Replying to: morewasabi (Oct 28, 2006 9:42 am) Pretty similar to yours other than a recurring issue with brake rotors. 17k miles so far. Closer to 20 around town, but we've seen 18 at least once. Normally 22-27 highway depending on the length of the trip and the speed we drive. All time high of just over 28. Regular fuel, standard dino 5w-30 (free oil changes at the dealership for 3 yrs / 36k miles, so I go with it). Will be changing to Mobil1 full synth when that expires and I start doing the changes on my dime. Replies to this message: downlander (May 24, 2007 5:41 am)

Replying to: jerrywimer (Oct 30, 2006 4:12 am) My 2006 Uplander gets 16 around town with the 3.9 ltr.The steering has a knock that you feel in the wheel on sweeping turns(highway ramps) and it idles rough all the time. The dealer says it's fine,no stored codes. Apparently mechanics can't diagnose anything anymore unless the computer stores a code. Oh and did I mention that it hesitates and doesn't shift smoothly. Dealer says there is nothing wrong though. The dealer has replaced my rack and pinion and then new rack and pinion boots. There were Technical service bulletins for both problems.That lessened the knock so they replaced the upper intermediate shaft which did nothing because the problem came back twice after about 2 weeks. So now I bring it in about every month when the binding and knocking in the steering gets bad and they relubricate the upper intermediate steering shaft which lasts about 3 weeks and it all starts over again. The dealer says they are supposed to be coming out with a new shaft for the steering but he doesn't know when.Can you say LEMON!
