Our 2018 Elantra has a fairly loud engine area whine when starting. You can also hear it quieter during some accelerations. Here is what we have had tested / diagnosed.
Yesterday I had a repair shop check the following based on other posts here. Some of the items the mechanic said weren't relevant or not relevant on this model. All pulleys spun freely though.
They DID say the alternator was testing high at 15.1 and battery was below 10.8, like at 9. I have a separate post about that here: https://www.thehyundaiforums.com/threads/2018-elantra-battery-issue-auto-shops-disagree.7857/ (In essence once show said the alternator is fine and the other said it is not. I do not know if the alternator could be involved with the whine, but they think it's coming more from the transmission area.)
So do you think this is a bad pump related to the transmission or what's my next step?
Thanks a million!
- This happens regardless of warm or cold temps outside.
- This happens even after the car has been started a few times and driven around, meaning engine isn't cold.

- idler pulley
- tensioner pulley
- crank and ac pulleys
- timing belt cover
- power steering pump, reserve tank
- oil pump pressure regulator spring
