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 …

The contact owns a 2009 Mercedes-Benz C300. The contact stated that while starting the vehicle, the check engine, seat belt, and air bag warning lights illuminated. Additionally, the headlights and navigation lights failed to activate for a while. There was burning odor inside the vehicle with the heat activated or turned off. The contact also stated the vehicle failed to start for three days before eventually being able to start. The contact attempted to charge the battery, which resulted in a visible spark. The vehicle was taken to a dealer where it was diagnosed with a sound module and the Signal Acquisition Module (SAM) failures. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 217,000.

Vehicle inspection by independent service center indicated that a new rear frame was necessary. This was the second communication to nhtsa on this issue. This automobile (2009 c300) is inoperable due to this Mercedes rear frame defect .

The problem is that the steering wheel locking mechanism has failed. The vehicle could not be started or driven. It required a flatbed tow to an authorized Mercedes repair facility. It was diagnosed as the steering mechanism, requiring replacement. The cost for this repair is $1400.00. I researched this problem on the MB website and it stated that this issue was common. I feel that this is a safety issue and should be repaired free of charge or at a significant discount. The car is currently being repaired, and I can forward any relevant documentation to you once the repair is complete.

Went to the Mercedes dealership service department to replace the rear subframe that suddenly broke while I was driving due to extreme rust/corrosion. The dealership stated that it was being covered under the extended warranty due to the recall related to the rust/corrosion issue with the subframe. I was advised by the mechanic that the brake lines will need to be replaced due to extreme rust/corrosion in the rear at the same exact location of the rear subframe, making the vehicle very dangerous to drive because the brake lines could break at any moment and cause sudden brake failure. I was quoted a very significant amount to replace the rusted brake lines and per the dealership, it will not be covered under any extended warranty and/or recall.

The contact owns a 2009 Mercedes-Benz C300. The contact stated that while driving at various speeds, the rear end of the vehicle would fishtail and become extremely unstable while driving over a bump in the road or while turning. Upon inspection, the contact discovered that the subframe was severely rusted. The cause of the failure was not determined, and the vehicle was not yet repaired. The local dealer was notified of the failure. The manufacturer was not contacted. The failure mileage was 201,000.

I drove my car to get lunch. Came back out to go back to work and the car would not start. Would not even turn over. My Radio did not turn on and I couldn't even roll my windows back up. Luckily they were only cracked open a small amount. My steering wheel cannot be turned, it's locked in it's current position. I am told the ESL (Electronic Steering Lock) and possibly the EIS is the cause of this problem. The display on the dash says "Take your key from ignition" and that is all I get. Had to have my car towed and now I have a dead car with the windows partially open that I cannot close.

Headlight harness on drivers and passenger side is melting and my lights are flickering. I was advised to night drive my vehicle at night, because it could start an electrical fire. This is caused by heat from the lights.

The contact owns a 2009 Mercedes-Benz C300. The contact stated while driving and activating the turn signals, the taillights were inoperable. Additionally, the contact stated while driving and depressing the brake pedal to come to a stop, the brake lights were significantly dimmed except for the third brake light. The vehicle was taken to the dealer, where it was diagnosed with electrical failure. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 14V177000 (Exterior Lighting); however, the VIN was not included. The manufacturer was notified of the failure and informed the contact that they could not assist because the VIN was not included in the recall. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

The entire rear subframe of any W205 body model including but not limited to the C class from 2009-2014, CL class, SL, class ETC. suffers admittedly from MB USA, premature rust, deterioration etc. there is an active recall for these same models in Canada and all of Europe but not the USA. My garage kept 2009 C300 has suffered extensive rear end damage from a factory defect that Mercedes refuses to recognize in the Continental U.S. but will admit the same issues occurred in the EU and Canada. Keeler Mercedes, USA, of Colonie New York, stated they completed my subframe repair under the MB rear subframe extended warranty. The vehicle was driven home and inspected only to find out Keeler Mercedes of NY did NOT replace this crucial safety component under MB-USA extended warranty issued for this defect. This is pure negligence. When asked why the subframe wasn’t replaced as the work order stated it did, they stated “a mix up in paper work” I believe Mercedes-Benz USA and Keeler Mercedes of New York conspired together to push this massive safety defect aside and lie about completing the work in fear of the payment from warranty not being worth the labor hours required by the technicians. This oversight COULD have been a multi million dollar lawsuit if any injury was sustained after said repairs were done in belief the vehicle was safe to drive. Keeler Mercedes’ has also had this vehicle in their possession from June 14th 2024, to todays date, July 5th 2024 with no word on when repai

The contact owns a 2009 Mercedes-Benz C300. The contact stated that while driving at an undisclosed speed, the "SRS System Requires Service" was displayed. The air bag and check engine warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the vapor canister shutoff valve but had not provided a diagnosis for the SRS system. The vehicle was repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 99,000.

