My Samsung TV, electric range, and fridge have all been repaired or replaced under warranty several times.
Currently my electric range is out of warranty and one of the burners has broken yet again.
Household appliance we got are all Siemens/Bosch (same group - BSH) and i couldn't be happier. They last a long time, are reasonably priced, available and if you go all in price-wise also got the latest and greatest and fanciest features...
10 years ago I bought a Samsung 4k TV, Bluray+Surround system, Fridge and front-load washing machine at roughly the same time.
All of them are still working.
The washing machine is flawless, despite being basically neglected most of the time.
The fridge is great so long as you don't over-crowd it.
The TV and surround system look and sound great, but the software got worse after purchase and they now work better as 'dumb' devices. HDMI CEC audio dropouts went away when I switched to Optical.
I will in the next 6-ish months be replacing the TV and surround system, but not with Samsung despite their still amazing looking TVs, I don't trust their software not to do dumb/annoying things.
Comparatively, my parents Sony TV is some 20 years old and flawless.
So yeah I didn't have a great experience.
