This Consumer Reports topic is literally a hot and very super opinionated topic. They have built themselves as either a trustworthy and reputable company for ignorant non-car people who doesn't know much about cars OR they basically make themselves look like fools and uneducated to people who better understands cars and can differentiate cars and car brands from its pros and cons.
Somehow, in this 2021 "Predicted Reliability" list, we are missing few brands. However, from personal experience and going through forums, reliability comes from how frequent the owners maintain their vehicles. Its honestly astonishing that we are using reliability for technology in cars when all we need is cars to get us from Point A to Point B. Technology in vehicles is honestly a first-world problem, and is considered creature comfort. Sure, we all have our opinions of certain vehicles and brands, but honestly, how well do most owners maintain their vehicles mechanically?
For those who disagree with me, I'm okay with that. But for reliability standpoints, technology should play a smaller and insignificant role, unless its a full blown EV like Tesla, where mostly its customers are tech geeks.
If a vehicle fails to get you from A to B and its very brand new, then there's reliability issues. If a vehicle does get you from A to B, but your music or gigantic computer screen HU doesn't work, then its a first-world issue.
