Turning up the radio and ignoring the noise is not the best response when cars are making sounds they did not make when they left the factory! So, yes, the least you should do under those circumstances is have a professional take a look and determine what is causing the noise. It’s important for you to know if your car needs immediate attention or if it is something that can be taken care of at a later date.

Noises can be the symptom of many different issues going on with your car. If not addressed, the results can be inconvenience, such as the car stops running while you’re driving or does not start, to having something fail while driving that could lead to loss of steering control or not being able to stop the car.

Different noises indicate different problems. Squeaking, scraping and rubbing noises while the engine is running and/or the vehicle is being driven can be from something as serious as worn out brakes, a failing engine water pump, or failing wheel bearings, to something as simple as a shield that has come loose and is rubbing against a tire. Clunking and knocking noises while driving can be caused by worn out suspension control arm bushings to shock absorbers to broken engine mounts which secure the engine and drive train into the vehicle. These issues, if not fixed, will have a negative effect on your ability to control your car.

Whining, ticking or clicking noises heard while the engine is running and the car not moving or while driving can be caused from a failing driveshaft or drive axle flexible joints. This could also indicate that the engine is low on oil, the power steering low on fluid or possible internal engine wear.

Ultimately, unusual noises left unattended will lead to more expensive repairs down the road, more inconvenience and possibly dangerous situations for you and your passengers. Bring it in as soon as possible to your trusted auto technician and avoid unnecessary heartache!

By faithfully observing a maintenance program for your vehicle, and if there are no warning lights on (Check Engine or Service Engine Soon), you should pass the smog test the first time. Warning lights result in an automatic failure without any further testing being done, so if those lights are on, please take your vehicle to a trusted auto repair shop that can correctly diagnose and fix the cause of the light being displayed. Neglecting vehicle maintenance and then failing the smog test, generally leads to higher repair costs being incurred in order to get the vehicle to pass the second test. Maintenance is always better than repairs!

Your registration renewal notice may direct you to a Test Only station. Test Only stations are what the name implies: no automotive repairs can be performed at one of these stations. If you are not directed to Test Only, you can bring your vehicle anywhere that is a registered test station. Bringing your vehicle to a Test Only station, whether directed there or not, can be a better choice. Test Only stations are usually more objective. They have no incentive for the vehicle to fail, since they are not allowed to perform repairs.

You are NOT required to bring your new car back to the dealer for all maintenance and repairs in order to keep your manufacturer’s warranty valid. Many people have been told when they purchase their new vehicle that the warranty will be voided if they have maintenance or repairs performed by an independent shop, but this is not true!

It is actually prohibited by Federal Law for a new car dealer to either deny warranty service or even imply that warranty service will be voided if servicing or repairs are not performed at the dealership. The law is the Magnuson-Moss Act of 1975, Title 15, Chapter 50, Section 2301-2312. Look it up for yourself! Look under “Tie-In Sales” Provisions. A Google Search on the Magnuson-Moss Act will also bring up many Web sites that explain this Federal Code in less “legal speak”; this is a good explanation: http://www.mema.org/Document-Vault/PDFs/MEMA-Comments-RE-FTC-Magnuson-MossActReview-Oct-24-2011-FINAL.pdf

Your own car manual even tells you that your vehicle’s maintenance may be performed by any automotive repair establishment or individual without invalidating the manufacturers’ warranty. Look under Vehicle Maintenance and Care, Maintenance Providers, Where to Go for Service and Replacement Parts, just to name a few areas in the manuals where you will find this confirmed.

For example: under Replacement Parts it says “Warranty coverage is not dependent upon the use of any particular brand of replacement parts.” Or, under Maintenance: “When maintenance and repairs are paid for by you, these services may be performed by you or by any automotive service provider you choose.”

Have you ever wondered how well a vehicle is being serviced at a facility whose primary purpose is to sell you a new car every 3 – 5 years? You may prefer a service provider that wants to develop a long-term relationship with you and help your vehicle stay healthy for 10 years or more.

The next time you are told that a new car has to be serviced at the dealer or the warranty will be void, mention the Magnuson-Moss Act (1975), and say “It just isn’t so!”

