2020 Kia Telluride

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.

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 have mentioned the transmission each time, but they have focused on other items and not the transmission. I have had the shocks replaced, the tires replaced, alignment performed, and the problem still persist. However, the dealership will not look at the transmission and says that it is the other items, but the issue still remains after fixing the other items. The shock failure caused other items to wear out and the dealer should be on the hook for those items. I have brought the vehicle in dating to last year for the transmission issue with no help from the dealership. Please take action so that we don't lose our lives or put others at risk for injury.

#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. Between these 2 issues I have been in to the service department going on 8 times!

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.

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.

Vehicle began having issues around 60,000 miles. Stutters and slips between 2nd and 3rd gear. When on an incline the issue is much more prevalent. On a steep incline, the vehicle is like lurching it is so prevalent and it feels as though the vehicle is going to give up. Around 45 mph, the vehicle begins vibrating; as speeds increase, the shaking (left to right) becomes increasingly violent. At times, it feels as though the vehicle is going to shake off the road. The issues I primarily when accelerating, and when the gas pedal is released, the shaking slows almost to a stop. Tires, balance, and alignment checked multiple times over the course of the issue and tires are changed seasonally. Took to dealership multiple times to be told there was no issue with the vehicle and it was operating properly. Just over 100k miles, back at the dealership and there is suddenly an issue found. Was told at dealership that passenger side front axle inner race is damaged and needs replaced. Took vehicle to local mechanic since dealership had jerked us around so much over the issues, not repairing, keeping car for extended amounts of time without a loaner vehicle, etc. Local mechanic did a lot of research. This is a common complaint of the Telluride and Kia is aware but is not doing anything about it. Mechanics recreated issue immedately said rear driveshaft had movement it shouldn't and replaced. They also serviced the transfer case and transmission. There is a TSB issued on this, but research suggests that it is not resolving the problems and kia dealerships are not acknowledging the issue until out of warranty and TSB doesn't cover the repairs even though it is faulty manufacturing.
