What your car is really saying

Chances are, your car won't talk to you if it's got a faulty accelerator pedal, as millions have recently discovered in the massive Toyota recall, but your baby will speak in volumes when other problems crop up.

Still, it's tough for you to interpret what your car is babbling about when it goes thump, bump, bang, wonk, wang or wank.

Lucky for you Consumer Reports has stepped in to decipher car talk and let you know when not to worry and when to call your friendly neighborhood auto mechanic.

Listen closely.

Squealing brakes. Not to worry. Mice aren't inside your wheels. Squealing during light braking typically won't affect your ability to stop your car, but it could mean brake pad vibration. Even new pads can squeal. A high pitched squeal while the car is moving could be a sign your pads are worn -- even if the car subsequently stops when you hit the brakes. In either case, have a mechanic check them, Consumer Report advises.

Grinding sound from brakes. Drive straight to the mechanic. Better yet, consider a tow, especially if you haven't used your auto club towing service for a while. It won't cost you a cent for the tow (with certain auto club memberships) and it's better to be safe than sorry -- even if you have to pay for the lift. When your brakes grind, your car is unsafe to you and others on the road. Because you've waited too long, expect a higher repair bill than if you'd replaced those pads earlier. When the brake pads wear down what's left grinds against the brake rotor and begins to eat it. Now you may have to replace the rotor and get new brakes.

Squeals under the hood. Your cat is safe. What can sound like prolonged chalking on the blackboard, especially when you rev the engine or during cold starts, often means a drive belt is slipping. You may need a mechanic to adjust it or replace it if the belt looks shiny and glazed.

Light engine rattling. No, your kid didn't drop a bag a marbles into the engine. Could be pinging. Sounds like tiny ball bearings in your engine. Listen when you are accelerating or driving uphill. You may be saving a few bucks on that low octane fuel or, if you car is older it could be suffering carbon buildup. If the pinging persists your engine could pay -- and so could you. First check your coolant's temperature. Add more if necessary. Also try switching to a higher octane. Otherwise, call your mechanic, says Consumer Reports.

Rhythmic thumping. If you are driving on a smooth roadway and the noise increases and decreases as you accelerate and decelerate, stop and check your tires for torn rubber, sidewall bubbles and flat spots. Tears and bubbles can become nasty blow outs. Get new tires. Torn rubber or a bubble could lead to a blowout. Don't hesitate to have flat spots checked, though they may not be serious. Also for shaking, vibrating steering, especially at higher speeds, you may need your wheels balanced or an alignment. See your mechanic.

Hissing under the hood. It's likely not a snake. Consumer Reports says you likely have a vacuum leak, caused by a worn, cracked or disconnected hose. Chances are your vehicle's engine is also running or idling rough. The "check engine" light is your car's sign language. If it's on, it's trying to tell you something. You may be able to reconnect a disconnected hose, but if you need to replace it, a mechanic is better equipped for the job. Also, hissing could be your coolant boiling over. Let the car cool, add more, see a mechanic for radiator problems.
