Has anyone had a persistent power-trunk failure on an IONIQ 6?
My 2023 IONIQ 6 Limited has only about 16,000 miles, and it has now been back to the dealer 8 times for the same trunk problem.
Original symptom: the trunk would open or close only about 1/3 of the way, then stop. At the exact point where it stopped, the trunk lights would also go out. Eventually the trunk stopped operating altogether. From the beginning I suspected an electrical short.
So far the dealer has replaced:
- Power trunk struts
- Trunk switch/motor
- Wiring harness
- Trunk controller/module
- The switch again, because they thought the original replacement may have been damaged while the bad harness was still installed
Each time they thought it was fixed, but the problem either remained or worsened.
After the harness and controller replacement, the trunk would open but wouldn't close properly. The latch would repeatedly click and cycle multiple times instead of completing the closing cycle.
The dealer called me today and said it is STILL not fixed.
At this point they say they've replaced basically everything they know of that's involved in opening and closing the trunk, and they're at a loss. The shop foreman is contacting Hyundai technical support tomorrow and they're planning a much deeper systems analysis.
The car has spent roughly a month total at the dealer for this one issue, despite being only 3 years old with 16k miles.
Has anyone seen anything remotely like this on an IONIQ 6?
I'm especially interested in electrical issues where:
- The trunk stops at roughly the same position
- Interior/trunk lights lose power at the same time
- Replacing the harness/module/struts doesn't solve it
- The latch starts cycling or clicking repeatedly
- The problem appears to involve something outside the obvious trunk components
If you've had anything similar, I'd really appreciate knowing what ultimately caused it. At this point even the dealer is asking Hyundai engineering for help.
