Kia Tellurides produced between Feb and Dec 9, 2019 had software issues related to the torque converter solenoid pressure (too low to securely mate torque converter clutch) and over-sensitivity trouble code P0741, which indicates torque converter clutch slip. Kia fixed this software issue for the remainder of 2020 production, starting Dec 10, 2019. Kia also issued TSB TRA089 in April 2020 to reflash the transmission control unit (TCU) but would only do this on vehicles with an active check engine light (CEL), rather than reflashing all affected vehicles with proper TCU firmware. Many customers, including myself, were unaware of the clutch damage that took place as a result of outdated TCU firmware and drove our vehicles with constant micro-slip events, which prematurely wears out the torque converter clutch. This is why there are so many torque converter failures on 2020 Kia Tellurides between 80~120k miles. I now have a 2020 Kia Telluride with 126k miles built on Dec 6, 2019 (3 days before the TCU firmware was fixed), and my torque converter is slipping badly. It is now a safety concern because the vehicle is unpredictable and may or may not properly engage the torque converter. The torque converter must now be replaced and fluid flushed; however, metal shavings also have negative impacts on the transmission and could require a full transmission replacement. This issue is not normal wear and tear. It is a known clutch slipping issue that Kia chose not to address until customer vehicles break down catastrophically. Now owners are on the hook for expensive torque converter and transmission repairs, while this expense could have been avoided with a TCU reflash that Kia knew about for nearly 7 years - since Dec 10, 2019. After this date, vehicles came stock with updated TCU firmware that applied sufficient clutch solenoid pressure to prevent constant microslip events and premature torque converter clutch wear out.

There was a low-speed collision with a deer (approximately 10-15 mph). The vehicle continued to run fine after the collision and we were able to drive it home. After the next start, the engine was shaking all over and started smoking from behind the engine. The battery was disconnected but it continued to smoke. After further inspection, we were able to find a fire and extinguished it using a fire extinguisher. We had issues with this car prior to the collision where the engine would misfire after the car would get wet, but would only produce temporary codes. This was checked out by the dealer and we were told there's nothing that they can do. A few weeks prior to the collision it happened again and the check engine light went to a confirmed/permanent code and it was related to cylinder misfires. If we would not have had a fire extinguisher or had been able to roll it away from the house, the occupants, vehicle, and house would have been in danger of the fire. The source of the ignition has been confirmed to be the ignition coils, but the root cause of this has not been determined and it has just been assumed that it is related to the collision, without an actual root cause identification.

the federal safety agency Vehicle Safety Complaint – 2021 Kia Telluride I am the original owner of a 2021 Kia Telluride with approximately 78,000 miles. My vehicle has experienced recurring mechanical and drivability concerns, including an intermittent check-engine light, a previously reported camshaft-related diagnostic trouble code, and hesitation during acceleration. Of particular concern, there have been instances when I have pressed the accelerator pedal and the vehicle has hesitated before responding. This delayed acceleration creates a potential safety concern, particularly when entering traffic, merging, or navigating intersections where predictable engine response is essential. Additionally, the vehicle has exhibited rough operation while reversing and unusually harsh engine behavior when the automatic engine stop-start system engages. Despite multiple visits to a Kia-authorized dealership, including a monitored 1,000-mile oil consumption test, these concerns remain unresolved. The dealership advised that the vehicle passed the oil consumption test but subsequently recommended a dynamic engine cleaning procedure. I was informed that the technician was approximately 85% confident this procedure would resolve the issue. However, no definitive explanation of the underlying mechanical problem was provided. I have requested written documentation of the diagnostic findings and the basis for the recommended procedure. I have also opened a formal case with Kia America Consumer Affairs regarding these unresolved concerns. I am submitting this complaint because I am concerned that the recurring acceleration hesitation and related engine symptoms may indicate a safety-related defect that has not been adequately identified or resolved. I respectfully request that the federal safety agency document these concerns and evaluate whether similar complaints involving 2021 Kia Telluride vehicles indicate a broader safety issue.

While driving the vehicle on the highway attempting to pass a vehicle at 75 mph the car unexpectedly shut completely off. We had to swerve between 2 vehicles narrowly avoiding an accident and the car would not turn back on. Towed to Kia dealership and was told it was simply a sensor that "talks" to the key fob which caused the car to shut off without warning. Dealership claimed it was fixed but there was no warning lights or notice of the failure. Since the dealership "fixed" the issue now the car is continuously running a check engine failure code and now the dealership claims it's the catalytic converters failing and needing to be replaced. Vehicle was inspected by the Kia dealership that it was purchased from.

