ENGINE

The problem occurred while the engine was on, but I was idle in the drive thru of a local pharmacy. The car had been placed in park, but engine still running while waiting at the window. Suddenly, the car began to shake and multiple indicator lights illuminated then the car completely died. No indicator light was illuminated before this issue. I had driven the car on the interstate to and from a doctor’s appointment in a different part of town that morning with no discernible issues. The car smelled strongly of gas. I was able to restart the car to move it to a safe location for towing, but the engine struggled to start and the car continued to shake violently and more gas smell came from the car. It was turned off as soon as possible and it is now at the dealership for diagnostics and repair. There was a recent recall on my vehicle for a faulty high-pressure fuel pump. My car did not have a check engine light on and did not display the appropriate code to have the fuel pump replaced, so I only received a software update. Because the issue with the recent recall was sudden loss of power that could potentially cause a wreck, I feel that this issue is likely related to the same fuel pump problem but was missed under the previous guidance for repair. In this case, I was lucky it happened while sitting still instead of while I was on a major interstate, or I could have been seriously injured.
