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.

Most reported Hyundai problems
Excessive engine noise may be noted after a cold start. If the engine oil level is correct this type of noise is commonly caused by faulty timing chain tensioners. Our technicians tell us that revised chain tensioners are available to correct this issue.
System component failure can cause the airbag warning light to illuminate. Stored fault codes should be diagnosed to help isolate the cause of the problem. A recall for the driver's side airbag applies to 1994 & 1995 models only.
Premature timing belt failure may result in serious engine damage. When replacing a broken timing belt, it is important to inspect and possibly replace the crankshaft position sensor; it is often damaged when the timing belt breaks.
Problems with the accelerator pedal position switch may cause the Check Engine Light to illuminate; an improved switch is available to fix this problem.
Slipping of the automatic transmission and/or loss of forth gear may be caused by failure of the end clutch. Replacement of the failed clutch will be necessary to correct this issue.
A hard start or rough idle when cold may be noted. Our technicians tell us a powertrain control module software update is available to correct this concern.
Engine stalling or failure to start may indicate crankshaft angle sensor failure; Hyundai issued a recall (03V030000).
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.
The manual transmission may become difficult to shift into third gear. This is common caused by worn synchronizers. Our technicians tell us that revised synchronizers are available to correct this concern.
The motorized seat belt may chatter or become jammed in its track and not operate properly; Hyundai issued a recall for 1990 - 1994 model years that should correct this concern.
