I don't know if anyone can help me with this or not, but I'm hoping for some suggestions. I have a noise coming from under the hood that sounds exactly like someone is playing drums in a nearby house. Its a deep boom booming. You can't hear it from inside the van at all only when standing next to it. We had driven down a VERY dusty road earlier in the day and my husband thought maybe the air filter was clogged up or something. He changed both air filters and it is still making the noise. Its a 2006 SE if that matters. I dread another trip to the dealer, we have had so many issues with this van but for the last year it has been doing ok, I really hope this isn't the start of another ordeal.