After noticing brake fluid leaking I took my car to a local automotive shop and when he raised it to checkout the break line when he found the leak from the rust . he noticed a more serious problem that the subframe was rusted out on each side. He told me to contact Mercedes immediately because the car is unsafe to drive.

Last week just before Thanksgiving my car of 134,000 miles wouldn't start. Had it towed to my mechanic only to find out like so many others that the Electronic Steering Module(ESL) is 1,500.00 defective. Yet with this being a common issue there is no recall. guess I'm going to a Toyota.

As I was driving from work, I noticed that when I started using the brakes I starting hearing a metal sound coming from the back, the day after I looked down and realized a whole part from the sub frame was completely broken and the part is corroded.

The caption and case number is Sowa et al v. Mercedes-Benz USA, LLC et al., [XXX] MBUSA has extended the warranty on the rear subframe of several vehicles. The link to this in on your website: [XXX] One the last page of the PDF file on your website it states: When will customer letters be mailed for this warranty extension? The warranty extension customer notifications are scheduled for mailing on: March 10, 2023, and continue in waves through May 19. We have three cars in my family that are in this "extended warranty" at three different households. No letter was received at any of the three households regarding any of the three cars. If you look up the three cars Vin #'s, all three have no recalls on them and nothing relating to an extended warranty on a rear subframe. So, MBUSA, has brilliantly side stepped issuing a recall which would come up on a Vin $ search. They have not sent out the letters of notification. So, almost all owners will not be aware of the deadly impending time bomb they are driving. As these cars age further the ones that have yet to fail will fail and people will die. I called today, 10/24/2023 Reference # for the call [XXX] to let the NHTSA know the above and that if you allowed MBUSA to NOT issue a recall because they agreed to send letters of notification - well they did not do that and people are at risk. This seems like a loophole to me. No recall, we will extend the warranty and then not let anyone know much lower cost than recall and fixing. The

The contact owns a 2009 Mercedes-Benz C300. The contact stated while driving at an undisclosed speed, she became aware that the coolant level was low. The contact added coolant to the reservoir. The contact stated that the coolant reservoir burst open. The vehicle was towed to an independent mechanic who replaced the coolant and hose. The vehicle was taken to the local dealer but was not diagnosed or repaired. The vehicle was repaired, but the failure recurred. Additionally, the indicator lights became inoperable. The check engine warning light was illuminated. The contact stated the failure was associated with NHTSA Campaign Number: 22V168000 (Exterior Lighting, Electronic Stability Control, Engine and Engine Cooling). The manufacturer was contacted, but no assistance was provided. The failure mileage was unknown.

Was told by a mechanic that there is a safety recall for sub frames on Mercedes vehicles. After an inspection the mechanic noted that it was suggested to replace due to a recall on the c-class models. After looking up the VIN it suggested that a 2009 does not have a recall - same sub frame issue.

The contact owns a 2009 Mercedes-Benz C300. The contact stated that the coolant warning light was frequently illuminated due to low coolant. The vehicle was taken to an independent mechanic where the engine hose and other engine parts were replaced. Despite the repair, the coolant light returned soon after the initial repair. The contact then took the vehicle to a dealer where the failure was linked to NHTSA Campaign Number: 22V168000 (Exterior Lighting, Electronic Stability Control, Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

The contact owns a 2009 Mercedes-Benz C300. The contact stated while driving approximately 65 MPH, the instrument cluster started flickering and the vehicle stalled. The contact stated that the power steering and brakes were operable. The contact pulled off the highway and shifted the vehicle into park(P). The vehicle failed to restart and was towed to the dealer. The vehicle was not yet diagnosed or repaired. The manufacturer had been informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 22V168000 (Exterior Lighting, Electronic Stability Control, Engine and Engine Cooling) however, the VIN was not included. The failure mileage was approximately 119,000.

