So I just spent 6 hours at the dealership trying to replicate the issue. You needed a cold engine and it was really hot out and a long drive, so it took a while for the engine to cool. I was finally able to replicate the issue in front of the shop foreman and service person. They were able to hear the ticking difference between the normal engine tick and the new louder tick noise. Unconvinced that it was an issue, they tried 2 different cruzes and they were unable to replicate the noise. This tells us that my car is only making the noise. They acknowledge the noise difference as shown in the video, but said they do not know what is causing the noise. They do not want to start replacing redundant parts to try and fix it. The service manager told me that if the noise gets worse then they can have a further look. The manager said that it will not affect the drivability and therefore it's fine, even though we do not know what is causing the noise. I am really not pleased with this result. My new car sounds like a POS and I have to deal with it because it's not a safety concern. Not too mention the cruze already makes terrible noises (metallic rattle at 1500rpm and bird chirp noise under the hood at idle). The other problem here is that what if there is a snowball effect, which could cause other issues down the road. I do not understand this situation or how to get it corrected. I wish it was as easy as going to another dealer, but my experiences have proven that it will not lead me to a resolution. The dealership I am currently working with is really good, but not with this situation. If you have any suggestions on how to get this situation rectified, please let me know!! Thanks again everyone, sorry it wasn't the result we were looking for.
