2012 Sonata Limited, 4 cylinder, at 89000 miles. Recently, I’m hearing a sound like a bike chain when I accelerate, not always, and maybe for a second or less. It’s very hard to record a video. I sometimes hear something similar when I’m starting the car, so I will try to record it. Do you think it may have something to do with the timing chain or tensioner? The car has been maintained very well, and has never had low oil. Thanks.