I was driving in the highway 50 mph and i was braking and my car slipped in the other line of the highway and almost had and accident !!!! and cars switched off when driving almost had incident!!!! i saw that many people have the say problem like me about rusted component please do something because people are losing their lifes.

This car I have owned since brand new and I am the original owner. This car has never been used in winter despite I live in New York and always has been maintained in very good condition however, this car has developed noises from the rear when driven. I took the car to my trusted mechanic and he found out that the rear subframe has corrosion making it unsafe to drive.

While driving and when parked the headlights flicker on and off. I have no headlights while driving at night, during adverse weather conditions and during dawn hours. I could crash into other drivers, or they could crash into me because they can’t see me. When a parking bulb blows it fuses and melts everything together causing the replacement of the entire headlight unit, this has happened twice.

The contact owns a 2009 Mercedes-Benz C300. The contact stated while driving at various speeds, the vehicle would sway from side to side as an abnormal clonking noise would emit from the vehicle without warning. The vehicle was taken to an independent mechanic where they discovered that the subframe had cracked due to severe corrosion. The dealer was contacted about the failure, and she was given an estimate for the repair. The manufacturer was also notified of the failure and the contact was given a case number. The vehicle had yet to be repaired. The failure mileage was 94,200.

The brake lines and subframe were completely rusted and the vehicle was unsafe to drive. Dealer confirmed at regular service appointment. I have documentation and competed all regular maintenance. Dealer would not cover costs for what appears to be a major defect. I had another shop replace the brake lines and subframe.

Authorized Mercedes Benz dealership in Ann Arbor, MI advised replacing tires, valve stems and other items. I dropped off the car at the dealership for the work. During Alignment they found right rear out of spec due to subframe rusted out. They said rear subframe replacement is needed. This is a very dangerous condition and Mercedes Benz does not cover rusted subframe replacement costs at all, neither do they advise routine checks for this problem which seems to be a very common issue for the C Class. In Europe and Canada, Mercedes replaces rusted subframes for free. Why is it not done for free in USA? This is a very serious issue and can cause serious and fatal accidents. The cost to replace rusted subframe is very high and car can break down while driving without any notice or warning. Additionally, there is no warning light or signal displayed to alert the driver of a potential problem. The car can have an accident without any warning light or alert.

At a recent VA state inspection the mechanic noted that the "rear sub-frame rusted and rear coil springs bottoms are weak." This becomes a potential suspension issue and the sub-frame should not be rusting out so quickly. Additionally, when researching online it seems prohibitively expensive to replace the rear sub-frame but this is a safety concern and I have noted that a large number of these sub-frames are being replaced..

The stability control is off in the rear. No warning lights or noise. Other models of this same year make and model have been recalled for something having to do with this. Please help me our family can’t afford this rn. We have a beautiful 1 year old that needs rides to dr apt

I bought this car for my 18 year old son based on Mercedes reputation for safety and longevity, only to discover that Mercedes has a widely acknowledged issue with rotted sub-frames -- it's a serious safety issue and recalled in other countries. My son was was driving on the highway and the tire exploded. He was so close to being killed because the car went out of control. After getting it towed to my mechanic, he advised me that alignment adjusters were stuck, the subframe was rotted, the lower control arm subframe mounts were broken from the subframe and they were hitting the gas tank. Luckily, the tire only exploded as oppose to the entire vehicle bursting in flames. There were no warning lights or messages, only the feeling that the tires needed to be aligned. We bought new tires and were told an alignment was done from Town Fair Tires, which was untrue. My son's life was in immediate danger. Shame on Mercedes for not recalling this subframe. This is the first of many avenues I am taking to have this rectified and hopefully prevent a tragedy

Suspension Cross-Member - Mercedes-Benz (204-350-01-41) Driving regularly suddenly fill like the rear passenger side tire moved unevenly, then went to the tire shop, and when they take out the tire see how the rear frame was rusted and broken in a straight line exactly in the middle of the tire hole area. Then start to check used cars to donate that part and All of them have the same trouble in that piece, so I decided to review the frame and discover that the rust begins to damage the opposite side too, so I'm pretty sure is a component failure in metal and materials more than simple rust.

