This is a diesel-engine 2010 mercedes gl350 purchased in august 2010 (8 months ago). It is currently inoperable and the dealer is citing complete fuel system corrosion due to water in the fuel system. The first indication of a problem was a check-engine light and the vehicle going to "limp mode" (where the computer keeps the car at 20 miles per hour with low power - a danger on the highway and on hills). Fortunately there was no accident or injury due to the onset of limp-mode. But the estimate for repair is $15,492.03 and warranty is being denied by the manufacturer. There was no indication of the issue of water in the fuel prior to the complete corruption of the fuel system and therefore no opportunity to take any potential corrective action to minimize damage. All diesel used in the vehicle was purchased at various retail locations in california. Thus far no detail has been given as to how much water was in the fuel, how long this corrosion process might have taken, or whether there were any malfunctions in any part of the system (e.g., fuel and water filters and/or warning notifications) that LED to this extreme outcome. Given the extreme expense of the problem, and the many questions still remaining as to the cause, we thought it important to bring this to the attention of the federal safety agency.

Tl*the contact owns a 2010 mercedes-benz gl 550. The contact stated that the tailgate motion sensor malfunctioned. When closing the tailgate and there was an object in the path way of it an alarm will sound and the tailgate should reopen. The contact stated that if children were in the area of the tailgate closing the tailgate a serious injury could occur. The contact also stated the suspension was making a clanking noise while the vehicle was making a turn. The contact took the vehicle to the dealer to have the lower ball joint replaced on the front driver side of the vehicle. That repair did not remedy the failure; therefore, the contact took the vehicle back to the dealer to replace the lower control arm on the front passenger side which also did not remedy the issue. The dealer replaced the front struts on the driver and passenger side; however, the failure continued to occur. The final attempt to repair the failure was when the dealer sprayed wax on the suspension and the ball joints. The contact has called the manufacturer regarding the suspension and tailgate but they have not responded. The contact stated that this was a safety issue that the manufacturer was ignoring. The failure mileage was 5,000.

Engine almost stalls when cold. Took to dealer, did a software update. It is better but still not resolved.
