On the 2019-2026 Genesis G70, the 3.3-liter twin-turbo V6 in the G70 can develop oil leaks from the turbocharger oil feed lines. The banjo bolt crush washers at the turbo oil inlet degrade over time, allowing oil to seep onto the hot turbo housing and produce a burning smell.
Replace the banjo bolt crush washers with new copper washers at both turbocharger oil feed connections. Inspect the oil feed lines for cracking. Torque banjo bolts to specification to prevent over-tightening.
On the 2019-2026 Genesis G70, the 8-speed automatic transmission in the G70 can exhibit rough or delayed shifts, particularly the 1-2 and 2-3 upshifts during cold operation. The adaptive transmission control module sometimes hunts between gears during light throttle city driving.
Perform a transmission adaptation reset at the dealer. Update the TCM software to the latest calibration. Allow the transmission to fully warm up before spirited driving. A fluid change at 60,000 miles can improve shift quality.
On the 2019-2022 Genesis G70, early G70 models experience infotainment system lag, occasional crashes, and slow boot times. The system can take 15-30 seconds to fully initialize after starting the vehicle, and navigation inputs are sometimes delayed.
Update to the latest head unit software via the Genesis Connected Services app or dealer visit. The 2022+ models received significant hardware and software improvements. A factory reset can resolve persistent lag issues.
On the 2019-2026 Genesis G70, g70 models equipped with the mechanical limited-slip differential can produce a chattering or clunking noise during low-speed tight turns, such as parking lot maneuvers. The LSD clutch packs require specific friction modifier in the gear oil to operate smoothly.
Drain and refill the differential with Hyundai/Genesis-specified gear oil containing the correct friction modifier additive. The differential may need a break-in period after fluid change. This noise is somewhat normal for clutch-type LSDs.
