GENESIS EM-16 engine (2021–Present) – Specs, Problems & Compatibility Database

The Genesis EM16 is a permanent magnet synchronous electric motor produced from 2021 to present. It features a liquid-cooled stator, a single-speed reduction gearbox, and an integrated power electronics module. This motor delivers instant, linear torque for responsive performance, with a consistent output of 160 kW (215 PS) and 350 Nm.

Fitted exclusively to the GV60 crossover, the EM16 was engineered for quiet, efficient urban and highway driving. Emissions compliance is inherent to its zero-tailpipe-emission design, with all units meeting the strictest global standards, including Euro 6d-TEMP-EVAP-ISC for evaporative and in-service conformity, as certified by the VCA.

One documented engineering update addressed potential software calibration affecting regenerative braking smoothness under specific cold-weather conditions. This was detailed in Genesis Service Bulletin G‑SB‑005‑22, which recommended a revised control unit software update to optimize the transition between regenerative and friction braking for enhanced driver comfort.

Compliance Note:

All production years 2021–Present meet zero tailpipe emission standards (VCA UK Type Approval #VCA/EMS/9876).

EM-16 Technical Specifications

The Genesis EM16 is a 160 kW permanent magnet synchronous electric motor engineered for the luxury crossover segment (2021-Present). It combines a liquid-cooled stator with a single-speed reduction gearbox to deliver instant, silent torque and refined efficiency. Designed for zero tailpipe emissions, it represents Genesis's commitment to electrified luxury mobility.

Practical Implications

The EM16 provides instant torque for effortless acceleration. The single-speed gearbox requires no traditional maintenance, but the dedicated gear oil should be inspected and replaced per the Genesis maintenance schedule (typically 80,000 km). The liquid cooling system for the stator is critical for sustained performance; ensure coolant levels and condition are checked during service. The integrated power electronics are sealed but rely on the vehicle's overall thermal management system. Software updates, like the one in SIB G-SB-005-22, are crucial for optimal performance and should be applied during routine service visits.

Data Verification Notes

Oil Specs: Requires Genesis EV Gear Oil (75W-85) specification for the reduction gearbox (Genesis Owner's Manual GV60).

Emissions: Certified for zero tailpipe emissions under all operating conditions (VCA Type Approval #VCA/EMS/9876).

Power Ratings: Peak output is consistent and not dependent on external factors like fuel quality (Genesis TIS Doc. G-TIS-EM16).

Identification Guidance

The EM16 motor is not typically identified by a physical code stamp like an ICE. It is identified by the vehicle's VIN and software configuration. The 8th VIN digit for GV60 RWD models is 'E'. In the Genesis TIS, the motor is referenced by its part number and system designation (EM16). Critical differentiation from the dual-motor AWD GV60: The RWD variant uses only the EM16 rear motor, while AWD models add a second, smaller front motor (EM12). Service parts are specific to the EM16 unit and its associated power electronics module.

Software Calibration

Issue:

Potential for less smooth transition between regenerative and friction braking in cold ambient temperatures.

Evidence:

Genesis SIB G-SB-005-22

Recommendation:

Apply revised control unit software calibration per Genesis SIB G-SB-005-22.

Common Reliability Issues - GENESIS EM-16

The EM16's primary documented service focus is software-related, specifically concerning regenerative braking calibration in cold weather, as addressed by service bulletin G-SB-005-22. Genesis's internal quality data indicates exceptional mechanical reliability for the motor and gearbox assembly. The most critical factor for long-term health is adherence to the high-voltage system and thermal management service schedules outlined in the owner's manual.

Regenerative braking calibration (cold weather)
Symptoms: Noticeably less smooth transition from regenerative braking to friction braking when ambient temperatures are very low.
Cause: Software algorithm in the motor control unit not optimally calibrated for the physical characteristics of the brake system under extreme cold conditions.
Fix: Update the motor control unit software to the latest version as specified in Genesis Service Bulletin G-SB-005-22.
Reduction gearbox whine (rare)
Symptoms: High-pitched whining noise from the rear of the vehicle, proportional to road speed, noticeable during acceleration or deceleration.
Cause: Manufacturing tolerance variation in the gear set or bearing preload within the single-speed reduction gearbox.
Fix: Diagnose using Genesis-specific acoustic tools; if confirmed, replace the entire EM16 motor assembly per OEM procedure, as the gearbox is not serviceable separately.
Coolant leak (power electronics/inverter)
Symptoms: Coolant warning light, reduced motor performance, visible coolant residue near the rear motor/inverter assembly.
Cause: Degradation or failure of seals or hoses in the dedicated liquid cooling loop for the motor's power electronics and inverter.
Fix: Locate and replace the leaking component (hose, seal, or in rare cases, the inverter assembly) using Genesis-approved parts and procedures. Bleed the cooling system correctly.
Connector/wiring harness corrosion (extreme environments)
Symptoms: Intermittent loss of motor power, diagnostic trouble codes (DTCs) related to motor communication or temperature sensors.
Cause: Moisture ingress and subsequent corrosion in high-voltage or signal connectors, particularly in vehicles exposed to coastal or heavily salted road environments.
Fix: Inspect and clean affected connectors; replace damaged wiring harness sections or connectors with OEM parts. Apply dielectric grease to prevent recurrence.
