What 2008 Mercedes-Benz CLK350 owners say
Fuel & propulsion system
Routine maintenance identified gasoline leaking from fuel tank's "fuel sender". Small crack in plastic fuel sender at point where fuel hose attached to sender allowed gasoline to accumulate over time in area surrounding sender and then travel to underside of car in an area immediately adjacent to exhaust system. At time leak was discovered approx 1/4 cup of fuel had accumulated. Had problem not been discovered a car fire was inevitable
Purchased from private individual with mileage 43,000. Filled up the gas tank on two occasions. After each occasion, placed car in garage afterward and closed garage door. The smell of raw gas was overwhelming as soon as garage door was shut. Due to the overwhelming smell and safety concern, car was parked in driveway. No leaks on garage floor were found. Car parked in garage the next day without the smell of raw gas.
Electrical system
On 12/31/2017 my car was parked on drive way of 800 villa florence dr. Naples florida and without any prior sign of trouble car cut in fire from left side of trunk. There was nothing in trunk of this car except to light weight beach chairs.
My wife told me her headlight was burned out. When I replaced the bulb, I found the insulation on the electrical harness and headlights is deteriorating leaving exposed bare wires causing electrical shorting, equipment failures, electrical fires, leading to potentially serious life threatening accidents. Mercedes Benz is not supplying a fix as reported by multiple owners. Also extended warranty insurers are denying coverage due to the wide spread defect across the Mercedes Benz models.
Air bags
Takata recall. SRS light came on. Took car to dealership. Advised that airbag in passenger seat had high resistance.the seat back was removed and airbag replaced. Approximately 3 weeks later and $981.00 my car was returned to me.
