Vehicle speed control

“WHEN PULLING INTO PARKING SPACE AT A LOW SPEED (2 MPH) CAR SUDDENLY ACCELERATED EVEN THOUGH ACCELERATOR PEDAL WAS NOT BEING DEPRESSED. OPERATOR'S FOOT WAS ON BRAKE PEDAL THE ENTIRE TIME BUT CAR WOULD NOT STOP UNTIL IT HIT A PARKED VEHICLE. AT THE TIME THE CAR WAS BEING TURNED TO THE RIGHT COMING INTO THE PARKING SPACE. THERE WAS A HIGH CURB (~10 INCHES HIGH) AT THE FRONT OF THE PARKING SPACE AND A MEDIAN BUT THE CAR JUMPED OVER THIS AND STRUCK THE PARKED ON THE OTHER SIDE OF THE MEDIAN.”

Engine

“Sometimes, the car's RPM goes up to 4 and stays there as the car is unable to shift into the next gear. So, the car is not really accelerating at times when this happens. I have to pull over and turn off the car and start it again and sometimes it works correctly and at other times it doesn't. I've started to get check engine lights from time to time that point to solenoid issues. This makes driving this car very dangerous as this issue happens randomly. Thanks, [XXX]”
