Mercedes offers high-quality comfort, sophistication, and exceptional engine performance. Each model is manufactured using the best parts on the market. Several makes and models of Mercedes vehicles were manufactured using the V12 engine. In doing so, they have created a vehicle with outstanding engine performance that has surpassed the industry standards.

While the V12 engine is designed to overall enhance the vehicle, there are 3 commonly-reported problems with this style of engine:

  • overheating
  • hydraulic fluid leaks
  • engine misfires

Hydraulic Fluid Leak

Mercedes models experience normal wear and tear that often leads to fluid leaking from different places. Hydraulic fluid leaks are commonly reported among those who own a Mercedes with the V12 engine, but it is easy to detect this issue, as the hydraulic fluid is an amber color.

Hydraulic fluid leaks are commonly caused by damage to the seals of the active body control system, a damaged hydraulic line, or even malfunctioning struts. Routine maintenance can help to prevent or allow for early detection of these problems, so it is important to adhere to the manufacturer’s maintenance schedule to catch any problems early on.

Overheating

Engine overheating is a common V12 engine problem. It is fairly easy to detect when your engine is overheating by utilizing the temperature gauge located on the dashboard. While there are a number of reasons that an engine may overheat, the most common causes are:

  • coolant leaks
  • a worn radiator
  • worn coolant lines
  • blown head gaskets

Engine Misfires

There are several types of engine misfires, with an ignition misfire being the most common among Mercedes V12 engines. An ignition misfire is typically caused by a faulty ignition coil, failed or faulty spark plugs, or a poor connection among the wiring. While you can still drive your car while it has engine misfires, you should not let this problem go on for long, as it can cause long-term damage or result in an engine that will not start.

Reduced Fuel Efficiency

If your V12 engine is not performing as designed, you may start to notice it at the gas station. You may find that you’re filling up more often than normal even though you are not traveling greater distances. If your engine is misfiring, it can be due to too much fuel being added in ratio to air in the combustion process. This can cause more fuel to be burned than necessary.

How to help prevent V12 engine complications

Your Mercedes V12 engine requires routine maintenance which has been put into place by manufacturers for the safety and longevity of your vehicle. One of the most important things you can do for your vehicle is to regularly check the coolant and motor oil levels, ensuring the reservoirs are full at all times. These 2 fluids are vital in keeping the engine running at optimal temperatures.

In addition, be mindful of your possible bad driving habits. Driving a powerful vehicle entices drivers to want to test their vehicle’s maximum horsepower abilities. However, pushing your vehicle too hard too often can result in costly engine repairs if parts break, crack, leak, or malfunction.

Having your vehicle inspected regularly by an expert has been proven to help detect malfunctions or failing parts early. In doing so, drivers can get ahead of the problem versus drowning in repair costs. Sticking to the Mercedes maintenance plan will keep you safely on the road, driving your car with confidence. Your specific plan for your model is in your owner’s manual and also available as a downline on the Mercedes website.
