I was driving my car and it suddenly turned off on me. I tried to start it again but it would crank but not turn on. I had a lil less than half a tank of gas but there was no gas being delivered to the engine. After inspecting the fuel sending unit I notised that the plastic around the wire connector pins was a bit melted and there was a small hole that went straight trough the sending unit cover. I replaced the sending unit but the melting still continues. It seems like the wire gets too hot and the plastic melts around the pins. Im afraid this can even cause a fire since all the fuel is just inches bellow it.

What 2003 Mercedes-Benz AMG C32 owners say
Most recent owner complaints, unedited.
Fuel is leaking from the sending unit of the vehicle and down onto the rear wheels differential, the vehicles fuel tank and sender unit had been replaced by mercedes under warranty on 11/25/03 mileage in 43088 mileage out 43092 at the hoehn carlsbad ca dealer ship: invoice number 465553. This has now happened again and I have found that this issue is not a limited issue to my vehicle but one that has impacted all c class and e class vehicles and has an estimated repair cost of $2,073.30. How is daimler ag allowed to sell these vehicles that pose an extreme rick the public and property in the us. I have been told my vehicle is now no longer covered under any warranty and I will have to foot the bill to repair this obvious design floor and subsequent malfunction that posses a life threatening risk to me and my family if not resolved asap. I dread to think about all the present mercedes c-class and e-class owners driving around in a ticking time bomb just waiting to go off, there must be hundreds of thousands of vehicles that have defective fuel sending units/gas tanks leaking gas down and around hot exhaust pipes of their vehicles and they are not aware of this perennially life threatening malfunction because daimler ag has not recalled all vehicles outfitted with recognized defective fuel sending units/gas tanks and resolved the ticking time bombs. It's obvious to me whatever attempt daimler ag has taken is not enough to mitigate any further defective fuel sending units/gas tanks. Please advise on any whether we have any re-cause with daimler ag or mercedes u.s.a to get this frightening issue resolved for not only me but also the hundreds of thousands of american motorist presently driving ticking bombs. You may contact me on daytime phone number to discuss this issue. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
The fuel tank on my 2003 c32 leaked. The symptom was a strong gas odor inside the vehicle. Upon further inspection, there was fuel leaking from under the vehicle. I took it to the mechanic, and he diagnosed it as a leaking fuel tank. When he removed it, he showed it to me and I saw the part that was cracked, which was below the rear seat of the car. There appears to be a widely known malfunction with fuel tanks for mercedes. This was a very stressful event, especially with fuel leaking outside the car and not knowing what could happen (fire risk, etc).
