Problems You Can Expect in Mercedes with a V12 Engine

Mercedes-Benz SLS Roadster Engine

If you drive a Mercedes, then you’re familiar with one of the most highly-desired vehicles on the market. Luxurious, powerful, and elegant, these cars are known for their universal appeal. Depending on what you’re in to, Mercedes vehicles offer a wide range of options, from more economical and practical to complete powerhouses of endurance and agility. If you drive a Mercedes-Benz with a V12 engine, then you’re likely enjoying the latter qualities in your car.

Mercedes vehicles with V12 engines are equipped with tons of power, and they definitely deliver in horsepower. Recent models that fall under the Mercedes-Benz S-Class offer their client base more than a simply practical, economical driving experience—in fact, they push vehicle performance standards to their highest. While these machines are naturally impressive, they can still run into their fair share of issues. Actually, Mercedes V12 engines’ issues are unique to these vehicles, and it’s important to keep some of these in mind in case you encounter them yourself. Here are some problems that you might expect and prepare for in your Mercedes V12 engine:

Leaking Hydraulic Fluid

Leaking fluid under any circumstance isn’t usually good, but it does serve an important function in visually warning the driver that it might not be safe or reliable to drive the car. If you notice any fluid leaks, it’s best not to drive the car and to take it to your most trusted Mercedes specialist. However, it’s important to know how to differentiate between the various fluids in your car before assuming the worst. The active body control system is known to leak in these V12 engines, and the leak may originate due to an issue with any number of the components of the system, including seals, hydraulic lines, and struts. Hydraulic fluid is generally an amber color.

Premature Brake Wear

So, you’ve been driving your new V12 engine Mercedes S-Class for only a year, and your brakes are showing signs of wear. This would be concerning for any driver, let alone someone driving a brand new Mercedes! One of the unfortunate problems that are common among these model vehicles is premature brake wear, and it usually begins with squeaky brakes. What happens is the brake pads wear quickly, and often unevenly due to the type of brake pads that come stock in these cars. When the pads wear quickly, the rotors also begin to wear. This is problematic because rotors can be expensive to replace. This is a concerning symptom in a new car, and can be especially dangerous if it goes unattended to. At the first sign of brake wear, bring your car to an automotive specialist for an inspection.

Engine Misfiring

Engine issues are rare, and particularly disheartening to those who invest in such high-quality cars as Mercedes. Since you likely decided that a Mercedes was a reliable, trustworthy option in a new car, when you encounter engine misfiring or rough running you might be immediately disappointed in your purchase. Usually engine misfiring in V12 Mercedes engines is due to a problem with the ignition system, and can usually be traced back to problems with ignition coils. Having a professional perform a differential diagnosis to find the source of the problem is critical, as your Mercedes will be unreliable until the problem is fixed.

What you can do to prevent common problems from arising

These are only some of the common issues that Mercedes V12 vehicles encounter, but they’re all important to be aware of. The most important thing you can do to prevent these issues from occurring is to stay on top of routine maintenance procedures and consult with your automotive specialist to schedule tune-ups and regular inspections.
