I have a new Tucson Hybrid SEL with just over 1,500 miles on it. When in 1st & 2nd gear, I'm hearing a strange noise coming from the engine, almost like a knocking kind of sound. Not sure if it's the engine or transmission. It's especially pronounced under load... going up a hill, etc. It might be my imagination, but it seems to be getting worse. I'm bringing it in to the dealer but just curious if anyone else has heard this sound. It's quite noticeable in the car but harder to pick up on video. Here is short clip.
