For the past year to year ? I have brought my car in for concerns with idle, hesitation when accelerating, stalling out, etc. This has put me in compromised situations when in traffic, at stop lights and when trying to accelerate to get on the highway. I was told it was fine, until it was not. Now my engine needs to be replaced. What I discovered in my car was their worksheet on issues that they never shared with me. Identified issues on this report: Fault Code 6, PO300400 - history, cylinder misfire, PO30500 - history, cylinder misfire PO34100 When going back for a 'simple' 1000 mile oil check, I was told there was not enough oil loss to identify concern. When I checked my own oil after another 1000 miles, KIA then pursued. In researching, there is a history of these engine problems and engines needing to be replaced with KIA. This is unacceptable and has compromised safety and any value I hoped to have with my car.

History of engine randomly lurching/ hesitation when shifting. Have brought car in when it stalled out while driving, or at light. Largest problem now is oil leaking excessively. KIA has not been forthcoming on their history with this issue on 2020 Tellurides. Have been dealing with this the past couple of months and needed to bring it in for 'checks'. Service tech said that ? Quart of low oil after 1000 miles was not enough for KIA to flag; told me to come in at oil change time. He said I did not need to worry as it was still covered under 100,000 warrantee. After checking it myself after driving another 1000 miles, I found that it was low. I brought this in for immediate concerns. I was told to 'wait' as my Service Tech was not there that day. He called me the next day to tell me I should bring in when I can so they can write up an 'approval ticket' for KIA. I brought in the following week. Again he was off. I spoke with another tech who told me it was low 2 ? Q of oil - this was a week later. I now have to wait for KIA to 'approve'. I was told this could take a week or longer.. I need my car. I asked for a rental and was told I may have to pay for it. This is frustrating and disturbing. I am told by other tech that I will probably need a new engine and I should not drive my car until it is addressed. This car is 4 ? years old and has less than 70k miles.

Vehicle burns oil, current mileage at 169k. User manual indicates 7500-10000 miles between changes, I am original owner. Dealership service set for 5k intervals since purchase and done on time. At 99k noticed noises from engine, light rattling but couldn't replicate and couldn't pinpoint at dealership service. At 112k noticed burning oil and rattling noises when accelerating from stop. Changed to 3k oil change intervals, began using premium fuel. 1quart of oil at 0-1000 miles from oil change (had a consumption test at dealership and confirmed "normal" at 112k), sub sequential mileage burns more than 1quart between 1k intervals, can easily burn through 4-5quarts between 3k oil changes. Oil smells slightly like gasoline closer to oil change time. Outside mechanic confirmed rattling as detonation. Concerns of oil not "burning" but mixing with fuel either through oil vapors getting through PCV valve and diluting fuel octane causing rattling. Knock sensor suppresses from causing engine damage, but still happens. Fuel may be getting into the oil, not sure how, but wouldn't explain detonation. No codes, no other issues. Only check engine light since rattling noticed at 99k was failing O2 bank 2 sensor which was replaced by licensed mechanic with OEM parts. The amount of additional oil maintenance and changes were not disclosed on expected maintenance costs sheet posted on vehicles, nor is it communicated in the users manual. Personal opinion is the additional maintenance between changes is unreasonable, and oil isn't "burning" but leaking into the combustion chamber.

The engine; I took my vehicle to be serviced at the dealership on Feb 18,2025 due to it making a weird whining noise when accelerating and/or turning causing the check engine light to appear. I was told then that my vehicle had no oil in it due to a leak in the oil housing filter. I paid $1900 to have it repaired. Then on May 20th I had to take my vehicle back to the dealership to be serviced for the same issue but this time was told that the cylinder 3 fuel injector needed to be replaced. I then paid $1200 for it to be repaired. Here it is July 21st and the same issue has happened with the diagnostic code reading Cylinder 3 fuel injector and the vehicle will cut off at any time while driving. I took my vehicle back to the dealership and was told that my vehicle was 4.5 quarts low on oil and this was due to my vehicle burning oil and I need to replace the engine or trade the vehicle in. My vehicle has only 124,000 miles on it and should not be needing a new engine or repairs. I purchased this vehicle used with 106,000 miles on it and has had it for a year. I have researched the issue and found that 40plus others has had the same issue with the same vehicle. This issue needs to be looked into. I'm unable to upload my invoices as proof of defect. I can email them if you would like me too.

