A whining or buzzing type noise may develop from the timing chain area caused by excess slack in the secondary timing chains. Nissan has issued a service bulletin (NTB09-128) regarding this issue. Replacement of both secondary timing chains and their tensioner shoes will be necessary to repair this concern. As part of this repair, the engine oil and filter should also be replaced.

I have the same problem with my 2007 Xterra. I have the service bulleting and have done some research and found that Nissan will cover this repair for vehicles past their warranty on a case by case basis. My request for repair was denied, which I obviously do not accept. Nissan would not disclose the reasons, but said it was many factors. I inferred the factors were individual based, and not based on the nature of the problem which I believe is incorrect. My research indicates this is an extremely pervasive problem which should have been a recall. I believe this warrants a Class Action Lawsuit which I will be looking into the next few days. I appreciate any inputs that will assist in this effort.

I have a whining sound in my engine, thought might be the belt but not sure. the noise happens when starting the engine when its cold but once the engine runs for a while the noise begins to get lower and lower until you don't hear no more.
Same noise as the others in forum describe. Brought to my mechanic and the timing chains need replacement. 9 hours of labor involved. Currently being fixed. Anticipated bill around $2000. If class action lawsuit is started I am in.

I also have a whining bussing noise coming from my drivers left front motor side. Is this the timing chain that costs almost 2000.00 to fix. There should be a recall on this problem.

My 2007 Nissan Xterra just started to emit a loud noise from the engine. The Nissan dealership and my Uncle have both diagnosed the problem: the Timing Chain. My Uncle said with such low mileage on my vehicle, regular oil changes at every 3k miles, this should not be an issue. I have found in my research that this appears to be a re-occurring design issue for 2007 Nissan Xterra (NTB09-128). At this time, I have been told I need to replace the timing chain engine which will cost $2k. I am currently going to put a complaint in with Nissan Customer Service.

I had this buzzing and whinning sound since June of 2007. I took my X-terra in and they changed a driver belt and a tensioner assembly and had to pay 92.02 minus my deductable which was 50.00 and still paid 42.02 for nothing it still makes the same noise when you start the car. Very unsatisfied with Nissan service. Now my X-terra has over 120,00 miles and it still makes that noise. I don't understand why it's not being covered by my security + plus service plan, it's not expired yet.
whining/squealing noise coming from engine. I thought it might have been the belt so I replaced it and it seemed to help a little but within a month the noise came back.
When the problem began (and for around the first 6 months) the noise only happened on a cold start, would get higher pitch or faster with acceleration but within maybe 5-10 miles the noise would stop.
So whenever I would bring it to the dealership they were unable to hear anything (not that they would know what to do or replace the correct parts anyway).
Currently- over a year later the noise is pretty much constant and extremely loud.
Extra info... I don't know anything about the lemon law but I have had several problems with this vehicle, if anything frustrates me it is when a vehicle is not safe. One of the main reasons I bought this SUV was because of the safety ratings.
Out of the many issue this one bothered me the most because it put my safety at risk as well as other people on the road and that is something I consider unexceptionable. My VDC button/slip light would turn on by itself on a perfectly dry highway and I had to fight to stay on the road because the VDC would take over my steering. This happened several times (came out of nowhere) I would have to pull over on the freeway and turn the suv on and off.
I would have been a bit more satisfied if... when I called the dealership they would have told me to come in immediately and wouldn't have charged me over 500 just for a sensor (yes that's all it was, a sensor.)
On a positive note and besides all of the problems I love my Xterra it really is a great vehicle plus it's hard to find an suv with awesome ground clearance (no need for a lift kit) I could clear and plow through snow drifts like no other. If you want a Nissan Xterra get one but be smart get a lifetime warranty that covers EVERYTHING, have it inspected before you buy. If Nissan worked out all the issues I would buy another one in an instant! But because of all of the problems I find it to be more cost effective to buy a new vehicle.
This year expenses = about 4,000 (I included the average price of what it would cost to fix the whining/squealing...and now I am done whining I apologize for the long sh-peal. FYI I am not rough on the vehicle.
If you want more info or have questions please email me at Mnenoot@yahoo.com (In subject line please put NISSAN QUESTION?) I get a lot of junk mail and would hate to delete it by accident. Thanks.

Rattling sound from the engine on some acceleration and whining on start-up. Resolution is pending.
