2023 Hyundai Palisade suspension problems

“I have a 2023 Hyundai Palisade Issue: At low speeds under 20 MPH, on bumpy, rough surfaces, more noticeable when turning (left or right) and going on an incline (up or down), there is low level noise from the backend undercarriage of the Palisade such as clunking or thumping noise. The failure is persistent and gotten progressively worse. The failure was duplicated at the dealer. This is a known issue from Hyundai. See Technical Service Bulletin 26-SS-001H created on May 2026 Hyundai has formally acknowledged this rear-shock noise problem. Technical Service Bulletin 26-SS-001H, Warranty Extension Z12. Problem: Certain Palisades may have a clunking or thumping noise from the rear while driving over rough roads, caused by worn self-leveling rear shock absorbers. In the Technical Service Bulletin 26-SS-001H it says Please note that for the first repair, replacement of both rear shock absorbers will be covered by this warranty extension. For subsequent repairs, one or both rear shock absorbers will be covered depending upon the impacted side(s). I reviewed the Hyundai TSB 26-SS-001H closely. I think I have a solid basis for a firm escalation email, especially…”

“I was driving and stopped at the tunnel for traffic. My car shut off and wouldn’t turn back on. It seemed to have overheated. After about ten minutes, it started again. I was told it was told the oil pump controller affecting the stop and go on my car. Priority Hyundaii in [XXX] didn’t didn’t have the part to repair it. Now they are refusing to repair it.”

“Two simultaenous problems happened: 1) loud clunking/thudding during low-speed turn. 2) Clunking/knocking/rattling noise from suspensions when going through uneven grounds. This both things happened before 20,000 miles. Had AWD coupling and rear differential unit replaced under warranty regarding problem 1). Had rear shocks replaced under warranty regarding problem 2). Found there has bben TSB issued related to 2), for older models, TSB 25-SS-004H but not for this year of models. Those two exact problems started again at about 40,000 miles. Had vehicle checked at 50,500 miles recently. Regarding problem 1), the dearship found issue with AWD coupling, stating faulty parts, drive shaft seal was 1/8" off and materials are fused. Replaced AWE coupling, and ECU program update. After program update, I do not see the power distribution monitor anymore from my dash. The program update should turned it off for some reason that I do not know. I have no clue that AWD module is working normal as I cannot see the power distribution action anymore. Regarding problem 2), they replaced both rear shocks again. The problem went away for now. This vehicle has been only 50,000…”

“The self leveling shocks have gone bad two times now in a matter of 4 months. The first time we had no major issues but the second time it caused the ABS system to kick in while making a left turn. The dealer said it was caused by the car not sensing the correct posture because of the shocks turning on the ABS system and causing us not to be able to brake for about 10-15 feet. If there was a person or vehicle in the way we would have crashed.”

“I have had to replace tires 5 times since I got the vehicle. The mechanic said there may be a balance issue with the car and it is wearing on the rims/tires prematurely. Currently 63000 miles on car.”
