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.

APPARENTLY, A FRONT-END COLLISION OCCURRED WHILE THE VEHICLE WAS PARKED AND UNOCCUPIED IN A PARKING LOT RESULTING IN $1232 IN DAMAGE TO BODY PARTS, ANTI-COLLISION RADAR, AND ELECTRONIC CRUISE CONTROL. ASTONISHINGLY, THE BUMPER AND EVEN THE FRONT LICENSE PLATE SUSTAINED ALMOST NO VISIBLE DAMAGE WHATSOEVER. SEE PHOTOS ATTACHED. THE COLLISION MUST HAVE HAPPENED AT EXTREMELY LOW SPEED AND IT IS OBVIOUS THE FRONT BUMPER DID NOTHING TO PROTECT THE REST OF THE CAR--ITS PRIMARY INTENDED FUNCTION. THIS WOULD BE THE EQUIVALENT OF A HOUSE BURNING DOWN TO PROTECT THE FUSE BOX. I CHECKED YOUR WEBSITE AND NOTE THAT THE HYUNDAI IONIQ IS AS YET NOT RATED. I SUSPECT THERE IS A SERIOUS SAFETY ISSUE FOR A CAR …

NHTSA complaint 11362905, quoted in part. Filed by an owner and not verified by NHTSA or by us.

Supplemental to my complaint filed April 18, 2026 regarding Dick's Hillsboro Hyundai (dealer code OR035). The dealership's Service Manager (Robin Farr) provided me with an HMA training report from Hyundai's internal system. Every staff member is listed at "Certified": the baseline tier. No one is above this level. No EV/HEV-specific certification is indicated for any individual. Despite this, the dealership confirmed by phone they could service a 2019 Ioniq PHEV, then performed ICCU/DC-DC converter diagnostics (a hybrid electrical system procedure) and a 12V battery installation in the boot area adjacent to high-voltage components. The vehicle was returned with the hold-down bracket …

NHTSA complaint 11733084, quoted in part. Filed by an owner and not verified by NHTSA or by us.

Following a 12V auxiliary battery replacement at Dick's Hillsboro Hyundai [XXX] , April 3, 2026), the battery hold-down bracket was left completely unsecured. The retaining bolts were absent, (later found loose in the cargo tray area). The battery terminal cover was also improperly secured. I returned to the dealership within twenty minutes of collecting my vehicle and described the condition directly to Service Manager Robin Farr, who assured me it would be corrected. It was not. On April 6, 2026, Withnell Hyundai in Salem, OR (RO# XXX/X) identified the bracket as completely unsecured with me present, documenting: "found the 12V bracket loose on arrival" and "found that battery hold down …

While driving the transmission started driving rough and the car was stuck in ev mode. Wouldnt even go back to hybrid mode. I kept driving until all my battery range was exhausted and lost acceleration and had to pull over the side of the highway. It was late at night so there was no one around or behind me, otherwise I would have been hit. Once stopped the car would not move at all so I called a tow to get me off the highway. I was away from home and had to tow it 120 miles back to the local dealer. The engine clutch actuator failed and ruined my transmission and left me stranded in the middle of the night!

Many times, when I back out of my driveway into the intersection in front of my house the vehicle hesitates for several seconds when shifted from Reverse to Drive. I am in a situation where I cannot accelerate if needed out of the intersection. This is a safety issue in my opinion. The dealer was not able to replicate the problem, even though it happens frequently and has not provided a solution. One time, on a long road trip, while climbing a grade the vehicle could not achieve normal highway speeds (could only get to 20-30 mph). Big rigs were right behind the vehicle and were not happy having to slow down. Again creating a big safety hazard.
