What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2006 Mercedes-Benz SLK280, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
Electrical system faulty. 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. This time the left side marker lamp indicator came on and the bulb wasn't working. Before I could take it in for repair the side marker was working again. It goes off and on about every other month. Also, the indicator for one of the bulbs above my license plate goes on and off, but it says bulb malfunction. Now joining is the passenger side ABS light. Sometimes when I start the car the warning indicator on the instrument panel is illuminated but then goes off after I start the car several times, about a day or two. I never know which electrical component may not be working when I turn on the ignition switch. Sometimes no warning indicators will be displayed. The side marker lamp indicator hasn't been on in months, but 3 days ago it came on again and both low beam lamp indicators are on as well. So, right now I'm driving with my high beams on. I'm just waiting for them to work again, you never know. It's so frustrating and dangerous. I have read that this is a common issue. It needs to be looked in to.
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.

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
