I was driving into work on a major road (about 45 mph) when my 2023 Hyundai Sonata stopped accelerating and my engine gave out. Initially I thought I was accidentally pressing on my break pedal but when I realized I wasnt pressing the break, I had just enough time to turn on my hazards and get out of traffic and onto the shoulder of the road. I was stuck between a main exit and the major road. My battery, oil, and engine lights came on (no service lights had been on prior to this incident) and my car was just very slowly rolling before it automatically engaged my parking break — which makes me fearful of what would have happened if I had still been in busy traffic. I could gotten very badly rear-ended. My car only has just over 5600 miles and I never had any issues with it before and kept up with the general maintenance. I attempted to restart my car to no avail and about 30 minutes later I was able to restart my car but there was a very strong vapor smell in the cabin of my car. I got my car towed to a dealership and was informed one of my fuel injectors was misfiring/gone bad — similar to many other incidents on this site. I asked the dealership if they were able to view the state of my other fuel injectors and was told they were unable to do that, so I am unsure if other fuel injectors will go bad in the future.
