2015 Cadillac Esclade two out of ten times doesn’t start.

What is your question?

Push the start button and acts like battery is dead. Let off the start button but it keeps trying to start. Glove box pops open, radio goes haywire, brake petal moves to highest position. Put in new battery, no change. Took to dealer and diagnostic showed no problem. Never know when I’m going to be stranded. $80k car five years old.

What makes this problem better or worse?

Nothing, might start then stop to do an errand, get back in car won’t start.

How long has your 2015 Cadillac Escalade had this problem?

Four months
