Well I have had almost each and every engineering defect in the Titan now, smelled coolant yesterday and sure enough, coolant down on the skid plate. Dealer told me we haven't replaced any of those, so I took him about 50 pages of posts from the forums to alleviate any problems later. They have been good really, I have the Gold warranty and it is covered, they don't have it in stock, so they gave me a rental they cover until it comes in and is fixed. 50721 miles, too many of these failing in this mileage range, then again, rear diffs, front diffs, radiators, axle seals (three sets of axles installed in mine), becoming a bit frustrated with the deal anymore. I told the dealer today, it will be real tough to consider another Titan with the problems that Nissan refuses to address, almost know what your problems will be and when now when you buy one, too much money to have to deal with it. Don't want it to happen like that, but the Titan I have now might be my last.
