I waited until late 2018 when the air bags came into the mercedes dealer in annapolis to replace for recall. After that the SRS airbag safety light still comes on. We take it back to mercedes for them to check and clear. They say it was done. Same light comes back on.”

Opened Sep 17, 2021airbags
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at …

On [XXX] the car refused to start due to the electronic steering lock failure. The car was towed to the nearest Mercedes Benz Dealer at Stevens Creek Blvd, San Jose CA 95129. An inspection was done and Mercedes Benz wanted $3457.66 to replace the Steering Lock. This item is a recall item in other years of the C300 Mercedes Benz. Google shows: Mercedes-Benz has issued a recall for the Mercedes- Benz C-Class models, including the C300, due to potential steering lock issues. The recall specifically affects 2015- 2016 C300 models, as well as other C-Class variations like the 2017-2019 C300 Cabrio and Coupe. The recall is due to a potential problem with the Electronic Steering Lock (ESL) module, which is responsible for locking and unlocking the steering wheel. A faulty ESL module can prevent the steering wheel from unlocking, causing the vehicle to be unable to start. We feel that the recall should also apply to the C300 2008 model as it is exactly the same issue and completely incapacitates the car and is a danger to the public as involves the electronic steering.

I honestly don’t know how Mercedes could have used such a cheap metal mix in their brake lines. Every single c300 made before 2012 is at extreme risk of brake failure every winter, the lines rust very easily and cause ruptures to happen as soon as you need to use your brakes in emergency. If you slam your foot on the brakes for a 2008-2009 Mercedes, you are putting your life at risk.

Car has been in and out of the shop. Initially I have been contacting Mercedes about airbag messages and continued message of SRS Malfunction on dashboard. Airbags had been recalled and supposedly replaced on multiple occasions. This SRS continues to remain even after repair or being seen for this issue only for other components to have failed and me having to pay for those in the process. The SRS Malfunction remains an issue until the next issue is affected. Recently an entire Electronic SAM Module Component was replaced as the culprit only to have more issues and the SRS remained. Mercedes has contended that each time they saw the vehicle the the SRS Malfunction was not the problems while other documents were repaired such as battery and SAM. In the meantime since then the car has stalled, components that were working are no longer inoperable. There was a recall that was applied to only specific vehicles of my model year which state the SRS Malfunction was to be replaced and made whole. I never received one of those notices and I will note that my vehicle obviously was affected and should also have this component replaced as it fits the same model year and make of the issues Mercedes has repaired already on affected vehicles. This issue has been on going for several years and Mercedes has failed to rectify this component that makes it dangerous and causes safety concerns for us with the understanding that their note on their website about the SRS Malfunction appeared to me

Car worked fine, all the sudden it wouldn't turn over, I would put the key in and turn it and nothing would happen, I was stuck and had to catch a ride, lucky that I was able, a car company that is supposedly reliable shouldn't allow there cars to completely give out on people during the middle of winter storms and not take ownership, when the customer has taken good care of the car. Talked to several mechanics and turned out it was the Electronic Steering Lock (ESL) module that had malfunctioned probably due to the software and electrical. Due to this only the Benz dealerships can repair, I had to tow it to a dealership and was charged around $2000 after haggling over the price. Terrible experience and should be recalled by MB, I have seen many complaints about this online and was very disappointed there wasn't a cheaper solution. Was both a safety issue, inconvenient and very costly.

Car was inspected by Mercedes Benz of St. Paul (MN). The rear subframe of the car was corroded (inside out) and the crossmember became disjointed from the rear subframe. I could have been in an accident while driving my C300 with a corroded out rear subframe. I was extremely lucky not to be in an accident while I was driving my C300 with a major defect like corroded rear subframe that caused crossmember to become disjointed from the rear subframe. I was lucky enough to avoid serious injury to myself and/or someone else if the rear subframe had collapsed due to unexpected corrosion. Mercedes Benz USA is aware of this defect since 2018 but they have not issued any recall. Since the rear subframe rusts out from inside, there will be no visible defect until the rear subframe fails.

My car has 85,000 miles on it and the Rear Trailing Arm Frame on the drivers side has rusted from the inside out. It is a good thing I have become aware of this, as it was about to break and cause me to lose control of my car. This needs to be recalled before someone gets hurt. In Canada and Germany Mercedes is fixing this for free. Why have Americans not been warned about this potentially deadly safety issue? I am reading many common experiences of cars with less than 50,000 miles on them.

While driving noticed that the car was making a clunking noise from the right rear and car was not stable while making a turn and started to swerve to the right while braking. Jacked up the car this afternoon and see that one of the rear links rusted off from the rear subframe due to rust. Subframe is made of very thin metal that is not resistant to rust. Fortunately I didn't need to perform emergency braking since car is very difficult to control now. Car no longer drivable and needs a new rear subframe to be installed. ~ $5,000 dollars.

