Our range is the same stove but one model year newer it started out the front burners would take 2 or 3 times pressing to turn on then it became worse even sometimes staying on not shutting off. This started when it was 16-18 months old when i called lg customer support they told me it was out of warranty i would have to pay for the repair.
At that time i purchased 3 appliances with the lg label and also own 2 tv,s.
This is a known problem and recalled on the past years model. I feel any safety issue this age should be a covered item
