Power Train Problems of Mercedes Benz ML350 - part 2

The car was on an incline in my driveway. It has the transmission shift lever on the column, and I had been backing down the driveway. I stopped placed the car in park and got out with the engine running to move something. The car sat in place for approximately 10 seconds and then spontaneously took off at approximately 5miles/hour. Fortunately my daughter was standing on the driver side of the car in front and saw the car rolling forward, jumped in and hit the brakes just as the car struck one of other cars on the driveway. The shift lever was reading the drive position, even had I not placed the car in park, it would not have been in drive but reverse as I had been proceeding down the driveway.

Car does not down shift when slowing down to stop. Then when you try to accelerate it barely moves. One has to place the transmission into park, then turn engine off and then restart engine to reset transmission. Fault codes in the onboard computer all point to valve body conductor plate on transmission. Mercedes will not sell or replace part to independent mechanics. They will only sell it to dealers which I believe are told to diagnose a different problem. In other words work around the problem to generate income before actually trying to fix the actual problem. This is a well documented problem amongst ml 350 owners with some paying thousands and still not having the problem corrected. Please look into this because this can become a safety issue especially at a busy traffic light.

The contact owns a 2007 Mercedes Benz Ml350. The contact stated that while driving 50 mph the transmission shifted gears independently. The contact mentioned that he was able to maneuver to the shoulder and turned the engine off in order to reset the system. The vehicle was taken to the dealer. The manufacturer was made aware of the failure who did not offer any assistance since the vehicle was not included in any recalls. The failure and current mileage was 58,163.

As I was attempting a sharp left turn the car shifted from d to d1. To recover I placed the transmission in n then back to d, while moving. I continue with no further problems. This was not the first time since it has happened 3-5 times since I bought the car in June 2011 with 43,616 miles.

Around 45,000 miles the check engine light came on. I took the vehicle to a Mercedes Benz dealer service department and was notified that the balance shaft needs to be replaced. In order to replace the balance shaft, the engine needs to be taken out of the vehicle and taken apart. Estimated cost $6,000. The service dept. Told me that it was due to a part that was not hardened properly during manufacturing. There is a technical service bulletin (s-b-03. 30/08i) that was originally issued in 2007 which was found in internet searching, however it seems like Mercedes Benz knows that the check engine light (on the majority of these vehicles) will not come on until when the warranty has expired. Since this fix is a huge expense, they are not going to issue a recall even though it is clearly a safety concern. If I would've have continued to drive the vehicle in this condition, eventually the balance shaft would have continued to break its teeth resulting in engine failure. Continuing to drive the vehicle in the condition is not safe, it is a matter of time before the vehicle stops running and the engine would need to be replaced. The Mercedes Benz USA replaced our balance shaft or pay for it people who already fixed.

Mercedes benz balance shaft problem (drivetrain) on 2006 Ml350 a technical service bulletin was issued in 2007 by Mercedes Benz but owners such as myself were never notified.

With the gear selector in park and the passenger side front seat occupied, the vehicle rolled backwards from a 4. 4 percent grade and overturned as it proceeded downhill. Inspection of the transmission parking gear revealed that the parking pawl had been activated but did not engage a parking gear slot. This incident was attributed to excessive angle on the parking gear slot sides, an underpowered pressure spring in the park interlock mechanism, or a combination of both of these conditions. These conditions permitted the parking pawl to be rejected from the parking gear slots at speeds well below the park pawl engagement (target) speed of 6 kph (3. 7 mph), as defined by sae specification j2208. A series of such rejections while the driver’s seat is unoccupied poses a safety hazard by allowing the vehicle to continue to roll in an uncontrolled manner on certain slopes while the gear selector is in park. A more detailed analysis of this issue has been prepared and shared with mercedes-benz. Please contact me to obtain this analysis and the related response from mercedes-benz representatives.

Around 52,000 miles the check engine light came on. I took the vehicle to a Mercedes Benz dealer service department and was notified that the balance shaft needs to be replaced. In order to replace the balance shaft, the engine needs to be taken out of the vehicle and taken apart. Estimated cost $4,000 to $7,500. The service dept. Told me that it was due to a part that was not hardened properly during manufacturing. There is a technical service bulletin (s-b-03. 30/08i) that was originally issued in 2007, however it seems like Mercedes Benz knows that the check engine light (on the majority of these vehicles) will not come on until after 50,000 miles, when the warranty has expired. Since this fix is a huge expense, they are not going to issue a recall even though it is clearly a safety concern. If we would've have continued to drive the vehicle in this condition, eventually the balance shaft would have continued to break its teeth resulting in engine failure. Continuing to drive the vehicle in the condition is not safe, it is a matter of time before the vehicle stops running and the engine would need to be replaced. The service department replaced our balance shaft, the parts used are too numerous to list along with labor codes. Here is a brief breakdown: 28. 8 labor hours total $2,940. 48, parts $1,263. 50 (consumer cost), $925. 49 (net cost). The failure has been corrected, however the service dept. Told me all of these vehicles made during this time will eventually have this failure and it's a safety concern, not to mention a very expensive repair. I feel there should be a recall issued for these vehicles and Mercedes Benz should be required to notify consumers of this failure. I was an original purchaser and had mine repaired, however there are people out there buying these vehicles used unaware of the problem, not only stuck with a $4,000 + repair, but also unaware of the safety hazard. Mercedes benz should take responsibility.

The VIN was not available. The approximate failure mileage was 100,000 and the approximate current mileage was 115,000.

This vehicle has had nothing but problems. At around 32,000 it needed transmission repair. Unfortunately it was past the three year offered warranty. At around 45,000 miles, I was told that it needed new shocks. All of the repair men that I spoke with could not believe that this vehicle would need suspension work at such low mileage. After reading these posts, it is clearly a defect in the suspension. Meanwhile, I went through another set of tires because I am still waiting to repair the suspension. I guess I can wait no longer and will need to come out of pocket again. This vehicle has been a nightmare and based on this experience, I will never buy another mercedes.

Mercedes wants $4,000 - $6,000 to replace defect part.

2006 mercedes Ml350. Upon turning 78k miles a check engine indicator appeared. Upon examination a sprocket in the timing chain assembly was worn and in danger of failure. Within one day - and with very little effort - I found two others with the same motor having the same problem. Mercedes prides itself on excellent engineering and manufacturing and charged me $50k for such excellence. With this kind of mileage there should be no problem with this type of machinery. Apparently mb agreed. Upon working with a local dealership mb paid 50% of the bill which totaled $4200 with discounts. This item should truly be a recall and should not have cost me a penny. Mb is trying to keep this situation quiet as not to incur extensive damages. I would like to see a recall take place for others who will inevitably have this same experience at some point.
