NHTSA Complaint #10683685 — 2011 CHEVROLET IMPALA

DRIVING AT APPROX 35 MPH, MY CAR SHOWED SERVICE STABILITRACK / SERVICE TRACTION CONTROL / VEHICLE IN REDUCED POWER. I DID HAVE REDUCED POWER, COULD NOT GO ANY FASTER THAN 15 OR 20 MPH. I CONTINUED DOWN THE ROAD ANOTHER BLOCK AND WITHOUT WARNING, THE CAR SHUTS DOWN WHILE GOING DOWN A SLIGHT GRADE,, WHICH CAUSE STEERING TO BECOME VERY HARD TO USE ALONG WITH LITTLE TO NO BRAKING, I ENDED UP GOING THRU A STOP SIGN AT THE BOTTOM OF THE GRADE BECAUSE OF LACK OF BRAKING POWER, LUCKILY NO VEHICLES WERE COMING, I GOT THE VEHICLE STOPPED, AND LOOKED AT THE DISPLAY, IT SAID IGNITION DISABLED, SERVICE THROTTLE. BY THE VEHICLE SHUTTING DOWN THAT IS A SAFETY ISSUE, THE VEHICLE SHOULD NEVER SHUT DOWN MAKING STEERING AND BRAKING ALMOST IMPOSSIBLE, IF IT FINDS AN ISSUE WITH THE THROTTLE, IT SHOULD JUST DISABLE THE THROTTLE SO I CAN STEER AND BRAKE WITHOUT PROBLEM. AFTER ATTEMPTING TO START THE VEHICLE A FEW TIMES WITHOUT SUCCESS, THE 4TH TIME I TRIED THE VEHICLE DID START BACK UP AND WAS ABLE TO CONTINUE TO WORK, BUT WAS DID NOT SEEM TO BE RUNNING RIGHT AND CHECK ENGINE LIGHT STAYED ON. *TR
