Rusted rear sub frame that needs to be replaced. Premature rusting that mercedes needs to repair at no cost. Also, premature battery drain on new battery. Needs to be fixed by mercedes at no cost.

During service b maintenance, a technician found rear subframe rusted through. Reportedly, there has been a large number of mercedes C300’s with this very same problem, and mercedes has a widely acknowledged the issue with rotted sub-frames. It’s a serious safety issue which led to recalls in other countries.

Rear sub frame is corroded as shown to me by the mercedes mechanic in a video he sent me. The car is available for inspection. I am nervous to drive now after hearing about the related problems others are having such as braking issues and swaying when the brakes are applied. The way I found out about the rear sub frame corrosion was when I needed work done at the dealer. This problem should not be happening to all of these vehicles. In other countries, germany and canada, to name a couple, mercedes dealers are fixing this through a recall. Why not the us? the date below is when the mechanic told me about the problem and that it would cost $8000. To $10,000 to repair.

After parking my car , turned ignition off, did some work for 45 minutes I came back attempting to start the car. The car won’t start, I am not hearing any of the normal sound that usually takes place when I place the key in ignition. Message on dashboard telling me to remove the key. Car will not start. After checking battery and calling mechanic they tell me the my steering wheel lock is bad. The esl went bad out of nowhere. Car won’t start, steering wheel is locked and the only way to fix it is to take it mercedes’ dealer and pay over $2000. I search on google and found out that this is a common issue with my 2010 C300. This is a manufacturing defect and mercedes should recall it and pay for repair. In my case I parked my car in my garage, imagine if I was traveling on highway way and the steering wheel locks or failed on the side of busy interstate hwy. The worst part is that mercedes dealer did nothing t warn me when I bought the car about this issue especially since it is know since 2008, and they will not allow after market parts to be installed by other mechanics. So this is defective and mercedes should be forced to recall and replace for free. We should not wait for someone to die before this is fixed. This happened without any warning please force mercedes to recall and fix the esl now.

Aug 12, 2020 took C300 to fletcher jones motorcars of fremont. I paid for them to do an oil & filter change after they did perform recall 2018120017 ~ 18p9193104 cause: recall 2019120027. Paid $204. 65 that day. 01/21/21- after driving, w my significant other, at city speed limit to fedex which is 1 mile from my house on same street, and back, my sig other couldn't put back the seat and the airbag lights were on. I had to drive to work next day, unsafe. . . Pressed up against steering wheel because I'm 6 feet. Somehow that went away. 03/09/21- I took in the car, by tow truck, back same place fletcher jones and had a bee service per manufacturers specifications service dealt on my car they performed be service with brake fluid flush numerous other stuff I'm also reported to them a misfiring because I did hook up an obd2 but during their road test they just noted a strong vibration from the driveline they ran a quick test found no fault but noted collapsed backslash worn motor and transmission mounts and recommend replacement they also noted voltage related faults however the alternator and battery would pass their tests and they released my car to me after charging me $576. 97. Today, 03/19/21- had to tow my car again from approximately three blocks away because it just turned off on me with a message brake srs edt, and something about it failing. Now. . . Im stuck because mercedes screwed me!.

Mercedes key fob not recognized by ignition. Car locks and unlocks properly but key fob is not detected by car. Key fob battery is brand new. Car is immobilized and not usualable. This is unacceptable!.

Cam solenoid most C300 will stop turning on all the car does is ask u to take key of ignition. . I searched the issue and there is thousands of people having the same issue. It's not fair to consumers not to have a recall on a part that is defective that cost over a thousand to fix . Please help us resolve this matter.

Smell in car gave me a severe headache along with nausea and chest pains. There?s been a noxious odor in this vehicle for three years. No one can find the problem. My grandchildren have passed out in the car from it and it is causing me migraines and other issues. I can no longer drive this car. I need a solution.

Notices of recall; scheduled with dealer and never received a call back to replacement. The call smells strongly of burnt plastic since I bought the car. Every single car maintenance person tells me the car emits that smell.

