Gas Recirculation Valve (egr Valve) Problems of Mercedes Benz GL550

Vehicle malfunctioned for the 5th time since June 2017 while driving on the surface street. SUV completely shut down while driving, loss of steering and dashboard illuminates every warning signal including a beeping sound; gears shut down and SUV completely stops was driving. In looking at the history (I'm the 3rd owner), the work performed for the defective camshaft was completed 2 years after the 2009 mercedes bulletin and another replacement to the balance shaft and camshaft was performed 1 year after the 2012 bulletin. In its report, mercedes issued a caution and stated, "new timing chain tensioner must be installed and only after the engine head covers (valve covers) are installed/bottled on. Failure to observe that will result in the over tightening the timing chain which will ultimately lead to engine head damage. " in the car fax report, I see after each repair, the owner sold the vehicle. In looking at my receipts, I see my reports of smoke from the dashboard (fire department came to my vehicle while in route to my son's school to ensure my SUV would not catch fire). I also see requests to replace light bulbs for blown fuse, the battery, wiring issue under the seat, now a new problem related to the can technology. Another receipt work done on the camshaft. Based on my research, the recall relates to the degrading of poor materials used to manufacture the 1st gen suvs. I don't believe there are any reported deaths but it puts many people at risk as I was researching this issue looking for my receipts, I came across another receipt for the ml500 2006 I sold before I purchased my current vehicle. The receipt shows I was seeking service for the engine stopping while driving. . Read more...
