Five of the Most Common Mercedes Repair Issues
Continue reading for a rundown of five of the most common Mercedes repair issues.
1. Engine and Transmission
On older Mercedes-Benz cars, the engine and transmission mounts were solid rubber. Their job is to keep the engine and transmission stable while also preventing vibrations from reaching the passengers. The rubber mounts, on the other hand, tend to fail after a while and send you a signal every time you apply the gas.
Newer models have liquid-filled mounts that are less prone to failure than rubber mounts. The ones that are failing will give you warnings in the form of a growing vibration in the steering wheel and passenger cabin. To avoid Mercedes mount problems, you should have them diagnosed every 80,000 miles or seven years, whichever comes first.
2. Starter and Ignition
Mercedes vehicle starting issues cause the engine to crank but not start. The crankshaft position sensor is to blame, as it fails to send the engine the TDC signal.
The ignition coils and spark plugs should be replaced every 100,000 miles, according to the manufacturer's recommendations. These things, on the other hand, can show troubling signs prior to that time.
3. Steering and Suspension
After 60,000 miles, some specific components such as control arm bushings, tie rods, sway bar links, and ball joints begin to fail. These parts are responsible for keeping your suspension components in good working order. So, if you notice any misalignment with the steering wheel or steering, get your Mercedes to a professional repair mechanic before the entire suspension system fails.
4. Oil Leaks
After 1995, every Mercedes-Benz model had an electronic transmission system. While it is a fantastic system and innovation for Mercedes vehicles, one common issue is that the electronic transmission system frequently causes graphite build-up due to an oil leak.
An oil leak in a Mercedes-Benz can occur in the same way that oil leaks in other cars do, but because of the electronic transmission system's fragility, an oil leak in a Mercedes presents a much more concerning situation. It's likely that the oil pressure switch is leaking if you start to notice small issues like a constant check engine light or O2 sensor failure.
5. Catalytic Converter
Mercedes vehicle catalytic converters have been known to wear out after only 60,000 miles of use, resulting in a slew of new problems, including engine misfires and hesitations. Luckily, if your catalytic converter has failed, your check engine light will illuminate, providing you adequate time to get your vehicle to a repair shop.
