2014 Hyundai Veloster

VEHICLE STOPPED DRIVING UNDER ITS OWN POWER AFTER DRIVING FOR SEVERAL MILES ON A COUPLE OCCASIONS. USUALLY AFTER DRIVING AT ABOUT 60MPH FOR 30 MILES OR MORE. IT EITHER BOGS DOWN GIVING TIME TO PULL OF THE ROAD OR STOPS COMPLETELY AFTER TRYING TO ACCELERATE AFTER A COMPLETE STOP. VEHICLE IS GIVING A P420 ERROR CODE BUT EXHAUST TECHNICIANS SAY IT IS NOT THE CATALYTIC CONVERTER. VEHICLE WILL DRIVE AFTER EXHAUST SYSTEM HAS BEEN GIVEN TIME TO COOL. COMPRESSION IS BEIN LOST IN ONE CYLINDER AS DETERMINED BY HYUNDAI DEALERSHIP. DEALERSHIP CLAIMS A NEW ENGINE AND CONVERTER IS REQUIRED. RESULTS APPEAR TO BE THE SAME CONDITIONS AS LISTED IN SC176 FOR THE KIA SOUL 1.6L GDI ENGINE. HIGH EXHAUST GAS TEMPERATURES MAY DAMAGE THE CATALYTIC CONVERTER, POSSIBLY RESULTING IN ABNORMAL ENGINE COMBUSTION AND DAMAGE TO ONE OR MORE OF THE ENGINE'S PISTONS AND POSSIBLE PISTON CONNECTING ROD FAILURE.

WE WERE DRIVING ON THE NEW JERSEY TURNPIKE DOING ABOUT 60 OR 65 MPH AND ALL OF THE SUDDEN THE CAR STARTED MISFIRING CAR JERSEY AND STARTED VIBRATING INWAS CLOSE TO EXIT 12 SO I GOT OF EXIT 12 AND FOUND A PARKING LOT WHERE THERE WAS A PEP BOYZ AND TOWED THE CAR TO MY SISTER IN LAWS HOUSE. TOOK IT TO THE SHOP AND THEY SAID THAT THE CAR DOES NOT HAVE COMPRESSION IN CYLINDER 2 THE CAR NEVER SHOWED ANY SYMPTOMS OF ANY SORT CAR ALWAYS RAN FINE OIL CHANGED ON TIME ALWAYS CARED FOR.

CAR MAINTENANCE HAS BEEN WELL KEPT. ROAD IN DC, HIT POTHOLE SUDDENLY ENGINE STARTED TO MAKE HORRIBLE NOISE AND STALLED OUT IN THE MIDDLE OF TRAFFIC. NO TAPPING NOISE BEFORE THIS INCIDENT. ALL OF A SUDDEN METAL IN OIL AND WAS TOWED TO HYUNDAI DEALERSHIP. DEALERSHIP TOLD ME MY ENGINE SEIZED. AS A SINGLE MOM THIS IS NOT A RELIABLE OR SAFE. I WAS ONLY GOING 35MPG. IF THIS HAPPENED AT A HIGHER SPEED OR ON A HIGHWAY THIS COULD OF BEEN A FATAL INCIDENT. *TR

THE AC/HEATER BLOWER MOTOR CONTROLLER IN THIS VEHICLE AND EVERY MODEL THAT SHARES THE SAME STYLE KNOB HAS A SERIOUS DEFECT. ALONG WITH THE FIRE HAZARD THIS PRESENTS IT ALSO EFFECTS THE USE OF DEFROST WHICH CAN BE A SERIOUS ISSUE IN SOME CLIMATES AND THE SWITCH MAY FAIL COMPLETELY RENDERING THE DEFROST FUNCTIONALLY UNUSABLE. ATTACHED YOU WILL SEE IMAGES OF THE INSIDE AND OUTSIDE OF THE SWITCH IN QUESTION AS WELL AS THE CONNECTOR FOR THE SWITCH WHICH HAVE SUFFERED SERIOUS HEAT DAMAGE. THIS IS A FIRE HAZARD. HYUNDAI CHOSE TO USE THE SWITCH ITSELF AS THE CURRENT PASSING CONDUCTOR INSTEAD OF A RELAY AS USED BY MOST MANUFACTURERS. THIS DECISION IS CLEARLY REFLECTED AS A NEGLIGENT ONE WITH REGARDS TO THE STRUCTURE OF THE SWITCH AND INCORRECT GAUGE OF THE WIRING USED FOR SAID SWITCH. WITH NORMAL USE IN ANY POSITION ON THE DIAL, THIS ISSUE WILL CAUSE THE WIRING OF THE CONNECTOR, AND THE INSIDES OF THE SWITCH TO OVERHEAT. THIS IS NOT A MATTER OF FUNCTIONALITY, THIS IS A MATTER OF SAFETY. WITH THESE LOW GAUGE WIRES BEING USED FOR THIS IT POSES A SERIOUS RISK OF FIRE. PLEASE SEE THE ATTACHED PHOTOS FOR EVIDENCE OF THE SWITCH AND CONNECTOR DEFORMATION CAUSED BY OVERHEATING. PLEASE BARE IN MIND THAT THE SWITCH COMPONENTS AND CONNECTOR APPEAR TO BE MADE OF PA6, A GLASS FIBER REINFORCED NYLON WHICH IS INTENDED TO STAND UP TO A GREAT DEAL OF HEAT. ADDITIONALLY THE WIRE WRAP (PICTURED BELOW) MEANT TO PROTECT THE WIRING ON THIS CONNECTOR FROM RATTLING IS MADE OF A CLOTH/COMPOSITE MATERIAL, WITH THE ABILITY TO MELT AND CATCH FIRE. THIS ISSUE IS A CONSTANT BEING DOWN TO THE WIRING. IN MOTION, STATIONARY, OR OTHERWISE HAS NO BEARING SO LONG AS THE CLIMATE CONTROLS ARE BEING USED. THANK YOU FOR YOUR TIME.
