I like fast sedans and find the Giulia to be one of the few really attractive cars sold these days, so when the high-end Quadrifoglio version came to the States I put my misgivings about Alfas aside long enough to strongly consider one as my last ICE car. I came to my senses after at least two of the prominent reviews at release described going through multiple vehicles as their initial review cars died. Car and Driver's 40,000-Mile Wrap-Up of their experience with the car (https://www.caranddriver.com/reviews/a23145269/alfa-romeo-gi...) said the QF "broke their heart" and lists a litany of issues, with the car out of commission for 80 days out of the 14 months they spent with it. They did say the car's an absolute blast to drive when it actually works, at least.

Modern Alfas are about as reliable as german cars these days, so reliability issues are more myth than fact. That being said, German cars aren't as reliable as Japanese cars.

The real problem isn't reliability but shitty dealer networks. Alfa have a knack for finding dealership networks that think it's great fun to have them in the showroom to pull people in, but aren't terribly interested in selling them or doing a good job servicing them.

My tip is to never use the dealership for servicing your vehicles (of any brand). Find a garage that has competent people, and who have respect for the work, and then pick whatever cars they are competent to work on. You don't want to spend a lot of money on a car only to have a bunch of underpaid teenagers who can only follow a manual work on your car.
