Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2007 Mercedes-Benz C280 Owner Comments

In November of 2012 Mercedes-Benz usa initiated a service campaign that affected approx. 1,064,723 vehicles. The defective part was the camshaft solenoid. Mbusa sent this notice to all dealerships, but failed to notify the vehicle owners directly. They apparently did not deem this to be a safety recall and felt no obligation to notify the consumer. However, when the solenoid malfunctions due to the defective part it does in fact affect the performance and driving ability of the car. If driving on the highway, in which is the case here, it does become a safety concern. It seems that mbusa knowingly withheld this information from their consumers. During the time of their campaign my vehicle was also under warranty as well. Mbusa had ample opportunity to notify their customers of this issue to have it corrected. They never actively provided notices to customers directly. Due to the malfunction of the affected solenoid, my vehicle had to be repaired in April 2015. My warranty expired in March 2014. I had my vehicle repaired at an independent repair shop at a cost of $232.93. Mbusa should be held responsible for failure to notify the vehicle owners of this potential safety hazard if not corrected, as well as they should be required to reimburse any out of pocket expenses that were incurred as a result of this issue. I have attached a copy of the bulletin that mbusa provided to their dealerships, but again failed to provide to the 1,064,723 consumers that were affected.

The contact owns a 2007 Mercedes Benz C280. While driving highway speeds, there was a drastic reduction in speed without warning. In addition, the rpms raced and the accelerator pedal was not responding. The contact had to apply force to the accelerator pedal to coast the vehicle over to the side of the road, turn off, and restart the vehicle. The failure recurred. The vehicle was taken to the dealer where it was diagnosed that the automatic transmission needed to be replaced and the transmission shaft, springs, internal speed sensor, and cam shaft needed to be re-adjusted to the correct position. The contact was not able to drive the vehicle. The manufacturer was notified of the failure and provided no remedy. The failure mileage was not available.

Engine motor mounts are constructed of untreated aluminum. It is well known that salt will react easily with aluminum, extensive corrosion results. The driver side motor mount sits in a pocket in the frame, where brine can lay on it for prolonged periods. Of note, many highway departments are now using a brine mix, including magnesium chloride, that will react with moisture in the air to continue the corrosion process. A recent study by Volkswagen confirms that this accelerates the corrosion process. In April or may of this year, I had to have the motor mounts on my car replaced. One failed completely, the other was severely cracked and nearly the same way. The entire top of the driver side mount was completely missing, apparently from corrosion. What was left was white powder. The passenger side also showed evidence of significant corrosion. The mechanic who worked on my car said that this was a known problem, and not the first he had seen. I am extremely concerned about this. A complete failure of motor mounts could cause a severe accident, with wiring and or fuel lines being sheared, and loss of control of the vehicle. The breakage would be likely to occur upon acceleration (think about entering an intersection) or when going over a bump. A complaint was filed with Mercedes corporate offices. I explained that I was not looking for any kind of financial settlement. I am not. I would like the problem addressed. It has been a few months now with no response. This situation is not acceptable.
