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.

I believe the electrical system may be defective as ever since I have had it the light bulbs frequently have to be changed. We own three vehicles in my households (the other 2 are non-Mercedes) and none of my other vehicles do this. The latest issue with the electrical system is that the rear tail lamp and power lift gate. I was told there was water that was getting in from somewhere but mechanic could not find where. I need a new SAM module and that is why my power lift gate motor does not work. As I did some research online, the same exact problem was recalled on a the same model but the 2009 model and I have the 2011 model. I believe my car should be part of the same recall which I believe is Mercedes recall number 2009030003. That appears to be a faulty seal around the rear tail lamp assembly. I believe this is a manufacturer's defect that should be covered and would likely explain why I have had to change out light bulbs so many times over the years.

Corroded brake lines. This is a well known issue for many ML350s built during this time period. This car was built with steel brake lines that easily corrode and present a serious safety issue. While driving a few months ago, the car suddenly lost the ability to brake because a line rusted completely through. The mechanic noted the lines are rusted in many other places as well. Mercedes refuses to correct this under warranty.

Is 107 complaints a lot? They were filed between 2012 and 2025, roughly 8 a year, which is about the same as the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2011 has 107 complaints on file, more than the 2010 (100) and more than the 2012 (63). That is the most of the 6 model years of the Mercedes Benz ML350 we cover. Older model years have had longer to collect complaints.
