I have a Kia Sorento 2.5 diesel. I have noticed an unusual rattling noise a bit like when you shake a paint aerosol can. It occurs at around 1900 revs or 30mph in third gear, 40 mph in fourth gear and 50 mph in fifth. The noise disappears if I increase or decrease speed in the appropriate gear by 5 mph or change down or up a gear. Has anyone any idea what is happening? I think it is mechanical as I don't think it is a rattle from something loose in the engine compartment.

Hmmmm...


Rev butnot speed related would suggest something in the engine or enginebay - have you checked the main plastic engine cover fixing studs may be loosethey should also have rubber damping washers to stop vibration, if left loose the movement will eventually strip the thread ?



Just a thought - good luck finding it