The engine failed catastrophically on a highway bridge putting four [XXX] boys in grave danger. They managed to get the vehicle to the other side of the bridge but it was not safe. Not a single warning light came on prior, and the engine temperatur gauge didn't show anything out of the ordinary. Oil levels were checked and topped off prior to the trip. Oil was changed 9 months prior. A local Kia dealer has confirmed total engine failure. Kia has denied the claim despite being under the warranty period because I cannot supply complete oil change records. Who keeps those? I only keep the most recent one which shows 9 months prior. A quick search shows the 2020 Kia Telluride engine is failing at an alarming rate and Kia corporate offices are practing the deny and delay strategy to dodge responsibility. I will now have to hire attorneys and pay $10,000 to replace their faulty engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In May 2025, I brought my 2022 Kia Telluride to the dealership for an oil leak. They kept my vehicle for a week. Then in June, while driving with my [XXX] son, the engine completely stalled -?" a terrifying and dangerous situation. I returned the car to the dealership, and they tried to point out a bunch of unrelated issues. But once I got home, the car shut off again. I took it back and was finally told that the engine had blown -?" and that this kind of failure "happens all the time" with Tellurides, according to their own words.

Our Kia Telluride had engine failure and a leaking oil pan. There were no warning messages or lamps at all.We noticed a blue smoke coming from the engine upon acceleration and a knocking noise from engine. We took it to a local repair shop and they said the engine was shot. We needed a new engine and a new oil pan as well as an oil change.

Another Kia Telluride reporting the known defect in 2020 Kia Tellurides related to severe and excessive oil consumption that poses a potential safety risk and financial loss. I have recently experienced repeated and worsening oil loss between routine oil changes with no visible leaks or warning lights. The rate of consumption exceed 1 quart per 1,000 miles which Kia defines as -??excessive-?? under Technical Service Bulletin ENG222 (Rev 5). This condition creates a risk of engine failure while driving, especially because there are no warning signs that the engine is about to seize. I am in the process of contacting my dealership but Kia of America declined to acknowledge this issue despite it being well documented and affecting a wide range of Kia engines. I believe this is a safety defect that warrants further investigation due to: 1) Sudden engine failure or stalling from low oil levels 2) Lack of adequate early warning indicators 3) Unreasonable financial exposure to consumers for a manufacturer-related defect 4) A pattern of complaints across similar models/engines. I urge the NHTSA to investigate this matter further and ensure Kia is held accountable for this widespread and dangerous issue.

Had in deals hop several times was told it was on record I was there with the issue but no light on, light came on during travel on interstate and car lost all power Long block blew. Was extremely lucky I didn-??t get ran over by the tractor trailers. Loaded car with kids included. Kia should be reasonable for everything and they are saying no.

This is a follow-up to Complaint #11666572 regarding my 2020 Kia Telluride (VIN: [XXX] ), with urgent concerns about ongoing safety violations and abusive conduct by Greenway Kia East and Kia America. On June 26, 2025, Kia America reversed its prior refusal and agreed to reimburse Uber, rental, and towing costs-?"but only after I filed multiple complaints. Earlier, they claimed to have no influence over the dealership, which had refused all reimbursement after I complained about Service Manager Gina. Worse, on June 27, the dealership responded via BBB telling me to contact Gina again-?"the very person I formally complained about for unprofessional and negligent conduct. This isn-??t just mishandling; it is degrading, retaliatory, and dangerous. Key safety/legal concerns: -?? My vehicle was returned on May 31, 2025, with dangerously low coolant, just days after engine replacement-?"posing a critical safety risk. -?? The service manager dismissed my concerns until I insisted, then acted with open disrespect. -?? Repairs were withheld May 19-?"28 unless I paid $1,833.77, despite warranty coverage. Only after I came in person on May 28 did they reverse and offer free service. -?? I was charged $580.97 for a diagnostic test tied to a manufacturer defect that led to engine replacement-?"still not refunded. -?? The pattern of neglect, retaliation, and deception from both the dealer and Kia America endangers drivers and violates federal safety standards. This dealer has acted with impunity since May 19, 2025. Their behavior is abusive, unsafe, and incompatible with their licensing. I urge NHTSA to investigate whether Greenway Kia East should retain its dealership license. Their conduct undermines public safety and federal standards.

I am writing to formally file a complaint regarding a known defect in my 2020 Kia Telluride, which is experiencing severe and excessive oil consumption that poses a potential safety risk and financial burden. Vehicle Information: -??Make/Model: 2020 Kia Telluride Since ownership, I have experienced repeated and worsening oil loss between routine oil changes -?" with no visible leaks or warning lights in most cases. The rate of consumption is approaching or exceeding 1 quart per 1,000 miles, which Kia itself defines as -??excessive-?? under Technical Service Bulletin ENG222 (Rev 5). This condition not only creates a risk of engine failure while driving, but it also puts owners like myself at risk of uncovered repair bills in excess of $12,000. I have already contacted my dealership, Kia Corporate, and Fidelity Warranty Services, and was told coverage is uncertain -?" despite this being a well-documented issue affecting a wide range of Kia engines. I believe this is a safety defect that warrants further investigation due to: -??Sudden engine failure or stalling from low oil levels -??Lack of adequate early warning indicators -??Unreasonable financial exposure to consumers for a manufacturer-related defect -??A potential pattern of complaints across similar models/engines As a responsible vehicle owner, I respectfully urge the NHTSA to investigate this matter further and ensure Kia is held accountable for this widespread and dangerous issue.

