2010 DTS · 168,000 miles · Mar 2023

I was traveling on Stevenson expressway at 55 mph when the fuel pump relay overheated and melted, which burned up the REC (Rear Electrical Electrical Center /fusebox). When the fuse pump relay overheated it shut fuel down going to the fuel pump, which caused the engine to stall. When the engine stalled the car cut off, causing me to loose power steering. Because I was traveling in the middle lane of a three lane expressway at a high rate of speed, the vehicle started deaccelerating and I couldn't control the vehicle with no power steering, I couldn't get over to the shoulder. This nearly caused a wreck putting me in harm, because vehicles around me were accelerating at 55 to 70mph. All I could do is put my flashers on. Coast to a stop, and hope no one rear ended me, which nearly occurred. …
