2021 Hyundai Palisade: false forward collision warnings

Filed May 4, 2026 · Brakes, Driver assistance · GA · crash · 5 injuries

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

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.

**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.
