has anyone experienced this? ive been getting a weird vibration it sounds like the windshield wipers or something vibrating but it isnt i cant find it, once the car slows down it goes away and then after driving for a few mins it goes away altogether and then a few days later ill hear it again and it will go away. anyone else experience this or am i going crazy?

 

would you describe the sound as a rattle? and sounds like its coming
from inside the dash?

if yes, its your hood bolts, there is a TSB for this,

also could be a bad water pump...

a video or audio recording and vehicle specs would help

 

Look at the exhaust heat shields under the driver and passenger. Mine were too close to the frame and exhaust in a couple of places
