What 329 owners told NHTSA about the 2021 Kia Telluride

On cold mornings when the temperature falls below thirty degrees, the car emits a loud screeching noise from the area of the throttle body. I had the belts and pulleys checked at my last oil change (two weeks ago) and they were fine. It it’s distinctly coming from the area of the air intake and throttle body. The high pitched squeal will last for about 10 seconds and stop. By the time the vehicle gets to the dealer, it has warmed up or the temperature has gone above 30.

As I started the car, it began to shake and shudder while idling. And the check engine light turned on. I could smell the unburied gas inside the car.

021 KIA TELLURIDE, FEBRUARY 13, 2021. TEMPERATURES ARE SINGLE DIGITS OR BELOW AND GOT WORSE AS THE WEEK WENT ON. STARTED THE ENGINE AND A LOUD SQUEAL OR WHISTLING NOISE CAME FROM THE TOP OF THE ENGINE. LAST ABOUT 30 SECONDS THEN SLOWLY STOPS. ENGINE ALSO STARTS TO SOUND LIKE IT HAS MORE POWER ONCE NOISE STOPS. BEEN GOING ON FOR THE LAST 8 DAYS. BELTS AND PULLEYS SEEM TO BE WORKING FINE AND CANNOT SEE ANY ISSUES. SOUND LIKE IT IS COMING FROM UNDER THE ENGINE COVER BUT DO NOT WANT TO REMOVE COVER CAUSE TOO COLD AND DO NOT WANT TO JEOPARDIZE WARRANTY STIPULATIONS. CONTACTED MIDWEST KIA IN WICHITA, KANSAS. SENT THEM A VIDEO AND THEY THINK IT IS A VACUUM LEAK OF SOME KIND. MIDWEST KIA SAID THEY CANNOT REPORT IT TO KIA UNTIL THEY CAN SEE THE CAR BUT WE ARE 2 HOURS AWAY AND CANNOT GET OFF WORK TO TAKE IT AND NEED OUR CAR FOR WORK. I OWN A MORTUARY AND HAVE FUNERALS AND MY WIFE IS A TEACHER AND CANNOT GET SUBSTITUTES DO TO COVID. I SAID BASED ON MY RESEARCH IT SOUNDS LIKE INTAKE MANIFOLD. ON THE KIA FORUMS, MANY PEOPLE EXPERIENCING THESE VERY COLD TEMPS ARE EXPERIENCING THE SAME NOISE AND ENCOURAGED ME TO REPORT THE ISSUE. I FEEL IT IS COLD RELATED AND HOPE KIA LOOKS INTO THIS PROBLEM. THIS ONLY HAPPENS WHEN THE CAR HAS BEEN SITTING FOR SEVERAL HOURS. IF WE USE IT OFF AND ON WITHOUT SITTING TOO LONG THE NOISE DOES NOT HAPPEN. CAR RUNS GREAT ONCE THE NOISE STOPS.

MY ENGINE LIGHT CAME ON ON THE FIRST COLD MORNING. WHEN THE ENGINE LIGHT CAME ON, IT STARTED SPITTING AND SPUTTERING AND IDLED FUNNY. I SHUT IT OFF.
