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.

    I think Kia should be required to fix this problem regardless of warranty coverage. It is a problem they have admitted to by releasing a new tensioner to fix it

    Had the fan belt replaced some months ago. When starting the engine all is OK. but when I put the auto in drive or reverse there is a rumbling noise until I accelerate slightly. After driving a short distance or a warm up of five minutes or so, the noise is gone. I suspect the belt material itself is making the noise until it is sufficiently warmed up and more pliable. Is this a reasonable diagnosis? Or is there a known cause?

    Excessive noise on startup when cold then goes away after the car is warmed up. Noise is increased when put in drive or when heater fan is running.

    Our timing chain broke at JUST under 50,000km, 2 years old. Initially, the engine was making a strange noise on startup that would go away and sometimes return on acceleration. No warning lights came on. Within a week, the timing chain broke and the motor blew apart. We have been waiting for a week now to hear from KIA whether they are going to honor the warranty. I'm pretty choked that a 2-year-old motor could blow apart like that - let alone that a timing chain can blow apart like that - let alone the fact that NO warning lights came on - AND, a military mechanic who stopped to try to help us with his service vehicle tried to use the code reader on the van, and NOTHING came up. Now they are suggesting that a short lag in an oil change from a YEAR ago may void the warranty. REALLY, KIA? Hope you come through on that warranty...

    My 2006 Kia Sedona makes a horrible noise only on start up, have had it to kia many times and was told this was called a rough start, also had my kia in the shop in december 2013 cause the oil light was on, when kia called me they said good news is that is not the oil pump but my engine needed to be flused $200.00 later on the way home the engine light came back on. I took my car to another shop they removed the oil pan and said the oil pump was bad and that kia never removed the pan cause the original seal was still on it.

    Dealership said 14.0 hours of labor and $1240.00 to fix, which will avoid wearing ou the guides.
