Reason: Left blank Service Advisors' texts attached: 1, 2, and 3 from [XXX] of Genesis/[XXX] of HHI: The dealership’s verbal assessment was that the fuel pump area bolts sheared off due to "outside work" or "over-tightening, I asked for photos to provide visual, metallurgical proof of tool marks or cross-threading to back up that claim, and [XXX] verbally stated they had submitted those to Genesis. I never received the photos. The last attachment (Diagnostic Check). **RESPONSE to dealerships' speculation: ** Under Federal Recall 033G (NHTSA Campaign 26V229000), which directly involves the failure of fuel system retention fasteners, the Insufficient torque on the stabilizer bolts is prone to a bolt backing out even a fraction of an inch; the fuel assembly begins to vibrate violently against it. This creates immense lateral (sideways) fatigue stress on the bolt threads. Eventually, under that continuous vibration and stress, the metal fatigues and shears (snaps) completely off. [XXX] - GMA Case Management - [XXX] assigned me Case #XXX. Provide all requests for completion and docs. An inspection is to take place.
