2025 Hyundai Palisade

Following a dealer transfer assembly replacement under warranty on a 2025 Hyundai Palisade, technicians failed to perform a post-repair alignment and left the driveshaft unseated. The 2nd dealership we went to subsequently misdiagnosed the resulting suspension warping as 'tire overinflation' on June 5. As a direct result, my family unknowingly drove thousands of highway miles across state lines to MT and SD with an unseated drivetrain and a completely loose structural subframe bolt, presenting a severe risk of catastrophic suspension/steering failure at highway speeds. They misdiagnosed 3 times and claimed to do test drives each time, but each time we got in the vehicle, we heard the noises, they said they could not hear. Had a mechanic ride with to verify the noise, and only diagnosed the driveshaft unseated afterward, but not the subframe bolt, which the structural defect was finally confirmed on August 25, the 4th time at the 2nd dealer.

I am reporting a safety-related defect with a 2025 Hyundai Palisade SEL. Within days of purchase (December 14, 2024), I began experiencing abnormal noise and vibration from the rear of the vehicle. The issue consistently occurs at highway speeds (45–55 mph) and over bumps. The problem has been present since the first week of ownership and has worsened over time. Multiple inspections confirmed the issue: •Selling dealership dismissed it as “normal tire noise” without proper diagnosis •Second Hyundai dealership confirmed severe abnormal wear (cupping) on all four tires •Independent inspection (Firestone) confirmed uneven tire wear, alignment out of specification, and ongoing vibration Despite early reporting, Hyundai Motor America has refused to provide a root cause diagnosis or take responsibility. They denied tire replacement, attributing the issue to tire wear. This explanation is not valid. Tires do not develop severe cupping shortly after purchase without an underlying defect such as improper alignment or suspension issues. This condition creates a safety risk: •vibration reduces vehicle stability at highway speeds •uneven wear increases risk of tire failure The issue affects all four tires and was present almost immediately after purchase, indicating a likely manufacturing or setup defect. The problem has been confirmed by multiple service providers but remains unresolved. The vehicle is not safe to operate under normal driving conditions. I request immediate investigation into a potential manufacturing defect affecting vehicle safety. Hyundai has been aware of this issue since the first week of ownership and failed to take corrective action. Despite multiple documented inspections confirming abnormal tire wear and vibration, no root cause diagnosis or repair has been provided. This raises serious concerns about a potential systemic defect affecting vehicle safety.

This vehicle on multiple occasions per week will have what my husband can only describe as the ABS incorrectly kick on. It happens in our driveway, rocky parking lots or streets that aren’t even. The vehicle shakes uncontrollably and the brakes can not be pressed when it happens. In the worst situation we ended up over a curb, luckily the curb seemed to help stop us before potentially hitting a post office. No lights come up on the dashboard and it isn’t easy to replicate as it happens randomly - usually at lower speeds - when coming into a stop. Our safety is put at risk every time we drive, not knowing if the issue will happen; and not being able to brake or remedy the issue. This is not a one time incident - this happens multiple times a week.

My 25 Pallisade front end/front wheels shake violently when braking and hitting a bump at the same time. It shakes so hard my steering wheel shakes also. It can happen when braking hard, soft, small bump, big bump, it doesn’t seem to matter. It is brand new and I took it into the dealership when there was about 1500 miles on it. They didn’t find anything wrong.