I got Mercedes Benz C300 2010 in less than 6 months, the vehicle developed power steering lock issue; the vehicle will not start and got me stranded in a parking lot of a grocery store. I researched the problem online and realized several individuals have had similar issue. I brought the issue to mbusa, they did not deny its a common issue but said based on the history of the vehicle I am not eligible for any relieve on the cost of repair. I feel it is unfair that I will have to pay for something I believe its a manufacturer default. Now I am compelled to pay $1,700 for the repairs.

Takata recall. After purchasing my 2010 mercedes c-300 I've noticed a gas smell from the rear passenger side but this has gotten worse after I park my car in my garage overnight. The entire garage and vehicle interior smell like gas. I then notice a gas leakage spot from the rear passenger side tire. This happens when I have full tank or half of the tank full of gas. I red about this online I called the dealership but I was told the recall/ extension tank warranty does not apply to my car. Concerning the seat-belt the rear passenger side seat belt is default. It does not buckle.

Takata frontal airbag and another defective part that I had received an alert about over a year ago, but till today's date has not been remedied. As part is not available.

The rear subframe rusted and broke.

After I turn the car off, the front left light on the top continues to stay on. If I move the knob back and forth slightly, then shuts off, at least for a while. I just had to deal with a dead battery yesterday when I was getting ready to leave work. From what I have recently researched, this is a common issue among this model. Has a recall been made for this? will this cause any other issues with the vehicle? if it is a shortage in the electrical, am I in danger of the vehicle not reacting appropriately while driving at night or at a higher speed on the highway? is there any risk of it catching fire? there is also a sensor that needs to be replaced. I am not that car savvy, but I believe it may have something to do with fuel injection or something filtering properly. Is that another common issue?.

I was driving off the giant food lot today Sunday may 22 when a message appeared on the dashboard stating that the ebr, esp, and abs collision prevention is inoperative. The car downshifted to below 10 miles. I live nearby so I drove the car slowly home and will take it to the dealer on Monday may 23, 3016.

The door handle is broken on the driver side. The driver cannot get out rightaway if there is an emergency. The handle was not forced, it just start moving by itself. Looks life the cable is not atached. This is a safety issue. How come no body is looking at this.

Inside door handles should be recelled due to safety hazard I got trapped in my car and everyone has same issue its a $1600 fix and have to replace door panel.

Bad esl car completely locked not able to do anything was stranded 30 min from home payed too much money for the car that really sucked.

Purchased car March 2015 with a 3 year extended warranty. Inside drivers door handle broke (plastic piece inside door I believe). Dealer claims warranty does not cover this because it is cosmetic and it will cost me in excess of $1100. To get it fixed. This is a major safety issue, one should not have to open the window and feel for the door handle to open the door. In many situations this could be a matter of life or death. This is just as critical as an air bag in my eye. I believe the dealer should cover this under the warranty, and may even warrant a recall.

I have 2010 Mercedes Benz C300, my car would not start with my key even though the battery checked okay. This is a very common failure among C300 models (2008 to 2013). So meaning cars are vulnerable to this failure around 5 year mark. Manufacturer should issue a recall on these parts, as they have a very bad reliability.

I had just stopped in driveway in my house after a 15 mile drive from my office when I tried to open the door, the handle flapped about but did not engage the lock to open the door. I had to start the car again, rolled down the window (glass) before I could open the door using the out side handle. The local Mercedes Benz dealer and the Mercedes Benz USA representative informed that I have to replace the whole driver's side door at a cost of $708 after the local dealer discount. Mercedes benz has installed a plastic handle as a door handle but requiring buyers to purchase a whole door when the plastic handle breaks. Is this allowed? even if this is allowed is it good for the customers? what can you do about this? as far as I am concerned they have lost a four-time Mercedes Benz customer. But I want others not to get caught in this money-pit. Please help.

When trying to exit the vehicle, using the driver interior door handle, the handle no longer engages to open the door. The driver must roll down the window to release the door from the outside to exit the vehicle. In the event of an emergency where the vehicle electrical system was not working, the driver would be unable to leave the vehicle.

