Jan/2023 at 55mph, a vehicle swerved into my lane which required immediate braking. Applying the brake, the Jeep engine surged, and Jeep would not slow down. I reapplied brake and initially it didn't slow my vehicle. After re-reapplying the brakes, the Jeep responded to the braking. On Mar 28, 2023 traveling approximately 20 mph in a vehicle round-about, following a pickup truck which was two car lengths ahead of me and suddenly the pickup stopped for a pedestrian. I applied my brakes on my 2022 Jeep Wrangler and the engine surged, the Jeep sped forward, I reapplied the brake but my Jeep wouldn't stop until it crashed into the rear of the pickup. There was no damage to my Jeep but some rear bumper damage to the pickup. During both incidents the ESS (Engine Start/Stop) was disabled.
