NHTSA Complaint #10378837 — 2005 CHEVROLET COBALT

I WAS DRIVING ON THE HIGHWAY AT 75-80 MPH WHEN THE ENGINE SUDDENLY STOPPED. "REDUCED ENGINE SPEED" AND "ENGINE DISABLED" WARNINGS SCROLLED ACROSS THE ILLUMINATED ON THE INSTRUMENT CONTROL PANEL. AFTER PULLING OVER TO THE SHOULDER, I WAS ABLE TO RESTART THE CAR AND CONTINUE DRIVING WITHOUT FURTHER INCIDENT. PRIOR TO THIS, I NOTICED THAT THE VEHICLE'S RPMS DROPPING AND THEN NEARLY STALLING WHEN SLOWING DOWN AT TRAFFIC LIGHTS OR STOP SIGNS. I TOOK THE VEHICLE TO THE DEALER AND THEY REPLACED THE THROTTLE BODY AND ECM. THE CAR RAN FINE FOR A COUPLE OF WEEKS AND HAS JUST RECENTLY STARTED AGAIN WITH THE EARLY SYMPTOMS OF NEARLY STALLING AT STOP SIGNS AND TRAFFIC LIGHTS. I HAVE NOT YET TAKEN THE CAR BACK TO THE DEALER, BUT WHEN I CALLED THEM THEY SAID THEY PROBABLY WOULDN'T BE ABLE TO TELL ANYTHING WITHOUT SOME KIND OF ERROR MESSAGE. *TR
