“Around January 30, 2023 (need to verify the exact date). My vehicle went on limp mode, the engine light went on plus an additional warning light. I was driving on highway 99 when my car started to stall. It felt like the car put itself in neutral mode. It was frightening as it happens randomly & suddenly after being able to drive 60+ mph. It wouldn’t pick up speed. Driving 5 mph. It was frightening as I was far from the exit & the vehicles behind were honking and 1 swerved, thankfully the driver was able to change lanes. …”
