I always wonder about these surveys, but only because I can never relate.
For example:
I've owned Teslas (10) and Alfas (9), both since 2018. I've logged many, many more miles on the Alfas than on any Tesla with exception of the one Tesla we have left that's actually holding up extremely well... I think because it's a newer, SIMPLER Tesla (2023 SR3).
But, I've had WAY more problems with Teslas than any Alfa... as in NO problems with Alfa except 2 Giulia QVs needing fuel pumps (both 2017s) and my 2022 Giulia QV needing a super simple purge valve. Mind you the fuel pumps nor the purge valve ever left me stranded. I can't say the same for our P85D (stranded 3 times), S90D (stranded twice), 2020 M3P (stranded twice), 2021 SR+ (stranded once).
My Tesla problems are a long laundry list, so long that I can't remember them all... from mechanical failures, software failures, and simpler build quality failures such as I once had a passenger that couldn't get out because the rear left door on my LRRWD 3 wouldn't open from the inside thanks to the door-switch connector just "coming loose" behind the door panel (that's dangerous).
And I can say the same for VW as compared to other brands on this list that I've owned.
Example: My 2010 Jetta TDI has over 200,000 miles on it and has never needed anything but an alternator... and THAT's because service screwed up, so the replacement cost was on them. The damned thing is still on the original brake pads and rotors, though it's FINALLY time for a set of pads (the rotors look fine lol).
And that's not the only VAG product I've owned that has been maintenance/worry/trouble free.
Maybe I'm (people like us on the forums) just more attentive to my cars than the majority of people who just drive and drive and drive... never paying attention to anything until something breaks.
