Mercedes named in class action lawsuit over defect in the 722.9 7G-Tronic automatic transmission

Merceded Benz

Mercedes-Benz-logo small

Plaintiffs bring this action on behalf of themselves and all other similarly situated owners and lessees in California of Mercedes Benz automobiles equipped with the 722.9 7G-Tronic automatic transmission.  As detailed in the complaint, the subject transmission is defective, having a defect in the transmission’s valve body and conductor plate that causes the transmission to fail prematurely and need replacement well before the useful life of the transmission or the vehicle in which it is housed.

As alleged, Defendant Mercedes-Benz USA, LLC (“MBUSA” or “Defendant”) has known about this defect for years, circulating internal Technical Service Bulletins to its factory-authorized dealerships that detail the nature of the transmission problem. Indeed, the defective 722.9 transmission has failed to such a widespread extent that, at one point, MBUSA was unable to supply sufficient replacement transmission components to have the defective transmissions repaired and, as a result, for a long time, MBUSA prevented independent service stations from purchasing such replacement parts.   Worse yet, when the transmission valve body or conductor plate fails in the Mercedes-Benz 722.9 transmission, a real safety hazard ensues.  As a result of the defect, the transmission will have a difficult time shifting from first to second gear, and will not shift to higher gears, causing the vehicle to be unable to be driven at any speed.  The fault will then cause the transmission to enter what is referred to as “Limp Mode,” leaving the car to “limp” along the roadway in a very restricted and limited fashion.   Despite this and despite the clear defect and Defendant’s knowledge of it, MBUSA has failed to take any action.  Because the defective transmission typically manifests itself outside the 4 year/50,000 mile durations limit of MBUSA’s New Vehicle Limited Warranty, MBUSA washes its hands of any liability, fails to disclose this defect, and leave consumers of the affected vehicles, like Plaintiffs, to pay for the costly repair of the transmission to the tune of several thousands of dollars.

Plaintiffs, who own a 2007 Mercedes-Benz S-550 originally equipped with the defective 722.9 transmission suffered this fate, had their vehicle’s transmission fail repeatedly on the roadway when the car had just 57,000 miles or so, and were denied any consideration by MBUSA.   Given MBUSA’s failure to stand behind its product, Plaintiffs were forced to and did pay over $2,000 to have the transmission valve body replaced.  Needless to say, transmissions in cars having only 57,000 miles should not fail—much less should they fail by the thousands in Mercedes-Benz cars across the country.  Plaintiffs file this lawsuit to seek redress for MBUSA’s violations of the California Consumer Legal Remedies Act (“CLRA”) and California’s Unfair Competition Law (“UCL”).

My 2005 slk 350 only has 57,000 miles and entered the limp mode. Local independent repair shops can not purchase the parts forcing me to use the dealership for repair. Cost is over $2800. Car is not drivable causing me a hardship as I need a car for work .

My 2006 Mercedes Benz E350 keeps going into limo mode. I was forced to drive my car to work and would just shift to neutral to shift through the tough gears. My quick fix didn't last long and the car is stuck here at home now. I am currently still paying on my car loan and the car is ruined. Found out it is my valve body and it will cost me $2,745.36 that can ONLY be worked on in the Mercedes Benz shop which is so stupid!! I do not have that, and this car is my only way to work. Currently I haven't been to work in 2 weeks because of this problem. This stupid car ruined everything. Oh and Mercedes doesn't have a payment plan you can get on to help with such a large cost.

While driving home, my car went into limp mode unexpectedly and would not allow my to shift. I used my scanner to check the transmission codes. They are 0748, 0778, 0798, 2716, 2725, 2734, 2810 and 2759. Considering it is highly unlikely that all 8 solenoids fail at the same time, It seems that the conductor plate is likely the culprit. Why is this not being addressed? This could cause major safety hazard for me and my family while driving at highway speeds.

I own a 07 GL450 with 120k miles, love the car but I've had the same issue with mine. Acelerating from a stop light and the car will sometimes get stuck in 1st gear, pull over shut car off and back on and its good. Has been doing this very randomly for a year or 2. Every few months it will happen but seems to occur more often lately. My father in law also had the same issue in his 07 ML350, it cost him around 2000 to have a transmission shop to replace the valve body. Just recently did the Balance shaft on the car MB covered 37 percent of the repairs on that job due to another class action. Hoping this one works out, seems very common with everyone I know that has a similar MB year and model.

I am the owner of a MB 2006 SLK350 with the 722.9 7-speed transmission. The car now has slightly over 100,000 miles but has intermittently displayed the "limp-home mode" failures since the 40,000 mile mark. It does not register the failure codes and transmission shops cannot help me. It has now become an extreme safety issue. Is there any MB remedy for me?

