Service FAQs

The best way to keep your Mercedes-Benz running at top performance is by performing required service at the proper intervals and quickly contacting our Service Center in Louisville, KY if something clearly goes wrong with your vehicle.  Below are answers to common questions we receive about servicing vehicles:

What is the Tafel Motors Loaner Car Policy?
There are a variety of conditions where we will provide a loaner car. Read more about our loaner car policy here!

How often should I get an alignment?
We suggest that the alignment be check at least once a year. We also suggest that an alignment check be performed when every new tires are installed.

What is the schedule of the complimentary Car Wash?

Monday-Friday: 9am-4pm

Saturday: 10am-2pm

My “Check Engine” light came on, what does that mean and what do I do?
There are many reasons for the Check Engine light to come on. The system monitors the operations of dozens of sensors. They may or may not cause the car to run poorly, but all indicate that the engine is not performing as it was intended. If your “Check Engine” light comes on we do suggest that you contact our Service Department so we can diagnose the problem.

How important is changing my engine’s oil?
Changing your engine’s oil and filter is one of the most vital maintenance procedures possible. Oil keeps friction down in the engine and prevents the motor from seizing up. Typical intervals for new cars are between 5,000 to 15,000 miles.

Engine coolant
Water and antifreeze keep your engine from overheating and freezing during extreme temperatures. Intervals for flushing the system and replacing coolant vary, as some manufacturers promise long lasting antifreeze good past 100,000 miles. A general timeframe would be every few years or 30,000 to 40,000 miles.

How often do you change spark plugs?
Older vehicles required the replacement or adjustment of spark plugs much more often than new vehicles do. Manufacturers today promise over 100,000 miles before a tune-up that includes changing the plugs. Still, checking the plugs at 50,000 to 60,000 miles is not a bad idea.

How long does  a battery last?
Changing a battery depends on the type of battery, type of vehicle and local climate. Super cold regions may require a more powerful battery for cold starting. Also, rechargeable batteries that have completely lost their charge at some point often never reach full potential again.

When should I change my windshield wipers?
Wipers need to be replaced, especially in climates with ice and snow. Sometimes just the blade needs replacing, while other times the entire wiper unit should go. Some customers may choose different types of wipers for better performance.

How long do brakes last?
Like tires, brake life depends heavily on driving style. Lots of stressful braking will significantly shorten the life. Replacement requires new pads and sometimes, new rotors.

How do I select the right tires?
Different seasons require different types of tires. Many manufacturers sell vehicles with all-season tires that are suitable for most conditions. However, if your vehicle arrived with performance summer tires you should invest in a set of snow tires for safety in the bad weather. Some drivers with all-season rubber may also fit snows for added security.

Always be sure to maintain the proper inflation for safety, performance and longevity.

How do I prepare my Mercedes-Benz for the winter months?
Be sure your engine oil is the correct viscosity. Colder climates can cause oil to thicken, demanding a thinner oil to start.

Check your antifreeze and be certain the proper water-to-antifreeze mixture is maintained. Antifreeze testers are available at many auto parts stores.

Verify that your windshield wipers are operable and keep the washer fluid reservoir full.

Double-check hoses and belts. Cold temperatures can cause rubber to shrink and crack, so be sure your hoses and belts have some flexibility left.

What are the conditions of my warranty?
All new and many used vehicles arrive with a warranty covering unexpected repairs. Be sure to understand the duration and covered components of the warranty. A typical warranty might be written “48/50,000” meaning that coverage lasts either 48 months from the initial purchase or until the vehicle has 50,000 miles, whichever comes first.

Are pre-owned vehicles still covered under factory warranty?
With every Certified Pre-Owned Mercedes-Benz comes peace of mind, because every MBCPO vehicle is backed by one of the most comprehensive pre-owned vehicle limited warranties available.  Click here for more information.
