2017 Chevrolet Malibu Electronic Stability Control Esc Problems

(accelerator pedal) all of a sudden my car started to stall... Right in the midst of me driving .. No matter what speed im driving.

CAR WON'T START AND THEN GET A MESSAGE SAYING STABILITRAK. CAR HAS UNDER 60,000 MILES ON IT.

SEVERAL TIMES IN THE PAST MONTH OR SO MY CAR HAS DISPLAYED A WARNING THAT SAYS ENGINE POWER REDUCED, AND EVEN IF YOU'RE GOING HIGHWAY SPEED, WILL REDUCE YOUR SPEED DOWN TO AROUND 20 MPH. THE FIRST TIME IT HAPPENED, IT WAS AROUND 6PM IN BUSY TRAFFIC ON THE HIGHWAY, ALMOST CAUSING ME TO WRECK. IT STOPPED HAPPENING FOR A WHILE, BUT NOW IT HAS DONE IT OVER 20 TIMES IN THE PAST 48 HOURS. IT ONLY HAPPENS WHEN YOUR VEHICLE IS IN MOTION.

WHILE TRYING TO ACCELERATE DOWN THE ON-RAMP ONTO A HIGHWAY ALL OF A SUDDEN I LOST POWER AND COULD NOT EXCEED 40MPH. I ALMOST GOT SIDESWIPED WHILE TRYING TO MERGE INTO TRAFFIC BUT COULDN'T GAIN SPEED. BEFORE ABRUPTLY PULLING ONTO THE SHOULDER THE ANTI-SKID AND CHECK ENGINE LIGHTS CAME ON ALONG WITH A DASH WARNING THAT STATED :"ENGINE POWER REDUCED". I TOOK IT TO A VENDOR WHO SEARCHED THE CODE MY CAR PRODUCED AND IT WAS "P2138", WHICH IS "THROTTLE/PEDAL POSITION SENSOR/ SWITCH D/ E VOLTAGE CORRELATION". I SEARCHED THIS ISSUE ONLINE TO FIND A TON OF SIMILAR IF NOT THE EXACT SAME ISSUES WITH OTHER CHEVY MALIBUS.THIS IS A VERY DANGEROUS ISSUE! I COULD HAVE BEEN SERIOUSLY INJURED OR KILLED.

After putting the vehicle in park, and the vehicle is stationary, the p on the shifter lights up that it is in park, the screen reads that is is in park, and the car is parked and not moving. After pressing the engine button to turn the car off, a warning pops up on the screen saying 'shift to park!' even though the car is in park.
