I've noticed when I'm driving at the speeds between 50-60 mph that I experience vibration from the engine.. After I top 60mph the vibration goes away... it's more like a sputter type of feeling. Has anyone experienced this with their Durango's?

Thanks,

John

 

Occasionally I've felt mine sputter when I lift the gas (maybe going into ECO mode?), but it doesn't particularly feel like a big problem.

 

Just spoke with the Service Manager from my local Dodge Dealership. Apparently this vibration as he calls it is a characteristic. Basically if you have the Hemi what it's doing is dropping down to "lean mode" as he calls it where gas is dropped lower into the engine forcing it to run in a economic fuel mode.. so you're not burning as much gas. When it goes into this mode you start experiencing the vibrations or what it feels like pistons suttlely missing. I'm sure someone on here can explain it a lot better than I have. From talking with the guy there is a certain way you can drive the truck to avoid it happening. I'm taking it in tomorrow to see what this guy says about driving it differently.

I'll update when I get back from road test.

 

So Multiple Displacement System (MDS) is kicking in at that point it sounds like.

Do you get the same thing with all octane levels?

 

I've only used 87 so far since I've had the vehicle. The sales guy told me that was suffcient. Do I have a d-bag with misinformation on my hands here?

 

Most probably fine, just wondered if it went away on another octane rate, or else another brand.

Sometimes different brands, especially in the States use different amounts of ethanol, and given that the engine needs to determine this to regulate the timing advance, a difference might occur which would cause what your guy described.

Just a thought--

 

I had my car in for service today and the tech put on a TSB software patch that he said would smooth this out.
