I am absolutely livid with Mercedes! My 2022 Mercedes C200 4Matic has left me stranded twice due to recurring spark plug problems. The first time, thankfully, I was in the city and managed to limp to a service center. But the second time, on my way back from a holiday, just outside Ankara near Kızılcahamam, my car started sputtering, the yellow engine light flashed, and it completely lost power despite me pressing the gas. I barely managed to pull over to the emergency lane.
The most infuriating part is that my car's spark plugs were just replaced during its 45,000 km service. Mercedes roadside assistance confirmed two faulty spark plugs and replaced only those two under warranty, telling me to have the other two replaced at my next service. This whole ordeal took three agonizing hours on the side of the road. What's worse, two friends with the exact same car have experienced this identical problem, clearly indicating a chronic issue with the spark plugs Mercedes is using.
Today, during my 60,000 km service, I explained the entire situation to the authorized service center, Batı Oto Mercedes. Despite roadside assistance explicitly recommending replacing the other two spark plugs, they refused to do the necessary replacement. This kind of negligence and shoddy part quality is completely unacceptable for a company as prominent as Mercedes. Frankly, I'm so disgusted that my next car will likely not be a Mercedes. You need to address this widespread spark plug defect immediately!
I am absolutely outraged with Mercedes-Benz and their authorized service centers! My 2023 Mercedes-Benz, still under warranty, is experiencing severe vibration and shaking in first and second gears. This is a brand-new car, and it's practically undrivable. I first went to Gülsoy Otomotiv in Florya,...
In September 2023, I purchased a brand new C200 from Tuzla Gülsoy Otomotiv. With only 5500 km on the odometer, on May 18, 2024, it broke down due to a 48-volt battery error. Roadside assistance got it started, but on May 19, 2024, the engine malfunction light came on. After taking it to the service ...
On September 29, 2025, my Mercedes C200 completely discharged its battery before it was even fully charged, leaving me unable to start the vehicle. Despite making numerous calls to roadside assistance for help with my car, which remains under warranty until February 2026, I received no response. I h...
My 2020 model Mercedes A 180 D vehicle constantly gives engine failure due to the spark plug. Even though I went to the service for the same error 4 times in total, it was reported that the spark plug was replaced and the problem was gone. Even though 10 days have passed since the last change, my ve...
The check engine light on my 2020 Mercedes A 180d turned on. Turns out, the problem was a busted cable for the heating spark plug. Just 11 months ago, the identical part was replaced under warranty at Kurtköy G***** Mercedes. Now, in under a year, the same problem has come up again. Even though I as...
