No, not 199 recalls. I don't know what the numbering scheme is, but there have been a couple. Maybe 4 total, but 3 of them are battery (or BMS) related.
The battery fire issue is the elephant in the room. There really weren't all that many battery fires in the broader scheme of things, but from Hyundai's point of view one battery fire is one too many. For some reason there are more in Korea - my recollection is that there was only one in North America (Montreal?). I don't know the absolute number of battery fires - maybe a dozen worldwide. That's a rough guess, really. Most of the changes to try and fix this are software related - mainly to try and detect an issue before a fire occurs, and it gives a warning of some sort if there is some condition that is sufficiently abnormal.
Worst case, the software bricks the car which forces you to have the thing towed to the dealer. Getting a replacement battery is a several month process - I have no idea why it takes so long. A handful of us have gotten lemon-law buybacks simply because of how long it was taking to get the replacement battery pack. But they do eventually come through. That being said, the vast majority of people have no issue and are just driving around like normal.
If you are buying new, it will already have all outstanding recalls addressed. In addition, there is a belief that the battery fires were caused by a defect in manufacturing that has since been corrected (the original recall only applied to a range of VIN numbers - I don't recall the manufacturing dates) - a new car probably wouldn't have the issue to begin with.
