KIA REPLACED MY ENGINE TWICE, DUE TO OIL CONSUMPTION. A MONTH AFTER THE FIRST ENGINE REPLACEMENT, I HAD THE SAME PROBLEMS.. SMOKE COMING OUT OF EXHAUST, LOSS OF POWER, STALLING AND OIL CONSUMPTION. I WAS IN AND OUT OF KIA'S SERVICE DEPARTMENT. THEY TOLD ME NOTHING WAS WRONG! I MOVED FROM CO TO NE, MY HUSBAND AND I HAD TO ADD OIL EVERY 100 MILES, WITH SMOKE COMING OUT OF EXHAUST AND STALLING. LINCOLN NE KIA FOUND AN OIL LEAK AT THE EXHAUST MANIFOLD RIGHT AWAY! KIA INSTRUCTS THEN TO REPLACE MY ENGINE AGAIN! ONCE THEY REPLACED ENGINE, THEY STILL SAW THE LEAK AT THE EXHAUST MANIFOLD WITH RESULTED IN MORE GUESSING AND PARTS. THE DAY AFTER I PICKED IT UP, MY HUSBAND AND I WENT OUT TO DINNER AND MY SORENTO DIED IN THE MIDDLE OF THE ROAD. RIGHT AWAY CALLED AND GOT IT BACK IN. AT FIRST THEY COULD NOT DUPLICATE, HOWEVER AFTER TAKING IT 50 MILES, IT DIED 3 TIMES. THEY STILL CAN'T FIND ANYTHING, BUT FEEL IT MAY BE THE THROTTLE BODY. THEY PUT A USED ONE ON AND HAVE ME DRIVE IT A FEW WEEKS, IT DIDN'T DIE DURING THAT TIME, SO THEY ORDERED A NEW ONE AND INSTALLED. A MONTH LATER I DRIVE TO CO, I BREAK DOWN, IT'S TOWED BACK AND KIA CAN'T FIND ANYTHING. I DRIVE IT AND IT DIES 1/2 DOZEN MORE TIMES, EACH TIME I TAKE IT RIGHT IN, BUT THE CODE HAS CLEARED AND THEY CAN'T FIND ANYTHING! FINALLY, IT DOES AND THE LIGHT STAYS ON, IT SHOWS IT'S THE MAP SENSOR. KIA HAS A SPECIALIST COME OUT TO INSTALL THAT AND INSPECT MY CAR. THEY SAY IT'S FIXED AND SAFE. I DRIVE TO CO ON 9/22/17, 2 MONTH
