Due to several possible engine-related problems, the Check Engine Light may illuminate. If this occurs, reprogramming the computer that controls the engine should fix the problem.

RepairPal Verified Hyundai Entourage Problem Reports
If you have driven your car a few miles and experience a hesitation during acceleration, possibly accompanied by illumination of the Check Engine Light, the problem may be related to a defective front oxygen sensor. An updated sensor is available to correct this problem.
If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this problem.
Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.
If you experience difficulty getting your Entourage transmission out of the Park position, a redesigned gearshift lever is available.
