I wish they'd link to the actual study so we can see how they determine "reliability".

They don't get very granular, but they give a fairly detailed overview of the methodology here:
https://www.consumerreports.org/cars/car-reliability-owner-satisfaction/who-makes-the-most-reliable-cars-a7824554938/

Edit: I used to subscribe, and as a result received their surveys occasionally. They seemed pretty well done, but people are people and probably aren't always objective in their reporting.

Yeah I saw that but again it's very basic explanations...

We study 20 trouble areas, from nuisances—such as squeaky brakes and broken interior trim—to major bummers, such as potentially expensive out-of-warranty engine, transmission, EV battery, and EV charging problems. We use that information to give reliability ratings for every major mainstream model.

Where are they getting that information and how are they using it? This is important and their conclusion is incredibly counter-intuitive and refutes pretty much all other research I've seen.

Extraordinary claims require extraordinary evidence.

They send a survey to their subscribers.

The next paragraph states:

We weigh the severity of each type of problem to create a predicted reliability score for each vehicle, from 1 to 100. We use that information to give reliability ratings for every major mainstream vehicle. (The reliability rating is then combined with data collected from our track testing, as well as our owner satisfaction survey results and safety data, to calculate each test vehicle’s Overall Score.)

Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect!
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
