Expert Hyundai Nexo transmission service in Chicago. Free computer diagnostic, lifetime warranty on rebuilds, all years.
2019–present: Single-speed fixed-ratio reduction gear driven by fuel cell electric powertrain; front-wheel drive No multi-speed transmission — single gear ratio from 0 to top speed Electric motor output: 161 hp; peak torque: 291 lb-ft from 0 rpm
Nexo drivetrain service requires EV-certified technicians and high-voltage safety procedures. Reduction gear fluid inspection and replacement is the primary scheduled service item. Seal leaks are repaired at the output shaft without full drivetrain removal in most cases. Bearing noise requires reduction gear disassembly — diagnosis includes listening test under load and fluid metal particle analysis. Regenerative braking judder is often software-related and addressed by reflash. We are equipped for full fuel cell vehicle drivetrain service including high-voltage isolation procedures.
Dedicated EV reduction gear fluid (Hyundai-specified); approximately 1.5–2 quarts; replacement interval approximately 60,000 miles or as needed based on condition
Fluid service: same day; seal replacement: 1 day; bearing replacement: 2–3 days; full reduction gear rebuild: 3–4 days

Not in the traditional sense. The Nexo uses a single-speed fixed-ratio reduction gear — there are no shift points or clutches. The electric motor provides full torque from zero RPM, eliminating the need for multiple gear ratios.
No — the Nexo's fuel cell electric drivetrain requires high-voltage certified technicians and specialized equipment. We are EV-certified and equipped to safely service the Nexo's drivetrain and electrical systems.
Fluid inspection every 30,000 miles; fluid replacement every 60,000 miles or if contamination is found. Seal and bearing inspection should accompany each fluid service.
Yes — Hyundai covers the fuel cell system and electric drivetrain components under a 10-year/100,000-mile warranty in California and a 5-year/60,000-mile warranty in other states. Confirm your specific coverage with your selling dealer.
Usually a calibration issue in the regenerative braking blend — the transition between regen and friction braking can produce judder if software parameters are off. Hyundai has issued updates addressing this. If judder persists after reprogramming, brake system inspection is next.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