I took my vehicle to the Mercedes dealer for inspection on 7/13/22. It passed inspection, but I was told that the brake lines were very corroded and they recommended replacement before driving. Their cost to repair was $2825. I only have 54,000 miles on the vehicle. I checked on the internet to see if there were any other reported brake line issues with a 2009 Mercedes C300 and was shocked to see how many people had the same issue, some reporting that they lost brake power and had a very terrifying experience. Of course I am now afraid to drive the vehicle and not sure what my course of action will be. With the number of reported incidents, I feel that Mercedes used inferior materials that corrode readily and should have some accountability in remedying the situation. I am including some photos of the corrosion that were provided to me by the dealer.

My spouse was driving approx 40MPH. Traffic light turned amber so she applied the brakes, at that point the vehicle pulled violently to the left into on coming traffic and at the same time the vehicle rear end was fish tailing out of control.Our mechanc inspected the vehicle and discovered the rear sub frame assembly had cracked on the driver side. We were advised by the mechanic this car is un driveable. Our Insurance appraiser inspected the vehicle and stated this is very common with this model vehicle and is a very bad design flaw. I contacted the Mercedes dealership and they advised there is no re-call on the subframe so I would need to pay $4000-$5000 for the repair. This vehicle is worthless to me now and is a grave safety risk to drive. I do not have the funds to fix this vehicle so I am now without a car. Mercedes customer care will not even answer any telephone calls. I have called 3 times and been on hold for over 60 minutes each time. This design flaw needs to be corrected by Mecedes before someone gets killed.

Take my car to the dealer and told me my rear subframe is rusted out and is dangerous to drive. Total cost replace they said around $5800 . Why there isn’t recall for the problem in the USA ? I find out there is one in Canada and Germany for this car. What I’m supposed to do with the car? Take it to a junkyard because Mercedes’

Rear subframe rusted through near connection with control arm. This left the rear wheel connected to the rest of the car only through an axle and sway bar. This is a very common issue on these vehicles, and was remedied through the replacement of the subframe.

K frame and sub frame deteriorates. There is a recall in Canada.

I noticed my right tail light has completely went out and related damage to the brown wire connected to the entire casing. Per recall campaign: 2014050001; NHTSA RECALL NUMBER: 14V177, "Oxidation on the ground pin connector for the rear tail lamps of subject vehicles can result in a dimming of the tail lights or loss of tail lamp functions. The loss of a rear tail lamp reduces the rearward visibility of subject vehicles, especially with respect to turn signal illumination and may increase the likelihood of a rear end crash". I recently called a new certified Mercedes Benz dealership near me who states this recall has been closed, however, there is no specific indication on whether that was the right or left tail light. Regardless, a recall covers both whether it happens simultaneously or at different increments. My requested resolution: to simply acknowledge the recall to replace this time the right tail lamp. Especially since any wiring issues poses risk of shortage or fire.

My 2009 Mercedes Benz C300 4 Matic sedan fishtails at the rear end when I apply the brakes. I’ve owned the car for 8 years. Prior to this happening, I took it to the Mercedes Benz Dealership Repair shop, it was fully inspected on a hoist and fully gone through from bumper to bumper. May 6, 2021, I have a report and a video of the inspection but nothing was revealed related to the undercarriage suspension subframe rusting. Just a few days ago, I had rear brake work done thinking this was the problem and would solve the fishtailing when brakes were applied, maybe one of the calipers was sticking. I also had a 4 wheel alignment, however to my surprise the problem worsened. I called a Local mechanic, who offered to look under my car. After inspection of my vehicle it revealed that the rear undercarriage subframe is completely rotted out. I was advised that it is completely unsafe to drive and to immediately get rid out it to a local salvage yard. My Dream Mercedes still looks new on the outside as I have taken miraculous care of it over the years. Be aware everything that looks good on the outside can be rotted out on the inside. I live in a city that requires highway driving at 70 mph plus, this problem could have ended in a disastrous deadly way. Thank goodness my guardian angel was looking out for me. I checked into repairing the vehicle, the rear subframe is available and with labor the total cost of repair is well over $5000.00 with labor costing $1632.00 before tax alone. M
