Been hearing a noise when my 04 max is first key started and put in gear. (on first acceleration when I just start driving) Noise sounds like a solenoid valve or servo motor. Lasts about 1 sec

The dealer originally said it might be an electric motor mount and now tells me that it's ABS system self test. He says this is normal for the car and no repair needed.

Has anyone else ever heard this?

Should I press the dealer to fix or find another dealer (I am sure that if I drive a new Max I won't hear this noise!)

 

Mine does it as does my wife's Murano. I used to work for Nissan North America (factory rep) and had this issue brought to my attention from time to time by customers. The noise is normal.

 

Thanks factorymax Gives me some peace of mind to know it's not a malfunction.

Is this in fact an ABS test?

Any idea why it only occurs once I start accelerating (not on shift or keystart)?

 

It is an ABS test for sure.

The reason for the noise on acceleration is because the system needs motion of the rotor (ie: wheels) to proprly calebrate. If it did the self test when the vehicle was idling (wheels not turning), would not provide accurate test.

Hope that helps.

 

I hear something similar on my 2005 SE. When I engage the transmission whether going foward or reverse there is a one second or so hum. I'll assume this is what you are talking about.

 

I came hear suspicious of that. Funny how I have had the car 18 mos and just now noticing? After a fresh start, put in gear, I hear a quick gunting or vibration noise and feel it thru the brake pedal. My old Sienna did this and I am certain it was an ABS test. Any confirmation out there?
