2020 Hyundai Ioniq Electric

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.

When approaching a turn, I let off the accelerator but the car didn’t stop accelerating. Instead, it gently kept accelerating. I applied the brakes and the car started slowing down but not at the same rate I was applying brake pressure. Therefore I floored the brakes to try coming to a complete stop. Sadly, the cars ABS system did not engage, half of the car hopped over the curb at about 20 mph. I was able to steer the car back onto the road where it finally came to a stop but acted like it wanted to keep going until full blackout power loss happened. The car was deemed a total loss by my insurance company American Family. Essentially, the vehicle malfunctioned causing the accelerator to stick which caused the car to be harder to control than designed. The car malfunctioned by not engaging the ABS system as well. There is a recall on this exact problem for the 2017-2019 model but not for my 2020 even though it was manufactured during that campaign. It all happened very quickly and I was very lucky this did not involve another vehicle.

Refill Coolant warning light intermittently signals EV battery coolant problem. Hyundai dealer in Fort Wayne, IN, topped off coolant. Andrew service representative was informed of two YouTube videos explaining recall due to defective coolant ASC1 that crystalizes and/or becomes sludgy. Video reported dealer changed old coolant with an upgraded coolant ASC2 number in a Hyundai Ioniq Limited 2020 Electric Vehicle 38 kw like my vehicle. Fort Wayne, Glenbrook Hyundai dealer has very little experience or training with EV vehicles, since they offered to change the engine oil. https://www.youtube.com/watch?v=CUs-YoGTMlw https://www.youtube.com/watch?v=cCt6MEbaXCI are video links apparently from England due to British accent and Chippenham city mentioned in video. USA NHTSA should add this recall to USA Hyundai Ioniq 2020 38 kv EV's. Defective coolant could cause EV battery failure and potential fire due to overheating and electrical short circuits. The Refill Coolant warning light goes off indicating coolant is sufficient, even when no additional coolant was added.

the Hyundai ioniq 5 doesn't turn on its brake lights when you're using single-pedal driving, as shown in this youtube video: https://youtu.be/U0YW7x9U5TQ?t=97 these should be recalled because you can bring the vehicle to a complete stop without the brakes turning on

The regenerative brake system failed to operate as it normally does, and no indicator lights came on on the dashboard. This unexpected loss of braking force nearly caused me to hit the car in front of me. I had recently disengaged cruise control and was approaching a red light. I pressed my foot on the brake pedal and felt no response from the car. I lifted my foot and pressed again two or three times with no response, neither deceleration nor any change in the regenerative braking meter on the dashboard. I had to press the brake all the way to the floor before the mechanical brakes were activated. This loss of braking power greatly increased my stopping distance and I narrowly avoided hitting the car in front of me. Once the light turned green, I accelerated and tested the brakes again and everything seemed to be working fine, including the regeneration meter. No indicator lights of any kind came on during this incident. This occurred approximately a week ago. I have owned the car for approximately three weeks, and have not experienced any similar issues in the two weeks prior to the incident or in the week since. I have not yet taken it to the dealership as I would not be able to reproduce the issue for them. I will gladly cooperate with any inspection needed to better understand this issue.

This issue is easily repeatable, when braking if you hit a bump (pot hole, etc.) the braking power is greatly reduced & the brake pedal becomes almost impossible to push down to stop the car, making it very hard to stop even when not coming to an abrupt stop.

The traction battery on my Ioniq 2020 went bad after 3 months. The diagnostic panel warned me of an electric issue and the range dropped drastically. The dealer changed the battery no questions asked. My vin wasn't part of the recall. I wonder if the recall should have included a broader range of vehicles.

SHOULD HYUNDAI RECALL THE VEHICLE TO INSTALL THE DEVICES AS ADVERTISED AND SOLD OR REIMBURSE THE BUYERS FOR THE DIFFERENCE AND THE LESSER VALUE CAR SOLD? MY CAR WAS STATIONARY AND NO MALFUNCTION KNOWN YET, BUT LACK OF ASSIST FUNCTION MAKES THE CAR LESS SAFE THAN REPRESENTED WHEN SOLD TO ME.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

Certain IONIQ Electric (AE EV) and Kona Electric (OS EV) vehicles may exhibit a restricted coolant flow condition, which may be accompanied by a warning message (e.g., Coolant Supplement, Refill Inverter Coolant) in the cluster. No related DTCs are stored, and coolant level is normal in the reservoir tank. The coolant flow may be restricted by debris, causing abnormally high Electric Water Pump (EWP) speed. This TSB contains instructions for confirming high RPMs in the EWP, then using the Coolant Flushing Equipment Set to flush and clean debris from the various cooling system circuits. The coolant will be replaced with the updated Electric Vehicle Battery System Coolant (BSC-2) low-conductivity blue coolant.