This occurred to my wife just this week and of course when in out of town. We have a 07 gl450 110k and it just up and stopped for no apparent reason. Let the car sit for a few hours and presto works fine for 10 min. Then bam stick again. I spoke with my mechanic he said there was an open campaign on the problem and he specializes in mercedes/BMW told me the only thing to do was to contact the dealer and try and remedy it that way.. I can't afford to be down a car we have small children and work full time.

2006 ML350. Dealers replaced conductor plate and valve body. $2800 out the door. The service advisor reports they get a steady flow of these weekly. Although replacing the plate is almost half the price of replacing the valve body assembly it's recommended to replace the entire assembly if your + 100k. Hard shift problems may occur if you don't. MB will not replace a conductor plate only on a ML350 with + 100k miles.

**** I have a 85% solution for under $ 400.00 ****
1)Remove transmission oil pan and capture all oil in a container to later measure. 2) Remove valve body. 3) Remove TCM (transmission computer module) from valve body. 4) Send just the module to www.ModuleRepairPro.com via EBAY for $ 269.00. They will fix module and send back to you . Follow replacement instructions from Youtube, 10 liters of Oil , gasket and filter can be purchased from Ebay. I'm back on the road and it feels like a new car again. 2007 E-350 with only 59k. I was in full limp mode and had a ( P2768 ) error code. Had to pay the MB Dealer $150.00 just to tell me the error code.
Option...you can fix all 722.9 problems but you will still need to have a shop or the dealer clear the error codes. I cleared my codes with a MB II dianostic tool bought on Ebay. I refuses to give the MB Dealers any more money.

Already replaced the valve body immediately after my 2010 e63's warranty ended. I'm pretty sure I'm starting to have problems again, and not looking forward to another repair.

**** 12 days ago I made a chime in here.**** I fixed the problem myself, you can do it too. The problem is likely to be the TCM transmission control module. No need for any special tools. Important to measure the fluid you remove from transmission when you drop the pan. Follow Youtube videos. To refill transmission use a pump ( like a large syringe ) that can be purchased from Walmart auto department or Harbor Freight . Use the pump to refill the same amount that was removed when the pan was dropped. Note..make sure to use the proper transmission fluid for the 722.9 . I used approx. 8.5 litters. Drop a line to me if you need any help or just to say thanks.. bldrman6@gmail.com

2006 e350..... MB wants $7000 to fix. Turns out the problem is incredibly widespread. We bought the car used....problem started right away. The little dealer promised he would fix. 9 months later here we are and he has done nothing. We initially took a grand to fix the car. It did not work. Now he wants to give the grand back and the broken car. Nine months worth of promises gone. He for sure is not giving back the $2500 down back or helping us end the loan he set up for us. Soooooo disappointed.

My 2007 gl450 is sitting in the auto shop. Mercedes Benz wants 8700 for a new transmission. I only had 113k miles on it, owned less than a year and had done all up to date maintenance on it. It needs a new valve body and conductor plate, but if I get a used one MB won't program it. I can't afford their prices for repairs on a transmission they KNOW has issues. As a result I ended up buying another car while this one sits at the shop with no hope and still making car payments for three years!

****90% Solution for under $ 400.00 **** VERY IMPORTANT
1) Remove transmission pan and capture all oil in a container to later measure. 2) Remove valve body. You can follow YouTube video at this point. It's like removing a shoe box. 3) Remove the TCM (transmission computer module) from the valve body. It's black plastic plate that contains the module.
4) Send just the module ( plastic plate ) to www.ModuleRepairPro.com via EBAY for $ 269.00 . They will fix the module and send same part back to you. 5) I cleaned the valve body, parts, and oil pan with brake cleaner and air dry. 6) Drain torque converter. A very small allen screw. 7) Make sure to measure all oil that was removed. That's it. No special tools needed. DIY
I'm back on the road and it feels like a new car again. 2007 E-350 with 59k. I was in full limp mode and had a ( P2768 ) error code. Optional..Buy a MBII diagnostic tool from EBAY so you can clear all error codes. MB dealer will charge you $ 150.00 just to clear the codes for you. The tool will do it for you. It's a handy tool to keep with the car. After all is put back together you will need to use a pump bottle and a plastic tube to refill the transmission. Same method as putting oil in a boat motor lower unit. Just remember to put in the same amount of oil that was removed from the transmission. I used about 8.5 liters. Drop a line to me if you need any help or just to say thanks.

