What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Headlight wires (Inside Housing) are frayed / melted. Can cause fire. I was replacing my bulb when I noticed the wires in the plug were completely stripped with no shielding. I traced it back to the connector and the wire shields were either frayed or completely gone
Front lowbeam headlight warning light on. Mechanic changed headlight bulb but it still did not work. After about a week the warning indicator went off and headlight worked. A few days went by and the indicator came on again. The low beam did not work.
Trunk failure. The trunk, when open, may suddenly fall very fast at any time. When you open the trunk it stays open but without warning may suddenly drop hitting you in the head. The trunk is actually quit heavy and can cause serious trauma to a person or damage to the vehicle as it slams down with force.
The rear marker lights are going on and off for the last few months, now they are off for good. The wires to the lights look fine, the bulbs look fine. I have even replaced the bulbs but they still dont work on one side. Earlier models are having same issue as this model. This car is unsafe.

Tl* the contact owns a 2006 mercedes-benz slk280. While driving 60 mph, the contact noticed strong fuel odors in the vehicle. The failure occurred randomly. The vehicle was taken to an independent mechanic, but the cause of the failure was not determined. The vehicle was not repaired.
Srs light went on and stayed on. Dealer says driver restraint system failed. Repair would cost $700.00. This is a critical safety issue and this model car should be recalled for repair by dealer at mercedes benz cost, as this is a common failure on this model and likely a defect.
While driving on a 50 mph expressway, my car suddenly went into a low gear, rev'ing very high. I had to decelerate quickly and I was unable to speed up to keep up with the flow of traffic. The dealer said a conductor plate had to be replaced. But this is a real safety issue.
