NHTSA Complaint #11585077 — 2011 MERCEDES-BENZ ML350

My vehicle jerks back and forth at low acceleration, and it often goes into limp mode which makes the vehicle only drive at around 20 mph at most. I was on the highway, when this happened. I have a 722.9 transmission, and this is a common problem. Why is the snapping recalled? I have had a checked with Mercedes-Benz of music City when I had gotten my recall work done, and they said that it just needs a whole new transmission. They said that they had never seen an issue like this. They want $16,000. I have been reading and reading and reading I don't know how they have not seen the issue when it's very very common. Again my question is, why has this not been recalled? There are soldering issues for a speed solenoid sensor, and the TCU it makes it go bad. What is going on, and why has this issue not been addressed? I have two toddlers that I drive in my vehicle every single day. God forbid we're not so lucky next time. The only reason why we did not get hit this time, is because we were on the highway at a slow hour of the day. My son is disabled and we are on the highway and in the car a whole lot. If this happens during rush hour, we will be no doubt smacked into by another vehicle.