Just as it is wise to take good care of our bodies, investing a little time to pay attention to the needs of our cars will result in our cars living a long life for multiple 100′s of thousands of miles. Just changing the oil, although that is critical!, is not enough. Especially with the latest technology being used in modern vehicles, it can be easy to forget regular check ups, so make sure that wherever you do take your car for service has a reminder program in place to help you remember. Your car may seem to be running just fine. But ignoring recommended services at the proper mileage intervals can result in expensive repairs you could have avoided. Of course, the chances for success are greater if a good car regimen begins when your car is new, but starting now is better than not starting at all!

1. It is usually better to buy a vehicle from a private party than from a car lot. Especially if the car is being sold by the original owner and they have records of the vehicle services that have been done. Vehicles that are sitting on used car lots generally were purchased at auction and will not have their service history with them.

2. Buying the vehicle from the owner also allows you to see/observe how that person may have taken care of the vehicle. For example, if the car is at a personal residence when you look at it, how is the upkeep there? Where is the residence? Near the beach? Possible hidden corrosion. In the hills? Possible extra wear and tear on the drive train and brakes.

3. Service paper work is valuable in order to determine that the important services were done at the right time intervals. This is the most reliable way to determine the likelihood of the vehicle lasting many more miles for the least amount of dollars. Poorly maintained cars cost more over their lifetime. Without the service history, you have no way of knowing, for example, when the oil was last changed.

4. You can inspect the exterior of the vehicle. If the tire tread is worn unevenly, this suggests possible suspension repairs will be needed. Look at the body from different angles in the sun and shade. If the shade of paint looks different on the fender versus the door, for example, it could indicate accident repair.

5. Look under the hood. In the engine compartment, a battery with corrosion, white or green on the terminals alerts you to the possibility that a new battery is needed.

6. Check the vehicle fluids – transmission, power steering, and brake system. Dark or black in color is not good. Engine coolant should not be rusty.

7. Finally, drive the vehicle both around town at slow speeds and on the freeway at higher speed. Any vibrations or noises could mean something is worn out. If you feel vibrations when applying the brakes, it means the brakes need attention.

If the vehicle passes your inspection, then it is a good candidate for a more thorough and complete inspection by a professional.

Yes, this could very well become a dangerous situation. If your vehicle’s tires are not staying in constant contact with the road, control of the vehicle is seriously compromised.

What would cause something like this? Most likely, the bouncing tires indicate worn out or broken shock absorbers. Unfortunately, shock absorbers are one of the most overlooked wear items on vehicles, even though they are the next most important safety items after your brake system. The purpose for shock absorbers is not just to provide a more comfortable ride, but to serve to control the suspension movement so that you, the driver, have more control of your vehicle when braking or steering.

Here’s what can happen if your shock absorbers need to be replaced:

1. Body roll (side to side movement) which adversely impacts handling and control.
2. Loss of traction, which increases stopping distance and negatively affects control and acceleration.
3. Tire cupping/uneven tire wear, which shortens the life and performance of the tires and can cause road noise.
4. Nose dive when brakes are applied, increasing stopping distance, negatively affecting control and can result in premature front brake wear.
5. Bottoming out going over bumps, which negatively affects vehicle handling and control, resulting in premature wear of the suspension components.
6. Acceleration squat (the rear of the vehicle drops upon acceleration), which adversely affects traction, and vehicle handling and control.

In most cases, by the time a vehicle has 50 – 60,000 miles on it, the shocks (or shock absorbers/shock struts) have deteriorated to the point that new shocks will have a noticeable, positive effect on your vehicle’s ride and control.

This wear on your shocks happens so gradually that you may not notice until the shocks are so worn your vehicle is dangerous to drive. About 80% of vehicles in the wrecking yards still have their original shocks, and most were candidates for replacement at least once. If you experience/observe “vibrations” and “bouncing tires” with your vehicle, I encourage you to have your shocks inspected by a shop you trust as soon as possible.

For many of us today, the economic climate is prohibitive to buying a new car. Keeping the car you have healthy, reliable, and fun to drive is not difficult. It just means spending a little time getting to know your car better and following a simple maintenance program.

