I have video available that shows significant premature corrosion of the rear subframe and brake line. The safety of others will be put at risk at the time of failure. Failed subframes can lead to loss of control. This problem has been identified and the part inspected by a Mercedes dealership. There are no warning lamps or messages to alert the driver that failure is imminent. This was discovered in the process of the car being serviced for an unrelated emissions recall. Many Mercedes owners report having severe rear subframe and brake line corrosion issues on message boards. Some reported their cars unexpectedly sway and drift to one side while breaking. In multiple European countries, Mercedes is apparently aware of the problem and is voluntarily replacing the rear subframe for free. However, in the USA, Mercedes is quoting their customers approximately 6,000 to 7,000 to rectify the issue. Without NHTSAs intervention, dealer service departments will continue to profit from the failure of this critical component. Customers unprepared to pay for such a significant repair will defer maintenance until they can afford to address the matter. Some of these cars will be dumped at trade in and passed on to unsuspecting consumers. Those consumers may be your friends and loved ones. We need government to step in and protect the public interest. -€œIf not you, then who" If not now, when"-€

Camshaft sensor leaking oil into engine harness and ecu. Misfire

- Brooklyn, NY, USA

Totally puzzled.. Intermittent misfire from.exhaust. not a very loud backfire sound. Sounds like a fart or gurgle from exhaust only when I start the car sometimes. No check engine light No lights on the dash Car runs fine, accelerates normal, no ticking, vibrating or shaking..no rough idle Put on a code reader No codes pulled Only misfires after being driven engine turned off and back on. Starts fine. Went to several mechanics and unable to assess misfire due to it being random Spark plugs and coils changed Air filter and cabin filter changed No leaks in the exhaust Looking for answers

Pre-safety inoperable message comes on and the car acts sluggish this can be dangerous and risk the safety of the occupants of the vehicle, I found several people with the same complaint on different models and years may be Mercedes should be forced to recall the cars affected and fix the problem. Thank you
