AIR BAGS
I was in an accident that caused my car to be a total loss. I was hit near the front left side, close to the driver's door. The airbag did not deploy despite the hard impact. I am currently having to go to therapy due to impact. My right lower arm was bruised from the impact, and I was in a lot of pain due to the bruising caused. I am assuming the bruising came from the hit to the steering wheel. I was never notified of an airbag recall.

STEERING
Car would just shut down intermittently, sometimes sudden death. No crank no start. Been stranded at night alone with my child in the car and at times, unsafe areas. Electronic Ignition Switch is faulty and MB has had my car for 1 month to date. Quoted me a repair cost of $2,787. Said the EIS is on back order with no ETA, and they currently have 5 others with exact problem, ignition switch. So many people have reported this problem for years with the C300. I'm a single mom, it's been a nightmare.

UNKNOWN OR OTHER, SUSPENSION, SERVICE BRAKES
Completely rotted & rusted sub-frame. Caused braking/stability/steering issues and was completely undriveable. Cost $2300 to fix, another $1000 for car rental as well as lost time at work. There have also been many reports of this problem with other drivers of the same model of vehicle. NO warning lamps or messages whatsoever, only knew the level of damage once I brought it into auto shop.

SUSPENSION
Car has approximately 60,000. miles. Upon it's state inspection Mercedes Benz service center indicated rear subframe is rusted. Service advisory says it is okay now, but will need to be replaced. Searching Mercedes forums, I've noted this is a n oft reported issue. Many do not realize there is an issue until it breaks and car pulls to one side at rear upon braking. Others have experienced rusted brake lines at the same area as the subframe issue. Others have noted damage to the gas tank from suspension parts banging the fuel tank after it breaks. I realize this is a 8 year old vehicle. But the vehicle shows zero signs of rust on the undercarriage except for the subframe. Sure seems like a manufacturer's defect that should be recalled by Mercedes. Because of safety concerns, I now have to decide to repair or trade the car because of safety concerns. But the rusted subframe zaps the value I thought I had in the vehicle for a trade. What is the protocol for manufacturer's to issue safety recalls. Sure seems like this one qualifies.

STRUCTURE:BODY
Malfunction of rear subframe and control arms due to rust causing the subframe to crack. When breaking the rear wheels swerved almost causing a collision on the highway. My mechanic inspected the car and deemed it unsafe for driving as this can cause injury or death to me and others. The car is currently being repaired. This problem is being ignored by MBUSA, however MB in Europe acknowledges the faulty metal and will repair at no cost. There were no warning lamps or messages that made me aware that the subframe is rusted and cracked.

ENGINE
On December 14, 2022 at approximately 3:45 pm in rush hour traffic in the high speed lane on i-75 in Bradenton, Fl, the 2014 Mercedes C250 I was driving lost total engine power, traveling from 80mph to 0 in seconds. I had just enough time because of the momentum of the speed I was traveling at to maneuver the car into the breakdown lane adjacent to a median construction site. Had I been traveling in the middle lane there would have been insufficient time to change lanes in heavy, fast traveling traffic and get to a breakdown lane. In other words, we could have been killed. There was no check engine light nor warning lights of any kind. The engine was quiet and there was no engine rattling noise or shuddering prior to the incident during over 7 hours of travel from Marietta, Georgia into Florida. The car had been purchased from a used car dealer in Marietta two days before and had passed the Georgia emissions test on 11/18/22. We had the car towed to a Mercedes Benz dealership 20 miles away in Sarasota. On 12/16/22 Mercedes mechanics deemed the catastrophic engine failure to be due to a broken timing chain (this was confirmed in a conversation12/21 with Mercedes Sarasota Service Manager Jim Foulkrod) and that there was no compression in the engine. Among the codes which came up during Mercedes multi-point inspection was 036562, exhaust cam signal and 34164. Mercedes’ estimate to fix the car was $24,222.13. We declined to move forward with engine repairs. Mercedes was threatening to charge storage fees so the car was donated to the charity, Veteran Car Donations, Heroes on the Water which towed the car on 12/20/22. The car remains with the charity awaiting title transfer information.

Interior driver door handle not operating. I brought the car to the mechanic and he states this is a common problem and the whole door panel has to be replace for 1000.00. I went home and researched repairs on this and this is a very common issue with mercedes and many mechanics including the one I went to doesn't understand why this is not a recall. This a very serious safety issue. I have to lower the window to get out of my car. If I have to get out quickly it is impossible. If the window stops working I cannot get out of the car. This safety issue affects me and my passengers if I have to get out of my car quick such an accident or fire. The quality is so poor on these plastic parts of the handle and removing the door panel is complicated because it not meant to be removed and taken apart. I am a nurse that was traveling in Nevada when this occurred.

I received a notice several years ago for the airbag to be replaced due to a recall. Mercedes-Benz has not been able to remedy this issue for years. I have called for several years, but the Mercedes dealer near me continues to state that the airbag part is not available. I called Mercedes hotline (877-496-3691) a month ago to report the issue. No one answered so I left a voicemail. I received no contact from them. I called last week 3 times in a row and finally someone answered. I opened a claim with them for the escalation team. They said I would receive a response in 48 hours. I received no response.

SERVICE BRAKES
With no prior warning indicator on braking issues with my 2014 C250, I travelled from Ormond Beach FL to Savannah GA, on I-95 with one stop in Kingsland GA. I still had no warning indicator on breaking issues as I took the off-ramp to Savannah. A failure occurred with the braking system as I exited I-95, with no vehicle warning indicator shown before or after I came to a stop. I had to exert maximum pressure on the brake to stop, requiring an expansion clear length of off-ramp to do so. An elderly, weaker person or even my wife wouldn’t have had the strength to stop over the distance I stopped it in. Luckily there was no vehicles stopping in front of me, otherwise I would have hit them at high speed. At Savannah Mercedes they found a Faulty Vacuum Pump, & like me were perplexed that no prior warning indicator showed up on my vehicle. This issue has obviously caused me great concern & indicates an inherent dangerous & life-threatening condition with my, & I assume other 2014 C-250’s, if not other years and models. If this dangerous failure had occurred on I-95 as traffic slowed to a stop, I would have run into the vehicle in front of me & my wife & could have been killed. More menacingly, it would most probably have been reported that I wasn’t paying attention & it was my fault rather that a catastrophic dangerous manufacturer failure with my vehicle. It sadly seems to me that this scenario may actually have happened with some MB vehicles and the driver/s are not around to say.

During an oil change (11/9/2022), my technician found rust on the rear subframe. He stated that this is a known safety problem caused by defective materials during manufacturing. He stated that Mercedes is aware of this problem but has not issued a recall as of this date. I checked the online Mercedes forums and the problem is very common with the C-class W204 models. The car has been running fine and I received no warnings other than what my mechanic told me. I want to know when Mercedes is going to issue a recall to get this fixed before it's too late.
