I have recently brought a 2009 STX and its great. Over time I will do some mods to it and plan to keep the truck for a long time. A friend of mine who has the same model had his timing chain break apparently without warning and now needs to replace his engine. I was wondering if there are any warnings ie a noise I should keep an ear our for. Also, it appears that this is an inherent problem with the Navaras from what I have read. Does anyone have any experience with Nissan coughing up the dollars to fix the problem because they are aware of it? I wonder why they haven't done a recall. I guess its cost.
