NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

The Hyundai Ioniq was designed with a dual clutch system for the electric motor and gas motor. This was done to disengage and engage either separately when necessary for low power, regen braking, etc. However, this design heavily impacts the behavior of the brakes and safety of the vehicle overall. When the brakes are applied, the ECU will turn off the gas engine to conserve gas in regen braking mode. Additionally, the ECU will downshift the transmission. Downshifting the transmission and disengaging the gas engine become an issue because conducting both actions removes significant resistance in braking. Causing the vehicle to lurch when the downshift occurs while also increasing stopping …

crash

On June 10, 2021, when driving from Topeka, KS to Park Ridge, IL, there was a failure in both the Adaptive Cruse Control System as well as the Lane Keeping Assistance System. The ACC system started the car moving forward from a complete stop without my intent and the LKA turned the car to the right striking a semi trailer that was completely stopped. Additionally there was no warning from the Forward Collision Warning system

While attempting a slow right turn from a complete stop at an intersection, I heard a loud thunk sound followed by an immediate loss of power steering response. The steering wheel spun freely with little resistance while the front tires did not respond proportionally. I was able to safely pull over. Upon restarting the vehicle it produced an abnormal wheezing sound suggesting additional mechanical stress. At the time of the failure the vehicle had approximately 40,000 miles, which I believe represents a premature failure for a safety-critical steering component. The vehicle was brought to a Hyundai dealership for inspection. The dealer pulled diagnostic fault codes, found none, performed a …

The charge controller failed twice and one of the times I was out on a dangerous road where there wasn’t a safe spot to pull over. It was very sketchy.

The horn on my 2020 Hyundai Ioniq has stopped working. I checked the fuses and they are all good. Hyundai currently has several other models with recalls or at least known to fail. Yes my vehicle is available for inspection and no I have not had it looked at yet… dealer wants to keep it for 3-5 days to diagnose and further, given the nature of the issue, I don’t feel I should be responsible for any fees involved in doing so. It poses me a major safety concern as I cannot warn other cars of potential collision etc. Unfortunately, this problem does not have any type of warning message to let you know. I had to find out by trying to use my horn when someone almost hit me. This appears to me as …

Car has two horns, both STOPPED working completely about 2 1/2 years ago and were replaced by the Hyundai dealer in Florence, SC. High pitch horn failed again about 1 year ago, and low pitch horn has now failed. Local Hyundai dealership in Pensacola, FL npow wants $800 to replace what should be fully covered. Car now has 75,00 miles so they say it us out of warrenty. But, a safety issue on a known problem (per Hydai frum on line and personal experience) should be fully covered by Hyundai.