The rear subframe is rusted and failing it is unsafe to drive. Mercedes is aware of the problem and has fixed the issue in Canada the UK and Germany free of charge. It would cost me around $4600.00 to fix out of my pocket. I have emailed the dealer where I take my car for service as well as corporate Mercedes in Germany and I am waiting for a reply. Why should I pay when they know it’s not safe and it’s a manufacturer defect ? Are they waiting for a catastrophe before they recall?

Pulled into parking space on side of street and turned off vehicle to pick up restaurant food. Returned to vehicle within 5 minutes, turned the key, and vehicle was dead. 93 year old mother was in car which was now stuck in parking space. We had to open the doors, due to vehicle windows not functioning, to try to prevent inside of car from overheating due to outside temperature. Called AAA, who arrived after about 45 minutes, tried to jump start car, indicated appeared battery was fine. Had to re-contact AAA to get car towed. Waited another 45 minutes for tow truck to arrive. Again checked battery and ignition, battery fine, car was locked in park and steering wheel was locked,. Towing technician had to lift up center console to reach underneath to switch to neutral. Technician had great difficulty getting car onto flatbed of tow truck because it kept slipping back into park. Adding to the difficulty was the location of the car in the parking space on the side of a busy street. Car was towed from Newport, RI to Tiverton, RI to Viti Mercedes dealer, who confirmed the problem. There were no warning lamps, messages or other symptoms of the problem prior to the failure. The final bill to repair this issue was $2,214.15. Upon review of other incidents that occurred with this make, model and year, there have been a myriad of accounts of this same issue going back many years.

The tail left bulb mount carrier part Number 204-820-15-00-64, one of the terminal in the back, is corroded. Also, one of the cable is burnt. In short, the tail lamp doesn’t work. It is a hazard problem since it affects the brake signaling, turning signaling and all other tail lamps signaling. For many years, I have read many incidents like this reported from owners like me and Mercedes has done nothing. I cannot use the vehicle in this condition because it is is a safety hazard.

At only 59,000 miles, the brake lines of my Mercedes C300 suddenly developed a significant leak of brake fluid which caused the brake pedal to go all the way to the floor with minimum function. The car was immediately taken to the dealership where the service dept confirmed that all of the brake lines had become corroded and needed to be replaced. They also communicated that this was a common issue on these vehicles which I have further confirmed by identical complaints raised on the www.mbworld.org forum page. The manufacturer used faulty materials prone to premature corrosion and sudden failure for the brake lines on these vehicles which places drivers at a significant danger and safety risk. There should be an immediate recall of all of these vehicles to replace these defective brake lines subject to sudden failure at the expense of the manufacturer.

Failure of rear subframe at passenger side connection to the lower thrust arm/trailing link that transmits force from wheel carrier to car frame. The bracket portion of the rear subframe for this connection tore loose at the weld to the carrier, possibly during moderate acceleration at an at-grade railroad crossing in downtown St Paul, MN. This occurred on 8/12/21 at roughly 4:15 in the afternoon. The car became difficult to drive and control, requiring the steering wheel to be turned slightly to the right and held there while the car was going straight. The dealership was contacted about the failed subframe but neither they nor the OEM has inspected the vehicle.

TL* THE CONTACT OWNS A 2008 MERCEDES BENZ C300. THE CONTACT STATED WHILE DRIVING 45 MPH, WHEN "THE REAR PASSENGER BRAKE AND SIGNAL WAS FAILURE" WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC AND HAD THE REAR PASSENGER LIGHT PLUGS REPLACED. THE CONTACT STATED A WEEK LATER THE REAR PASSENGER LIGHT PLUGS WERE MELTED AGAIN. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. A DEALER WAS NOT CONTACTED. UPON INVESTIGATION, THE CONTACT ASSOCIATED THE FAILURE WITH NHTSA CAMPAIGN NUMBER: 14V177000 (EXTERIOR LIGHTING), HOWEVER THE VIN WAS NOT INCLUDED. THE MANUFACTURER HAD BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 212,000.
Complaints 1-50 of 672, newest first, reproduced as filed.
Going by the federal record, it is one of the C300 years to avoid: owners filed 672 complaints, 2.5 times as many as a typical C300 year. The most common complaint is about the airbags (39%).
What is the most common problem with the 2008 Mercedes-Benz C300?
The airbags: 264 of the 672 complaints (39%) are about it. Owners most often say it sets off warning lights on the dash (11%), shows an airbag warning light (9%) and did not deploy its airbags in a crash (3%). The typical report comes at 80,000 miles.
How many recalls does the 2008 Mercedes-Benz C300 have?
7 safety recalls on file with NHTSA, the most recent filed Mar 18, 2022. The largest, 16V081000, covered 711,159 vehicles. Recall repairs are free at a dealer; whether a specific car still has one open depends on its VIN.

They include a warranty extension, NCU - 24240304, filed Mar 12, 2024. A bulletin is a repair instruction to dealers, not a recall: the fix is usually free only under warranty.
Reading this record
Complaint volume is well above typical for a single model year.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
Most recent recall on file: Mar 18, 2022. Source: NHTSA Office of Defects Investigation.
