2005 Kia Sedona Transmission Problems

While driving at highway speeds (55 mph), your van suddenly makes a loud bang, jerks forward, and the engine RPMs jump above 4000 as if the transmission dropped into second gear. The check engine light points to an intake manifold or transmission sensor problem. You've replaced this sensor three times—twice with aftermarket parts and once with a genuine Kia part—but the issue returns after about 20 miles of driving, even though it temporarily works after restarting. The underlying problem may be a faulty sensor, a wiring issue, or a transmission control module malfunction that requires professional diagnosis to identify the root cause.

I WAS DRIVING DOWN THE ROAD WHEN THE CLEAR ROAD TURNED INTO BLACK ICE GOING AROUND A CORNER, I THEN GOT PULLED INTO SNOW AND THEN SIDE SWIPED A TELEPHONE POLE THAT SENT ME INTO A BOULDER BIGGER THAN MY CAR. THE IMPACT WAS AT 30MPH AND THE AIR BAGS WERE SUPPOSED TO DEPLOY BETWEEN 7 AND 10MPH. MY HEAD WHEN INTO THE WINDSHIELD 2 TIMES AND BOUNCED OFF THE STEERING WHEEL. MY WIFE SLAMMED HER HEAD OFF THE DASH AND MY DAUGHTER HAD A SEATBELT BRUISE. THE AIR BAGS NEVER DEPLOYED AND KIA HAS A SO CALLED FIX FOR THE AIRBAGS BUT ITS STILL NOT OUT OR RECALLED YET. WHEN THE AMBULANCE SHOWED UP THEY HIT THE BLACK ICE AND ALMOST SLID INTO US. ABOUT 20 TO 30 MINS AFTER THE AMBULANCE SHOWED UP THE TOWN HAD A SALT AND SAND TRUCK COME OUT AND FIX THE CORNER. ON THE WAY TO THE HOSPITAL THE EMT TOLD ME I WAS THE 5TH OR 6TH PERSON TO CRASH IN THE SAME SPOT THIS YEAR. AND THE YEAR HAD JUST BEGUN. BUT MORE IMPORTANTLY THE ENGINE WAS PUSHED BACK 2 TO 3 INCHES AND I HAVE PICS AND VIDEO OF THE DAMAGE. THE AIRBAGS COULD HAVE SAVED US A LOT OF PAIN AND SUFFERING AND HUGE HOSPITAL BILLS. *TR
