2021 Kia Telluride Suspension Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2021 Kia Telluride owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2021 Kia Telluride. The contact stated that the passenger's side drive shaft boot was leaking. The steering and mileage were affected by the failure. While making a turn, the steering wheel was readjusting. The accelerator pedal was depressed; after the pedal was released, the pedal jerked. There were no warning lights illuminated. The vehicle was taken to the local dealer, who confirmed there were no open recalls associated with the VIN. The brakes were reprogrammed. The vehicle was diagnosed, and it was determined that the front boot was leaking, and the axle and tires needed to be replaced, and an alignment performed. The vehicle was not repaired. The vehicle was taken to another local dealer, Kia Mentor (9090 Mentor Ave., Mentor, OH 44060); who provided the same diagnosis. The vehicle was not repaired. …

There is an ongoing problem with the NIVOMAT self-leveling shocks on every model year of this vehicle. The problem occurs at nearly every speed but is more noticeable at lower speeds (35mph or less) while going over uneven terrain or hitting small bumps. The vehicle produces a clunking noise from the rear of the vehicle and there is no cushioning or rebounding from going over the bump or uneven terrain. Instead, there is more of a jolting knock when hitting small bumps and a constant bouncing around/floating feeling while driving over uneven terrain. This is dangerous because passengers and cargo in the vehicle gets bounced around and the vehicle gets harder to control especially at higher speeds. Many of these shocks are failing early in the life of the vehicle. Mine is at 27K miles, however I believe the problem started before and probably closer to 18-20K miles. …

The rear frame of my 2021 Kia Telluride has a broken weld. This is a structural failure that compromises the safety and integrity of the vehicle. The Kia dealership mechanic who inspected it confirmed the weld was defective and also stated they have heard other Tellurides with the same issue. A broken frame weld poses a serious risk to vehicle occupants in the event of a crash and may affect handling, towing, and long-term durability. This appears to be a recurring defect and should be investigated as a potential safety hazard. After several trips to the dealership, for the loud metal to metal type bang, they have replaced struts, rear stab links and shock absorbers. On 9/17/2025 the mechanic was given a list of items to inspect and the dealership informed me that one of the items on the list was to check the frame welds. …

My 2021 Kia Telluride has suffered two consecutive component failures of the rear suspension's self-leveling shock absorbers. This component is the exact subject of Kia's August 15, 2024 Extended Warranty Program (WTY040), which acknowledges a widespread engineering defect causing premature rear shock failures. The factory-installed original shock failed previously. The official Kia genuine replacement part (redesigned by Kia to permanently address the original defect) has now failed prematurely under the exact same mechanical conditions. The failed replacement component bears a manufacturing date stamp of 11/2023. Kia America Corporate is utilizing an administrative loophole regarding the component's manufacturing date code to deny safety coverage, actively refusing to honor or remedy the failure of their own redesigned replacement part. …

I have 2021 Kia Telluride with 38000 miles on it. When I wash my car, I normally wash the roof and in order to do that I put one foot on 3 step ladder and one foot on the back tire. I always had a plenty space above the tire and under the fender and I could stand up on the tire while I was washing the roof. On my last wash after the harsh winter weather, I notice I can not place my foot on the tire anymore. I google the height from the bottom of the fender to the ground and I noticed is way down. I read on Google that is covered by KIA for 15 years or 180000 miles. I contacted the Riverhead Kia and they replaced the shocks. When I came out of the dealer I immediately noticed the height has not been improved. I informed the service advisor, he said that is not going to be like a new 2026 vehicle and it should be Ok. …

In the summer of 2023 I started hearing a clunking noise from the rear of the vehicle that became louder when going over bumps. Took the car to the dealer and I was told the rear shocks were bad and needed to be replaced. Aug of 2023 the original shocks on the car were replaced which was premature for the average life of shocks. Then months later the same things started and I had a puddle of fluid on my garage floor. I took my vehicle back into the same dealership in June of 2024 only to find the rear shocks had failed again. This time in less than a year. Now in September, I can feel the back end getting loose when I go over bumps, which is what happened previously before the shock completely failed. The ride is continuing to regress. Up until this I thought I would go into another Telluride but the lack of longevity in the ride comfort has changed my mind. …

Around 65,000 miles Rear self-leveling shock absorbers started making clunking noises, now they're extremely stiff, not compressing with weight, even small speed bumps affect the rear of the car, rear/cargo bouncing up violently over mild speed bumps, rough on 2nd/3rd row passengers. the standard front shocks which are still good. The problem, reproduced on a drive, verified by a dealership service department tech. Local dealership reported problem to Kia, and Kia offered to cover parts but I'd be charged over $500 labor. A premium package car shouldn't have such a rough ride because of failing suspension parts. Kia should fix the rear shock issue on the 2021 Tellurides ordered w/ "self-leveling rear suspension" under a recall. Thanks for your attention.

. Cannot drive the vehicle because the rear end bounces up and down and side to side violently making it difficult to control ehile driving. Kia dealership said rear shock absorbers need replacement and Kia warranty does not cover $1800 repair. Kia dealer said this has happened previously. There are many comments on the internet from other Kia Telluride owners about the same problem. I opened a case with Kia Motor Company requesting they cover a portion of the repair given the numerous online complaints, and the obvious safety risks. They refused. Kia is clearly installing defective parts on this vehicle.

I wish to amend my previous report dated 6/22/2026. #11745783. IT is is cv boot on the right side. I had a dealer do the repair. It is not under warranty, If you follow the Kia Telluride complaint page son FB, others have had the same issue. It cost $777.61 to repair. It should not need to be repaired at 72k miles. That is a third of the expected life expectancy. Thank you for considering this safety matter.

Rear shocks unstable. When on rough roads or small imperfections in the road it's hard to control vehicle and items/people get abruptly jostled. The dealership has been notified but says it's not a recall and will look at it but can only take pictures and send it off to main office. No warning of this failure.
