Help! Genesis Coupe 3.8L 2010 won’t start

[Bunnie]

Hoping someone can help. My car was working perfectly fine but decided last night to not turn over. Wondering if it’s an electrical issue? Battery Is new and a boost had no effect. The dashboard lights started lighting up alternating parts - gauges would come on, then off, then stereo would light up and go off. It was like my car was having a seizure. Some clicking sound that did not correspond to the lights flickering. Locked it and the tail lights flashed like normal. Not sure what’s up. Any help would be appreciated.

Check the other ends of the cables for a good connection. Often the battery end is nice and clean but the other end is corroded.
