What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The air bags failed to deploy and the contact sustained chest injuries from the seat belt. The vehicle sustained severe damage to the front end and was towed to a collision center for repairs. A police report was not filed of the incident. The manufacturer was notified of the problem.
I am the owner of a 2007 Mercedes-Benz SLK280 with VIN: [XXX]. My vehicle was part of the Takata airbag recall, but the airbags were never replaced. Currently, the NHTSA recall status for my VIN shows "no active recalls," even though the repair was not completed. This creates a serious safety risk.
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.

What to check before buying

- Powertrain. Shift quality under load, harsh shifts, transmission codes, CV joints.
- Engine and cooling. Radiator and fan after a frontal hit, coolant level and condition, overheating.
