Nissan Pathfinder Problem Report
Nissan Pathfinder Abnormal Noise From Front of Engine
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.
Whining noise ,converter, electrical, fuel sensor,oil sensor, this is the worse car, Nissan will not get my business again and I will tell others not to buy any Nissan. - Visitor
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. - Visitor
makes loud whining noise and shakes over 40 mph and sometimes at 60 mph. i am so worried. - Visitor
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? - Visitor
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. - Mike Nat

Truck makes a whining noise when gas pedal is pressed. - Visitor
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. - Visitor
same problem. Had timing chains and tensioners replaced 5 months ago and now its doing it again!!!! - Visitor
Timing chain - loud buzzing. $1750. Ouch - Visitor
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 - Visitor
Whining noise. Called Nissan and right away the lady said it was the timing chain. Have to replace timing chain, guides and tensioners. Nissan charges $1750, Tuffy's charges $860 + parts, Bee's Auto in Clermont charges $650 + parts. - Visitor
Another costly Nissan defect in Pathfinder: Separate from transmission failure, and catalytic converter failures, and exhaust leaks, whining/whirl sound coming from front of engine - more pronounced at cold startup. Local Nissan dealer does not acknowledge issue, says nothing is wrong beyond a "loose heat shield." Same owner's other local dealership immediately identified problem. - Visitor

Whinning noise in engine when accelerator is pressed. It's very embarrassing. I notice it whenever the window is down, after the engine warms up. - Visitor
Whining sound during acceleration with increasing volume and pitch correlating with increase in speed. Sound goes away when I release the throttle. The sound can also be heard (albeit less intense) while coasting down hills. - Visitor
