1 Hydraulic Power Assist Steering System problem of the 2008 Mercedes Benz ML350

Failure Date: 10/04/2011

We took the 2008 Mercedes Benz ml 350 in to a local mb dealer for a schedule a service and transmission flush and asked that an oil leak on the front driver's side axel be inspected. We were told that the vehicle needed the steering rack input shaft valve assembly replaced. We called a local shop to get a second quote for the work and were told that they wouldn't quote us or touch it because of a recall on the model and year -- NHTSA campaign id# 08v682000. We called mb back, and they told us our VIN wasn't included in the recall, but we could request to have a post-warranty coverage or partial coverage determination made. This is still up in the air, but I'm anticipating they decline partial or full post-warranty coverage and would just like to know more about how this VIN was excluded from the affected population.

3 Hydraulic Power Assist Steering System problem of the 2006 Mercedes Benz ML350

Failure Date: 12/25/2006

The contact owns a 2006 Mercedes Benz Ml350. The air bag light beeped and remained illuminated. At 10,000 miles, the vehicle was serviced. Afterwards, the contact heard a noise in the rear of the vehicle while driving between 20-50 mph. The dealer test drove the vehicle and was unable to duplicate the failure. On December 25, 2006, the contact was involved in a crash and the air bags deployed. There were no injuries. A police report was filed. The vehicle was serviced after the crash. Three to four months later, the tires were losing air rapidly and the low pressure light illuminated, which indicated there was not enough pressure in the tires. At 20,000 miles, the vehicle was serviced. After the repair, the contact stated that the noise was becoming louder in the rear of the vehicle. She paid $600 for the repair and the dealer stated that they did not hear a noise after diagnosing the failure. At 26,000 miles, the vehicle failed inspection due to the tires, struts, shocks and a power steering leak. She called the sales dealer and they informed her to take the vehicle to a dealer in another state. The vehicle was towed two and a half weeks ago due to the power steering leak. The part for the repair had to be ordered from overseas. The dealer stated that they replaced the shocks, but the noise grew louder. The dealer also stated that the cause of the noise was due to the shocks. On January 24, 2008, there was an odor present and the noise recurred. After inspecting the vehicle, it was discovered that a belt was off track. The belt was adjusted and the dealer jump started the vehicle. The vehicle was towed to the dealer again on January 28, 2008. The computer had to be reset, but continued to malfunction when the vehicle was purchased. The current mileage was 26,206 and failure mileage was 7,000.
