When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

EXTERIOR LIGHTING
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

AIR BAGS
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.

STRUCTURE:BODY
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.

MY CAR IS A 2006 MERCEDES BENZ SLK280. THE SRS LIGHT INDICATOR TURNED ON AND STAYED ON.. THE GARAGE SAID THE COST OF REPAIR OF THE SRS SYSTEM WOULD BE OVER $400.00. I DO NOT KNOW IF THE RESTRAINT SYSTEM / AIRBAG WILL WORK IF THERE IS AN ACCIDENT, IT MAY BE A VERY HAZARDOUS CONDITION IF THE MERCEDES IMPACT PROTECTION SYSTEM IS NOT WORKING.

I OWN A 2006 MERCEDES SLK280 AND MY SRS LIGHT CAME ON ABOUT A MONTH AGO. SINCE MY ORIGINAL WARRANTY EXPIRED IN JUNE, I HAD PURCHASED A NEW ONE FOR CLOSE TO $2,500 FOR A NEW 4YR/40,000 MILES. I LOOKED UP ON GOOGLE TO SEE IF THIS IS A COMMON PROBLEM AND FOUND A NUMBER OF SIMILAR PROBLEMS. I AM SURE THERE ARE A LOT MORE AS I DID NOT EVEN POST ONE. SEEING THAT THE SRS IS THE AIR BAG DEPLOYMENT AND A SAFETY ISSUE, I FIGURED THIS WOULD BE COVERED UNDER THE WARRANTY. I WAS SURPRISED THAT FOR SUCH A HUGE SAFETY ISSUE, MERCEDES DID NOT REPLACE THE DEFECTIVE PART. THE TOTAL CAME TO $446.37. I AM MORE CONCERNED ABOUT THE SAFETY ISSUE AND I WONDER HOW MANY OF THESE GO UNREPORTED.
