Vehicle Weaknesses

WeaknessCost
✖ICCU Failure (Integrated Charging Control Unit)

SiC MOSFET degradation through thermal cycling blows internal 130A fuse. 2–10% failure rate per Consumer Reports — industry average is below 1%. Same E-GMP unit as Ioniq 5/6/EV6. Revised part issued January 2026.

Symptoms: Audible pop from rear, 'Check EV System', charging impossible at all stations, 12V goes dead
from 30,000 km
Ad 36400-1XFA0 ICCU Hyundai E-GMP
 High
✖HV Battery Cell Failure (P1AA700)

BMS detects >180 mV inter-cell voltage differential, charging stops at 55–62%, DC fast charging impossible. Requires full pack replacement. Lemon Law repurchases documented.

Symptoms: Charge limit at 55–62%, 'Check EV System', DC charging refused
Ad HV battery E-GMP 84 kWh
 High
!12V Auxiliary Battery Drain

Bluelink app polled up to 5,000 requests/day, draining 12V in 2–3 days. A subtly failing LDC in the ICCU can also leave the 12V undercharged. Software update limits to 20 transactions/day.

Symptoms: Vehicle won't start, various system warnings, Bluelink error messages
Ad 12V AGM battery Ioniq
 Low
!AC Charge Port Overheating at Level 2

48A Level 2 charging causes onboard charger/port to reach 99°C+ after 30–38 minutes, session drops or stops. Affects all E-GMP models. Class action lawsuit filed.

Symptoms: Charge rate drops abruptly, charging session stops, overheating warning
Ad charge port E-GMP Hyundai
!Thermal Throttling on Track

After ~15 miles at full throttle, battery throttles power. The 6 N improves on the 5 N with three preconditioning modes (Drag/Sprint/Endurance) and enlarged chiller, but physics remain: 77 kWh/100 km under track load. 18 minutes charging + cooling to recover.

Symptoms: Noticeable power loss, system warnings, reduced acceleration

Which engine is recommended? +
Be careful: Ioniq6N-DM (Dual Motor AWD). No engine is rated 'Good Choice'. The most fun to drive is the Ioniq6N-DM (Dual Motor AWD).
Which Hyundai Ioniq 6 N CE N engine is the most fun? +
The {code} ({displacement}) offers the most driving fun in the Hyundai Ioniq 6 N CE N — rated: "Legendary!". {description} 478 kW, simulated 8-speed paddle shifts, 3-parameter drift optimizer. 50 kg lighter than the 5 N with better aero (0.27 Cd) and a stretched wheelbase — more composed at high speed, slightly less tail-happy, still completely unhinged when you want it to be. Three battery preconditioning modes (Drag/Sprint/Endurance) push thermal throttling further out. 18-minute 10–80% charge means track sessions stay short and sweet. The 5 N surfs the crowd, the 6 N chases the lap time. But layering fake sounds onto an electric motor is a dead end. The real path: physically simulate an entire combustion engine — gas flows, pressure waves, their influence on sound. The torque curve maps onto the EV drivetrain, the dynamic sound character — an engine that sounds different depending on load, RPM and throttle position — hits your ears. That's exactly what https://engine-sim.parts is trying to do — take a look at this project and whatever you do, don't miss this demo: https://youtu.be/sUdnJTC2w9I?si=2sEIqQXSnDWOaVRV&t=1443 — what this project delivers at this early stage is absolutely mind-blowing.
