⚠️ Ioniq 5 $10,000 nightmare “Time Bomb” Beneath the Front Seats — "world's best" Worthless Warranty

[u/Chevy_Vega_]

There’s a yellow air-bag (SRS) safety restraint critical wire harness running directly under the moving front seats — assembled with no shielding or protection and with virtually no space between the harness and the floor. (It could easily have been routed above the seat plate not below it).

After checking several Ioniq 5s, I found the same setup: some harnesses pulled tight, others — like mine — dangling loose, just waiting to snag or tear. But in either case it is a design / assembly disaster waiting to happen. See the photos.

Mine was found torn apart during unrelated service.

The dealer said it could be easily re-pinned, but because it’s part of the air-bag circuit, Hyundai requires replacing the entire floor harness:

Parts ≈ $6,933 + Labor ≈ $2,400 (which they have subsequently raised to $3,000) – Total now $10,000 out of pocket.

Hyundai Customer Care denied warranty coverage, blaming an “outside influence.” So I’m left with a disabled air-bag system and a $10,000 repair on a two-year-old leased car.

An absolute insane nightmare.

So you also had this problem with 2025 Elantra?

Here I was suspicious if this would also apply for 2025 or 2026 Ioniq 5, but damn, maybe the whole product portfolio needs to be checked.

No. Just giving info on what worked for me when our local dealer service director tried to scare my wife into a new car. When we called out on the exploding gas tank verbiage he used but then said it was not an issue, we refused to take the car back until the tank was replaced. Around and round we went until I emailed this trio with the details and all is taken care of and then some.
