Sorento EX 3.5L V6

  • Automatic transmission
  • 90,000 miles

When you start the engine, you hear raffling noise for a few seconds—like grinding metal. After researching, I found the "Timing tensioner" was broken. So I replaced the whole timing chine stuff. I paid around $3000.00. But the problem was not solved. After replacing the timing chain a few days later, the same exact noise occurs when starting the engine. I brought the car to the center, it they told me that KIA remodeled "Camshaft." So I need to replace that too, which costs around $1300 -1500. I have no idea whether to replace the camshaft or not. But that was the issue. So if you have the same problem, you should also check Camshaft. That way, you can save Labor fees.
