general problems of the 2006 Mercedes Benz ML350

My car was included in the balance right shaft recall as 2nd owner I was just made aware as a result my check engine light came on. It was also learned that the car was included in faulty “balance shaft”. I should be included because my car has same diagnosis as defective equipment.

I encountered a major issue with the mercedes Ml350, while doing a 3 point turn in a busy suburban toronto street. The electronic shift module left me stuck in road way. Causing traffic back up and could not move vehicle. Neither forward or reverse. Tried pushing and different tactics to move vehicle off road. Had to call caa-aaa. It was a caos situation,first tow truck could not load vehicle,all wheels were locked in drive and would not shift. Had to wait for special tow have all four wheels lifted off onto dolly. Tow truck driver said it is a common problem. With mb,BMW and Audi. Vehicles towed to dealer sat at dealer. Parts on back order and not available for repair. Since was in toronto away from home. Had to source original equipment supplier to purchase part. Dealer and factory mercedes could not source part. Back ordered. The dealer agreed to install the factory oem part they could not source. My concern to all owners including myself in line traffic a basic traffic maneuver stuck in blocking traffic. Cannot moving vehicle jammed in gear that controlled by a shift module. No safe limp mode or emergency shift to neutral to move vehicle safely.

Brakes feel spongy,, when letting off accelerate feels as if transmission has a brake applied.

While driving at most any speed,transmission periodically goes into no gear or a single gear (low or a higher gear) and 'limp mode' without warning. . . . Sometimes a "check engine" light. Very scary especially in traffic on the freeway. Bought the vehicle earlier this year with 60,000 miles on it. . . I am 72 and wife is 71. . . She is afraid to drive it because of the uncertainty of the drive train. I finally took it to Mercedes Benz as the would not sell my my independent mechanic the parts to repair problem. Mercedes says that I need to have the 722. 9 transmission valve body replaced at $3,000 period. I have read of a myriad of similar problems with other owners of cars with this type of transmission. . . . Even class action suits. I believe that this is a very dangerous condition that must be resolved and repaired by the manufacturer. I even called Mercedes Benz of north America and their representative said he knew of no problems with this model of transmission. I also read that they are not changing any parts. . . . Just reprogramming the transmission to not go into limp mode and not activating the check engine light. . . . . How can I insure that my vehicle will be repaired correctly and be safe to drive?.

My car suddenly lost power in the highway, and didn't want to accelerate,causing car to high rpm rev,going into limp mode and not accelerate, almost causing my family and to have a serious accident. Vehicle was diagnosed by a shop which stated my speed sensor conductor plate is defective. . . Upon doing research, I have noticed that this is common dangerous issue on the 06 mercedes ml models. . Mercedes even has a class action suite against them due to this issue. .

My 2006 merc Ml350, broke down on me 10/22/16, as soon as I got off the freeway because I was hearing a crackling sound from the engine. I was able to drive in a local parking lot to avoid embarrassment. This vehicle is always needing something, and at this time it was hard to turn the sterring wheel to park it because the serpentine (vbelt) had unraveled its way from the alternator pulley!! the lord had saved my life! same year in March fremont dealership said I needed to replace my air condersor but never said anything about my belt being worn or cracked or anything about this. This should have been noticed at that present time. They misinformed me at that time about the vbelt needing to be replaced and tried to sell me a air mass sensor. Mercedes knows about vehicle 2006 year and all the parts that are malfunctioning and wont lift a finger to recal or reimburse or pay entirely. I vould have died on tge freeway had this v belt wouls have came off! tookbitvin for repairs and the dealer is requesting $2350 to replace air condition unit and they will have to open up alternator & adjust + vbelt. Campaign anyone or botcott mbusa!!.

Check engine light came on, and got both codes p0016 and p0017. Upon further investigation, this seems to be a known defect by Mercedes Benz for the balancer shaft worn sprocket issue. This is an expensive repair, almost the cost of the vehicle! mbusa picks and chooses who they will help? wow, wish I never got this car!.

My 2006 Ml350 (automatic) has a transmission problem where shifting down causes the vehicle to lunge forward. All gear shifts (up or down) are hard and can be felt by the occupants in the car in the form of a jerky motion. Scouring the internet for this issue shows that this is a widely reported problem. The vehicle was taken to the dealer for diagnosis who offered to replace the transmission for $7500. When asked about the root cause of the issue, the dealer stated that they would not know until they take the transmission apart and would end up costing roughly the same as replacing the transmission. The down shifting presents a danger when making sudden stops due to unforeseen traffic changes in front of the vehicle as braking hard causes the vehicle to down shift quickly which causes the vehicle to lunge forward.

2006 mercedes Ml350 75k no warning light or check engine light/unable to drive,vehicle running. Drive gears not moving or reverse not working/towed to mercedes dealer/service advisory need replace complete transmission will cost 6. 5k to replace transmission. After research. Mercedes u. S. A have a class action complaint. Defective idle gears/these defective gears wear out prematurely,excessively, and without warning,causing the vehicle to malfunction, the "check engine light" to remain illuminated, and the vehicle to misfire and /or store driving. Mercedes actual knowledge and intentional concealment of the defect due to company reputation don't want the public to know and may hurt the company image. I was shock after what I was explained by mercedes advisory not taking any responsible for defected gears and wanted to charge me. Very bad experience with mercedes.

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.

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.

The contact owns a 2006 Mercedes Benz Ml350. The contact stated that the check engine light illuminated. The vehicle was taken to an authorized dealer who stated that the balance shaft and other parts needed to be replaced. The manufacturer had not been notified. The failure mileage was 85,448.

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.

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 contact owns a 2006 Mercedes Benz Ml350. The contact stated that the vehicle would lose power when the accelerator pedal was depressed and the vehicle would not accelerate over 10 mph. The failure was experienced numerous times. The vehicle was taken to a local mechanic who diagnosed and located the failure at the transmission. The vehicle was not repaired. 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.

2006 Mercedes Benz balance shaft is defective. The defect causes the car to sometimes sputter when accelerating, almost was killed by a truck as I turned left, or stall out completely.

Balance shaft on my mercedes Ml350 has worn cam causing checking engine light to come on and the timing to be off. Mercedes service bulletin states that the balance shaft needs to be replaced and that the material of new replacement shaft has been updated. This has happening to nearly all Mercedes Benz equipped with m272 engine up to serial no. 2729. . 30 468993 or m273 engine up to serial no. 2739. . 30 088611 and occurs after 55,000 miles. 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.
