NHTSA Complaint #10671873 — 2005 CHEVROLET COBALT

THE VEHICLE WILL PERIODICALLY JERK/HICCUP AT RANDOM WHILE DRIVING. ON JANUARY 8, 2015 WHILE TRAVELING ON THE EXPRESSWAY, THE VEHICLE BEGAN TO RANDOMLY SPUTTER/JERK/HICCUP. THE VEHICLE DID NOT LOOSE POWER, OR WAS THERE ANY INDICATION FROM DASH BOARD ICONS OF ANY MALFUNCTION. THERE WAS NOT ANY VISIBLE WARNINGS SIGNS TO ALERT A FAULTY SYSTEM. THIS HAS OCCURRED PREVIOUSLY, WHILE TRAVELING THROUGHOUT THE CITY AT SPEEDS OF 25-45 MPH. DURING THE MOST RECENT INCIDENT, TRAVELING SPEEDS VARIED FROM 50-70 MPH ON THE EXPRESSWAY. THIS PARTICULAR INSTANCE I WAS DRIVING A 60 MILE TRIP AND THIS JERKING OCCURRED 7-10 TIMES. THE FIRST TIME THIS OCCURRED WAS PROBABLY 1.5 YEARS AGO. THE VEHICLE WAS TAKEN TO A MECHANIC AFTER THE FIRST INSTANCE, WITHOUT ANYTHING BEING DETECTED OR A DIAGNOSIS. THE ISSUE IS PROGRESSIVELY WORSENING. IT IS BEGINNING TO HAPPEN MORE FREQUENTLY. LAST WEEK, OF THE 4 DAYS OF TRAVEL ON THE EXPRESSWAY, THE JERKING OCCURRED 3 OF THOSE DAYS. INITIALLY, I FELT, THIS WAS ASSOCIATED TO THE COLD AND WEATHER/TEMPERATURE, BUT THIS HAS ALSO OCCURRED IN WARMER MONTHS. THIS IS A DEFINITE SAFETY ISSUE, AS IT RELATES TO MYSELF, AND OTHERS TRAVELING IN MY VICINITY. *TR
