Repair & Service Tips        

Find out what to do when your car is not running right.
Check out and compare your symptoms.


The more you know about your vehicle, the more likely you'll be able to head off repair problems. You can detect many common vehicle problems by using your senses: eyeballing the area around your vehicle, listening for strange noises, sensing a difference in the way your vehicle handles, or even noticing unusual odors.

Looks Like Trouble
Small stains or an occasional drop of fluid under your vehicle may not mean much. But wet spots deserve attention; check puddles immediately.

You can identify fluids by their color and consistency:

Smells Like Trouble
Some problems are under your nose. You can detect them by their odor:

Sounds Like Trouble
Squeaks, squeals, rattles, rumbles, and other sounds provide valuable clues about problems and maintenance needs. Here are some common noises and what they mean:

Squeal - A shrill, sharp noise, usually related to engine speed:

Click - A slight sharp noise, related to either engine speed or vehicle speed:

Screech - A high-pitched, piercing metallic sound; usually occurs while the vehicle is in motion:

Rumble - a low-pitched rhythmic sound.

Ping - A high-pitched metallic tapping sound, related to engine speed:

Heavy Knock - A rhythmic pounding sound:

Clunk - A random thumping sound:

Feels Like Trouble
Difficult handling, a rough ride, vibration and poor performance are symptoms you can feel. They almost always indicate a problem.


  • Misaligned front wheels and/or worn steering components, such as the idler or ball joint, can cause wandering or difficulty steering in a straight line.

  • Pulling - the vehicle's tendency to steer to the left or right - can be caused by something as routine as under-inflated tires, or as serious as a damaged or misaligned front end.

Ride and Handling

  • Worn shock absorbers or other suspension components - or improper tire inflation - can contribute to poor cornering.

  • While there is no hard and fast rule about when to replace shock absorbers or struts, try this test: bounce the vehicle up and down hard at each wheel and then let go. See how many times the vehicle bounces. Weak shocks will allow the vehicle to bounce twice or more.

  • Springs do not normally wear out and do not need replacement unless one corner of the vehicle is lower than the others. Overloading your vehicle can damage the springs.

  • Balance tires properly. An unbalanced or improperly balanced tire causes a vehicle to vibrate and may wear steering and suspension components prematurely.

Brake problems have several symptoms. Schedule diagnosis and repair if:

  • The vehicle pulls to one side when the brakes are applied.

  • The brake pedal sinks to the floor when pressure is maintained.

  • You hear or feel scraping or grinding during braking.

  • The "brake" light on the instrument panel is lit.

The following symptoms indicate engine trouble. Get a diagnosis and schedule the repair.

  • Difficulty starting the engine.

  • The "check engine" light on the instrument panel is lit.

  • Rough idling or stalling.

  • Poor acceleration.

  • Poor fuel economy.

  • Excessive oil use (more than one quart between changes).

  • Engine continues running after the key is removed.

Poor transmission performance may come from actual component failure or a simple disconnected hose or plugged filter. Make sure the technician checks the simple items first; transmission repairs normally are expensive. Some of the most common symptoms of transmission problems are:

  • Abrupt or hard shifts between gears.

  • Delayed or no response when shifting from neutral to drive or reverse.

  • Failure to shift during normal acceleration.

  • Slippage during acceleration. The engine speeds up, but the vehicle does not respond.


Car trouble doesn't always mean major repairs. Here are some common causes of trouble and techniques to help you and your technician find and fix problems:

  • Alternator - Loose wiring can make your alternator appear defective. Your technician should check for loose connections and perform an output test before replacing the alternator.

  • Battery - Corroded or loose battery terminals can make the battery appear dead or defective. Your technician should clean the terminals and test battery function before replacing the battery.

  • Starter - What appears to be a defective starter actually may be a dead battery or poor connection. Ask your technician to check all connections and test the battery before repairing the starter.

  • Muffler - a loud rumbling noise under your vehicle indicates a need for a new muffler or exhaust pipe.

  • Tune-up - The old-fashioned "tune-up" may not be relevant to your vehicle. Fewer parts, other than belts, spark plugs, hoses and filters, need to be replaced on newer vehicles. Follow the recommendations in your owner's manual.
