Automatic Emergency Braking problems of the 2021 Hyundai Palisade

**vehicle:** 2021 Hyundai Palisade calligraphy, ~75,000 miles. Purchased February 2025. **problem 1 - forward camera failure:** the forward-facing camera system controlling lane keeping assist, emergency braking, and lane departure warning has completely failed. Dashboard warnings appeared in recent weeks including "check forward safety system" and "forward safety system disabled" before total failure. This eliminates critical safety features designed to prevent accidents, significantly increasing collision risk. Camera unit behind rearview mirror available for inspection. **problem 2 - rear shock failure:** rear shock absorbers have failed, causing excessive clunking and compromised vehicle stability. Rear suspension has been clunking since purchase in February. This creates dangerous driving conditions with reduced stability, increased stopping distances, and poor emergency handling. This is a known issue covered under Hyundai technical service bulletin 22-22-001h. **safety risk:** both failures create serious safety hazards - eliminating collision avoidance systems and compromised vehicle control/stability. **professional confirmation:** local Hyundai dealer has confirmed both the camera system failure and rear shock absorber failure through diagnostic testing and inspection. **components available:** both the failed camera system and rear shock absorbers remain available for inspection upon request. **request:** investigation and remedial action for these safety-critical defects, particularly given the rear shock issue is a documented manufacturing problem per TSB 22-22-001h.

On expressway traveling through atlanta, changing lanes with plenty of clearence using signal at approximately 55 mph when suddenly alarm sounded and breaking system engaged bringing car to almost complete stop. Could not accelerate and fortunately made it to berm area without causing serious accident. Turned engine off and restarted vehicle and continued on my way. Had vehicle checked at dealership and they said “all checked out and we found no diagnostics problem”. Also weren’t able to duplicate incident. I hope to god I am unable to duplicate the incident and cause fatalities including myself.

While driving on the interstate on a clear sunny day at approximately 70 mph within the span of five minutes my vehicle’s emergency braking system engaged (with visible warning on dash screen) causing breaking with a steering deviation forced to the right. There was no one immediately in the lanes next to me, and the car in front of me was 4-5 car lengths ahead, at least.

Environment: passing a single car on a two lane deserted highway. Daytime, sunny, no rain. Issue: the vehicle's emergency braking system activated (brakes were automatically activated along with the emergency braking cue in the instrument cluster) when the vehicle was returning into the right lane, almost causing a collision between the two vehicles at 85 mph. This occurred a second time 15 minutes later under the same conditions. The car was taken to the dealership for inspection and repair. The dealership test drove the vehicle and could not replicate the issue. Hyundai engineering noted that since they were not able to replicate the issue and there were no active codes there is nothing wrong with the vehicle. If the radar is functioning properly, there must be an issue with the software of the vehicle.

The contact's friend owns a 2021 Hyundai Palisade. The contact stated that while driving 70 mph, the emergency automatic braking inadvertently engaged. The emergency braking system warning light was illuminated. The driver had to manually release the parking brake. Additionally, while driving a stone struck the front windshield causing a crack. The vehicle was taken to the local dealer and the contact was informed that the vehicle was working as designed. The contact was also informed that the windshield was on backorder. The vehicle was not repaired. The manufacture was notified of the failure however, no further assistance was provided. The approximate failure mileage was 10,000.