My 2020 Kia Telluride experienced progressive and severe engine oil consumption that ultimately required a full engine replacement. Beginning well before the failure, the vehicle required frequent manual oil top-offs between scheduled changes, including on longer trips. No low-oil warning light, check-engine light, or oil-pressure warning ever illuminated to alert of critically low oil levels. In late March 2026 an independent service center replaced the engine oil filter housing and related gasket after an oil leak was observed; an axle damaged by oil spray was also replaced at that time. Shortly afterward the manufacturer issued a warranty extension covering oil-filter-housing gasket leaks on 2020–2025 Tellurides, extending coverage to 15 years/180,000 miles for that specific condition. Despite the housing/gasket repair, the excessive oil consumption continued. Several weeks later the vehicle lost power and broke down while being driven. It was towed to an authorized Kia dealership. Technicians inspected the vehicle, confirmed heavy oil consumption (noting the engine had been requiring large amounts of oil nearly weekly with no external ground leaks observed), and diagnosed catastrophic internal engine damage. They recommended complete engine replacement at a quoted cost exceeding $13,000. The dealership also inspected the oil-filter housing area under the recent warranty extension but determined the engine damage itself fell outside that limited coverage. The oil-consumption problem and resulting engine failure create a clear safety risk: sudden loss of power or stalling can occur without any dashboard warning, potentially while the vehicle is in motion on public roads. The failed engine and related components remain available for inspection. The condition has been confirmed by both an independent service center and an authorized Kia dealership. Similar oil-consumption and engine-damage reports have been widely noted among other owners of the same model.

Unfortunately, beginning in June 2025, I experienced a serious engine problem. While driving, the vehicle began sputtering and stalled twice in traffic. I immediately brought it to the dealer, where I was told the engine had no oil, despite no prior warning of abnormal oil loss (no engine warning lights and no leaks). The service department added oil and initiated an Oil Consumption test. On October 4, 2025, the same problem occurred again. While driving, the Telluride began sputtering again, and the dealer again determined that the engine had no oil. I was charged for another oil change and instructed to complete another Oil Consumption test. During this process, the maintenance supervisor acknowledged that excessive oil consumption was a known and serious issue affecting Kia Tellurides and other models, and explained that engine replacement was the appropriate solution. I also observed another Telluride at the dealership undergoing the same type of engine repair. After completing the required testing, the dealer ultimately installed a rebuilt engine in my vehicle to address the excessive oil consumption problem with the original engine. I am now back in the same situation. On September 8, 2026, less than one year after the rebuilt engine was installed, my Telluride once again began sputtering while I was driving. I brought the vehicle to back to the dealer on on September 9, 2026. The service personnel again told me there was no oil in the vehicle, despite it being well within its recommended oil-change interval. More importantly, I was informed that the rebuilt engine currently installed in my vehicle is suspected of having the same excessive oil-consumption problem as the original engine. After following the instructions on yet another engine recheck and Oil Consumption test, I 've been told that the engine is burning oil at an exponential rate.

I had my vehicle checked for oil consumption for it failed the test. After Kia approved an engine swap an engine light came up with faulty O2 sensor. Not just one but both O2 sensors. Replaced both sensors but the problem persist. Kia changed the engine harness with the assumption that the technician damaged the harness while installing the engine. My vehicle has been at the dealership for four months and I honestly don’t know what to do.

The contact owns a 2020 Kia Telluride. The contact stated that while driving approximately 15 MPH, the vehicle hesitated to maintain automotive power. The check engine warning light was illuminated. The vehicle was previously repaired at a local dealer for an unknown recall associated with an engine oil leak. The vehicle was towed back to the same local dealer where it was diagnosed and an engine flush was suggested, and the contact was informed that six fuel injectors needed to be replaced as a possible repair. The manufacturer was made aware of the failure, and a case was filed. The approximate failure mileage was 109,000.

My engine failed from burning oil, even though the car has been maintained its whole life, 14 documented oil changes, roughly every 5,000 miles. • Jiffy-lube shop found the crankcase completely bone dry, only 4,344 miles after the last oil change. No reading on the dipstick. They added 6 quarts. Engine was knocking before and after. • No oil warning light ever came on, and no low-oil warning, just a check engine light and the knocking. • Towed same day to an independent shop. They found code P0524 (engine oil pressure too low) and say the internal noise is probably a rod bearing. Engine needs to be replaced. • The car goes into limp mode while driving. On the highway it dropped from 60 mph to 20 mph in live traffic with no warning. I couldn't safely get to an exit. • That's about 1.4 quarts per 1,000 miles, Kia's own bulletin ENG222 calls 1 quart per 1,000 excessive. • The car is not drivable, hasn't been repaired. This happened around 3 months after purchasing it second hand. Lots of other 2020 Telluride owners are reporting the same oil consumption problem.
