Vehicle purchased new in August 2026. Within 80 miles, it began experiencing a recurring electrical fault causing simultaneous warnings across the steering, braking, and driver-assistance systems (DTCs C28C586, C164286, C181486, C181483, logged via Hyundai's Bluelink diagnostic system). The fault has recurred at least 9 times between 80 and 1,121 miles despite three repair attempts (8/28/26, 9/8/26, 9/14/26), including one escalation to Hyundai's national TechLine (Case #2026091700002) referencing TSB 25-GI-016H. Each repair was declared successful, and the identical fault returned within days each time. During active occurrences, dashboard alerts have included "Check Driver Assistance System," "Check Rear Cross-Traffic Safety System," and simultaneous warnings for lane departure, forward collision, blind spot, and anti-lock braking systems. This represents a loss of reliable communication between safety-critical systems (steering assist, ABS, and driver-assistance) while driving, creating a risk of degraded steering or braking response without warning. Manufacturer has declined to repurchase or replace the vehicle.

My "Vehicle Health" reports all systems good on the BlueLink App-- however, when I open "diagnostics history", it shows 8 repeated reports under DTC: C183987 (SAFETY - Anti-lock Braking System). There is also a reports for a DTC C186B87 (ELECTRICAL- Lane Departure Warning System), and a C188087 (null). So there are 10 total reports of this in my history between 11/7/2025 to 9/18/2026. The reports for the anti-lock breaks were reviewed by the dealership and advised by Hyundais tech line that they were just glitches in computer system. However, they have continued. And on top of that, I just filed a separate report about my car accelerating when I pressed the brake (thankfully it happened in a parking lot)-- no idea if its related but its all fishy. Thus I will be going back for another review by dealership "service" team. Initially the first few reports did have an ABS light that showed up on my screen which is what prompted me to look into the app for issue only to see it said everything was fine, until I looked deeper at the historical reports. But lately there has been no ABS light showing up on my dash but the reports are still coming in.

When using "Lane Keeping Assistance" the vehicle pulls slightly to the right and continues correcting itself creating a snake like pattern. This is unsettling and other vehicles that I own do not have this pattern including the same model from previous years. This feature is design for safety, however when "Lane Keeping Assistance" in operation the pulling to the right looks like you are going into the other lane then correct's itself and repeats not giving the feel of safety. I have taken it do the dealer and file a report to hyundai both parties had stated they cannot do anything without an error code. I have seen other customers complain about this issue with my make/model. Please help correct this issue. Thank you

I am reporting multiple recurring safety concerns with my 2026 Hyundai Palisade. Loss of acceleration: Under heavy throttle, the engine revs to approximately 5,000 RPM but the vehicle does not accelerate as expected. This has occurred repeatedly and appears more likely after the vehicle reaches normal operating temperature. During one incident on the highway, I needed to accelerate quickly to avoid surrounding traffic, but the vehicle did not respond as expected, creating a potential safety risk. An authorized Hyundai dealership inspected the vehicle and reset the transmission adaptive values, but the condition remains. Lane Keeping Assistance: The Lane Keeping Assistance system consistently positions the vehicle toward the left side of the lane instead of properly centering it. The issue has been reported to the dealer, but the condition remains unresolved. Power second-row seat: The power second-row captain’s chair can continue moving while folding, creating a hand-crush hazard if a person’s hand is in the path of the seat. It also interferes with proper third-row seat operation. This issue has been reported to the dealer and remains unresolved. These issues have been reported to Hyundai and remain unresolved after dealer inspections. The vehicle is available for inspection, and I have documentation and video evidence of the acceleration concern.

The speedometer, lane departure, heat gauge, and RPM’s and the whole speedometer cluster will stop working. It does this all the time you never know if it will work and then sometimes it will randomly come back but it’s more in the heat it will not work.

"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] ."

. What component or system failed or malfunctioned, and is it available for inspection upon request? ---------- Nothing failed but the lane assist feature forces the car to drive hugging the left lane and not on the center of the road. This can be very dangerous on a freeway when passing big wide trucks. If you use the cruise control this feature automatically turns itself on. . How was your safety or the safety of others put at risk? ------ When the lane assist is turned on the car drives close to the left line and not on the center of the road and this could be very dangerous when passing large wide vehicles or those with wide trailers. Has the problem been reproduced or confirmed by a dealer or independent service center? ------------ Yes. I took it to the dealer and they said that's how the car was designed and there is nothing they can do. They asked me to contact the Hyundai Customer Affairs. I opened a case number with Hyundai Customer Affairs. They said that if the dealer did not find a problem then there is nothing they can do. I am stuck with the problem. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ------------------- See above. When I googled to see if other people are complaining about the issue, I found out that there are other people complaining but no formal complaint has been put forward. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? ------------ The issue has existed from the dealer. There are no warnings or anything

When using lane assist the vehicle is pulled into other lanes, including into oncoming traffic. This happens even when the vehicle is centered in the lane. This is extremely dangerous because it can cause an accident. When using cruise control, the lane assist comes on automatically which is extremely dangerous because the vehicle is going at high speeds on the highway. The dealership is aware of the situation. Both the mechanic and the salesman have driven the vehicle with me and experienced the problem. Additionally, the salesman and I drove another 2025 palisade and the lane assist problem was present in that vehicle also.

The windshield (visibility system) on my 2025 Hyundai Tucson (VIN: [XXX] ) was cracked on [XXX]. I immediately contacted the dealership where I purchased the vehicle (in New York), and later local Hyundai dealers in Florida where I now reside. I was informed that the windshield is on a nationwide OEM backorder with no estimated time of arrival (ETA). As of August 6, 2025, the part remains unavailable, and the vehicle has been inoperable for 57 days, parked in my garage. The crack makes the vehicle unsafe to drive, and due to Advanced Driver Assistance Systems (ADAS) such as lane keeping assistance and forward collision warning, the windshield requires proper OEM calibration post-installation, which cannot be performed until the correct part is secured. The issue was confirmed by multiple Hyundai dealers and 3rd-party glass installers, all of whom indicated they are unable to acquire the correct windshield due to Hyundai’s ongoing parts shortage. No resolution has been provided by Hyundai corporate. Although one vendor was referenced by the dealer, they too did not have the part available locally. Hyundai has offered limited rental reimbursement, but not enough to cover costs during this extended downtime. No inspection has been conducted by the manufacturer or insurance company beyond initial confirmation of the damage. No warning lights or messages preceded the incident — the issue is entirely due to the unavailability of a critical OEM part, making the vehicle unsafe and unusable. I am paying monthly for a financed vehicle that cannot be driven due to a manufacturing and supply chain failure beyond my control.
