2020 Kia Telluride

Component/System Failed: Engine — excessive oil consumption and oil leaks leading to complete engine failure requiring full engine replacement. Vehicle is currently at my home and available for inspection upon request. Safety Risk: My vehicle became completely inoperable while in use as my primary family transportation. As a parent of three children this has left my family without safe reliable transportation. An inoperable vehicle also creates safety risks related to emergency situations where transportation is critical. Confirmed by Dealer: Yes. An authorized Kia dealership confirmed the engine defect and approved a full engine replacement. The repair has not yet been performed. Inspections: Vehicle has been inspected exclusively at an authorized Kia dealership where all service and maintenance has been performed. Warning Symptoms: This is the third time this vehicle has become inoperable due to what was previously identified as an oil issue but is now confirmed to be an engine defect. Prior to complete failure the vehicle exhibited ongoing oil leaks and excessive oil consumption over an extended period. AAA roadside assistance was contacted and identified possible starter and battery failure believed to be connected to the engine condition. Additional Note: I have identified NHTSA complaints from other 2020 Kia Telluride owners reporting identical engine oil consumption and failure issues suggesting a pattern defect.

I own a 2020 Kia Telluride currently with approximately 91409 miles. The vehicle has a repeatable transmission issue during acceleration, most noticeable around 40 mph when the transmission shifts. The vehicle shudders/hesitates/jerks and does not accelerate smoothly. This creates a safety concern because the hesitation occurs during normal acceleration and could affect merging, passing, or maintaining speed in traffic. I brought the vehicle to Vision Kia of East Rochester, 201 East Linden Ave, East Rochester, NY 14445 on 2/4/26 at approximately 88067 miles. The Kia service manager/technician duplicated the concern during inspection/road test and stated that the issue is related to the torque converter damper clutch. However, I was told the dealer would not repair the vehicle unless a warning light/check-engine light comes on. No warning light is currently illuminated. I am reporting this because the transmission defect has been observed by the dealer while the vehicle is still under warranty, but no repair has been authorized. I am concerned that the condition may worsen and could cause delayed acceleration or unsafe drivability.

Following a recent $9,000 engine replacement performed by an authorized Kia dealership, my vehicle suffered a catastrophic, simultaneous mechanical and electronic systems failure while in operation. Without warning, the vehicle triggered the Knock Sensor Detection System (KSDS) and entered "Limp Home Mode," severely restricting vehicle power. Immediately following this, the vehicle experienced a total loss of essential safety and driving controls: Steering Failure: The power steering completely locked up, creating an imminent crash hazard. Dashboard & Gauge Failure: All dashboard warning lights illuminated simultaneously, and the speedometer completely stopped functioning, leaving me unable to monitor vehicle speed. Powertrain & Shifting Malfunction: When brought to a stop and placed into "Park," the vehicle's electronic systems failed to recognize the gear change, indicating on the dashboard that the vehicle was still in "Drive." This created a severe vehicle roll-away risk. Ignition Failure: The vehicle completely refused to shut off or power down when the ignition button was pressed. This event represents an extreme safety hazard involving sudden loss of vehicle control, steering immobilization, roll-away risk, and primary electronic communication failure immediately following a major manufacturer warranty/recall repair. The vehicle is currently un-driveable.

I was driving down the interstate when all of a sudden, I hear a bang, and my power went crazy, couldn't push the gas at all, my car was suddenly shut off. We coasted to the side of the interstate and got out to see a pile of oil underneath my car. Called a tow truck to help us and he found a massive hole in the engine block / oil pan - catastrophic engine failure. I have 117k miles on my car BUT I have kept up with maintenance on this vehicle. There should be no reason for this to happen. This put my family in immediate danger.

In February 2026 my vehicle had a front parking sensor error. When i broght it in for repair my shop found a corroded cable in the front parking sensor harness. The mechanic was able to repair the harness...$280 In May 2026 my vehicle this time had a rear parking sensor error. The shop discovered a rear parking sensor harness completely corroded & had to be replaced along with one parking sensor...$715. (The invoice does not include the cost of the sensor as it was purchased separately when diagnosing the front sensor failure) I purchased this vehicle in January 2020 & it has spent its entire life garaged in New York State or in Florida. It has only been driven one winter(2025-2026) in NY State. This is unacceptable! The cost of rear harness alone including tax was over $300!

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.

i was driving home from work my 2020 Telluride shut off at stop light. I was able to turn the car back on and continue my drive after about 30 minutes into my continued drive i started hearing extreme banging noise coming from the front of the car. i then drove to kia dealership where they had inspected and diagnosed as the engine had failed and i would need a whole new engine.

Kia radio goes out randomly, will cut off and fails to turn on when the vehicle turns on. It will make a loud noise like an old car being scratched and then it turns off. The radio will freeze up and it affects my digital speed control. I have reported multiple times to my dealership with no help. It has been happening since I purchased the vehicle in 2023.

Transmition- I started bringing it into the dealer around 80,000 miles because it was slipping and bucking (gears). Allegedly, they could provide warrenty coverage but could duplicate the problem. It is doing it more frequently and hesitates (drastically) which can cause an accident from behind. Yes, it was reproduced but as I stated, I was told, "They couldn't do 'anything about it'". It has been inspected multiple times at Kia prior to 100K warrenty At one point, my check engine light kept coming on, then it just went off. There seems to be some major faulty component with this make, model and year. I have read many very similiar complaints, online and there seems to be chronilogical issues/problems that arise at certain miles. Everything I have read, it the exact same situation I have been having which is just geting worse by the day. However, I was blatently informed by Kia, "They would not replace the transmition unless it went." I think that is totally ridiculous, you wait until it goes and can cause an accident before you will fix/replace the part. I also read and heard from multiple mechanics that it could be the "failed torque converter" which was never mentioned from the dealer. I have also had issues with the CV axle and oil plastic housing.
