2021 Hyundai Sonata - Loud engine

excessive engine lifter noise when starting untill 3 minutes warmup

Good thing it’s under warranty,

What does the dealer say?


Wanna bet the dealer will say “they all do that”?

That’s a sucker bet. To the OP: If you do, in fact, hear that line, insist on driving another 2021 Sonata to see for yourself because I call “Bull” in advance.

Some of these late model engines make a lot of noise during a cold start, particularly the turbo charged engines. There is an emissions system valve that clatters, I have not had to investigate the source of the noise. Also vacuum pumps can make some noise during start-up.

Keeping the hood closed usually solves the noise problem.
