In August of 2023, Stivers Hyundai located in Columbia, SC replaced the rear shock absorbers on my 2020 Hyundai Palisade Limited due to a rattling and knocking noise in the rear of the vehicle. The noise never completely went away, but was somewhat better. In July of 2024 the noise was back to the same noise as we were hearing in 2023. We took the vehicle to the dealership in August of 2024 complaining of the same noise previously heard. The dealership stated that we needed new shock absorbers (same as which they replaced a year ago) and which only had approx. 20,000 on them. When we explained that they had just replaced them a year ago, they completely dismissed our concern and noted that they needed to be replaced and offered no explanation as to why they would wear out in a years time. At the point we visited the dealership in 2024, the vehicle was no longer under warranty and we were quoted over $3,000 to fix the issue. In looking through other online forums, this appears to be a common issue with this vehicle. My thought is that there is an underlying issues that is causing this to happen that may not be addressed through simply replacing the rear shock absorbers. Maybe there is an issue causing the shock absorbers to wear out so quickly and that issue has not been identified. Nonetheless, shock absorbers should not wear out in 20,000 miles under normal (mostly interstate) diving conditions.
