Hyundai Kona Elektro
High-output permanent-magnet motor on the E-GMP platform. 800V ultra-fast charging and outstanding efficiency.
Modern crossover, plays it safe
The new Kona SX2 is well-built and modern, but base spec stays firmly in sensible daily-driver territory.
Engine Weaknesses 7
The Integrated Charging Control Unit (ICCU) can be damaged by electrical overload and no longer charge the 12V battery. The vehicle progressively loses all electrical functions while driving.
Symptoms: Dashboard warnings and beeping, progressive power loss, vehicle enters emergency mode, 12V battery not charging.
The ICCU (Integrated Charging Control Unit) of the E-GMP platform is a systemic weak point: defective transistors/MOSFETs or software faults cause the 12V battery to no longer be charged. Typical failure pattern: vehicle loses power progressively while driving.
Symptoms: Warning 'Limited power', fault code P1A9096, 12V battery flat, vehicle no longer driveable
Defective heat treatment by a supplier led to driveshafts on the Ioniq 5 and 6 (production 2021–2023) that could break. Recall 41D022 affected 155,760 vehicles worldwide, including 46,604 in Germany.
Symptoms: Sudden loss of drive, noises from drivetrain, vehicle coasts to a stop
Third-party Bluelink apps can trigger up to 5,000 server requests per day, constantly waking the vehicle. The 12V battery drains within hours. Hyundai has limited server traffic to 20 requests per day.
Symptoms: Vehicle completely dead after a short standstill, no remote unlocking, no start, jump-start required.
Ioniq 5 and Ioniq 6 occasionally show new malfunctions in recuperation strategy, regenerative braking or charging control after software updates. OTA updates can also introduce new bugs.
Symptoms: Changed recuperation behaviour after update, unexpected driver assistance interventions, occasional system reboots.
The Ioniq 5's charging flap can cause elevated quiescent current (approx. 4 A) in cold weather, draining the 12V battery within 24 hours. Replacing the charging flap resolves the issue.
Symptoms: Vehicle dead after one night of standing, especially at temperatures below 10°C, problem recurs.
The Ioniq 5/6 also suffers from the unexpected 12V drain problem known from the first Ioniq. Control units do not reliably enter standby mode and drain the auxiliary battery.
Symptoms: Vehicle won't start in the morning, system reset required, all warning lights on
Vehicle Weaknesses 8
A software fault in the dual-clutch gearbox transmission control unit can trigger unexpected strong vehicle deceleration. KBA recall affects approx. 10,575 vehicles worldwide, recall code 41D037.
A short circuit in the battery wiring in the fuse box can cause a fire. Recall code 41D009 affects approx. 4,471 vehicles in Germany (combustion engine models). Dealer installs cable protection.
The mild hybrid variant (48V) shows reduced throttle response after extended motorway driving. No fault codes stored. Cause unclear, possibly thermal throttling of the electric motor.
The 8-speed automatic gearbox on the Kona SX2 shows irregular shifting, judder at low revs and metal debris in gearbox oil. Parts lead times at dealers are long as replacements are hard to source.
BlueLink connectivity service requires regular resets; infotainment shows glitches during navigation updates. Usually fixable by software updates at the dealer.
The exhaust system on the Kona SX2 shows above-average corrosion from just 3–5 years. Defect rate above class average according to data, especially on short-distance vehicles.
BlueLink connectivity problems and infotainment crashes are known weak points on early-production Kona SX2. Software update at dealer usually resolves symptoms permanently.
Early 2023 model year examples show crashes and sluggish response times in the 12.3-inch infotainment system as well as connection dropouts with wireless smartphone mirroring. Software updates from 2024 noticeably improve the situation.
