NHTSA Complaint #11415457 — 2014 CHEVROLET IMPALA

I WAS DRIVING STRAIGHT ON FREEWAY AT 70MPH WHEN "SERVICE STABILITRAK" "SERVICE TRACTION CONTROL" AND "ENGINE POWER REDUCED" SHOWED IN MY DASH AS WELL AS CHECK ENGINE LIGHT. AT THE SAME TIME THE CAR SHIFTED ITSELF TO 3RD GEAR AND REDUCED SPEED TO 40MPH WITHOUT CHANGE IN DRIVER INPUT. THIS RESULTED IN A NEAR ACCIDENT THAT WOULD HAVE BEEN FATAL. THERE WAS A 18 WHEELER RIGHT BEHIND ME WHO WAS LUCKILY PAYING ATTENTION AND DID NOT CRUSH ME WHEN MY VEHICLE DID THIS. I THEN HAD TO CONTINUE DOWN THE FREEWAY UNABLE TO GO BEYOND 50MPH OR GET OUT OF 3RD GEAR DUE TO TRACTION CONTROL MALFUNCTION. I HAD TRACTION CONTROL SET TO OFF AS I ALWAYS DO, IT'S NOT A NEEDED THING LIVING IN A DRY LOW ELEVATION ENVIRONMENT. IF I APPLIED MORE GAS THE ENGINE WOULD "BOG DOWN" AND NEARLY STALL BECAUSE THE COMPUTER WAS LIMITING SPEED AND GEAR. I NEARLY DIED TODAY BECAUSE OF POOR ENGINEERING.
