Hyundai / Kia ECU Repair FAQ
What causes Hyundai and Kia ECUs to fail?
Common causes include voltage spikes from jump-starting, capacitor aging on higher-mileage modules, water intrusion through firewall grommets, and connector corrosion. Hyundai/Kia ECUs are repairable in the vast majority of cases — we identify the failed component and replace it rather than swapping the entire unit.
Can you fix Hyundai / Kia DCT (dual-clutch transmission) problems?
We repair the TCM that controls DCT behavior. If your Hyundai or Kia is shuddering, jerking at low speeds, or throwing P0700-series codes related to the TCM (not the clutch pack itself), we can repair it. Contact us with your fault codes to confirm the TCM is the root cause.
Do you program the immobilizer after ECU repair?
Yes. We re-register your transponder keys to the repaired ECU as part of our programming process. Your existing keys will work after reinstallation on most Hyundai and Kia platforms.
Do you repair Genesis ECUs?
Yes. Genesis vehicles share the Hyundai platform, so our full ECU, TCM, and immobilizer repair capability applies to all Genesis models.
How long does Hyundai / Kia ECU repair take?
Most repairs complete in 48–72 business hours from receipt. Rush 24-hour service is available for an additional $75–$100.
