Abnormal Noise From Front of Engine on Nissan Pathfinder

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.

My wife's 06 with roughly 84-85K just started this noise two days ago, only on cold starts though... Almost sounds like gravel being thrown onto a piece of aluminum (like the heat sheild). Does that sound about right?

Knocking noise coming from from engine, and it sloping and idling night when it accelerates.. Noise is extremely high.
Verified for the Nissan Pathfinder A whining or buzzing type noise From the front of the engine. Found out there was a recall and had it repair at the local dealer. Just today the engine make a noice similar to air flowing through the engine almost like an air conditioner running in the engine department.

I just recently had my '07 Frontier in for regular service and was told by the dealership service rep that I needed to have the timing chain replaced to the tune of $1800. I have had the truck serviced regularly at all appropriate intervals by this same dealership. Now they tell me this needs to be fixed. I'm very disappointed and frustrated at Nissan for not generating a recall/repair on such a major problem with their vehicles. From what I've been able to read this is way too common a problem for them to ignore and not resolve for their customers. Until this happened, I had a very good impression of Nissan vehicles; now I'm not so sure. They cut corners and are capable of building junk just like all the others. Overall I've been very pleased with the truck and it's been nearly bullet proof (except for having to put two batteries in it over the last 3 years and this dealer replacing the rear breaks when they should have replaced the front brakes). Really angry and frustrated about this situation - it's not like you can't leave the issue unaddressed but I hate the fact that I'm supposed to pay $1800 to have this fixed, a basic engine component that should be covered under warranty.

Noise sounds like a motorcycle is following you at a distance but no motorcycle present. Noise does not vary with a push on the accelerator it seems linked to the speed starting around 10

same problem. Had timing chains and tensioners replaced 5 months ago and now its doing it again!!!!

I have an 08 Pathfinder that made a lot of noise when it turned on. Found out it would be the timing chain and cost me $1800 to repair. I do also find it ridiculous that this is a common problem, and Nissan has done little to nothing to resolve this problem. They did fix the transmission problem without charge and this should also be included. I shouldn't have to pay over $1800 for a car with a little over 80,000 miles. Nissan need to do the right thing... ASAP.

Two years ago, dealer recommended replacing the timing chain for about 2 grand (they have to basically take the entire front end apart to get to it). Engine has a higher pitched whine than it did originally. Timing chain is not a service item so obviously this is a vehicle defect and the company isn't standing behind its car.
Timing chain - loud buzzing. $1750. Ouch

Noise started 2014, still trying to get it fixed. Loud noise coming from front. 3 Mechanics including dealership says timing chain
2008 Nissan Pathfinder - 4.0L V6 96,000 mi,
the engine stopped running going down the highway at 55 MPH had towed to shop were they told me the timming had jumped and destroyed the engine. There is no recall so I have to save money to get it fixed and rely on trying to borrow a freinds car to go to work. No more Nissians for me. Jim

Thought it was the transmission starting to go out, but after doing research online found out it's the timing chain.
