Forward Collision Avoidance 27 Read
Involved in a minor collision. Rear ended another car accelerating from a stop light (low speed). Forward collision warning did not activate. Auto braking did not activate. No airbag deployed
ABS or All wheel Drive did not seem to work while driving on a Highway, and I tried to stop as there was another vehicle on the road which was spinning out of control. If ABS was activated, the car would have stopped, and similarly if All wheel Drive was working, car would not have spun out of control
A collision occurred when the vehicle failed to detect a stationary stop‑sign pole directly in front of it. The forward collision‑avoidance system did not provide any braking assistance or intervention before impact. The vehicle is equipped with the full safety and driver‑assistance package, including camera and…

Car battery completely failed on a busy road
The emergency steering will engage at random times. The car makes a loud noise, a light on the dashboard illuminates, and the car will try to drive into another lane. This happens at least once a week, and it has never happened when there was another car around, so I wasn't about to get into a collision. It has…

While driving in the one pedal driving mode (“iPedal”), it is possible to rapidly slow the vehicle while keeping the accelerator pedal slightly depressed, which is the expected result for this regenerative braking mode. While rapidly decelerating in this mode, however, the brake lights do not illuminate while the…
The Ioniq 5 offers a multi-level regenerative braking system, which slows the car down to varying degrees when letting off the accelerator pedal. While these systems work well to increase efficiency, the behaviour of the brake lights while in use is concerning. Very often the car is slowing considerably, enough to be…
When my car is configured to one pedal driving mode (iPedal), the brake lights only illuminate when the accelerator pedal is fully released. This means the car may decelerate rapidly (up to 0.25G or 2.5m/s^2 according to a report) under regenerative braking, while the brake lights remain off. I believe this is a…
Ioniq 5 years to avoid — and the clean ones
Complaints per model year. More reports usually means more cars on the road as well as more trouble, so read the crash and fire columns alongside the count.
| Model year | Complaints | Top system | Crashes | Fires |
|---|---|---|---|---|
| 2025 | Air Bags | 3 | — | |
| 2024 | Air Bags, Seat Belts | 5 | — | |
| 2023 | Air Bags | 12 | 2 | |
| 2022 | Air Bags | 7 | 1 |
The same model year, different builds
Every complaint carries the first 11 characters of the VIN — plant, year, body and engine. That is a production series, and complaints are spread across them very unevenly.
| Measure | Value |
|---|---|
| Distinct production series | 237 |
| Average complaints per series | 5.5 |
| Worst single series | 23 complaints |
| Average age at failure | 1.5 years |
A model average of 5.5 hides a worst series at 23. Enter a VIN above to see the numbers for that exact build instead of the model as a whole.

How we count
Every figure here comes from complaints owners filed with NHTSA — 1,115,966 of them, covering 2,019 models built between 1981 and 2026.
A complaint is an unverified report: someone wrote down what happened to their car. It is not a confirmed defect and not a recall. What makes the volume useful is the pattern — when thousands of owners of the same build describe the same failure, that is a signal no marketing brochure will give you.
Two things we do that the source does not. First, we compute the age of the car at the moment of failure from the incident date and the model year. Second, we group complaints by the first 11 characters of the VIN — the production series — so a bad plant run does not disappear into a model-wide average.
