The Federal Trade Commission estimates that $20,000,000,000
(that's 20 Billion!) of auto repairs are UNNECESSARY !!!
Partially due to fraud
Partially due to incompetence of repair shops.
The best way to avoid unnecessary auto repair is to
perform basic maintenance and have a
little basic knowledge of how your car works and how to identify common car problems. It's
also important to know how to select a good mechanic, the types of questions to ask, and
your consumer rights.
Please remember to always get a second or even third opinion.
According to the Federal Trade Commission (FTC), the American Automobile
Association (AAA), and the National Association of Attorneys General (NAAG), this kind of
information about your automobile may help you keep a lid on mechanical mistakes.
HEADING OFF CAR PROBLEMS
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:
- Look at the area around your vehicle
- Listen for strange noises
- Do you feel a difference in the way your vehicle Drives
- Do you notice unusual odors.
Take a Looks around and under your car.
Small stains or an occasional drop of fluid under your vehicle may not mean much. But
wet spots merit attention; check puddles immediately.
You can identify fluids by their color and consistency:
- Yellowish green, pastel blue or florescent orange colors indicate a possible overheated
engine or an antifreeze leak caused by a bad hose, water pump or leaking radiator.
- A dark brown or black oily fluid means the engine is leaking oil. A bad seal or gasket
could cause the leak.
- A red oily spot indicates a transmission or power-steering fluid leak.
- A puddle of clear water (normally from the left side under the car straight down from
the windshieldwiper area) usually is no problem. It is normal condensation from your
vehicle's air conditioner.
Learn to use your sense of smell
Some problems are under your nose. You can detect them by their odor:
Learn to listen to your car:
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:
- Loose or worn power steering, fan or air conditioning belt.
High pitch Squeal- Screech from front wheel area:
- Brake Pad wear indicator:
Roll Window down listen for noise from front wheel area at a low
speed.
Noise will stop in early stages if you apply brakes.
Have your front brake pads checked.
Click - A slight sharp noise, related to either engine speed or vehicle speed:
- Loose wheel cover.
Loose or bent fan blade.
Stuck valve lifter or low engine oil.
Rumble - a low-pitched rhythmic sound.
Defective exhaust pipe, converter or muffler.
Worn universal joint or other drive-line component.
Ping - A high-pitched metallic tapping sound, related to engine speed:
Usually caused by using gas with a lower octane rating than recommended. Check your
owner's manual for the proper octane rating. If the problem persists, engine ignition
timing could be at fault.
Heavy Knock - A rhythmic pounding sound:
- Worn crankshaft or connecting rod bearings.
Loose transmission torque converter.
Clunk - A random thumping sound:
Loose shock absorber or other suspension component.
Loose exhaust pipe or muffler.
Learn to Feel differences in your car
Difficult handling, a rough ride, vibration and poor performance are symptoms you can
feel. They almost always indicate a problem.
Steering
- 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.
Brakes
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.
-
Engine
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.
Transmission
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.
TROUBLE SHOOTING YOUR CAR
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.