I bought my car about two weeks ago. 118,000 miles.
I had my first weird mechanical problem with the car tonight. I was making a U-turn and midway it seemed to go into Neutral. but the shifter was still in Drive. I slipped it into neutral, back to drive, nothing. The engine was running but had lost full momentum. The cars behind me were at a red light. While it was in Drive, i toggled through all the drive gears, 1-2-3-4-5-6 and back to D. Still nothing. I put it in Park, turned off the ignition and on again. put it in Drive and it took off just fine.
It's been doing it ever since, twice on the freeway when I was trying to pass another vehicle. I had to pull over to avoid being struck.

I had the same issue with my 2006 ML350 with only 92000 miles on it the vehicle went into LIMP mode while entering a major interstate highway nearly causing a terrifying accident. MB USA restricts the repair of this "mfg defect" and it must be repaired at an MB dealership. The problem will not go away unless repaired. I made MB USA aware of the issue and they denied that any issue exists. I filed an official complaint with the NHTSA so as to alert them that a recall is necessary. It is very easy and can be done on line in a couple of minutes. According to the NHTSA spokesperson, if enough complaints are filed the vehicle issue will be subject to a recall and MB may have to reimburse everyone for repairs. My repair cost was $1500.


Nick F. said

NHTSA indicates that they have at least 200 complaints on this transmission which is used across multiple years and vehicles at MB. Once they get to 500 they start the official complaint process with MB USA.

I have a 2006 MB E350 with 138,000 miles. Just had the fuel tank replaced due to serious leak making it a virtual Molotov cocktail. Now it frequently fails to shift out of first gear when accelerating from a stop. Engine hits over 6000 rpm before I can pull over, turn off engine and restart car. That temporarily fixes the problem - i.e., it now will shift through the gears until problem reoccurs, possibly even the same day. This is VERY dangerous condition. If not able to pull over immediately and stop car this could result in engine failure with car stopping immediately in the driving lane resulting in rear-end collision.

Lucky the Audi was paying attention and got around me and the BMW behind him cam within feet of hitting me while trying to get off of the highway .it is a split second to miss me will it took me a few seconds to get into the shoulder they both stopped to check on me to make sure I wasn't having a medical problem only to find it that it was a car problem and it wouldn't pick up speed. Got it home next morning start put in gear and it shod through all gears but would not even grab in the gears to roll put on jack stands and it would roll that way only this could have left me in very bad highway wreck.this car has already had to have balance shaft problems fixed at my own expense 87000 tops they claim wear and tear .remember when Mercedes was not even broke in till 75000 miles now it is the life of the vehicale

I have a 2011 E350 Bluetec. It has been diagnosed with the conductor plate virus just as the aforementioned. MBUSA will do nothing for me except fix the problem for $2200. This is my 11th Mercedes and I thought that would mean something but am sorry to report they couldn't give a Hoot! I am now driving my new BMW 740i but still have to get the Benz fixed in order to sell it

2006 r500 start to shift hard about a uear ago then finally it just locked up and all the trans fluid poured out. I had the tranny rebuilt a year ago but, the shop didnt replace the solenoids or valve body. The crankshaft sensor went so the car sat for about 8 months. I then replaced both batteries and the hatch lock only for the dum car to go in limp mode and wont move out. Im so fed up the car only has 112,000 miles on it.

2006 C230, although dealer says it has a 2007 model year transmission in it. I purchased the car used. Experienced a lot fo the same stuff. Didn't originally understand the problem when it started. Thought maybe I hit the gear shift or C/S button and did it myself. The first couple of times the gears seemed to stick, but I also realized it "fixed" itself if I stopped and restarted the car. Was on my list of things to do. Then the car went into "limp mode" after a local errand. Car is in the shop right now, having valve body replaced. Bill to be about $2800. The shop confirmed, although they didn't know why I was asking, that it is that transmission.

I have the same issue with my 2007 Mercedes R350. It goes into low gear and fails to come back to high gear. For some time it started working when I switch off the ignition and start back up again. Last week, it wouldn't fix when I restart the ignition. And, when I was taking it to the shop for repair, it stalled on the road and all the transmission fluid leaked on the road and had to tow the car for repair. It is currently in the shop and being repaired.

I took to the auto shop, the diagnosis was that conductor plate needs to be replaced. Because it is a "nag 1 version" the valve body must be replaced with it. The cost of the repair is $1699.00.

I also have the bad conductor plate issue and started in my 06 Mercedes w211 e500 which when taken to dealer and vin ran has the 722.9 transmission dealer only part. Car was only at 59,000 miles when issue when taken in for but not fixed. I habe since ben in a wreck because of the vehicle dropping gears and insurance claim done but the conductor plate is mechanical which the insurance will not pay as well as the air struts going out but fix the body from the wreck and i paid to fix air struts and conductor plate issue still remains. Dealer advised me to get a scan tool which i did that resets the transmission temporarily but is becoming a shorter fix. What a great car if they only backed there car and design issues to a decent amount of time but 55,000 is outrageous. No decent discount and only a dealer part ?