Driver's side inner door handle cable connector broke. Cannot exit car from inside and must roll down window and open door from outside. Could be a problem in the event of an emergency. This is a common problem with Mercedes Benz on multiple discussion forums.

Luckily I took car in for a safety check and belt tensioner was found to be shredding. It should last longer than this and is a safety hazard. This extra visit to the dealer may have save me from having an incident. I otherwise never would've know the belt was shredding.

The Mercedes Benz c 300w4 2010 has a problem with the inside door latch. The vehicle was bought as a certified preowned from the dealer in 2013. It has less than 15000 miles. I took it to the dealer today they knew what was wrong immediately. Cost to repair approx. $1000. Looking on line I found numerous people complaining about the same problem. There is an obvious design flaw that mercedes is not willing to accept. What happens in an emergency if you need to get out of the car and the handle breaks? in my humble opinion this is a safety issue that should be looked into.

The door handles are broken on 3 doors causing the door panels to be replaced this really needs to be looked into by mercedes and recalled a mercedes is a high end vehicle and should not have these type of issues.

Door release handle drivers door broke off. Unable to escape from vehicle without rolling down drivers window and climbing out. Dealer well aware of problem, but states it is a wear and tear item and not a safety issue. Will only repair under new car warrantee.

The piece of plastic that serves as an attachment for the pull cord from the inside door handle broke. This made it impossible to open the front passenger door from the inside. I believe this is a safety hazard since the passenger is trapped inside the car and cannot exit easily. In an accident situation, this would be a real hazard. I discussed with local dealer, who advised this happens all the time.

I recently had an issue with my eis on my 2010 C300, the car had roughly 60000 miles when the issue occurred. I parked my car in a parking garage, and when I went to leave work, the car wouldn't start. The steering column was locked, and I was unable to put the car in neutral. The issue seems to be one that occurs in a large number of mercedes cars with similar make/model/mileage, which is generally right outside of the mileage for the standard warranty. Mercedes doesn't allow the issue to be fixed by licensed dealers, and can only be fixed by a dealership. I believe this to be a conflict of interest and somewhat of an ethical dilemma. I am not sure if the eis would ever go out while driving, but if so, that could result in safety issues for the driver.

Went into work and came back out to my car not starting. Battery just recently replaced withing the past 6 months. Had the battery charged and tried to do a jump and still nothing. Had to get my car towed to the auto shop only to find out I have a failed eis, meaning my electronical ignition system has failed and its going to cost me 1000 to fix. My car is out of warranty but I find this a major inconvience. This is supposed to be a reliable car the reason I chose to get this car and something like the ignition has failed. I wish there was something that mbusa could do to pay for a majority of the issue or even do a reimbursement. This can be a safety issue as well, I always think what if I was out of town or what if I had a emergency and because of this glitch I simply have no car and now I'm dependent on a ride until I can get this fixed!.

I went to open my door after I had parked and the driver side door latch broke. So, I had to cut my car back on, roll the window down and pull the latch from outside the door. If you look online this appears t be a common problem with the 2010 C300.

Driver's side inner door handle broke. Cannot exit from car and need to open door from outside. Could be a problem in the event of an emergency if one needs to exit a vehicle in a hurry. I believe this is a common problem with Mercedes Benz from my research.

On approximately 10/06. 2014 the driver side door handle on my 2010 Mercedes Benz c 300 4 matic failed to allow the door to be opened from the inside of the car. On 02/14/2015 the passenger side door handle failed to allow the door to be opened from the inside of the car. In the event of an accident such as fire or submerged in water neither the driver nor the passenger would be able to escape the vehicle. I have been driving over 50 years and have owned 50+ vehicles. I have never had a vehicle interior door handle to fail to open from the inside on any vehicle I have ever owned. To have both the passenger side door and the driver's side door to become inoperable within a 6 month period on a Mercedes Benz seems incredible.
