I bought my vehicle in the end of 2007. I have loved my vehicle to date. Recently I started experiencing a shaking, shuddering when I let off the gas and then go to accelerate again. It appears to happen at about 40 mph. I have found out that it means I am going to have to have the torque and transmission replaced. Apparently this is common on the 2006 and earlier MDX. I am not at all happy and am now looking for a new vehicle, since this is a $7000 repair and I have no warranty. Apparently there is a recall on vehicles 2005 and earlier for the converter torque. Very disappointed since I bought this vehicle to keep long term.
