In April, I had my local dealer perform TSB 148 on my 2014 Cadenza. This was done in accordance with the revised TSB. Mileage was 36,635. Approximately 2000 miles after the completion of the TSB, the noise slowly started to come back. I now have 6400 miles since the TSB and on startup, the thrashing is very pronounced. I am trying to talk my Rep at the Kia Preferred Access Team but I am having difficulty getting a call back. I did miss one call, and called back 5 minutes later but could not connect.

My question is, how many folks here have had the Cam Chain Tensioner replaced but had the noise return. If you were successful, and the noise did not return, please say so and let us no how many miles you have driven the car since the work was performed. If the noise returned, how many miles did it take before you noticed it.

I just purchased a 2015 Cadenza with nearly 47K miles. I think that the last of the factory warranty expires in October, and the dealer I purchased from also provides a 90 warranty. When starting it after its been sitting for a little while, there is a rattle for a few seconds. Has there been any determination on this? Would a new tensioner resolve it? Has anyone tried using 0W40 oil? Does it get worse with age, or stay the same. It doesn't really bother me as it is, other than concern that it might lead to failure. The car that this one replaced had 220K miles (16 years old), and I am hoping to get a similar life out of this car.
