I was driving eastbound in the number 1 lane of california highway 24 about 1/4 mile before the tunnel road exit. I heard a noise coming from the engine are of the car, looked at the instrument cluster and noticed that the engine light had illuminated, and experience a sudden loss of power. I pulled off of the highway at the tunnel road exit and stalled on the off ramp. I attempted to restart the engine twice by turning the key. I saw smoke in my rearview mirror, exited the vehicle, and saw flames coming from underneath the vehicle. I called 911 and gave the dispatch operator my location. By the time the highway patrol and local fire department arrived, my car was totaled. The attached photos tell the story of the damage.
Was driving on the highway when suddenly over heat and check engine light came on, and about 20 seconds later the car loss all power. I almost got hit my the car behind me, but was able to safely pull over to the side of the highway.
Engine light flashed briefly and went off. Within one mile engine lost all power. As I slowed to a stop, a large cloud of steam erupted. Car was in shop for over a month and most of the engine was replaced. No explanation of lack of warning lamps. A second two week trip to the dealer was needed to resolve all the issues. Car still has engine light on
While driving at a steady speed of 40mph, the vehicle suddenly lost power. You could hear that the cylinders and pistons stopped working. The vehicle had 2 gallons of gas. We put in 2 more gallons at the adjacent gas station and limped home at 30mph. The dealership picked up the vehicle at our home and drove it from milwaukee to chicago without incident. The dealership said they replaced the purge valve and all 3 ignition coils;come and pick it up. On our drive home, going a steady uninterrupted 40 MPH (no stop signs, or stop lights at all) we drove 28 miles and the same problem happened again. The vehicle was towed to the dealership. The dealership requested assistance from mercedes. Mercedes declined, stating they would accept the problem when the dealership identified the source of the problem. After 10 days the dealership notified us that they could not identify the source of the problem. We waited through the 30 business day lemon law period and filed for relief.
While driving at night at about 45 miles per hour, I was shifting into fifth gear and the car just went blank. The lights went out and all noise ceased to exist. At first it was a bit of a shock, so I immediately pulled off of the road onto the dirt. Luckily there were no cars around as the sudden lose of power could have caused someone to run into me, as I had no lights. After looking around the insde of the car I noticed that the key was in the off position. The key on this car is in the middle console, right next to the gear shift selector. I determined that upon shifting my jacket sleeve had brushed against the key, and becuase the key is so easy to turn off from the on position, the key just turned off while driving. This was the first occurrance of this, as it happend one more time. I have had to remember not to leave my hand down by the shift lever, in fear of turning off the key without knowing it.
I was making a left turn when. All of a sudden I lost power and the car shut off in the middle of the intersection. I had to coast over to the right lane, stop and turn the car on in the right lane.
