Long-time VW family here, currently have a 2016 Jetta and 2019 GTI, neither have had a problem but because of the pandemic and working from home both have unusually low miles, 33k for the Jetta, 16k for the GTI.
Because of the low miles, and because I'm not a fanboi of any brand, I won't discount the reliability issues others have brought up. But each car is literally generations ahead in reliability over the MK4 Jetta we had in the early '00's. It was a nice little car, but it had a myriad of small, niggling issues.
Both of the current VW's are very good commuter and road trip cars. We've driven from Austin to Chicago and Austin to Santa Fe multiple times in both and they're just great.
One thing I haven't seen mentioned, and this is just a "me" thing since I've spent so much time on the VW forums: I wouldn't buy a used GTI unless I was 100% certain it wasn't modified and then returned to stock for the sale. Or, I'd have to know the seller/history.
Note that I'm not saying that they can't take being modified, they absolutely can. The EA888 is almost like the small block Chevy when it comes to the aftermarket and being able to produce reliable horsepower.
What I am specifically saying is that 90% of the VW forum content (in my opinion) would disappear if all of the botched DIY stories were filtered out. Things as basic as "brah, I tuned specifically for 93 octane high hp and torque, but now gas is expensive so I've been using 87 and now I've got cel's all over the place."
And after years of seeing grenaded turbos from botched diy installs, screwing up intakes, Frankenstein-cutting to make intercoolers "fit", downpipes not being connected and melting a nearby wiring harness, and even one dude unscrewing a bolt in his DSG transmission thinking it was the oil drain plug, etc., from people whose "reach exceeds their grasp" ... only to have them eventually post something like "I'm returning this POS German crap-car back to stock and unloading it on Carvana!!"
Again, these can be tuned easily and reliably but be wary if the history is unknown. Or at least I would be wary.
