Hello All,

As of recently, my 2011 Nissan Maxima SV has been making some strange noise. I notice it happening when I accelerate between 18-20 mph and when the door locks kick in. Happens almost every time. Sometimes it doesn't do it making me assume it shouldn't be doing it in the first place. The noise sounds like it is coming from under the front of the car almost like a piece of plastic flapping or clicking "clack clack clack clack clack clack" and fades away. I have a friend with the same car, actually a 2010, and he doesn't hear the same noise. Googled the hell out of this one and nothing. Called the dealer and they said to bring it in. Does anyone have the same noise or possibly know what it is? Also, does anyone know how to set the door locks to lock when shifting into gear ie. R or D rather than while the car is moving? Any help would be much appreciated! Thanks in advance

ABS SELF CHECK NOISE

APPLIED VEHICLES: All Nissan Vehicles with ABS or ABS/VDC

SERVICE INFORMATION

If you identify:

^ Clicking, knocking, clunking, buzzing, or thumping noise coming from the engine compartment area; and

^ The noise occurs only once during the first few seconds of driving at approximately 16 MPH; and

^ The noise occurs only once per ignition cycle (ignition OFF > ON) and does not occur again until the ignition is cycled.

NOTE:
The noise may be louder after the vehicle has not been operated for a prolonged period of time.

The above condition is normal and does not need repair.

Each time the ignition is turned on and the vehicle is driven at about 16 mph, the ABS/VDC system performs a "Self-Check" to confirm components of the ABS/VDC system are operating correctly.

This "Self-Check" function creates the noise described above.

If the brakes are being applied when the "Self-Check" occurs, a vibration may be felt in the brake pedal and an increased level of noise may be noticed.

NOTE: ^ Refer customers to the Owners Manual, Section 5, Starting and driving, Brake system on the Anti-Lock Braking System (ABS). The "Self-test feature" section provides additional explanation.

^ The speeds described above refer specifically to Versa, Sentra, Altima, and Maxima. However, any vehicle fitted with ABS or ABS/VDC will have a "Self-Check" which is triggered in similar circumstances.

Thank you!!!!
