One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 1,065 complaints with NHTSA since 2015. 403 of them name Service Brakes — the same broad component group this bulletin is filed under.

On September 21, 2022 I had sat in my car for about 8 minutes idling with the key FOB in the car with me. I have as not on remote start. When I left the parking lot and drove a half a mile my engine shut off and a loud beep and red triangle warning came on that read engine failure and to start engine.
2023 Hyundai Palisade · Engine · filed with NHTSA Oct 7, 2022 · ODI 11488319
When driving at a low rate of speed to stop, when you hit a bump or uneven road, the brakes lock up, the vehicle will lurch, and will not stop. This has happened several times on pavement, gravel roads, and dirt roads. I have had to steer off the road to keep from going into oncoming traffic.
2025 Hyundai Palisade · Service Brakes · filed with NHTSA Jun 18, 2025 · ODI 11667613
Two times my car has lost its ability to break, and when I try to break it feels like the break pedal was very hard to push down. The car was very lurchy but finally came to a stop when the breaks finally engaged. The feeling is like when you press on the breaks when you are sliding on ice.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.
