Hyundai’s Most Reliable Engines Of All Time
By JOE HINDY
10. Gamma 1.4L
The Hyundai Gamma 1.4-L Inline-4, or G4FC, is an engine that the automaker still uses on its least expensive vehicles, such as the Accent and Kia Rio.
These small and relatively slow engines, with around 100 horsepower and 100 lb-ft of torque, are better suited for city vehicles than those traveling at highway speeds.
9. 2.4L NF
While the Theta II engine was a disaster, the Hyundai 2.4-liter NF G4KC Theta I variant typically ranks high on RepairPal’s reliable engines list for its model year.
The G4KC could be found in models like the Sonata and Grandeur, though it wasn’t widely used. It could produce 162 horsepower and 164 lb-ft of torque.
8. Alpha 1.6L
One of the company’s earliest-produced engine models, the Hyundai Alpha 1.6-liter G4ED improved on its previous iteration for added reliability.
Hyundai designed the engine to be easily accessible and repairable. The company would use the engine to power vehicles like the Accent, Elantra, and Kia Rio.
7. 2.2L CRDi
The Hyundai 2.2-liter CRDi, or the D4HB, is one of the automaker’s longest-running and most reliable engines. It was first introduced in 2009 and is still used today.
This diesel engine is used in cars like the Santa Fe. While the engine has few issues, it’s known to consume oil and may need its piezo-electric injectors replaced.
6. Gamma 1.6L
Named one of the 10 best engines in the US in 2011 by Wards AutoWorld Magazine, the Hyundai Gamma 1.6L is still in production today.
Hyundai has been using variants of this engine since 2007, appearing in models like the Konda and the Kia Soul. JD Power gives 1.6L-equipped models fairly high-reliability numbers.
