I was driving 70 down an interstate a Saturday around 4:30 pm and heard a noise as if my sunroof opened a bit, then I heard a loud pop and a rush of air and looked in my rearview mirror and didn't see anything, I looked up seen the sunroof was gone. All I could think about is that could have really caused a serious accident. Glad no one was around me at the time. I doubled back twice and could not find the sunroof glass. I got home and put a couple pieces of cardboard and plastic down and duct taped it before the snow storm hits. A day after and my heart is still racing knowing that could have cause a wreck.

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.

Desiccated Air Bag Inflator RuptureOpen
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled…
