'07 Pathfinder LE 4x4
i recently noticed a high whining noise when i accelerate. i took it to my mechanic and he told me the engine sounds fine. i just got the oil changed and have 57,500 miles on it (i did a lot of driving for my old job). any suggestions what this may be? it is very audible when driving at low speeds, but can still kind of hear it when travelling 55mph+. if i turn up the radio, i don't hear it at all.
you could find its your tyres..i had new ones on the rear, all terain tyres are kinda whiny
I agree, it might very well be the tires. I had something similar sounding happen to me a few months ago. Mine is an 06' Pathfinder LE, with 32,456. Silver on graphite, love it, but my lease is up in February 2010, so sad
I know this is late (considering the last post date), however for other Nissan owners seeking insight, it is probably your "timing chain guides". The original OWN guides were designed with a flaw. In addition, the high rpm's at startup & lack of oil pressure also exacerbates the issue. If you "Google" it for your vehicle (Xterra, Frontier, Pathfinder with 4.0L engine), you will find that Nissan sent "technical service bulletins" to the dealers, but never advised consumers. I suggest (to those affected) to call Nissan Consumer Affairs & file a complaint. I believe they knew about it (based on service bulletins sent) & hoped to "charge the customer" for not knowing any better. (FYI - Estimated cost to repair my 06 Pathfinder LE = $1250). Maybe more complaints & potential loss of future Nissan owners may get them to reduce the cost (usually worked out with your local dealer) or heck, a TRUE RECALL with reimbursement for those who PAID already. Hope this helps someone. Don't be a victim!
