ENGINE, POWER TRAIN
While driving, malfunction warning flashed on dash, followed by 48v malfunction warning, then engine coolant overheat warning. The car then went into limp mode and finally stopped completely. Luckily this occurred on a residential street and not on a high speed freeway - the car gave very little warning before drastically reduced speed and shutting down systems. A 48 volt battery problem should have a redundant system to prevent the engine from overheating and not shutting down the vehicle at speed. Very dangerous!

SERVICE BRAKES
Dealer reports that, in addition to the dangerous corrosion on rear subframe covered by the extended warranty program, the rear brake lines are dangerously corroded and may fail at any time. I inquired about how this is even possible as I am accustomed to vehicles with cupronickel brake lines that do not corrode. I was told they are merely enameled steel on this model and prone to premature corrosion where they are mounted to the chassis with plastic clips that wear off the enamel and allow premature corrosion and eventually catastrophic failure. I was also told the replacement parts are now cupronickel, indicating Mercedes understands the original design was defective. I believe this should have been covered under the same program as the rear subframe, not be used as an upsell tool to customers affected by that issue. I also believe steel brake lines should just be banned outright for all vehicles, the risk of rupture due to corrosion leading to brake failure is far too high.

SERVICE BRAKES
10/14/21 Was cautioned that the rear brake lines and caliper hoses were very corroded. Mileage 43,185 10/19/22 Cautioned about rear brake lines. Mileage 48,459 12/11/23 Rear brake lines replacement cost $4497. Repair not done at that time. Mileage 53,375. Again cautioned. 10/30/24 service date- Was informed that the rear subframe was corroded and would be replaced by Mercedes-Benz. I have photos from the dealer. There are holes in the rear subframe.The brake lines could be replaced at the same time at a cost of $2820 due to the fact it is in same area. Mileage 58,597 I asked M-B Customer Service to cover the rear brake lines as the under coating was not sufficient to protect the rear subframe and brake lines. They rejected my claim. I was told others have also tried to get M-B to cover this cost and were rejected. My vehicle has very few miles for its age. I have never had to replace rear brake lines in the 40 years I have owned a Mercedes Benz vehicle. I believe that they have not adequately protected the undercarriage from weather. The rear subframe is my evidence. At some point these brake lines could fail. They will be replaced. I want the manufacturer to cover the cost of the brake lines when the rear subframe is replaced. Please advise.

SUSPENSION
As I went to have my vehicle inspected, the mechanic advised me that it could not be inspected, that the car is totaled because the rear subframe is all rotted and the brackets holding the trailing arms were broke off and said that this was a common problem with these vehicles.

FUEL/PROPULSION SYSTEM
My 2007 Mercedes-Benz E63 AMG, which has developed a fuel system defect resulting in a leak. This issue poses a significant safety risk, including the potential for fire and explosion, and is directly related to a known defect that Mercedes-Benz USA has previously acknowledged through an extended warranty campaign.Safety Risk: Fuel system leaks pose an imminent danger, including the potential for fire and explosion, to vehicle occupants and others on the road. Manufacturer Acknowledgment: The warranty extension campaign underscores Mercedes-Benz’s recognition of this defect as a manufacturing issue, Repeat Occurrence: Having experienced this defect in my previous 2005 E500 4MATIC and now my 2007 E63 AMG, it is evident this issue is systemic and not isolated.Ethical and Legal Responsibility: Safety defects do not have an expiration date. Mercedes-Benz has an obligation to address this issue regardless of warranty status.Mercedes-Benz USA recognized the severity of this defect by extending the warranty coverage to 15 years and unlimited mileage for “Covered Fuel Tank Components” in specific models, including the 2003–2009 E-Class (W211). I received a notice in 2015 outlining this warranty extension, which covered the fuel tank, fuel filter/sender, fuel pump, and all related gaskets, seals, and retention rings. Additionally, Mercedes-Benz USA formally notified the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA), specifically the Office of Defects Investigation (ODI), of this extended warranty campaign in 2014. While the ODI concluded that the nature of the leaks "does not appear to present an unreasonable risk to motor vehicle safety," I strongly disagree. Any defect involving fuel system leaks represents a substantial safety hazard, including the potential for fire, explosion, and environmental harm.

ENGINE, UNKNOWN OR OTHER
August 2024, while driving on a 4 lane highway at 65 mph, a warning appeared on gauge cluster saying that Electronic Stability Control and Traction Control inoperable. This caused the car to reduce power, requiring me to quickly pull over. The car continued running but I was limited on mph and gear selection (aka Limp Mode). I turned the car off, allowing the systems to reset. After driving approximately 1 miles, the same warnings appeared. Fortunately, I was within a mile from home at the time so I was able to "Limp" the car home. The next day, I checked the car again by driving in my neighborhood with the result. I had the car transported on roll back to Express Oil and Tire in Barboursville, WV as my "local" MB dealer is an hour away. They checked the car and the Engine Control Module was defective and needed replacement. The cost of the service including new MB parts and programming would be $2,495. I tried for 2 months to secure funding to fix the car to no avail. I had the car towed on roll back again but back to my house. The car has sat since then.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The emergency applied braking system was applied while driving the 2018 Mercedes-Benz E43 AMG on a city street, with no other car or obstacle in the way of the car. Fortunately, there was no other vehicle behind us when this happened. I had the vehicle inspected by a certified mechanic who found no fault codes in the OBD system. He did update the system software of the car at that time.

ENGINE
Mercedes Benz has a recall on several models including E-Class (E 200, E 220, E 280, E 350) experiencing timing chain problems. The timing chain is an important component of the engine, as it helps to coordinate the timing of the engine’s various parts. I am currently having the same issue, but my model is an (E400) which has not been included in the recall. It appears that my timing chain failing, which is causing a number of problems with the engine, including reduced performance and fuel efficiency, and if MB does not recall this model, I am facing complete engine failure.

AIR BAGS
I was involved in a head on collision when a motorist driving in the wrong lane hit the front of my car in the evening of 10/2/24. The impact was huge and my car was totaled. However, my airbag did not deploy and I hit my chest and knees very hard against the steering wheel and dashboard. Airbag deployment is a basic safety feature during an accident particularly in a luxury vehicle like Mercedes Benz that is known for its safety record.

Vehicle went into limp mode at 83,000 miles and it was due to the electronic valve body failing within the transmission. Dealership mentioned it shouldn’t happen in a vehicles lifetime, this includes maintenance at the right interval (60,000 miles), which mine was. I was quoted roughly $3,800 by the dealership but after speaking with corporate it was brought down to $2,600.
