“I purchased my mb GL450 in 2010 and at that time it was covered as a pre-owned mb vehicle. Under the warranty, I had the air ride suspension fixed twice. Once on front left and right. After the warrant expired, I have had to do both sides of my suspension again. Now the front left has failed and needs to be repaired. I have read my blogs and posts about this mb suspension defect and want hope the NHTSA can push mb to issue a recall to fix this failed product.”
