Noticed that the cruise control would disengage randomly when activated. I checked the function of the brake lights at night and found that the brake lights would turn themselves on randomly with zero brake input, disengaging the cruise control. In this state, depressing the brake pedal more than around 30-40% would turn the brake lights off, even with the brake pedal fully pressed. Furthermore, with the brake pedal pressed to a moderate level, the cruise control is able to be engaged, even with obvious brake pressure being applied. This defeats the cruise control disengagement feature and the cruise control system will fight against the braking system to maintain speed instead of turning itself off as it seems to rely solely on the brake lights for the automatic disengagement. This issue is quite dangerous as this seems to happen quite often with the brake lights, but I cannot find any sort of consistent scenario that causes these issues to occur.

The gas pedal would stick and the car would not decelerate when removing pressure from it. This happened a couple of times on separate days but would unstick and decelerate fairly quickly. Then today the gas pedal not only became stuck but it accelerated and I had to hit the brakes to get it to stop accelerating.

A faint noise was heard and I pulled the vehicle over to the side of road walked around the entire vehicle looking to see if anything stood out, assessed the tires, engine and nothing appeared to be wrong. I proceeded to get on the ramp on and as I went through the toll booth driving around 40 mph, the car accelerated to a speed of about 87 mph, the steering could not be controlled it was almost as if it was in a locked position. Once the vehicle took off at the high speed, it then came almost to a complete stop. The sound of the engine was revving but the speed was not supporting the sound. I proceeded to brake, use the accelerator and was going back and forth between the two functions but neither would work. Scared to go into the flow of heavy traffic, I placed the vehicle in neutral which allowed me to roll down the ramp and onto the shoulder. I then turned the vehicle off and let it sit and attempted to turn it back on to remove it more out of the driving lane, but the vehicle would not move
