 Bought new 6/2016. First couple thousand miles were great. My wife loved the Rogue. Then a chirp,chirp,chirp,chirp noise started at 63 mph especially when decelerating. No noise above 68. About 15000 miles now and noise is louder. Contacted dealer.(very good dealer) Road tested with their technician. He hears the noise. They replaced the front wheel bearings which they found to be noisy. NO CHANGE. Technician took new Rogue off of lot, drove, it had same noise as mine at same speeds.Gave me 1-800-nissan-1 number to call. Back and forth with friendly  Nissan factory reps. They will investigate and get back. They did. One week goes by. Met with factory rep at dealer. Went for a ride in my car. Same noise. Went for ride in new Rogue off lot.  Same noise. Rep says this is "inherent in the design of the car, cannot be fixed". I think this is a brush off by the factory for a known defect of this vehicle. Except for this the car rides harshly but has a great interior. NO MORE NISSAN. They (factory) know about this problem but it will take re-engineering to fix. Cheaper to stone wall the owners. Think about it. The manufacturer tells you they cannot repair your car? It is all about money. Nissan is apparently aware that there are several thousand just like this out there and it must be a frequency associated with a major component that would be expensive to replace. These vehicles are built in Korea and the US. Mine is Korean built. Look on inside of drivers door for information. This is a safety issue due to driver distraction. Vehicle has just over 23000 miles now and still makes same noise at a wider range of speeds. Never again. Fifty eight to sixty eight mph. The US built version may not do this.
