The 1.0 T-GDi uses a timing chain to manage valve timing. In some cases, the timing chain tensioner may fail or the chain itself may stretch prematurely, causing improper timing.
: This is the most critical common fault. The timing chain tensioners and guide rails can wear prematurely, often between 40,000 to 60,000 km (approx. 25,000–37,000 miles). hyundai 10 tgdi engine problems

The 1.0 T-GDi engine is a compact, three-cylinder turbocharged gasoline engine that produces between 118 horsepower and 138 horsepower, depending on the application. It features a range of innovative technologies, including a turbocharger, direct fuel injection, and a variable valve timing system. The engine is designed to provide excellent performance, fuel efficiency, and low emissions, making it an attractive option for compact cars and crossovers. : The electronically-controlled wastegate actuator
: The electronically-controlled wastegate actuator, designed to improve fuel efficiency and throttle response, has proven prone to failure. When it fails, the ECU enters a protective "limp mode" with significantly reduced power, often accompanied by a check engine light.
These are cheap to fix but incredibly annoying because they fail without warning.
