SERVICE BRAKES

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.

ELECTRICAL SYSTEM

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.

SERVICE BRAKES

I was driving locally and when I put on the brakes for a car exiting a street. Immediately my car sensor went on and my car brakes started to fail. It was a very scary situation. This is a known problem with Mercedes. Mercedes has a recall for the brake booster but will not fix the booster without the brake like being fixed. I have reached out to foreign motor car dealerships and this issue with the brake line is a known problem and a safety issue but Mercedes is not taking responsibility for this issue that can kill someone for their parts that are corroding and rotting. Mercedes too years to take responsibility for the brake booster which can kill people and now they are not taking responsibility for their brake line issues that again can injure and kill people.

VEHICLE SPEED CONTROL

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.

SERVICE BRAKES

Previously submitted to webmaster and recorded under Request # [XXX] I experienced catastrophic brake failure while driving the vehicle. As you see above all recalls have been completed and the vehicle has never been in an accident to my knowledge. I stopped the vehicle without incident or damage and had it towed to a repair shop. They determined that both rear brake lines were corroded and replaced them. I didn't think a catastrophic failure was possible in a vehicle with a dual brake system, but apparently that is not the case in this vehicle. How many similar cases have been reported? Do I have recourse to the manufacturer as it surely seems like a failure of the OEM part The vehicle has 101,000 miles on it and is in excellent condition. I am concerned that this type of catastrophic brake failure will be fatal to someone in the near future. I was lucky and was only traveling at about 5mph and was able to stop the vehicle on the curb.

Brakes died in may, 2022 and it took the dealer to September to inspect as it was part of recall. They told me they had to order the part so i called every 3 weeks to see if it came in. In december they said they need to inspect to see if it is covered. Again they inspected and said yes it is and we need to order the part (this is Crown Eurocar Mercedes in St Petersburg). At the same time I called Mercedes USA (they gave me a case number 2-37306691522). They picked up the car in December and since then it has been the same run around. THEY ARE NOT ATTEMPTING TO FIX THE PROBLEM. I am begging your department to help in this matter.
