I had one of the most exciting Sonata there is. I ran it for 196K miles and no problem until a technician suggested to ad an additive due to the high mileage. He suggested One of the best in the market out of different brands which had a higher viscosity to compensate for the high mileage. That’s where I lost the engine. It broke real bad well beyond repair. It was the only car in the family so I ended up discarding it due to the cost of replacing the engine. So I still bought another Hyundai due to the quality of the product, which is very good. I wish I can find another Sonata like mine but wonder if I can find another N series. Any info would be greatly appreciated.