Most vehicle manufacturers recommend a regular interval service routine. Either check your car manual, or call your trusted automotive shop to learn what those intervals are. In general, it is best to bring your car in for service at 4k, 30k, 60k, 7500k, and 90k mileage intervals. Each service will be an opportunity for your vehicle to be checked and for any problems to be identified.

In between maintenance services, you can help prevent large repair bills by doing the following:

1. check your oil level
2. check your fluid levels (brake, coolant, power steering)
3. check tire pressures
4. keep track of time and mileage on your timing belt.

Also, stay in tune with your vehicle; listen for unfamiliar noises, especially when brakes are applied, when turning corners, when driving at high speeds.

Very important: if a check engine light appears on your dash board, don’t ignore it. Schedule an appointment with your trusted auto shop to determine what has caused the light to turn on.

Sticking to a routine maintenance schedule, monitoring fluid levels and tire condition, and listening to and acting on your vehicle’s complaints will result in a car that will serve you for as long as you want it to. It will also save you significant dollars in repair bills over the long term.

Not necessarily, and No! There are many reasons why your air conditioner may not be working correctly.

For one, temperature controls may not be functioning as they should, which has nothing to do with the system charge (refrigerant level).  If the system charge is low, there is most likely a leak somewhere in the system. This leak allows air and moisture to get into the system as well as loss of refrigerant. If the cause of the leak is not repaired and the air and moisture are not purged from the system, the refrigerant will mix with the moisture and create hydrochloric acid. This acid will deteriorate the components of the system from the inside out. Not good!

If your air conditioning system is not performing correctly, please have it examined by a professional with the correct equipment to both diagnose and repair the system defect. The most critical piece of equipment that is required is a refrigerant identifier. There are only two types of refrigerant that should be in an automobile’s A/C system (depending on the age of the vehicle):  R-12 (older vehicles) or R-134A. If anything else is put into the system, it is considered contaminated and must be removed from the system and handled as contaminated waste. As an example, if your system is using R-12 and another type of refrigerant is added, there is the potential for serious damage to your vehicle.

There is also equipment needed to check the operation of the A/C system that is dedicated to either R-12 or R-134A,  as well as equipment that checks for external leakage of the refrigerant and finds the source of the leak.

Be aware that many quick lubes and repair facilities may be putting the wrong refrigerant into automotive A/C systems because of a lack of knowledge, training, or correct equipment, so don’t hesitate to ask your shop if they are using the correct equipment before they work on your vehicle.

Do you know which A/C refrigerant is the correct one for your car?

The culprit? His cabin air filter. Even though this filter is a common piece of equipment in today’s vehicles, it is often overlooked during a routine service.  It’s important to understand that failure to change this filter periodically will have adverse effects on the health and safety of the vehicle occupants, reduce the efficiency of the vehicle’s heating and air conditioning system, and even hasten the demise of certain vehicle parts.

This filter is located in the air intake for the passenger compartment and filters dust, pollen, dirt and other allergens from the incoming air. At the same time, it prevents leaves, bugs and corrosive debris from filtering into the heating, ventilation and air conditioning systems, which would affect performance. The buildup of leaves and debris is usually the cause of the foul smell you are experiencing.

There are different types of cabin filters to fit most vehicles. The standard filter traps most particles larger than 3 microns in size. A better filter is electro-statically charged so that it can trap particles as small as 0.3 microns. The best of the cabin air filters contain activated charcoal, which helps remove odors, fumes and gases.

The easiest way to determine if a vehicle has a cabin air filter is to check the owner’s manual or ask a service technician.  These filters are usually located behind the glove box or under the hood near the base of the windshield, and are reasonably easy to change.

The result of not changing the filter is a gradual buildup of contaminants, which will prevent it from properly filtering the incoming air and result in foul smells, bacteria, and allergens entering the passenger compartment. Additionally, when less air is able to pass through a clogged filter, it negatively affects the performance of the air conditioning/heating system and makes the components work harder, leading to a shorter useful life.

Are you aware of the cabin air filter in your car? Do you know when it was last changed?
