Other Fuel System problem #1

The vehicle accelerate on its own accord, despite no foot or pressure to the accelerator, even going uphill and including after braking. For example, ona flat road, I stepped on the brakes and began to decelerate, I released the brake and the vehicle immediately began to accelerate forward at a high speed. I had to slam the brakes to prevent further movement. This is one of many instances, the most common of which is acceleration upwards of 10-15mph after the accelerator is released. It appears as if the accelerator remains pressed forward, I can feel the accelerator move back into place significantly later than when I remove my foot. I fear for my life and safety, and that of others. The vehicle is available upon request. I have not gone to a dealer or service center. The vehicle has not been inspected, but I have read similar reports online. There were no warning lamps or messages, but the issues began October 2022, and have increased in frequency since.
