Last month the car seemed to start slipping gears when I got up to around 40 miles per hour. It was sporadic and once I let me foot off the gas for a second it seemed to clear and be ok. I started to see a slow leak of what I thought was oil in the garage where I parked the yesterday. When I mentioned the leak to a buddy and also told him that my heater was not working, he said we should check the coolant in the radiator. When we opened the radiator cap, there was a slimy brownish sludge all over the bottom of the cap. That afternoon, I brought the car to the mechanic across the street and he said that I had a radiator failure of some that has caused radiator fluid to get into the transmission. This is where the brown sludge has come from. He said the car needed a new radiator and the transmission had to be flushed, dropped, and serviced and it would not guarantee that the transmission needed to be replaced sometime soon after. The entire thing he quoted me as costing $3K. I called my Nissan dealer where I had purchased the car from new in April 2007 and the gentleman in the service department seemed quite aware of the issue and informed me that the radiator replacement is under and extended warranty from Nissan, but I would still be out of pocket for at least a $2500 co-pay for the replacement of the transmission.

My 2007 Xterra with 62K miles began making a whining noise when accelerating. Not sure what it was I took it to the Nissan dealer where I get all my major services done.the technician took a look at the problem and within min notify me it is the timing belt chain and guides, known issue for my Nissan Xterra. When I ask him if he is sure he confirm he does few of this every month and that the problem is so known that Nissan has a service bulletin, with the title describing the issue and the symptom ! he has confirm the issue is with the plastic guide that is part of the design. Looking online I find many Nissan owners are experiencing the same problem. I am extremely disappointed with the Nissan brand and not sure what to do, if I replace the part, will it happen again as it is a design issue ? when buying the car, one of the selling point was that the car does not have a timing belt anymore but a chain! that will most likely engine itself. Calling Nissan customer service did not help and I am left with a $2000 repair due to a known issue and bad design.

Gas in car was at a 1/4 tank and service engine light came on went and filled tank up and gas gauge not working after driving the car twice the light went off and the gauge was working 3 days latter same issue. I do see where there was a recall for the 2005, 2006, 2008 and 2009 Xterra for the same issue but they failed to recall the 2007 year for the same issue. This should be recalled and fixed.
