Samsung is the worse. During an interview they outright said they do not have to follow American laws because the sell more outside the US than inside.
I was slowly over the year poison by my 2008 SS refrigerator. I had no idea the fridge was not staying at the proper temperature. We bought another SS because we were told the previous fridge was an economy line and the biggest fridge we could fine was another SS. Still all sorts of stomach issues continued and not knowing why I went through all sorts of tests and procedures. Then the wire to the flex drawer on my SS was cut from a bad design. I googled how to fix it because my fridge was just 4 yrs old and a month past the warranty. That is when I found a FB group for SS and learned to put in a digital thermostat in it. Turned out to be the route of all my stomach issues. My fridge never stayed at safe temps, it would climb as high as 53F in the middle of the night. not a single person would be awake keeping a door open or anything.
From this group I found LG and SS to be the worse of the worse. Most ppl have no idea that the temperature on the door does not mean that is the temperature inside the fridge. Most ppl also do not put in a digital thermostat that tracks the temperatures, they might get one of those fridge ones with the needle but that only tells you the temp at that moment when you open the door.
The other part is that not only do other brands have issues it is all about the customer service you have to deal with. GE or Kitchen Aid, Whirlpool, Bosch and such will make things right. LG and SS will blame everyone and your Uncle for the issues. They have the most sales, because they are cheap and ppl will comment on them after a month or two of buying it. Of course everything is fine at that point, and if you're lucky your good until a yr or two later. That is why they score good with CR. Which by the way is a useless site as they don't actually research anything and will not help you if you report fires started by some of those appliances.
Anyway, with my doctor's help and my Govee thermostat I got a full refund from fighting SS. I now own a Whirlpool and it keeps the fridge at safe temperatures 100% of the time.
