2021 Kia Telluride

My 2021 Kia Telluride (approximately 82,000 miles) suffered catastrophic engine failure caused by excessive and abnormal oil consumption. The engine consumed oil at a dangerous rate with no warning lights or dashboard indicators of any kind. The only symptom prior to failure was an unusual engine noise. There was no opportunity to take corrective action before the engine failed completely. This failure occurred while I was driving with my children in the vehicle, creating a serious and immediate safety risk. A sudden engine failure at highway or city speeds — with no prior warning — presents the risk of loss of vehicle control, inability to accelerate out of traffic, and potential collision. The failure has been confirmed by two independent service centers: Vanguard Kia in Arlington, Texas and Christian Brothers Automotive. Both confirmed engine failure. The vehicle and failed components are available for inspection upon request. Kia America has declined to provide warranty assistance or goodwill repair coverage despite this being a widely reported issue among 2021 Telluride owners with the same Lambda II V6 engine. No recall has been issued. Repair cost is approximately $11,000. I am still carrying a loan on this vehicle. I am requesting NHTSA investigate this as a systemic safety defect and consider a mandatory recall.

I own a 2021 Kia Telluride with approximately 111,000 miles. I initially brought the vehicle to a Kia dealership for an oil consumption issue and engine noise. The dealership diagnosed and repaired a timing chain and tensioner issue, stating the vehicle was “working properly” upon return. After picking up the vehicle, I immediately began experiencing electrical warning lights, including the battery warning light and system alerts (blind spot and general warning indicators). I returned to the dealership, where they performed diagnostic testing and indicated a potential alternator issue, but stated it was in a “borderline” range and that the vehicle was safe to drive. Shortly after leaving the dealership, while driving with my family in the vehicle, the electrical system began to fail. Multiple warning lights illuminated, and the vehicle lost electrical function while in motion. The vehicle ultimately became completely inoperable and shut down in a parking lot, creating a serious safety concern. Prior to the dealership visit and repairs, the vehicle had no history of electrical issues, warning lights, or charging system problems. The dealership later acknowledged that the alternator issue was not present when the vehicle was initially brought in. I am submitting this complaint due to the sudden and complete electrical system failure while driving, which posed a significant safety risk. The progression from no prior symptoms to total failure immediately following dealership service and diagnosis raises concerns about vehicle reliability and potential safety defects related to the charging system.

I am submitting this complaint regarding my 2021 Kia Telluride experiencing repeated and dangerous electronic system failures while driving. Kia of East Syracuse (NY) diagnosed the issue as related to the backup camera assembly and communication/network failures. While driving, the vehicle experienced loss of power steering assist, instrument cluster failure, speedometer malfunction, incorrect gear indication, backup camera activation while driving forward, blind spot warnings activating incorrectly, flashing/blank temperature display, and multiple driver assistance system failures. The speedometer displayed 0 mph while the vehicle was in motion and later displayed approximately 40 mph while stopped at a traffic light. The vehicle also became stuck in reverse while backing out of my driveway and would not shift properly, leaving the vehicle stopped in the roadway. Multiple safety systems malfunctioned simultaneously, including Blind Spot Collision Avoidance Assist, Lane Following Assist, Rear Cross Traffic Collision Avoidance Assist, Smart Cruise Control, Parking Distance Warning, and Forward Collision Warning systems. The dealership documented multiple fault codes and stated the dashboard lit up “like a Christmas tree” while the instrument cluster stopped functioning entirely. These failures create a serious safety risk because critical driving information and driver assistance systems become unreliable or inoperative while the vehicle is moving. The failures occur unexpectedly and without warning. Photos and video evidence have been retained, including video of the backup camera activating while driving forward and the speedometer malfunctioning while the vehicle was in motion. I am asking NHTSA investigate these failures as a potential safety defect involving the camera system, instrument cluster communication systems, and CAN network communication failures in the Kia Telluride.

A known Kia Telluride issue arose with the oil filter housing gasket. I came out to find a huge oil leak on my driveway. Not only was the oil really low but it's suspected that it also caused the antifreeze to become low. I had just had the oil change a couple weeks prior so not sure if the technician could have also tightened it too much torque when they tighten the filter cap, causing a crack. It's a known Kia Telluride issue. I was still under 60K warranty but passed the 5 year warranty mark by only 2 months. Since I'd bought my Kia just down the street and faithfully had it serviced there, they service manager tried to be nice and gave me $20 off the $220 bill and told me I should contact Kia since it was a known problem. But when I did they took my case seriously until they learned the dealership gave me $20 off and then proceeded to deny paying for anything. As mentioned, it's a very common issue with this make and model. If I hadn't noticed the oil spot on my driveway, I could have easily driven it until there was no oil (it was already super low) and then had the whole engine blow up. I'm just lucky I park outside and saw it. Now every time I call Kia and try to speak to a supervisor, I go straight to voicemail.

