Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

every summer I have this same problem with this car. It makes a very loud sound from under my hood. I have notice the noise is coming from where my air filter goes. I have made sure the oil has been changed and a new oil filter as well as a new air filter. Still when the car get hot it makes this loud horn noise. I can tell the noise has something to do with the air control system which flows thru my air filter.I am now checking my mass air flow sensor. My air works great and gets really cold so no problem here. With all of this said no one seems to know what the problem is and it has been a pain in the ass.

When idling or running the a/c a really loud humming comes from under the hood. It has done this since I have had it. Don't know what it is but it is very annoying to say the least. Doesn't seem to be anything major because it runs great. Just noisy!!
