2020 Kia Telluride Suspension Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2020 Kia Telluride owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2020 Kia Telluride. The contact stated that while operating the vehicle, the "Electronic Parking Brake" warning light remained illuminated, and the vehicle failed to properly accelerate. The vehicle was taken to the local mechanic who diagnosed that the "Parking Brake Connector" had fractured. The vehicle was not yet repaired. Additionally, while driving at various speeds, the vehicle was shaking and vibrating abnormally. The vehicle was taken to the local dealer who replaced the rear shock absorbers, rear sway bars, rear control arms, and the motor mounts. The local dealer also discovered that the oil pan and oil filter had cracked. The vehicle was repaired. The manufacturer has not yet contacted. The failure mileage was 50,000.

The 2020 KIA Telluride was purchased with the "tow package" which included "self-leveling" rear shocks. The self-leveling rear shocks failed early and has created a safety concern with braking/handling/steering in addition to comfort in ride. Concern with the shocks began around 60,000 miles (roughly Jan 2023), but there was no indication of shock failure or leakage. Our independent service center/mechanic told us the shocks looked fine and that typically shocks should never fail this early. We just assumed the ride was rough and even after replacing tires, the ride never improved. As it progressively worsened, the local certified KIA dealership has now inspected and verified that both rear shocks have failed (leaking and rusting) and that the ride is unbearable (the vehicle is over 77,000 miles now). …

Car has been brought to KIA for transmission issues multiple times and the associate tells me to just tighten the gas cap to get the light to go off. The car is not shifting properly and will "jump" or "lunge" forward while driving. I have noticed that the RPM's will jump and bounce around, seemingly down shifting, then shift again, and then down shift again, which causes jerking motion. The reason I initially took the vehicle in was for a "shake" or "wobble" when accelerating up a hill (semi steep incline) or at freeway speeds (55-70MPH). In these instances, the vehicle will have a hard time shifting and temporarily lose momentum causing concerns for me and other drivers on the road. The transmission light will go on and I call KIA to be told to tighten the gas cap. I recently brought it in for the third time and they diagnosed something different. …

I am filing this safety report regarding my 2020 Kia Telluride, which currently has approximately 133,000 miles. The vehicle is experiencing severe internal oil consumption, burning through multiple quarts of engine oil rapidly between normal service intervals without triggering any dashboard warning lights, creating a high risk of sudden engine failure or stalling at highway speeds. Additionally, the vehicle is losing coolant at an accelerated rate, risking severe engine overheating. Furthermore, the suspension system has been a recurring safety nightmare; the shocks have failed and been replaced twice, and a critical structural defect caused the tires to rub directly against suspension components while driving, prematurely destroying the tires and severely compromising vehicle stability and steering control. I do not feel safe driving this car or transporting my kids everyday. …

#1 Rear shocks have been replaced 5 times (beginning November 2021-September 2024) after bringing the vehicle in 7 times due to clunking. After dealing with Kia directly they agreed to cover costs. Clunking was resolved shortly but started again a couple months later. #2 Recently the car began locking up while in operation, while accelerating, but no code was detected. Transmission was flushed (December 2024) and one month later same type of lock up began happening again, this time the check engine light came on (January 2025). Code indicates Torque converter clutch is off. Dealer will now try to fix the issue. Car is available for inspection. Problem #1has been reproduced by Kia service at the dealership.Problem #2, since code was detected dealer will inspect and hopefully be able to fix. This car is just over 5 years old with less than 70,000 miles. …

The rear self adjusting shocks do not work - the smallest bump jolts anyone in the car, even at the slowest speeds (10 mph), NOTHING works to keep bumps from feeling like there are no shocks at all or they are frozen (and I am accustomed a Jeep Wrangler's rough ride). My son has an LVAD implanted in his chest, attached to his heart that keeps his heart pumping, and every ride to the doctor is like the car is trying to yank the LVAD off his heart, causing him great pain. I can't stop the car from hurting him!! The dealer replaced the cap on the shock but it did NOTHING to help. I have another appointment, they admitted there were problems with the shocks, and my car isn't even included in the TSB!!! They fit me in for an appointment in October but said they had received word the manufacturer might be going to try something else. …

Took my 2020 kia telluride for emission software update after being notified by the the dealership. Two days later my check engine light keeps coming on and off. I called the dealership and the said to bring it in only if the light is on. The next day my engine light once again keeps going on and off but now also my battery light keeps flickering on and off as well. My car is also slow to idle and when going slow speed my steering will shake. Also when I first start my car in the morning by RPM needle goes up and down as well as my a/c blow strong and then low matching rpm needle. My car seems to pull on hills it feels as there is not enough power to make it up the hill and my car also shakes. My car was running perfectly fine before I took my car to the dealership for this emission software update.

My Telluride mileage just passed 30K. The rear suspension seems like no shock-absorbing capability since the car is so bumpy. The front suspension looks fine though. I went to a service center, but they told me they couldn't find any symptoms. I was shocked when I heard about that because I could see an apparent difference even with pushing it with my hand! Strangely, there's no squicking noise. And they told me no oil leakage. But, it's bumpy. I'll try to visit the service center for the recall and ask them to check the suspension together with me. The rear suspension has the optional self-leveling shock that has a noise concern. I may need to replace them with a normal suspension.

My rear struts are leaking and Kia is refusing to repair them. I know that Kia recalled self-leveling struts for my make, model and year, but I'm told that my version doesn't have those struts. Even though I'm at ~85,000 miles now and it's out of warranty, I believe my struts failed much earlier and it didn't become noticeable until now. Moreover, in searching the internet, many other owners of Kia Tellurides are facing this issue. I would like Kia to be investigated for failures related to rear struts for the 2020 Kia Telluride to see if this is a parts defect.

Severe vibration at highway speeds between 60-80 mph on intermittent basis.
