While it was being serviced they asked me if I wanted to replace brake lines for $1200 since they had this part out job would be easy.

I've had the car for 3 years and its all stock. It has 38,500 miles and today out of no where the driver side speaker in the door started making a crackling and popping noise. Smoke started coming from the speaker and filled the cabin. I quickly pulled over and turned off the car, because the smell of plastic burning was horrible. I was immediately alarmed by this and let the car cool down. I started driving again and it started again crackling and alot of smoke coming from the speaker. I called my mechanic and he said that that car had a known problem for a short and others had complained about their speakers melting due to overheating from the amplifier. He quickly searched the fuse box numbers and had me pull fuse #67 that disarmed the amp and speakers but allowed me to drive the car again. There is no warning and this is extremely dangerous due to a possible car fire. I am just thankful that my wife or children were not driving this car when this happened. I researched the problem more and I can't believe there has not been a serious recall for those amps that came with the car.

The camshaft adjuster failure. Though I'm told safety is not in immediate danger, it's a very expensive fix that can cause other issues if left unpaired. It began subtly with strange noises, hesitation during start-up, inconsistent performance. I take meticulous care of this vehicle. Regular service. Genuine parts. Always handled with care. And yet, here I am, facing a repair bill that is not only shocking, but unjust. Especially for this to be a common problem. Not to mention the potential for severe engine damage if left unresolved. I’ve since learned that I am not alone. Many loyal Mercedes owners have faced the same issue; often at relatively low mileage, with little to no warning. This is not an isolated defect. It is a systemic issue with significant implications, not just for the vehicle, but for the trust your customers place in your brand. To say I’m disappointed is an understatement. I feel let down. Mercedes-Benz has always held a status. A great looking car. A great engineered car. And while this is a great looking car, it has a serious engineering flaw. German and Japanese engineered cars hold the standard and this must be fixed. A goodwill repair assistance, or a broader recall initiative would show some integrity.

Rear brake lines have rusted out causing a safety concern. Mercedes will not extend the warranty to repair the recognized inferior parts as they did for the rear subframe. The rusty rear brake lines are related to the rusted subframe which was repaired under extended warranty by Mercedes at no cost. The same should apply to the rear brake lines. I am currently having the rear brake lines replaced due to this rust and safety issue. Please require Mercedes to extend the warranty and related repair to the rear brake lines as it is systemic to these cars.

Dealer reports that, in addition to the dangerous corrosion on rear subframe covered by the extended warranty program, the rear brake lines are dangerously corroded and may fail at any time. I inquired about how this is even possible as I am accustomed to vehicles with cupronickel brake lines that do not corrode. I was told they are merely enameled steel on this model and prone to premature corrosion where they are mounted to the chassis with plastic clips that wear off the enamel and allow premature corrosion and eventually catastrophic failure. I was also told the replacement parts are now cupronickel, indicating Mercedes understands the original design was defective. I believe this should have been covered under the same program as the rear subframe, not be used as an upsell tool to customers affected by that issue. I also believe steel brake lines should just be banned outright for all vehicles, the risk of rupture due to corrosion leading to brake failure is far too high.

As I went to have my vehicle inspected, the mechanic advised me that it could not be inspected, that the car is totaled because the rear subframe is all rotted and the brackets holding the trailing arms were broke off and said that this was a common problem with these vehicles.
