Hyundai Palisade collision warning problems

Filed Nov 5, 2026 · Electrical · WA

Vehicle auto detects when a trailer is connected to the car. The auto detect erroneously reported a trailer is connected, and activates Tow Mode. Tow mode deactivates or restricts, Blind-Spot Collision-Avoidance Assist, Safe Exit Assist, Collision Avoidance for Blindspot, Lane Keeping Assistance and Lane Following Assistance. Dealer says this was caused by a defective Tow Hitch Wiring Harness.

On August 10, 2026, at approximately 12,302 miles, I took the vehicle to an authorized Hyundai dealer after it stalled multiple times, including once while accelerating. I also reported sluggishness/loss of power. The dealer was unable to duplicate the problem. The vehicle subsequently stalled two additional times. In September 2026, while driving at highway speed with cruise control engaged, the vehicle suddenly and aggressively decelerated/braked as though it detected an obstacle ahead, although no vehicle or obstacle was present. A similar event occurred the following day. Unexpected braking, loss of power, or stalling at highway speed creates a serious collision risk. I have also experienced a forward-collision warning when no vehicle was in front of me and intermittent jerking/hesitation. I returned the vehicle to the Hyundai dealer on September 22, 2026, at approximately 14,548 miles. The dealer performed diagnostic scans and approximately 42 miles of road testing. No relevant DTCs were found, the problems could not be reproduced, and no repair was performed. The dealer documented the result as No Trouble Found. There were no consistent warning lamps or messages before the stalling or unexpected deceleration. The cause remains unresolved despite multiple dealer visits.

The vehicle brakes malfunctioned while driving over bumpy pavement in a parking lot. There was a loss of ability to stop the vehicle, the breaks seemed locked or ineffective. This cause me to come close to rear ending the vehicle in front of me. My foot was pushed FIRMLY on the break and the vehicle seemed to continue to lurch forward. The collision warning alarm was sounding and the brake pedal was vibrating.

We were traveling on XXX near XXX at 60 MPH (Speed Limit 70 MPH but it was raining). The vehicle in front of us abruptly stopped due to a rear crash causing the chain of vehicles behind to brake suddenly. I had to hard brake - the emergency collision warning turned on but at the same time - the 2nd row driver side passenger's seat belt automatically released putting the occupant in danger.

On 2 separate occasions, under similar circumstances, the collision warning systems, both front and rear, applied the brakes for no reason. When reversing slowly (foot slowly off brake pedal) from a parking space on an almost empty rooftop parking lot; I confirmed there was no foot traffic or moving vehicles before I started to back up. The brakes automatically applied (no screen display); I reapplied the brake and was then able to reverse normally. On a normal service visit to my dealership, I mentioned the incident and it was noted on my invoice. About 3 weeks later, at a full stop at a stop sign, I was about to turn left onto another road. After confirming there was no cross traffic of any kind, and before I had completely released the brake, the collision assist engaged and suddenly applied the brakes (again with no screen display but an audible thump). Again, I was able to reapply the brake and then accelerate to make the turn. Since the same event had happened twice, I went directly to my local Hyundai Service Center and reported it. They kept the vehicle for a week and tested it thoroughly. Nothing showed as being faulty. When I picked up my vehicle on 5/22/26, they informed me that there's a known issue (the federal safety agency Campaign # 26V316) with other Hyundai models (not the Palisade) and that an update for the forward collision avoidance system in those models will be coming mid-summer. As the Palisade is not included in the Campaign list of makes/models, but has the exact same event/problem, I wanted to report this for inclusion in the safety recall. I was not injured in either event but anyone with this issue could potentially be at risk in the future.

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.

While starting to drive from a red light, I was about a car length or 1.5 car length away from the vehicle ahead of me. As I was driving forward because the light turned green keeping the same distance, the car gave me a second and a half of the collision warning, then immediately went to emergency break-in and stopped me in the middle of the intersection during morning rush hour. The car behind me almost slammed into me. This happens once in a while when backing up in parking lots. There’s no one behind me but a curb or some grass. I’m not close it to but the emergency breaking system comes on and stops me. Since the stop is abruptly there’s been times another car could have potentially hit me while either trying to go around me as I’m backing out of a spot in a parking lot or as I mentioned today the car stopping me in the middle of the intersection during a green light. It’s been so random, it hasn’t been reproduced. The car was inspected for the other recalls a few days ago but not for the emergency braking system. The warning was very quick today. It didn’t last more than a second before it started to brake itself. I didn’t have time to react to the warning. After researching online I see this is more common than I thought.
