Kia and Hyundai don't have good reputations because of the build quality of their engines. Their poor quality piston rings means the engine eats itself. They've had to recall basically every engine they've produced in the past decade.
- abawany 4y agoYep, not to mention the recent scandal with car security (keywords: kia, usb cable) because they cheaped out and didn't include security keys until 2019.
- Grazester 4y agoYeah I was like wasn't there some issue with some of their engines. I think they have still come a long way since the early 90's. My mother owner one. Brand new off the show room in 1991 and the thing broke down at least once a month. Besides that the interior started falling apart right away(handles breaking, windows that wouldn't go up, etc) That was the shortest period she ever owned a car. She traded it in for a Nissan. If Lemon laws existed in that country then she would have had a case.
- arein3 4y agoThose kia/hyundai engines with issues (theta ii) are based on mitsubishi engine (4b11t) that don't have any issues. I think the issue was added gas recirculation, which made the engine run hotter and causing a negative feedback loop ending in piston rings getting clogged with burnt oil and scraping the cylinder walls.
- ok123456 4y agoSo it was caused by a GDI injection system being bolted on to an engine that was designed to be port injected?
