Mercedes-Benz USA LLC faces a possible class action lawsuit alleging that certain models produced by the luxury car manufacturer contain transmission defects.
Lead plaintiffs Charlie Jacquo-Stevenson and Corey Stevenson, allege in their class action lawsuit that Mercedes-Benz model cars containing the 722.9 7G-Tronic automatic transmission are defective.
The plaintiffs claim that the Mercedes transmission in question contains a defect in the 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.”
The plaintiffs further allege that the defective Mercedes transmissions fail “to such a widespread extent that, at one point, [Mercedes-Benz ‘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,” continue the plaintiffs in their complaint, “when the transmission valve body or conductor plate fails in the Mercedes-Benz 722.9 transmission, a real safety hazard ensues.”
The Mercedes class action lawsuit states that the defect causes the transmission to have a difficult time shifting from first to second gear, and prevents the transmission from shifting to higher gears. According to the plaintiffs, this causes the vehicles with the allegedly defective transmissions to be unable to be driven at any speed.
The lawsuit claims that the defective transmissions cause the affected Mercedes-Benz vehicles “to enter what is referred to as ‘Limp Mode,’ leaving the car to ‘limp’ along the roadway in a very restricted and limited fashion.”
According to the Mercedes-Benz class action lawsuit, the car manufacturer was allegedly aware of the defect in the 722.9 7G-Tronic automatic transmissions, but failed to take any corrective actions.
“Because the defective transmission typically manifests itself outside the 4 year/50,000 mile durational 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,” say the plaintiffs in their complaint.
According to the Mercedes transmission class action lawsuit, the plaintiffs seek to represent a Class “of all owners and lessees within California of Mercedes vehicles equipped with the 722.9 7G-Tronic transmission,” subject to several exclusions, including judicial officers and those who have allegedly suffered personal injuries as a result of the alleged defects.
The Mercedes class action lawsuit alleges that Mercedes-Benz violated California consumer protection laws and unfair competition laws. The plaintiffs seek a declaratory judgment from the court as well as an order stopping Mercedes-Benz from selling vehicles with the allegedly defective transmission. The plaintiffs also seek restitution.
Lead plaintiffs Charlie Jacquo-Stevenson and Corey Stevenson are represented by Roy A. Katriel of the Katriel Law Firm and Michael D. Braun of the Braun Law Group.
The Mercedes-Benz Defective Transmission Class Action Lawsuit is Charlie A. Jacquo-Stevenson, et. al., v. Mercedes-Benz USA LLC, Case No. 2:16-cv-00727 in the U.S. District Court for the Central District of California.

I have a GLK350 and the drive shaft broke. Causing damage to O2 sensors and engine light to come on. Then the transfer case gear and shaft need to be replace due to metal noise. All the transfer case bearings were replaced at the same time. This is my second mercedes , never again. What a mess of vehicle, and brand.
I own a 2006 C230 with a 722.9 transmission. Recently I was informed that the previous was recommended to replace the turbine speed sensor.
I own a 2014 e350 with 62000 miles cars been maintained very well always changed oil and made sure car was in its best shape I send the car for service because my transmission was sending sings of failure long story short I got a 12000 bill now I’m seeking a lawyer because cars had that problem since purchase and I explained that to mbusa but cars drives normal if the engine is warm and slips when it’s cold so they told me car was fine
Same issue with 2014 GL450
I have a 2007 S550 4matic and have transmission issues. The car will start, run, and drive for a while, then will just not shift. Staying in first or second gear. I ran my Mercedes Benz scan tool and it is telling me that pressure solenoid d is experiencing an electrical issue. I took it to a foreign car specialist and they have determined that it is a conductor plate issue. I happened to check to see if this was a known issue, and the number of responses about this 722.9 transmission is astronomical. And MBUSA has no recourse for this, except pay them more money for a CRAPPY LUXURY CAR!
Houston, Tx
2010 ML350 4matic 117k miles 722.9 transmission no start and sometime car will start, run, and drive for a while, then will just not shift. Ran icarsoft diagnostics and defected transmission control unit. I am searching for a class action lawsuit in Texas against Mercedes-Benz USA LLC.
Diagspeed for your replacement CONTACTOR plate. The dealer won’t sell you the plate Direct it Has to be sold to a licensed locksmith.
Also? Drain your entire transmission, torque converter, and coolant lines and you’ll need between 12 to 14 quarts to replace it all plus a thermal laser digital thermometer.
When you check your fluid level keep the engine running and fill the transmission (through the transmission drain home) until it’s barely weeping out of the drain hole.
MercedesSource has a great pump-&-fill power drain kit.
MercedesSource also has the updated higher capacity transmission pan and the much much better transmission filter.
Yes you can overfill your transmission but unless you’re stupid crazy about doing so an extra cord won’t hurt it since the transmission fluid not only lubricates but also cause it keeps the transmission operating at a certain temperature (113°F).
Watch a ton of YouTube videos &!you can DIY it yourself.
