The car started having a coolant problem at 40,000 miles. The Mercedes-Benz dealership I lived near did not immediately fix the problem, saying it was normal for their cars to run at very high temperatures. A few days after going to their service center, steam started coming out from under the hood. I took it back to them, and they replaced the radiator.
At 42,000 miles, a beeping sound would go off in the cabin whenever the roof separator canvas in the trunk was displaced. Simply hitting a bump would cause this. The dealership was never able to fix the problem. However, pushing the retractable roof button slightly would stop the beeping sound.
At 45,000 miles the passenger side door would not close properly. One would have to slam it to get it to close. I never got this problem fixed.
At 47,000 miles, the retractable roof would not go down when prompted to do so. I brought it to the Mercedes-Benz dealership, but it started to work again before they even took a look at it. When I got home, it stopped working. This was quite frustrating, so I asked them to replaced the wiring that controls the rectractable top.
The driver side brake light started having problems at 50,000 miles. Initially, the bulb was replaced, but the problem persisted. A week after the bulb was replaced, some electrical wires needed to be replaced.
The starter was replaced at 52,000 miles.
The driver side headlight bulb was replaced at 58,000.
The spark plugs were replaced at 63,000 miles.
The interior cabin light was replaced at 70,000 miles.
