Hyundai Palisade headlights problems

Filed Oct 24, 2026 · Electrical, Engine · ND

Our 2026 Hyundai Palisade has experienced repeated dangerous electrical failures while driving. XXX All instrument displays went completely black while driving. The engine continued running. Gateway Hyundai in Fargo, ND, checked the vehicle but verbally reported finding no diagnostic codes. XXX While driving on the highway at night, the interior displays and exterior lights repeatedly flickered off and on. XXX The vehicle unexpectedly lost power and shut down at highway speed, requiring a tow to Don Bessette Hyundai in [XXX]. The dealership documented 36 stored diagnostic trouble codes, primarily communication faults. The codes were cleared, and an ECM software update was performed. No confirmed cause was identified. XXX The instrument panel went completely black twice while driving, lasting approximately 10 minutes and 14 minutes. XXX While driving at night, the interior and exterior lights again flickered off and on. Approximately 30 minutes later, the instrument panel went black and the exterior lights dimmed. We pulled over, activated the hazard lights, and restarted the vehicle, but normal lighting did not return. We drove approximately 14 miles with hazard lights on to reach the nearest town. The lights eventually returned, but the instrument panel continued flickering, the front camera repeatedly reported being disabled, and driver-attention warnings appeared during the drive home. These failures continued after dealership service and a software update. We are concerned about another sudden loss of engine power, headlights, or critical driver information at highway speeds. These failures pose a serious safety risk to occupants and other motorists. We request that the federal safety agency investigate these electrical failures.

"The front view camera (FR_CMR) failed due to an internal control chip defect. The component is available for inspection — it is currently at the dealership. Multiple ADAS safety systems were simultaneously disabled, including Forward Collision-Avoidance Assist, Lane Departure Warning, Lane Keep Assist, Driver Attention Warning, and High Beam Assist. This puts both the driver and other road users at risk by removing all active collision prevention and lane keeping systems while driving at highway speeds with no backup warning. The problem has been confirmed by the Hyundai dealership via GDS diagnostic scan showing two DTCs: C160649 (ECU Software Error – Front View Camera) and C180581 (LKAS CAN Signal Error). The vehicle has been inspected by the dealer. Dealer repair order quotes $1,511.87 for camera replacement and calibration. Warning lights for Forward Collision, Driver Attention Warning, and High Beam Assist appeared on the instrument cluster and have remained on continuously. Systems have been disabled since the warning lights first appeared. This is a known internal control chip defect documented in Kia TSB ELE231 (Rev 2, August 2021), covering the identical camera assembly shared across the Hyundai/Kia platform. The same DTCs and same fix — front camera replacement, variant coding, and calibration — are confirmed repaired on other 2020 Palisade Limited vehicles under warranty. Hyundai has not issued a corresponding TSB for the Palisade despite the identical failure mode and shared part. VIN: [XXX] ."

1. The exact component that failed is unknown at this time. The fire appeared to originate in the driver-side front area of the engine compartment near the headlight. Prior to the fire the vehicle experienced engine shaking and a check engine light. The vehicle has been towed to a Hyundai dealership and is available for inspection by insurance investigators, the manufacturer, or safety investigators upon request. 2. The vehicle caught fire while it was being operated on a public roadway shortly after leaving our residence. Flames were visible from the engine compartment within minutes of driving. This created an immediate safety risk to the occupants of the vehicle and to other motorists because the fire occurred suddenly while the vehicle was in motion. 3. The problem has not been reproduced. The vehicle was towed to a Hyundai dealership following the fire incident and is awaiting inspection. The vehicle is a total loss. 4. The vehicle has been inspected by a tow operator and insurance representatives after the fire incident. The vehicle is currently located at a Hyundai dealership and may be inspected by the manufacturer or investigators if requested. 5. Yes. Prior to the fire the check engine warning light illuminated and the engine began shaking while the vehicle was being driven. Within moments of these symptoms a loud popping sound was heard from the front driver-side engine compartment area, followed by visible flames.

