Hi,

I have a 2016 Hyundai Tucson with about 50k miles on it. I had an oil change on 7/3. I started hearing the noise last week. It sounds like someone hitting a rock against the engine ONCE. I don’t hear the knocking while I’m driving. Also, I can only hear the noise when I start my car in my job’s underground parking garage. I don’t hear it when I start the car in front of my house etc.

The sound comes at the :10 mark

Which transmission do you have? If it’s the DCT, they make weird clicky noises sometimes, especially during state changes (engine start, reverse-to-drive, etc). It’s not an indication that anything is wrong - that’s just what they do.
