I have a 2012 nissan sentra SR, only 5 months old, 7,000 miles so far.. bought it brand new.
A few days ago, there was this loud rattling/vibrating noise coming from my engine when i would turn the AC on, however it would stop after a few seconds. I took it to nissan, they said it was the compressor, and for some reason it was very noisey, SOO.. they replaced it, under warranty thankfully...
Well, i got the car back last night, no issues.. until today- the sound is still there! Its not as loud, and not all the time as before but it definitley is there still. It happens about 5-10 sec after turning the AC on, and it only lasts a few secs.. as before.
The car is brand new like i said and has never had any issues til now.. The ac also works very well, its just that noise!
Im taking it back to nissan tomorrow.. in hopes they can figure it out... but does anyone have any suggestions?!
I also recorded the sound on my iphone! if i can figure out to upload it before the issue can be looked at again, i will.