I own a 2006 R350 with 3.5 litter engine, the transmission is in limp mode and dealership will not see the part. My mechanic say that all the DTC are pointing at the Conductor plate. called Mercedes Benz dealer they will not sell the part and want me to tow the car to their dealership for replacement of conductor plate and valve body $2000 or more. The whole fucking thing was replaced 2/2/2009, now Mercedes Benz wants to charge again to replace it. I would like to participate in a lawsuit to have Mercedes sell the parts to aftermarket shops. This is America (the country of free enterprise) either Mercedes Benz cough up some dough and repair these issues on their piece of shit vehicles or allow aftermarket repair shops to purchase the part.

2006 MB R350. 80k miles. Bought used and had extended warranty which just ran out 10/2016. Forward 04/2017, the car suddenly won't get out of first gear. When shifting to drive or reverse there is a terrible jolt. Love this car, but I had a ton of work needed when it was under warranty. Always took it to dealship. Since out of warranty took to my mechanic who said it is the valve body. Should I write to MB? I did repeated complain about a knocking sound when turning which was documented but they always said it was fine.

Same exact issue here with my 2007 CLK 350, with 61,000 miles. Started 2 years ago, happened very sporadically - twice a year. Took it to my trusted German Car mechanic who could not diagnose because there was no error code. This week, the car made a big lurch and clunk into 1st gear but would not go into reverse! For the 1st time, the check engine light came on. Took directly to the mechanic - they tried to diagnose, ended up calling the MB dealership and learned about this issue. Same dang story, only MB can replace the part. So, I will be picking my coupe up tomorrow morning and taking it to the MD dealer.... who knows what the cost will be! My question is - will the new plate be trust worthy or will I have to replace it again??

I have a 2007 GL450. Very gently driven and any other way flawless, 92000 miles. 45 days ago it suddenly went into limp mode while driving - gets stuck on 2nd or 3rd gear and can not switch. When I put in neutral would not go to any gear until I restarted the car. Once restarted car worked perfectly. I never had any problem with this car switching gears smoothly. No leaks anywhere. All servicing up to date done by me with the best oils, filters and parts. No Check Engine light. Scanned with my own OBD scanner and found error P2767. This refers to intermittent or no input from transmission plate speed sensor.
Going into limp mode started occurring on a daily basis, without ANY warning, Engine light or hard shifting - nothing. Car would drive smooth as butter and then when you try to accelerate it would go veeeery slowly. Turning off the engine always solves the problem and it would NEVER happen until the next day or the day after that no matter of the mileage traveled. Contacted MB customer service and MB dealer after some online research and everything pointing in the direction that MB knows about this problem and should pay for it if you persist. To no avail. MB customer service rep bluntly told me best offer is $200 if I repair at the dealer. Error code was also confirmed by MB Dealer. The only problem is that dealer's cheapest estimate for the repair was over $1500.
Now follows the really interesting part. I started educating myself on how the whole system works and really could not find any obvious reason for why this sensor would fail except if it is a defective part. Problem is that this is a very simple device with not much to really brake or malfunction. Hence, before opening the box and trying to repair the part myself and because of the lack of ANY signs of mechanical transmission malfunction, I decided to just clear the error code and wait to see what happens. Well guess what - everything seems and runs perfect now. No limp mode for a whole month since I reset the code. Call me suspicious but I think MB wrote the software to kick in automatically after just one (real or fake?) error is registered and then put the car in a limp mode intentionally after a certain tame has elapsed so you run to the dealer to fix. This also explains why even after repair is done you have to reset the code. I find this a very nefarious way of doing business MB!

There is no TCU in the engine compartment. The TCU is integrated in the Tranny, can be removed from the pan. Not sure if it is advisable to reset the codes. I tried the reset transmission pressing the gas pedal all the way with the key on the #2 position for 15 secs and 2 minutes key off waiting time. Tried disconnecting battery for 30 mins, no luck.

I own a 2007 ML320 CDI with the 722.9 transmission. Havinf the same problems as mentioned above and now told I need a new Valve Body and conductor plate due to a speed sensor that's bad. My local Indy shop cannot fix, because MBUSA will not sell them the parts. This is dangerous as my wife drives this car and when it acts up, her speed or lack of could result in a wreck. Going to cost me well over $2,000 and vehicle only has 104K miles on it...not bad for 2007 model.

I too have a transmission issue with my 722.9. 1st to 2nd and 5th to 6th gear shifts are adapting. Check engine light is on due to codes being thrown.

I'm having the same issue with my 2007 mercedes s550. I was told by the dealership that i need a conductor plate which is over $2000. This is ridiculous
