Assessing "reliability" between brands is very hard (and a lost cause IMO) because there's tons of things that have a large effect but are hard to measure and quantify.

Reliability variation between models > reliability variation between brands. Generally speaking cheap disposable appliance cars are cheap and disposable. OEMs put much more effort into their flagship products and the products that define their brand image.

Owner demographics have a large effect on reliability over the kind of 5+yr timeline many commenters here seem to be talking in. The wealthier the owner the better the vehicle is treated (at a statistical level, we all know one or two rich guys who never change their oil). Rich people years vs poor people years is like highway miles vs city miles. As vehicles get older they get cheaper they move down the economic ladder which tends to complicate things a little. In states with road salt wealthier people are much more likely to keep their vehicles in garages or wash them regularly.

When it comes to vehicles >8yo (or whatever the oldest banks will write a loan for at present) you see on the road is not necessarily what's reliable or what's popular. The dealership auction system tends to siphon off vehicles over a certain age and/or under a certain value to the South American (from North America) and African/Middle Eastern (from Europe) markets. This means that vehicles owned by the demographics that tend to trade in regularly (wealthier on average) will not stick around as well as the vehicles owned by people who don't or who tend to buy/sell private party (less wealthy on average). So the old vehicle you see driving around are not necessarily a 1:1 representation of what was or wasn't reliable or what was or wasn't popular back in the year they were sold. Different demographics keep vehicles for different amounts of time. People tend to get new vehicles at life milestones younger people are moving up in the world commuting, starting families and this prompts them to change vehicle more often. Grandpa bought a 'Vic in '94 and has been driving it since.

Replacement cost greatly effects a how long a vehicle is kept in service. Replacing a compact SUV is cheap compared to a 1-ton truck so at any point in time the owner of the big truck is much more likely to fix any problem that comes up rather than go looking for a replacement. Look at the 90s Fords you still see around. Ford sold a TON of Explorers yet 1st and 2nd gen Explorers are a rarity on the roads compared to F-series.

Also, just because you never see a particular make/model where you live doesn't mean they don't exist in large numbers elsewhere.

There's probably a few things I'm forgetting but people would do well to keep in mind all the things that aren't being controlled for when they read about vehicle "reliability".
