Crankshaft Position Sensor Problems of Mercedes Benz E320

Bought used one owner car w/88,500 miles in July 2015. After driving only 200 miles check engine light came on, engine would turn over but not start, it was towed to repair shop. Codes read crankshaft sensor, generator. Mechanic replaced crankshaft sensor and repaired wire to it. Did not replace alternator. Called and advised car was ready for pickup. Picked up car and drove less than 2 miles and check engine light came on again. Took back to mechanic who removed codes. Drove another 5 miles and check engine light came on again. He didn't answer phone, drove home in limp mode where it sat for over a month when another mechanic was willing to tackle job. He put on new alternator and drive belt. Crankshaft sensor was bad again and he replaced it. Car would not start. Towed to mb in franklin, TN who said ecm/ ecu module bad. Replaced it and then said batteries bad, and alternator bad. They replaced batteries but local mechanic told them alternator was working fine when it was put in car. Car towed back to local mechanic who checked and said alternator was indeed bad now and he replaced it with one he checked out again before installing. Now the alternator was not being allowed to charge the system and is being towed back to mb in franklin, TN. After searching the internet I found that mb has been installing defective wiring harnesses in their cars since the 1990's and they know it but will only replace the defective harness to those to yell the loudest because there are supposedly millions on cars on the road just waiting to short out expensive parts and cause owners costly repairs. I am yelling at the top of my voice for you to go after them with a vengeance and make them do the repairs. I have spent over $4000. Already on this car which should have been fixed by them at their expense. The covering on the wires gets brittle and shorts out various. .

Vehicle engine suddenly and without warning stopped running while being driven. This could have caused a serious or fatal accident if it had occurred on a major highway. Mercedes benz of west chester replaced the crankshaft position sensor. The occurrence was stored in vehicle electronics. The fault was an electrical short in the crankshaft position sensor. Mercedes determined the crankshaft sensor gets hot when engine running and causes internal resistance to rise to the point of shorting out. Mercedes benz stated that a failure of this part should not have shut the vehicle off completely but rather should have resulted in the vehicle not being able to be restarted once it was stopped in ordinary operation. This is very dangerous!.

While traveling on the washington DC beltway in the fast lane, in heavy traffic, the engine completely shut down leaving us stranded in very heavy traffic. Needless to say, this was a very precarious position. Fortunately, police assistance arrived and called a towing service and got us out of harm's way. The problem was diagnosed as a failed crank shaft position sensor. This results in the computer turning off the ignition creating an obviously hazardous situation. I reported this to mercedes customer service, but they're reaction was that this occurs infrequently, but they were aware that it does happen. So I am notifying you for your information.

While traveling in the far left lane on a four lane highway the engine on the car stops in addition to the check engine light coming on. I could not move to the left shoulder because it was an additional lane for high occupancy vehicles which was also barricaded. I immediately placed on my flashers and commenced to change lanes to get off of the highway. Where this also occurred was where an on-ramp connects which added on another obstacle in an attempt to get off of the highway. It was very fortunate and lucky that no accident occurred as in the dallas area during rush hour it is very hard to just change to one lane with a running car let alone changing lanes 3 times plus dealing with merging traffic from an on-ramp with a car that is not running. After having the car towed to the dealer, the crank shaft sensor was found to be the defect. It is clearly a safety flaw by the vehicle manufacturer to completely stop an engine when a defect occurs on a sensor. In this condition the vehicle should only turn on the check engine light instead of turning the car off to place the operator into a potential deadly situation.

The car stalled while driving approx. 35 mph, this was the 4th time it stalled, the 3 other times car was not going as fast. One at a stop sign, the other 2 at about 20 mph. When car cooled off was able to start it. The 4th time could not restart, towed to mechanic found to be cps (crankshaft position sensor. Researched online found numerous complaints. An obvious problem! a dangerous problem!.

Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) September 12, 1998 I purchased a 1999 E320w. ] I am the only owner of the car. The car is driven leisurely. To date, it only has 92,000 miles on it. I have been regularly obtaining the a & b maintenance services. The electrical system has been malfunctioning for months and mb allegedly can't diagnose it; and I have been using an excessive amount of oil. A second opinion mechanic said it is oil slugging which was recalled but mb won't honor. He also said my engine / motor now needs to be replaced. There is also an intermittent scraping on the passenger side. During all of the services to mb they never told me about the recall nor provided service to ensure that my car was not affected. They said it was not a total recall but a case-by-case situation and I am not eligible. I am very fearful when I am driving. Each time I go out I fear what might happen. I do not have the funds to pay for a engine. Please help me. I can provide a timeline of the history of my vehicle which with hindsight looks like I purchased a lemon. The second opinion mechanic informed me of the recall/class action but mb concealed the information. The locks were inoperable and the key would not come out of the ignition, the check engine light illuminated, the serpentine belt, ball joints, tie rod ends were all replaced. The fuel sensor level was replaced. There was a shimmy in the suspension. The dealer replaced the tires and left rim. The valve stem was leaking, the left rear window was inoperable. The crankshaft position sensor was replaced. All of the dashboard lights intermittently, but regularly turn into line bars. The tail light circuit board and the right rear tail lamp, right front head light and left front parking bulbs were had to be replaced updated ivoq 05/27/10.

Crank position sensor (cps) started to fail when the outside temperature was above 95f. Car (1999 Mercedes Benz E320) failed to start twice when parked after driving for a short distance. Only after cooling it would start again. At one point the engine became very erratic while in traffic. At another point I was stopped on the traffic light and the engine just stopped running. Fortunately I was near home and after waiting a few minutes it started again. It was embarrassing to say the least , having a mb car stall in front of other much cheaper cars on the traffic light. Fortunately, I was using this car for only short trips and did not incur the risk of having it stall on a highway, but I am sure it would as long as the engine temperature was above a certain point. .
