Top Five Issues That Tend to Plague Mercedes-Benz Vehicles

When discussing the top luxury car brands, Mercedes-Benz vehicle is always in the conversation. Its vehicles have a reputation offering an amazing blend performance and comfort. While these German-engineered automobiles are built to last, owners must put a big priority on maintenance. Some repairs will ultimately need to be made. Here’s a look at the top five issues that tend to plague Mercedes-Benz vehicles.

1. Worn Engine and Transmission Mounts
Engine and transmission mounts are more important than you think. These components help ensure a smooth driving experience by balancing energy absorption. When the mounts start to go bad, you will begin to notice increased engine noise and more vibrations while on the road.

Although you can drive a vehicle with worn mounts, it’s best to have them replaced as soon as possible. Over time, the excessive shaking can cause certain parts to become damaged. After a mechanic makes the necessary repairs, your car will be far more pleasant to drive.

2. Bad Crankshaft Sensor
When their vehicle won’t start, many drivers immediately fear a dead battery. However, there are several more things that can cause this problem. Mercedes-Benz vehicle crankshaft sensors are especially prone to failing. Other symptoms of a worn crank position sensor include poor throttle response, stalling, and decreased fuel economy.

To find accurately pinpoint the problem, an auto repair technician will need to perform a diagnostic test. If your vehicle is deemed to have a bad crankshaft sensor, the only option is to have this electronic device replaced. Fortunately, crank position sensors are relatively inexpensive.

3. Engine Misfire
It’s hard to ignore a misfiring engine. Not only will your Mercedes-Benz vehicle begin to run roughly, but it will also struggle to get up to speed. Furthermore, the check engine light is likely to turn on.

In many instances, this issue stems from a set of worn-out spark plugs. In order for the engine to maintain the proper air-fuel mixture, the spark plugs must be firing correctly at all times. While it’s generally recommended to have these parts replaced every 30,000 miles, many Mercedes-Benz owners neglect doing so.

4. Bad Control Arm Bushings
If your Mercedes-Benz vehicle is approaching 100,000 miles, its control arm bushings may go bad. Found in the front suspension, these rubber components are designed to limit the amount of vibration created between the vehicle’s frame and the wheels. Worn control arm bushings can cause quite a few problems, including a bumpy ride and accelerated tire wear. Your car will also be more difficult to steer.

It’s a good idea to have all the control arm bushings replaced at the same time. When one fails, the other is soon to follow.

5. Not Going Into Gear
Don’t panic if your transmission suddenly doesn’t go into gear or experiences shifting issues. Mercedes-Benz automatic gearboxes are typically quite durable. However, the transmission’s valve body and 13-pin connector are not the best.

The good news is that these parts are not a big challenge to replace. Before buying a pre-owned Mercedes-Benz vehicle, be sure to get a pre-purchase inspection. An experienced mechanic in Asheville will quickly recognize the red flags of a faulty transmission.
