Kia Sorento Problem Report
Kia Sorento Updated Timing Chain Tensioner to Correct Noise on Startup
If the engine is excessively noisy on startup (after the engine has been off for several hours) and the noise lasts more than four or five seconds, turn off the engine and check for correct engine oil level. If the oil level is correct, the noise may be caused by the timing chain tensioner. Kia released an updated timing chain tensioner to solve this problem.
