The car is not starting. no dashboard no lights no window function no seat function no radio. nothing. Ignition lights are not turning on and the car is dead. Car batteries were newly replaced but understand this could be EIS and Steering lock issues which is common in Mercedes Benz models. Why is Manufacturer not compensating / correcting for common errors on his Models?

There is a crack in the flange causing a fuel leak in my C300 2011 Mercedes-Benz built March 2011. A strong gas smell fills the car.

There is only a one month difference.

Electronic steering locks are failing in these cars at an alarming rate. When it fails, the car will be stranded or if driving the car will completely lock the steering and take away control from the driver. This is a safety issue that Mercedes should be recalling and fixing because it will take people's lives away. Mercedes is aware of this issue but is failing to recall it and considering it as non-safety. When manufacturing the Electronic Steering lock, Mercedes used cheap parts that are prone to failure. This issue affected many years and models of their cars but only recalled a few cars. Once failure occurs, the car will not start and it will be required to tow it to a dealership where repairs over $2000 will be needed to fix this SAFETY issue.

Went to work and came out and the vehicle says to remove key from ignition. Was stuck in the middle of the night in freezing temperatures and had no way to get anywhere. It-??s a common problem that Mercedes knows about and is charging thousands of dollars to repair because it can only be done through them.

My car sound like the power steering has gone it's very loud. Also secondary air flow just replaced and now it's going to need another one at 2000 a pop. Finally the electrics is very weird. Lights will go out then come back on. My day time running lights stay on day and night no matter where I turn the light switch. The day time running light is on even when I turn on high beams. No matter if it's moving or not all these things are happening.

Takata inflators the first recall was February 2016 for the driver side airbag a reasonable amount of time is past the parts were promised in September 2018 and no delivery. Now a new recall of January 2019 for the passenger side airbag inflator has been issued I'm told by Mercedes-Benz usa that the parts will be available September 2019. This is an unreasonable amount of time given the three years of the previous recall not being remedied. Also I'm told by the dealership that the motor mounts are collapsed I can't help but think that this is a defect also subject to recall.

1. takata recall: This recall of a dangerous situation has been going on for about two years now is unacceptable and hazardous to em and my family. 2. law suit: Greg suddreth and paul denton V. Mercedes-Benz usa, llc. On 10/30/17, I had to pay $3445.13 for a repair my balance shafts gears, which we're deemed defective in all M272 engines which is in my C300. However, in the above mentioned law suit, this problem was supposed to have been corrected. When I brought this to the attention to the Mercedes-Benz of modesto technicians, they said I missed the cut-off date by one year. They acknowledged I had the same problem and checked to see if I qualified for a free repair, but later claimed, the issue with the defective balance shafts gears had been addressed. How can that be when I incurred the same problem. The repair should have been repaired under warranty. I eventually had to have the car repaired at Mercedes of pleasanton because modesto didn't have any open appointments. Thank you for your attention in this matter. 3. faulty electronic stearing lock: Engine won't turn on and steearing wheel is locked. Several people have had this same problem. Mercedes claim not a safety issue, but when your daughter gets stuck at midnight at an amusement park on high school senior night...that's a safety issue. Thank you for your attention in this matter.
