Pathfinders can make a very loud whining noise from the Electronic Power Steering Unit. It is VERY annoying, and very loud - you can hear it clearly from inside the vehicle. The proposed solution is to replace for $3,000, but the dealer will install an "insulator" for $150 that greatly lessens the noise. They couldn't promise me that the new part (same as the old part) won't also quickly fail - it is a Nissan problem.

So, it is ridiculous that they use a part that makes so much noise on a LOT of Pathfinders, but, they tell me that the functionality of the part is good, it is just LOUD.

The annoying high pitched whistling noise coming from what I was told by Nissan service department as the normal operation of the electronic power steering is ridiculous to say the least. The new styling of the Pathfinder led my wife and I to purchase the top-of-the line Platinum edition after owning Acura MDX’s for our last three SUV’s, and now I can honestly say we made a big mistake. I would truly trade this car in for another MDX if I wasn’t going to take a financial bath. Among the other rattles throughout the vehicle, the power steering sound is by far the worst. It literally sounds like a running airplane sitting on a tarmac. For the price I paid for my Pathfinder, it should be made much better. I refer to it as a tin can on wheels. Buyer beware if you are considering a Nissan Pathfinder or any Nissan for that matter.

Purchased a new 2015 Platinum Pathfinder. All of the sudden, very loud high pitched whistling coming from under the hood could be heard. The noise can be heard inside the car when the engine is running. Extremely loud when hood is open.

Took the vehicle into the Nissan service department where I purchased the vehicle. Was told the noise is from the electronic power steering and that all 2015 Pathfinders make the noise.

The noise has not “always been there” as the service shop told me. I didn’t “just start hearing the noise” as the service shop suggested.

This is complete BS. Brand new vehicle, 5165 miles, and now it makes a high pitched noise that can be heard in the car and is hard to talk over when the hood is up.

NISSAN, THIS IS NOT GOING TO WORK!

Traded old Pathfinder for new, higher level model. Haven't even put the plates on yet. The car vibrates/ hesitates when accelerating.. whistle noise connected in some form to steering, a loud low tone hum when I use the brake, take my foot off the brake to slowly move forward or backwards. Sound is worse when turning left. The vibration is constant, driving or at a standstill you feel it thru the entire car, concentrated in front part of car.

I am looking into turning it back to dealership and replace, but if it costs me more money I may rather spend any extra money on an attorney instead of giving it to the dealership. I'm also contacting the owner of the dealership as soon as I have the information. I'm hoping that the dealership will back the product they sell in good faith and as a 'new vehicle', and do what's right and that is give me a new vehicle that does not have immediate issues and take back the one I just paid over 45k for.

I've researched complaints, problems, call it what you want, that have to do with the Pathfinder and have found this transmission and vibration/shudder issue existed well before 2015 and yet nothing was disclosed to me at the time of purchase that it was a potential problem. Just the same as they gave to tell you if a car has been in an accident (which we assume they do). In any case they need to make good on the vehicle they sold to me. I guess if I have to my last step will be calling my attorney.
