If You Do Not Know These Mercedes Problems Now, You Will Hate Yourself Later!
Mercedes-Benz is a brand that you can absolutely trust when it comes to a combination of luxury and performance. Driving a dashing, brand new Mercedes-Benz is a pure pleasure. But, the cars can develop some hitches over time with or without regular upkeep and repairs. Facing such issues is frustrating considering the brand’s worldwide reputation. However, you will know what to expect if you are aware of the Mercedes problems.
Common Mercedes Problems to be Aware of
As the owner of a Mercedes-Benz, knowing about the Mercedes problems that tend to occur in older vehicles will help you to be prepared and make the right maintenance decision.
1. Engine and Transmission Mounts
The engine and transmission mounts on older Mercedes-Benz cars were made of solid rubber. Their purposes are to keep the engine and transmission stable and prevent vibration being felt in the passenger area. But, the rubber mounts tend to fail after some time and send you a signal through a huge kick every time you apply the gas.
The mounts in newer models are filled with a liquid and they don’t fail as easily as the rubber mounts. The failing ones will warn you via an ever-growing vibration in the steering wheel and passenger cabin. To prevent the Mercedes problems of mounts, you should diagnose them regularly after 80,000 mileage or 7 years.
2. Mercedes Won’t Start
The Mercedes starting problems will make the engine crank but refuse to start. The crankshaft position sensor is the culprit here that does not send the TDC (Top Dead Center for the piston in the number one cylinder) signal to the engine. As a result, the engine does not fire despite cranking. The sensor failure is followed by gradually prolonged cranking times.
3. Gear Shifter Does not Shift from Park
It’s a problem exclusive to the Mercedes-Benz E and S class models. The engine will start and the car run, but the shifter gets stuck to the Park position. The failure of the selector module is behind this issue and the warning sign includes having difficulty in moving the gear from the Park mode.
4. Troubles with Misfires and Ignition System
According to the manufacturer’s recommendation, you need to change the ignition coils and spark plugs after every 100,000 miles. But, these things can show troubling signs before that period.
The ignition misfiring indicates some problems with the engine while the engine misfiring is something that you need to take care immediately.

5. Steering & Suspension Components
Some specific components including control arm bushings, tie rods, sway bar links, and ball joints start developing problems after 60,000 miles or 5 years. These parts work for keeping your suspension components alive. So, if you detect any misalignment with the wheel or steering, take the car to a service shop before the whole suspension system collapses.
6. V12 Runnability Troubles
Some Mercedes cars show a runnability issue, especially the ones with the V12 engine. Symptoms of this problem include a check engine light, cylinder misfires, and failure of O2 sensors. The culprit is likely to be leakage of oil from the oil pressure switch. Changing it will solve these Mercedes problems.
