NHTSA Complaint #11662286 — 2023 HYUNDAI SANTA FE HYBRID

I am reporting an URGENT REQUEST IMMEDIATE ACTION REGARDING A SERIOUS UNRESOLVED, RECURRING PUBLIC SAFETY ISSUE WITH MY VEHICLE. IT IS POTENTIALLY THE FAULT OF ALEXANDRIA HYUNDAI'S SERVICE DEPARTMENT (in Alexandria, VA) WHO HAD JUST SERVICED MY VEHICLE FOR WHAT SHOULD HAVE BEEN A ROUTINE SERVICING (on May 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [XXX], I was returning to my home in Virginia from Maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "CHECK HYBRID SYSTEM - STOP SAFELY." Fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted AAA, a police officer and Uber Pet who worked together in this unsafe situation on the side of the highway to get myself and my dogs home into the Uber vehicle with only the front door opening (no power). It was over 2 hours before I was home safely It was incredibly stressful situation. The car was towed to Alexandria Hyundai and they dismissed the issue and fixed nothing. I contacted Hyundai customer service and asked for escalation and they have done nothing. I am restricted in my driving because of the severe safety risk but had to drive again on [XXX] and it occurred again on a highway INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U
