Filed Jan 29, 2026 · Engine, Fuel system · GA

fuel lines/ clamps defective causing a fuel leak. vehicle could catch on fire and fumes are extremely strong inside the cabin. issue confirmed by Mercedes dealer, mentioned there is an extended warranty up to 120,000 miles. rejected mine because i was at 120,300 miles. had to pay out of pocket. no warning lights or anything just the really strong smell of fuel and fuel range dropping. this is a very common issue thats known and should be a recall.

During cold weather there is always a gasoline smell when starting the engine that eventually goes away. On 01/20/2025 the smell was so intense that I decided to stop the engine and leave the car outside the garage just in case. Upon opening the hood, I noticed an amount of a type of liquid similar to gasoline right on the undercarriage protector covers. I could not reach with my hands but instead I used a wood stick that I had in the garage. I reached the liquid and submerged the stick for like 10 seconds and pulled it out. When I smelled it, it indeed smelled like gasoline. I took the stick to the back patio and lighted it up and as I suspected, the tip of the stick lighted up like a torch. I called a nearby mechanic and made an appointment to check it out and today (01/23/2025) I am bringing it in. I went to Youtube and found numerous videos showing this "well known issue" with some of the fuel lines in this type of vehicle which I believe is a tremendous hazard. Just imagine that when I turned the engine up on 01/20/25 the engine could had gone up in flames burning not only the vehicle, but my entire house with maybe my family inside? Please take serious note on this issue and try to come up with a mandatory solution for the problem. I will let you guys know the findings from the Mercedes mechanic once the job if completed in case you need more information. Thanks

On oct 14th at night car was driven in heavy rain off interstate i5 off ramp to exit interstate. There were cars both in front and behind us exiting and upon driving further noticed there was standing water. Other cars were making it through slowly, there was no room to turn around. This car almost made it to the end of the offramp and then stallled. Other cars were forced to go around. Tried to restart the car to no avail. Called for roadside assistance. Noticed smoke coming from the hood and then all lighting went dark in car. Then saw flames from the hood. Quickly ran through water to escape and flames got several feet high. Passer by's had called 911 as entire front of car was engulfed in flames. Fire department had to cut open car hood to put out fire. Car damaged beyond repair and they too were incredulous that a new car would be engulfed in flames after stalling in the rain.
