Report: Improved Timing Chain Tensioners Available to Correct Noise on Startup
Hyundai Sonata Problem
Model Years Affected: 2006, 2007, 2008, 2009, 2010
Engines Affected: 2.4L 4 Cylinder, 3.3L V6
Average Mileage: 64,188 mi (20,000 mi - 132,000 mi)
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.

Timing chain tensioner noise since 20k miles, took in dealer said 'normal'. Now it is much worse, taking it back and going to insist on the tensioner being replaced under my extended warranty. Is there any TSB number or document I can print out for the dealer to deflect the standard 'I don't want to do it' crap?

Our 2006 Sonata with 3.3 L engine has been makiing this noise for over a year. Was told last year that it had to make the noise for longer than 15 seconds before they fixed it. Did my own oil change last fall and found a lot shiny metal particals in drain pan. Mentioned this to dealer in December and was told the same thing as last year. Contacted Hyundai direct and was told it should be fixed as it is "under warranty". Taking it to dealer this Thursday (1/24) for them to check it out. We'll see what they say then.

I currently have this now and the closest Hyundai dealership to my home which is about 50 miles away says it's the timing chain tensioner and it will cost $1,500 to fix. I know there is NO WAY I could fix this myself. A mechanic I know did tell me before trying that, to try flushing the engine before having the chain tensioner replaced.

I had this issue upon start-up several years ago. This was fixed under warranty and I have not had an issue since.
