Car reliability can vary so much. Some vendors have a deserved reputation for overall quality (Toyota) where issues are usually the exception (accepting the fact that issues can always happen). Others used to have terrible reputations, but are much better now (most of the Korean brands). Some have varying QA issues, depending on model, shifting suppliers, factory, etc (GM, Stellantis). Some can mostly be reliable, but when they do break it’s expensive (VW). Sometimes the car vendor is good, but the dealer you’re at can make all the difference.

That being said, you’ll always meet somebody burned by a particular vendor (or their dealer), then swear off them forever. We’re also going through a huge shift in the market with the rise of electrification and China. In some ways electric cars can me even more reliable with fewer moving parts. In other ways the software matters more and batteries replacements can be even more expensive than a new engine in a traditional car.
