We brought our Nissan 2006 Xterra in to the boardwalk auto center. Redwood city, CA - Nissan to have them check on what we thought was another transmission issue (Nissan replaced the transmission, at their expense over $8000, once and the fuel gauge twice plus a couple of other recall items). When we picked up the car they told us we needed a new timing chain for about $2000 (we have heard these are not normal items to be replaced and should last the lifetime of the car). We can't believe there is yet another major expensive problem part with this car! when does this car become a lemon and how many major items are going to need to be replaced? what is happening to Nissan? has the timing chain issue been investigated and how many other people are having this problem?.
Noticed it the first time last night. I had just under a 1/4 tank of gas in my 2006 Nissan Xterra, and drove 15 miles and pulled over to use the phone. Left the engine running, and suddenly noticed the "service engine soon" light was lit, and the gas gauge read empty. Impossible, and illogical. Turned off the engine, turned back on. . . Same thing. Drove to gas station, filled up, made sure clicked the gas cap three times for proper seal. Gauge read that the gas tank was full, but the "service engine soon" light was still lit.