I am reporting a recurring, life-threatening electronic failure in my 2023 Hyundai Palisade. On [XXX], while turning into an intersection, the vehicle's brakes spontaneously engaged, stalling the car in the path of oncoming traffic. During this event, multiple critical safety systems failed simultaneously, including the headlights and horn, leaving me unable to warn other drivers. A "violent" surge was required to clear the intersection, risking a high-speed collision. Similar spontaneous recurrences occurred on [XXX] and [XXX], and most recently on [XXX]. These incidents are characterized by "phantom braking," total loss of propulsion, and a complete lack of interior/exterior electronic response. Technical Evidence: Diagnostic scans revealed 16 distinct fault codes (including C161608, C181287, and U012687) involving the Chassis Control Module, Electronic Control Unit (ECU), and communication buses. Despite these logged codes, Hyundai and the dealership have repeatedly returned the vehicle to me, stating they "cannot replicate" the issue, thereby dismissing a documented electronic record of failure. Arbitration Status: I entered into BBB Auto Line Arbitration (Case #[XXX]). Hyundai has contested the claim by attempting to manipulate the "start date" of the defect to February 2024 to avoid Lemon Law statutes, despite dealer records confirming the first occurrence in August 2023. As of January 13, 2026, the dealership is again attempting to force me to take delivery of the unrepaired vehicle. This vehicle is a "phantom" safety hazard. The manufacturer’s inability to replicate a logged electronic fault during a brief test drive does not mitigate the extreme risk of sudden braking and power loss at highway speeds. I am requesting a formal investigation into these specific fault codes and the electronic integrity of this model.

The headlights are fogging up on the inside of headlight with condensation. This problem will lead to two issues. The ability to see at night and I believe the plastic lens will become damaged over time. My friend who has the same type of vehicle including year has the same issue. His vehicle was in a accident. The part for the headlight was $1500. I looked inside the headlight and their are packages of Dri-eaz to absorb the condensation. Since these packages will only absorb for a limited time the issue appears will only get worse and the Manufacture must have know of this issue.

Please reference tracking numbers 11655582 and 11659441. This is an update to those reports. On May 13 I spoke with Deb from Hyundai National Consumer Affairs. Here is what she communicated to me. 1) The headlights are designed this way. 2) She believes it is a standard design used by other companies as well. 3) This closes out my complaint with Hyundai. I have entered [XXX] as the incident date because that is the date I purchased the car. This is a serious safety concern that I believe the federal safety agency should investigate because they continue to make cars with this problem.

This is an update to my previous complaint 11655582. Hyundai replaced the left headlight assembly on 5-5-25. Email I sent to Hyundai this morning: "I drove the car Tuesday evening and noticed the same problem as before the left headlight replacement. Later, at nearly 10:00 PM, I took the car to a dark road with little traffic to get a better look and to take the attached pictures. The outside temperature was 35 degrees with a light drizzle. Here is what I did. 1.I covered the left headlight with the thickness of two towels so only the right headlight shined on the road. I immediately saw the triangular area where there was an absence of light. I walked toward the safety defect to get a good picture. The two dark lines on the left of the picture are the shadows cast by my legs. The leg shadows did not create or impact the safety defect in any way because the safety defect was there when I stood to the side of the car and behind the headlights. 2.I repeated the experiment with the right headlight covered so only the left headlight shined on the road. The result was the same – a dark triangular area where there should be light. 3.When both headlights shine, the two defects blend with one another and project a distracting and unsafe image to the driver. Here are the conclusions that I have drawn from this experiment. 1.There must be a defective component that is used in both the left and right headlights – perhaps a reflector or lens. Perhaps that component is also used in more models than just the Palisade. 2.Since both original headlights and the new replacement left headlight contained this safety defect, the manufacturing dates of the three items might have been weeks or months apart. This makes it unlikely that only my car received three random defects and more likely that this is a widespread problem. 3.The current stock of headlights could be defective and replacing the ones on my Palisade from that stock may not fix the problem."
