This is our second one of these stoves.  Our last one lasted for 5 years before the touch quit working.  Then we bought a replacement.  Now the replacements touch buttons has also quit working.  Looking through the reviews i am not the only one with this issue.  I would have hope the new cooktop would have had upgraded boards to fix the issue but it is not the case.  the new stove was manufactured in late 2019 and the issue is still there.  I will not buy another LG cook top.  This is too bad because all my appliances and even my tv is LG.
