Mercedes-Benz automobiles are engineered to be reliable, long-lasting vehicles. But even the most robust machinery requires periodic repair. A Mercedes is notoriously expensive to fix and maintain, and requires highly skilled mechanics with specialized equipment. As with any vehicle, a bad repair job can lead to spectacularly expensive consequences, and potentially dangerous situations.
Authorized Mercedes-Benz dealers are perhaps the most qualified to perform repairs, but are usually quite expensive. If the vehicle is older, or beyond the warranty period, you may choose to go with one of the many independent shops specializing in Mercedes repair. These shop are often less expensive than dealers, and many do excellent work. Before choosing a shop, ask for mechanic credentials and references from other Mercedes customers. If your car is under warranty, only authorized repair facilities are able to handle the work.
The head mechanic should be ASE (American Service Excellence) certified, and have credentials from Mercedes-Benz as an authorized service technician. Mercedes has a strict and comprehensive training program for mechanics.
Ask the shop service manager if the facility has authorized access to the latest Mercedes computer software downloads -- this is extremely important, since software runs and monitors most every system on a modern Mercedes, and is updated regularly.
Mercedes parts are manufactured to strict tolerances. While OEM (Original Equipment Manufacturer) parts are expensive, they are designed to provide long service life, and are compatible with other parts in fit and operation. Aftermarket parts for older cars are sometimes available at prices substantially lower than OEM parts. While there are many excellent aftermarket manufacturers, there are inferior parts as well. Some parts are not warrantied, and may not provide comparable service life. Ask the service manager if OEM parts will be used, and ask for an explanation if aftermarket parts are specified. If budget allows, always insist on OEM parts, and ask to see the packing list or original packaging. It is common practice for mechanics to return, or allow viewing, of the parts that were replaced, but it should be mentioned to the service manager before work begins.
Always insist on written estimates for all repair work, and read the service agreement before signing or authorizing work. Of course, it is not always possible for mechanics to fully realize the extent of every repair until work commences, so the possibility for additional parts and labor should be expected. Verbiage to this effect is normally stated on the service agreement.
Preventative maintenance is the key to long life in a Mercedes-Benz. Your owner's manual will provide a list of service intervals, which should be followed methodically. Regular oil, fluid, and filter changes, tire rotation, belt and hose services, air conditioning recharges, software upgrades, and other normal maintenance procedures, will help prevent breakdowns and protect vital systems from failure.
A new Mercedes is obviously expensive, but many used models are comparable in price with other vehicles. If purchasing a used vehicle, insist on viewing repair and maintenance records. If papers are unavailable, consider purchasing from another seller. Working out problems can add thousands of dollars to your purchase.
Repairs and parts on older models are just as costly as newer models, and should be anticipated. Budgeting and putting aside a little money every month will lessen the financial burden when repairs and maintenance are necessary. A well-maintained Mercedes will provide many years of reliable pleasure, performance and safety.
