But I was able to break ansdstop . Sometimes it started back on and sometimes it did not.dealer replaced the crankshaft sensor and the sender unit. Had to pay the bill of $600 plus towing. They did not inspect other safety issues like the sbc pump or let me know about the 10 year warranty. Neither did they tell me if sbc pump failure or its malfunction has any impact on other parts of the car. …”

“While traveling north on I-5, at approx. 65 MPH, display showed red lettering vehicle too low stop car . Made my way over to side of road when message disappeared. Proceeded with trip. After a couple of miles, message appeared again. No significant difference in car handling or performance felt. Message again, disappeared. This continued until arrival at home. Thought faulty relay or some electrical problem. Once home, I got out of car and heard a sound as if air was escaping from a balloon. Noticed left front had dropped almost on tire. Car not drivable. Towed to shop. Bladder burst.”

“I own a Mercedes-Benz E500 bought new in 2004. 3 days ago I was driving the vehicle at about 35 miles an hour and car stalled and came to an abrupt stop in the middle of the road with no warning. I could not start the engine back for about 5 minutes. Luckily there were no other vehicles behind me, which would have hit me from behind. I later towed the car to the mercedes service station. They reported it as an electircal failure due to failing of the crankshaft position sensor. They have replaced the faulty sensor and the car is running ok now. …”
