Blind spot warning system stopped working. Then speedometer stopping working registering 0 both digital and the circle. Then all lights started going off on the dashboard. My dealer cleared codes and errors went to history but not active. When I went to drive again blind spot didn’t work and speedometer didn’t work. I didn’t drive further after that. I heard there was an issue with the 2022 dashboard cluster.

Component/system, available for inspection? Rear visibility system — AVN head unit's processing of the rear camera image. On shift to reverse, screen flickers, shows blinking green, or no rear image. Vehicle available for inspection. Original camera was replaced Jan 2026 and retained by the dealer, not returned. Safety risk? Daily driver used for school pickup. Failure is warm-restart dependent — engine running, repeated shifts into reverse — which is exactly the pickup-line condition. Rear visibility is lost while children move behind the vehicle. System works reliably only after 25+ minutes shut off. Reproduced/confirmed by a dealer? Yes. Crain Hyundai of Bentonville, RO H3CS1330630, 1/13/26. Camera replaced; failure persisted. Same RO then states the head unit "IS GETTING TOO HOT" and needs replacement. No further diagnosis performed. Inspected by manufacturer, police, insurance? Not directly. Hyundai Motor America reviewed (Cases 42288449 / 42326908 / 42619220) but relied solely on dealer diagnosis and confirmed in writing 6/22/26 that it does not audit dealer measurements. No police or insurance involvement. Warning lamps/symptoms, first appearance? First reported by my wife (primary driver) in June 2025; not reproducible on demand for some time, consistent with the intermittent warm-restart pattern later documented. No warning lamps, no DTCs in any accessible module. Only symptom is the display failure itself. 60+ structured tests logged 2/2–2/9/26 documenting the warm-restart pattern. Mileage 63,679 at service. Unresolved as of 8/3/26.

On XXX, after leaving an appointment at an office building, I returned to my vehicle and noticed that the driver’s seat recline function was not working properly. The seat was already pushed forward to its highest position and would not recline further. I was still able to enter and operate the vehicle somewhat but remained parked. I reviewed Hyundai resources to see whether there was an update or known issue related to the seat concern. When I could not resolve the issue through available resources, I contacted the Hyundai dealership in Henderson. I provided my information and explained that the driver’s seat recline function was not working. I was transferred to Hyundai Customer Service. During that call, I explained that I was approximately 15 minutes away from the dealership and requested repair of the issue regardless of warranty status because I considered it a safety concern. This never happened before at all. While I was speaking with the Hyundai Customer Service representative, the driver’s seat moved again unexpectedly. As a result, I moved forward toward the steering wheel area. After that movement, the vehicle rolled or moved forward and contacted the rear of another vehicle. After the collision, the driver’s seat recline function still was not operating properly. I documented the condition with video evidence, and two witnesses observed the vehicle and the seat condition after the collision. When I contacted Hyundai, I was very upset to learn that the call I had with the customer service representative was not documented anywhere. Also, no one contacted me although I was in distress, crying, and in the accident and the customer service representative knew this. There was no aid or phone call follow ups to me by Hyundai customer care at all. Hyundai Motor America opened a case investigation and instructed me not to perform repairs at this time so the vehicle could be preserved for inspection.

On April 22nd my camera worked on my car but did not prompt warnings - I was in a parking lot and was backing up and tapped the car behind me. It is then that I noticed no beeping on getting close to the car. No damage to either car fortunately as they stated I was going ever so slow. On April 23rd got it in to the Hyndai dealership service department and there was another vehicle in there for the same issue I was told by them. WELL..... was told there is no recall. They replaced a harness I was told and final bill was $1126.30. NOt under warranty because my car has 113,000 miles. I would be glad to provide the final billing. I am reporting as there seems to ba an issue with this and I would hope that it gets addressed and if so would like my bill of $1126.30 reimbursed.

While driving the vehicle ahead brake suddenly. When I applied the brake pedal, it felt abnormally stiff/stuck and did not provide Norma breaking response. Th vehicle did not decelerate as expected despite immediate pedal input. At the same time, the Forward Collision Avoidance Assist system did not activate or provide any braking assistance. Due to the lack of effective braking, I was unable to stop in time and a collision occurred. The primary concern is a potential failure or malfunction in the braking system occurring prior to impact combined with the apparent failure of the automatic emergency braking system to engage. This created a situation where the vehicle could not be stopped under emergency conditions posing a serious safety risk

Whilst driving on the highway, the passenger rear quarter glass detached from the car and flew into the bushes on the side of the road. I heard a whistling sound coming from the inside of the car. I checked to see if one of the windows had been opened, yet they were all closed. I figured I would check the car when I got home to see where the disturbance was coming from. Yet while I was in the right lane, traveling at the speed limit of 70 mph, the passenger RR Quarter Glass Panel detached from the side of the car. The panel was lost in the bushes but most likely shattered on impact. This may be the result of a bad urethane bead when securing the panel during assembly.

While vacationing in Myrtle Beach with my family the vehicle alarmed and then progressed to critical failure of safety functions while traveling at approximately 55mph on Friday April 3, 2026. The vehicle was brought to Myrtle Beach Hyundai where it was eventually diagnosed and repaired as an Alternator issue that I have found to be common with this specific vehicle. The issues I have experienced with this vehicle go far beyond a typical mechanical concern. Over time, the vehicle has exhibited repeated electrical system malfunctions, including: - False blind spot collision warnings when no vehicles are present - Intermittent failure of the crash avoidance system - Loss of cruise control functionality tied to system faults - A broader electrical failure event that triggered multiple warning systems simultaneously Most concerning, these failures have occurred while the vehicle was in motion, creating an unpredictable and potentially hazardous driving condition. The loss and unreliability of critical driver-assist and safety systems directly impacts driver awareness and vehicle control, which raises serious safety concerns. Despite multiple attempts to have this diagnosed through the dealership network while under warranty, no definitive root cause was identified, and the issue has persisted. This suggests the possibility of a systemic electrical defect rather than an isolated component failure. Additionally, I have found that similar complaints involving electrical system irregularities and cascading warning system failures have been reported by other owners of this model, further supporting the concern that this may represent a known or emerging defect pattern. Given these factors, I do not believe this situation should be categorized as routine. Instead, it warrants review under the lens of: - Vehicle safety risk - Potential defect trend - Failure of critical driver-assistance systems during operation This vehicle has not been inspected by the manufacturer.

Front passenger side and second row passenger side seatbelt are hard to latch and randomly unlatch.. I took it in for service several times during the warranty to ask them to look at it, and they could never replicate it.

**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.

The forward collision warming sign just activated when there is no danger. The car will suddenly apply sharp brakes when you are even on the high with a speed over 65 miles per hour. It is very dangerous and scary and can lead to accidents. My car false alarms get activated more than three times a day. I hope Hyundai will recall this and fix this issue.
