Dashboard Lights Flickering After Battery Replacement - 2021 Hyundai Sonata
David Smith · · 3 replies
Just replaced the battery on my 2021 Sonata (picked up from Canadian Tire, about CAD 180). Since then, dashboard lights flicker randomly when idling. I thought maybe it’s the battery not fully charged yet, but it's been a week. Could it be alternator or something else?

Could be loose battery terminals or bad ground connections - double check tightness.

Alternator might be going bad if voltage is fluctuating - test with a multimeter.

Bring it back to CT if under warranty; sometimes new batteries have issues.