On [XXX], my Kia Telluride received a warranty engine replacement at Greenway Kia East in Orlando, FL. Just two days later, on [XXX], the engine overheated while I was driving with my young child. The temperature warning light came on. I stopped immediately and opened the hood -?" there was no coolant in the system at all. This failure occurred immediately after a major engine replacement, suggesting that the dealer failed to fill or properly check the coolant system. I was left stranded near a daycare and had to call a third-party tow truck because Kia roadside assistance estimated a 90-?"120 minute wait. This put my child and me in serious danger. Despite the dealer-??s clear negligence, I was sent an invoice for $1,833.77, blaming me for the damage. Upon retrieving the car on May 31, 2025, I personally checked under the hood -?" the coolant level was still below the MIN line. When I pointed this out, the service manager said, -??We-??re not required to top it off, but if that satisfies you, we-??ll put some in.-?? This is extremely unsafe and irresponsible, especially after a critical repair like an engine replacement. Later, the dealership even claimed to Kia America that the engine was not replaced under warranty, contradicting their earlier confirmation. This kind of conflicting information, combined with unsafe practices and disregard for basic safety protocols, raises serious concerns about consumer safety and the dealership-??s integrity. To make matters worse, Kia America closed my case ([XXX]) on June 10 without notifying me or giving me a chance to respond. I received only one dropped call from an unknown number, and no voicemail or follow-up communication. A formal complaint was mailed to Kia America on June 11, 2025, and I am currently waiting for their response. On June 12, 2025, I also filed a complaint with the Better Business Bureau (BBB).

I have a 2020 Kia Telluride that I bought brand new from Kia. I have performed regular maintenance on the vehicle and performed the repairs required by any recalls. When my vehicle surpassed 75k miles, the vehicle started having issues with excessive oil consumption. I had my vehicle serviced at 75k miles with the oil changed. When my vehicle was passed 79k miles, the vehicle started stalling, piston misfiring, and engine started vibrating. I took it into the dealer, and they performed diagnostic tests. The determined pistons were working fine but my oil level was very low. This was around 4k miles after my oil change. Kia requires oil changes every 7500 miles. I had the dealer change the oil. Once again, when my vehicle was approaching 4500 miles, the vehicle started to vibrate, piston was not filing properly. I checked my oil level, and it showed very minimal oil on the dip stick. The oil level was well below that was needed for the engine to properly operate. I put closed to 5 quarts of oil to get the engine to the oil level it needed. I am concerned that the excessive oil consumption can lead to the vehicle stalling on the road resulting in collision with other vehicles resulting in bodily injury or harm. According to Kia the oil consumption is fine. How is consuming 5 quarts of oil in 4500 miles fine when the manufacturer states oil changes are required every 7500 miles? The engine itself has a capacity of 6.9 quarts. At the rate my engine is burning oil, I would need over 7.2 quarts of oil to drive 7500 miles. Additionally, having an engine continuously operating with low oil would result in engine damage and thousands of dollars in repairs. The problem I am having in my vehicle is experienced by thousands of Kia Telluride owners. It's the same problem Kia has had in the past with other models. Kia is trying to avoid repairing their defective vehicle and placing the burden on the consumer.

My 2020 Kia Telluride completely stalled on me on my way to work. The vehicle was not smoking and it seemed like it went on accessory mode. I had the vehicle towed to Kia Dealership in Perris to get it checked out and was told by Olivia that no codes were read when doing a diagnostic and that my engine seized. I had purchased an extended warranty through AGWS. AGWS reached out to me to request the vehicle service records which I emailed over as Subject: [XXX] to [XXX] Today March 21, 2024 we receive a call from Olivia stating that my warranty will not cover the cost as they're claiming that we failed to service the car. Our vehicle was services as advised and stated using the appropriate Synthetic oil. I was informed that they would be breaking down my engine to see where it went wrong as there were no codes read. They also stated I had to pay for the engine breakdown $200 per hour and it would most likely take 8 hours (According to Kia). Now, I've gone on many online forum and many people have experienced this problem with their 2020 Kia Tellurides all under $75,000 miles. I contacted Kia Corporate as well but that got me nowhere. I don't understand how these vehicles don't have a recall as of yet for these seized engines. I also don't understand how following the oil recommendations for oil changes is suddenly considered "Lack of service". No one is willing to work with me and suddenly it's my fault that I bought a faulty vehicle. Thank [XXX] I was able to putt to the shoulder of the freeway safely as this is my family vehicle where I drive with my [XXX] and [XXX]. Please investigate as it could be a possible recall.

