We remodeled our kitchen 2 years ago and replaced all appliances with LG.  I had been extremely happy until 2 months ago when one control knob cracked on the Stainless cooktop.  They are ridiculously expensive to replace, but I wanted the cooktop to look nice not cruddy with knobs missing, so I purchased it.  Two days ago my husband was cooking and informs me there are now 2 more knobs broken.  They are plastic and not manufactured to hold up to the rest of the cooktop.  Very disappointing.  Until this point I highly recommended LG appliances to everyone who saw our kitchen remodel.  I will have changed my opinion since this problem surfaced.  I included photos and when taking those, I found the last 2 knobs are also cracked in several places.  Those are burners we never use.