Bought my 2021 kia telluride sx with a cpo warranty with a little over 69,000 miles. at about 73,000 my car began to smoke and the dealership that I bought the vehicle from kept it for the day and sent me on my way with no diagnosis just simply stating they couldnt duplicate the issue and confirming they did NO testing on the vehicle. They stated that they topped the coolant and checked the oil in which my oil was in good level. 2 days later I checked the oil trying to figure out why my car was smoking and my dipstick had NO reading and no signs of oil. I topped the oil and immediately took the car to a different dealership where we began doing 1,000 mile testing on oil consumption and losing 1.5 quarts -- CPO warranty will NOT cover the issue because they stated it is A KIA WIDE ISSUE AND RECALL and even though I dont have specific recall they still refuse to cover. My car has been deemed as needing a motor replacement at 78,000 miles. Kia america DOES NOT stand behind their issues and refuse to help and they have denied the claims that have been made even after being escalated, they also refused to give a denial letter in writting or a reason why it was denied!

In December of 2025 at approximately 95,000 my 2021 Kia Telluride (VIN [XXX] ) showed the oil level was about two quarts low. My car has had regular maintenance including oil changes at Santa Fe Kia. At the next oil change appointment in March, I pointed out the oil consumption concern. At that point Kia recommended an oil consumption test be performed. The car had 96,700 miles at that point. At 97,700 Kia indicated that the oil level was fine. At 99,600 I checked the oil and discovered it was more than two quarts low. I called Santa Fe Kia to address the issue and they indicated that a quart every 1,000 miles is within Kia standards and recommended another oil consumption test which would take me over the 100,000 warranty. I called Kia customer care to address the issue. A case was opened, but they kept referring me back to the dealership to be dealt with. After researching the issue myself, I presented the well known and documented oil consumption issue amongst Kia consumers to include PCV valve and piston ring issues. I have an appointment scheduled for 4/16/26, but I am being told that I will be liable for the cost of the PCV valve replacement, compression test and oil leak test which are all known issues related to the problem. Santa Fe Kia's service manager is ignoring my request to submit an engine warranty claim citing that they didn't find a problem outside of Kia's acceptable oil consumption and Kia's customer care refuses to open a claim and keeps referring me back to the dealership. I will be at approximately 99,850 when I arrive at my appointment on 4/16/26. I am concerned that the engine has a major issue and will be told that my warranty is over by the time the issue can be determine and resolved. I am also concerned that there has already been engine damage done without noticing the high oil consumption.

Kia has 110,000 miles on it. We’ve regularly changed the oil at 3-5k mile intervals. A week ago, I heard loud knocking from the front of the car, along with loss of power. We drove it to our local Kia dealer (Kia of Bedford, OH), where upon inspection, they found cylinder bank 2 to be inoperative due to loss of oil. They found approx 2 quarts of oil in the engine - way below normal. They observed NO oil leaks. We inspected our garage and driveway floors, and there is no indication of any oil leaks. The Kia dealer said the engine needs to be replaced, at a cost of $12,700. I contacted Kia Customer Care, and they said it’s out of warranty and they won’t help. I replied back with an appeal to escalate to a higher / regional level for help. The oil had been changed at 105,000 miles. No oil leak present. Routine oil changes performed. This engine should never have had this issue at 110,000 miles. I know this is a known issue with this era of Kia engines. I’ve asked Kia to provide assistance in a repair.

Recently our 2021 Kia Telluride, had a fluttering/metal knocking/mechanical sound and I scheduled a shop visit at our trusted local mechanic. After their inspection, they found that the oil was extremely low and there was metal shavings in the oil filter housing. This was found when absolutely no warning lights were activated that would indicate low oil level or any other engine challenges. The vehicle is maintained with regular oil changes. The vehicle only has 65k miles. Looking further into this online, it seems very similar to the Theta engine recall from Kia. No warning lights/indicator lights, well maintained vehicle with regular oil changes, and to all of a sudden consume almost all the oil and have metal shavings in the oil filter housing is extremely concerning. As of 4/6/2026 the dealer is assessing the vehicle and coming up with a plan and or further actions to be done.

I am a 2nd owner of a kia telluride and the engine failed without warning at less than 90,000 miles. No check engine light, no temp gauge, no low oil level light. No warning at all. Just failure of the "push rod bearing" ny Kia was regularly maintained and when I took it to the dealership, they told me it was down about 3.5qts of oil! Again no low oil light? It holds 7qts...9,000$ later out of my pocket after being denied a goodwill engine replacement from kia to put a new motor in. I have found many others on on-line forums who have experienced this.
