I WAS DRIVING DOWN THE INTERSTATE ON MY WAY HOME TO KNOXVILLE FROM ATHENS, TN, AND I HEARD MY CAR MAKE A FUNNY NOISE, AND THEN I HEARD A LOUD NOISE, AND THE ENGINE BEGAN TO SMOKE, I PULLED OVER OFF OF THE INTERSTATE ONTO AN EXIT AND THEN THE CAR BASICALLY DIED WHEN I MADE IT TO THE SIDE OF THE ROAD. THE SMOKE WAS WHITE AT FIRST, BUT THEN IT TURNED BLACK SO WE RAN FROM THE CAR. THE CAR PROCEEDED TO CATCH ON FIRE AND BY THE TIME THE FIRE DEPARTMENT ARRIVED IT WAS TOO LATE. I HAD A LOT OF CLOTHING AND PERSONAL ITEMS IN MY CAR, AND MY BOYFRIEND'S LAPTOP AND REALLY EXPENSIVE TEXTBOOKS WERE IN THE CAR AS WELL. THE CAR IS COMPLETELY BURNED EXCEPT FOR PARTS OF THE TRUNK AND THERE WAS NOTHING THAT WAS SALVAGEABLE. I WAS LOOKING ONLINE AND FOUND OUT THAT MY CAR HAS BEEN RECALLED BECAUSE OF FIRES, BUT I HAD NO IDEA BECAUSE I BOUGHT THE CAR TWO MONTHS AFTER THE RECALL WAS ANNOUNCED. IT DOESN'T REALLY MATTER THOUGH, BECAUSE THERE IS NO REMEDY FOR THE PROBLEM. I NOW HAVE NO CAR AND I AM A COLLEGE STUDENT AND I NEED A CAR SO I DON'T KNOW WHAT TO DO. I'M NOT SURE HOW TO GO ABOUT CONTACTING THE MANUFACTURER ABOUT MY PROBLEM. I AM VERY UPSET THAT THIS HAS HAPPENED, AND IT WOULD BE REALLY NICE IF SOMEONE COULD HELP ME FIX THIS. *TR

SO WE WENT OUTSIDE TO INVESTIGATE THE PROBLEM AND SAW SMOKE POURING OUT FROM UNDER THE HOOD AS IF THERE WAS A FIRE CONTAINED UNDER THE HOOD. SO WE CALLED 911 AND SUDDENLY WE HEARD A LOUD POP AND SAW FLAMES ON THE HOOD. WE PROCEEDED TO GET A WATER HOSE TO POUR WATER ON THE CAR UNTIL FINALLY THE FIREMEN ARRIVED. THE CAR STILL REMAINS IN FRONT OF HER MOTHERS HOUSE, IF ANYONE WOULD LIKE TO TAKE A LOOK AT THE CAR. THE FIREMEN DEEMED IT TO BE A TOTAL LOSS. I WOULD LIKE ANY INFORMATION FOR RECALLS ON THIS MAKE AND MODEL. *TR
General Motors is recalling certain model year 2004-2008 Chevrolet Aveo vehicles equipped with daytime running lights (DRL). In the affected vehicles, there may be heat generated within the DRL module located in the center console in the instrument panel, which could melt the DRL module.
Consequence & remedy
Consequence: If the DRL module melts due to the heat generation, it could cause a vehicle fire.
Remedy: GM will notify owners, and dealers will install a revised DRL module, inspect the wiring connector for heat damage, and clean the DRL circuit grounds. Owners were sent interim notices on August 14, 2014. The recall began on February 6, 2015. Owners may contact General Motors customer service at 1-800-222-1020 (Chevrolet). General Motors recall number for this campaign is 14236.
ON CERTAIN PASSENGER VEHICLES, THE REAR SAFETY BELT CAN BECOME TWISTED.
Consequence & remedy
Consequence: IF THIS OCCURS THE SAFETY BELT RETRACTOR MAY LOCK IN POSITION SO THAT THE BELT CANNOT BE USED. IN THE EVENT OF A VEHICLE CRASH, PERSONAL INJURY TO THE SEAT OCCUPANT COULD OCCUR.
Remedy: DEALERS WILL INSTALL A SAFETY BELT WEBBING GUIDE TO PREVENT THE BELT FROM TWISTING. THE RECALL BEGAN ON OCTOBER 15, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438. VEHICLE OWNERS LOCATED IN GUAM SHOULD CONTACT GM CUSTOMER ASSISTANCE AT 1-671-648-8453.
