Certain 2020 – 2024 model year Palisade vehicles may exhibit a clunking or thumping noise from the rear of the vehicle while driving over rough roads. This may be caused by worn rear self-leveling shock absorbers. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, Hyundai is extending warranty coverage for the self-leveling rear shock absorbers under this condition to 10 years / 120,000 miles (whichever occurs first) from the date of original retail delivery or date of first use and is valid for original and subsequent owners.

What stands out
Owners have filed 30 suspension complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 6 model years of Hyundai Palisade in our records for suspension problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Rear suspension failures dominate complaints on 2021 Hyundai Palisades, with owners reporting noises and performance issues between 30,000 and 84,000 miles. The most common failure is rear shock/strut failure characterized by clunking, popping, and knocking sounds, especially when turning slowly or hitting bumps. Owners describe excessive bouncing, a rough or "roller coaster" ride quality, and in some cases visible fluid leaks from failed shocks. Several complaint narratives mention TSB 22-SS-001H (or related TSB 19-SS-003H) addressing rear shock insulator issues—some dealers have stated the bulletin was rescinded, while others reference it as a known defect Hyundai is aware of. Repair costs cited range from $160 diagnostic fees to $2,000 for replacement parts. Multiple owners report repeated replacements at 35,000, 60,000, and 70,000 miles, with one owner stating shocks failed twice within 25,000-mile intervals. Dealer responses vary: some replace components under warranty, others deny coverage after 60,000 miles. A few narratives also mention secondary complaints—seatbelt latch issues, clicking suspension noises that persist after repair, and rough highway vibration—but the rear shock defect is the dominant failure mode across this cluster.

Failure modes owners describe
Rear shock/strut failure with insulator defects
Rear shock absorbers and struts fail prematurely, characterized by clunking, popping, and knocking noises from rear (especially driver side), excessive bouncing, rough ride quality, and visible fluid leaks. Upper insulator caps and mounts are the primary components cited. Multiple owners report repeated failures requiring replacement multiple times within the vehicle's life.
When: 30,000 to 84,000 miles; most commonly reported between 35,000 and 70,000 miles; some failures within first year of ownership
Symptoms owners cite: Loud clunking, popping, or knocking noise from rear when turning or hitting bumps; Excessive bouncing and rough ride, described as 'roller coaster' feel; Vehicle instability and compromised handling; Visible fluid leaks from shock absorbers; Loss of control when accelerating or going over bumps at speed; High-frequency vibration and shaking of lower vehicle portions
Repairs/costs cited: Replacement of rear shock absorbers, struts, and upper insulator caps. Dealers charge $160 diagnostic fee to $2,000 for parts and labor. Some owners report replacements at 35k, 60k, and 70k miles. Alignment work sometimes required but not covered under warranty. One owner reported only insulator replaced; problem persisted and required second visit.
Recalls/TSBs owners mention: TSB 22-SS-001H and TSB 19-SS-003H address rear shock insulator and suspension vibration issues. Some dealers state TSB 22-SS-001H has been rescinded. Hyundai acknowledges this as a known issue in some narratives but refuses repairs on vehicles exceeding 60,000 miles or when warranty has expired. Some owners not informed of TSB existence at point of repair.
Rear suspension vibration and high-frequency shaking
Excessive vibration, rumbling, and shaking from rear suspension, especially on highway driving. Vehicle vibrates and shudders with constant high-frequency motion causing motion sickness in passengers.
When: Early in vehicle life; one case reported immediately after first highway drive on 12/06/2020
Symptoms owners cite: Constant shaking and rumbling with high-frequency vibration from rear; Excessive bouncing and bumpiness on smooth roads; Motion sickness in passengers; Shuddering when accelerating or letting off accelerator
Repairs/costs cited: One narrative references TSB 19-SS-003H for vibration inherited from 2020 model year design; implies design defect rather than discrete repair.
Recalls/TSBs owners mention: TSB 19-SS-003H addresses vibration issues; narrative suggests problem inherited from prior model year design flaw
Suspension clicking and persistent noise after repair
Clicking and rattling noises from rear suspension that persist or recur even after shock replacement. One owner reports replacing insulator three times across two dealerships with noise returning each time; dealer eventually claims noise is 'normal for age and mileage.'
When: Recurring issue; one owner had noise for considerable time with multiple repairs
Symptoms owners cite: Clicking and rattling noises from rear suspension; Noise at low speeds over bumps and speed bumps; Noise that recurs after repair
Repairs/costs cited: Rear shock insulator replaced three times at two different dealerships with no permanent resolution. One dealership claimed noise is normal for vehicle age/mileage after third replacement.

What owners are reporting 2 most recent
I was unable to use my seatbelt because the end that accepts the strap, would not allow the seatbelt to click in to the device. I had to drive without a seatbelt several miles. I tried probably 20 times to get it to click in before giving up. My husband was able to somehow reset the mechanism, and it appears to be working fine at the moment. but I fear I could get either locked in or out of the…
Rear shocks and absorbers have been replaced twice and broken within 84,000 miles.

Common questions
How serious is the suspension problem on the 2021 Hyundai Palisade?
It's a documented issue but not catastrophic. 30 complaints have been filed. Repairs average $900 and most owners catch it before it causes a breakdown.
At what mileage does the suspension typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $900 for suspension repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to suspension?
No active recalls currently cover suspension issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
