While driving on my lunch hour on January 14,2025 on busy street my car slowed down almost to a complete stop and I lost power and acceleration. My engine light came on and I had to pull off the road at a very slow speed. It was almost like I lost power in my gas pedal. It was pretty scary because it was over the lunch hour and it was busy. This could have been bad had I not been on the right lane to be able to pull off to a side street. I was concerned about being rear ended due to my car slowing down so fast and I had very little acceleration when pushing on the gas pedal.
