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.

Somewhat high-pitched whine from engine - also - distinct knocking during acceleration when cold
I first started noticing this whining/whirling noise at about 60,000 miles. It seems to have got worse over time. I recently visited a local Nissan dealer and they told me there was a service bulletin put out stating the problem is probably caused by a secondary timing chain/s. The dealer quoted me a cost of over a thousand dollars! From what I understand they are not over willing to help out those in need, we'll see. I'm going to try and get them to fix it, if not I will take other action. I'll be a horses ***, if I'm going to pay for another bad design flaw on Nissan's part, NO WAY NO HOW. It's time they started taking responsibility for their lack of quality in todays vehicles. I'm so disappointed in Nissan, almost to the point of disgusted. I don't think I will ever buy another Nissan product ever. What ever happened to this company!

Tend to hear it when the transmission shifts. If still under power it will continue until the engine RPM drops back a bit.

On start up the engine has a whining and loose rattling sound. Once the engine warms up it's not so bad put you can still hear it.

whining noise from engine, most notable during acceleration. I'm a Honda mechanic, so I'll be doing this repair myself when i get a spare day to do it. It sounds like a pain!

The noise was noticed before reaching 3000 miles but I didn't realize that it is a serious problem because I heard some other vehicles had the same noise until reading this page. Thanks for the information. I will contact the dealer and see what they are going to say about it.
