multiple times this has been an issue. I stepped on the break and the car essentially leaps forward typically when going up down or straight. In November 2024 it happened while going up a hill slowly and I bumped into the vehicle ahead of me. My vehicle had no damage, but the car in front of me had to get a new skid plate and my insurance doubled because of it. Since the incident in November 2024, my car has unintentionally accelerated intermittently. finally, April 2025 this happened my car started shaking jolted forward, engine revving, and then my check engine light came on then immediately contacted my local dealership and scheduled an appointment to get my car in.
