The 1.3-liter 12-valve Hyundai G4EH engine was produced in Korea from 1994 to 2005 and was installed on the first two generations of the Accent model and the European versions of the Getz before restyling.
The first modifications of the engine with distributed fuel injection developed 60 and 75 hp, then a more powerful version of the 85 hp engine appeared on the second generation Accent.
Alpha family: G4EA, G4EH, G4EE, G4EB, G4EC, G4ER, G4EK, G4ED.

The engine was installed on:
- Hyundai Accent 1 (X3) in 1994 – 1999, Accent 2 (LC) in 1999 – 2005;
- Hyundai Getz 1 (TB) in 2002 – 2005.
Disadvantages of the Hyundai G4EH engine
- This is a fairly reliable motor and the main complaints are related to its unstable operation. Causes are usually clogged injectors, contamination of the throttle assembly or idle speed controller, as well as contacts on candles, cracked ignition coils and high-voltage wires.
- The units of this family are distinguished by a not very long resource of hydraulic lifters, they often begin to knock even before 80,000 km of run, and many owners change them. The cause may be a drop in lubricant pressure due to wear on the oil pump plunger.
- The timing belt is designed for 60 or 90 thousand kilometers, depending on the version of the unit, but very often it bursts earlier and usually this ends with a bend in the valves. When replacing the belt, it is better to install a new water pump, because its resource is also small.
- After 200,000 km, the power unit can consume up to one liter of oil per 1000 km. The culprits are usually hardened valve stem seals and need to be replaced. The reason may be stuck rings, but then it’s really possible to get by with just decarbonizing.
- The weak points of this motor include an unreliable starter, short-lived engine mounts, regular lubricant leaks and the appearance of a Check Engine due to a burnt muffler corrugation. Also, the emergency shutdown of the fuel supply is very often triggered here.