Vehicle went on accessory mode while driving on the freeway. No codes were read at dealership and now they're claiming its a seized engine. They will not help me out and are claiming my extended warranty will not cover the cost due to the lack of maintenance on the vehicle. Mind you, I did my oil changes as expected using the recommended synthetic oil. Why hasn't there been a recall on this vehicle yet for the danger this creates as this is my family vehicle where I drive my newborn to and from his daycare and appointments. We are very lucky we were able to pull the vehicle to safety and to the shoulder of the freeway before an accident occurred.

The car is a 2020 Kia Telluride. It was purchased in August 2023 at the time it was leaking oil took it back to the dealer and they replaced the housing put in a new filter and said all was good.For a year. it constantly needed oil took it back to the dealer, said that everything was fine. I would be driving and the car would stop. The oil lamp would come on and I would have to drive and put more oil in it every week. I was putting a quart of oil into the vehicle just about weekly because it seemed to be leaking oil and just a dying out. just a few days ago after putting a quart of oil in I-??m driving my vehicle and all of a sudden Smoke comes out of the back a little bit out of the hood. It just stopped all the lights went on the car went dead. Had to call the police get the vehicle towed to the dealer at that point was told the engine had died. They want to put a new engine in the car Which it-??s a five year-old car. It should not need a new engine what is causing it to need a newengine. Ever since I purchased the car, it had oil problems so did the oil lead to engine failure. I know I-??m not the only one that this has happened to every time I would take it back to the Kia dealer. I was told everything-??s fine everything was not fine never got any warning lights or signals, except for when I was driving the car would literally sputter and stop at a light. I would have to restart it and then go get oil.

On [XXX], my wife heard a rattling noise while driving. I verified the rattling noise on [XXX]. On [XXX], I researched online and there are a lot of 2020 Telluride owners that experienced the same issue. They mentioned they had no oil in their cars. I checked the oil that morning and confirmed my wife's car had no oil. I reviewed the manual and checked the oil again according to the instructions in the manual. The car still registered no oil in the dip stick. The car did not report any warning lights. There was no engine light or oil pressure light that came on at any point in time to indicate there was no oil in the engine. Per the instructions in the manual, I drove the vehicle carefully to the auto part store. I purchased and added 6 quarts of synthetic blend 5W 30 oil. After that, the rattling in the engine seized. I sent a text message to Kia in Alpharetta, GA. I spoke with Izzy and explained the situation and requested an appointment to have an oil consumption test performed. She advised that the oil consumption test had a $440 cost and consisted of performing a series of oil changes over the course of a specified time to determine how much oil the vehicle was burning/consuming. She said I could call consumer affairs and I asked her if she was referring to Kia consumer affairs or the national/federal consumer affairs. She verified it was the national/federal consumer affairs and provided me with this number to call 1-888-327-4236 which actually belongs to Kia's consumer affairs hotline. Izzy advised that I had pending recalls in my car and asked why I have not brought the car in. I mentioned that I live in Ball Ground, GA and the nearest Kia dealership to me is the one in Woodstock, GA. However, I stopped taking my car there because I previously took the car there to get the oil changes done and each time I did the car would have a nail in one of the tires a couple days after the service. I lost confidence in the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

My vehicle is using excessive amounts of oil. Every time I drive it, I can smell burnt oil. I took the vehicle to the dealership on 1/24/25 where they found a leak in the oil filter housing. This was repaired (same day) and the oil was topped off per the service report. After smelling the oil smell again, I checked my oil on 1/31/25 and found that the oil was marked between the min and max line on the dipstick. I have reported this to KIA and waiting to hear back. I am reading hundreds of 2020+ Telluride owners complaining of the same issue. I have had no indicator lights.

Our vehicle is 4 years old and has been experiencing excessive oil consumption (a quart every ~600 miles) and extreme shaking at speeds between 20-50mph. After months of trying to diagnose the issue we have been quoted a total engine and transmission replacement. After calling dealerships across the East coast for second opinions, this is a common diagnosis for our vehicle year and model and even within our small local dealership they are seeing other 2019 and 2020 Kia models experiencing failed piston rings. Kia declined our request for corporate intervention to address the issue.
