Report: Updated Timing Chain Tensioner to Correct Noise on Startup
Kia Sedona Problem
Engines Affected: 3.5L V6, 3.8L V6
Average Mileage: 75,104 mi (16,000 mi - 140,000 mi)
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

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.

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?

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

loud whistling sound from left side by tensioner during startup and rainy days due to the humidity. beginning to last longer.
we were unaware of the tensioner problem untill now i own a 08 sedona (still paying on ) and our tensioner failed which caused our timing chain to become loose and break things which all the peices then went all over my engine and a clog so we ended up with low oil presure which none of our gages or lights notifed us of .. we are at a loss we bought the sedona used from a non kia dealership and were unaware of the 60000 mile timing chain we always did our oil changes ourselfs and any other upkeep .. currently trying to get it fixed

Vehicle was brought in for noise at start up. Dealer refused to fix it and said it was no big deal since the noise went away after pressure built up. Noise continuously got louder and Kia kept refusing to fix it. Lo and behold once the warranty ran out they offered to fix it for $1400. Kia scammed their consumers. I contacted Kia corporate and they basically told me to go to hell
