I have a 2005 Honda Civic that I bought certified pre owned. Over the past few days, I noticed that when I accelerate over 25 mph or so, the car starts to sound like a motor boat or like someone is riding a moped next to my car. It sounds the same if I am going 35 mph or 65 mph. When I accelarate the noise doesn’t get louder, its a constant level once I’m over that 25 mph mark. When I slow down to stop at a red light it winds down and stops. When I idle, I hear no noise except the normal engine sounds. What’s going on?? ---

Megan, I Would Get It Checked Out ASAP In Case It’s Something That Can Cause Damage To the Car Or Become Dangerous. This could be anything from a vibrating heat shield to a bad bearing in a wheel or drive train. I’d be amazed if anybody could perform a cyber-diagnosis of this problem with 100% accuracy. You’ll need to take it to a competent mechanic and have it properly diagnosed, the sooner, the better. So, go take your favorite mechanic for a ride. CSA ---

In addition to the possibilities mentioned by CSA, this could also be a leaking exhaust manifold, and that is a potential safety issue because it can lead to high carbon monoxide (CO) levels in the passenger cabin. This car needs to be checked out by a competent mechanic a.s.a.p. Please note that the category of competent mechanics does not normally include Midas, Meineke, Monro, Sears, Pep Boys, AAMCO, or any other chain operation. ---

I am willing to bet you have a cracked exhaust manifold or another type of exhaust leak. You did get this car checked out by [u]your[/u] mechanic before you bought it, right? “Certified pre-owned” is just a fancy term that means “used.” ---

It was a bad wheel bearing! Thanks again for the input ---
