2021 Kia Telluride: sudden loss of power

Filed Sep 21, 2026 · Engine, Transmission · OH

I purchased my 2021 Kia Telluride S new, with only 22 miles from the test drive. XXX (approx. 53,000 miles, vehicle age 18 months): The transmission failed while I was traveling approx. 75-80 mph on a major highway in [XXX]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. first through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. XXX: Due to parts delays, the vehicle was not returned until November 2022 after the transmission work. XXX (approx. four months later): The vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. XXX (exact date unknown): While opening the sunroof at a stop, a loud crack occurred and pieces of the sunroof track, plastic and metal, fell onto me and my passenger. The glass is intact but became partially stuck open without the track to guide it. XXX: The engine knock worsened and became a squeal while driving approx. 60 mph. The vehicle lost power, requiring me to turn on hazards and coast off to avoid accident. Dealership mechanic advised that the engine had thrown a rod and blown the oil filter housing gasket. The vehicle is currently at the dealership and available for inspection. Kia has denied coverage despite the failure of a component linked to excessive oil loss and a recently extended 180,000-mile warranty, even after the engine threw a rod following a sudden loss of oil pressure. The failed transmission has likely already been disposed of. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2021 Kia Telluride has developed progressively worsening engine problems without any warning lights ever appearing that may present a serious safety concern. Approximately two months ago, the vehicle began experiencing significant engine shaking and rocking. Maintenance and repairs were performed, and the symptoms temporarily improved. The engine symptoms later returned. The vehicle began making a noticeable ticking noise that progressively became much louder and occurred both while idling and during acceleration. The vehicle subsequently shut off after being driven to an independent mechanic. Multiple warning/diagnostic alerts appeared, and the vehicle would not remain running when restarted. The mechanic checked the engine oil and found it essentially empty. Approximately 4½ quarts of oil were added. The ticking noise continued despite the addition of oil. Later that same day, the engine developed a pronounced knocking noise that continued while driving. There was also a hot smell, and I had noticed discolored smoke coming from the exhaust. The vehicle is currently parked and is available for inspection. I have stopped driving it because I am concerned about an engine failure and the possibility of the vehicle shutting off or losing power while being operated. The vehicle has been maintained and I have documentation of its maintenance and repair history. The underlying cause of the severe oil loss and engine symptoms has not been determined.

the federal safety agency Vehicle Safety Complaint – 2021 Kia Telluride - VIN: [XXX] I am filing a safety complaint regarding my 2021 Kia Telluride. I purchased the vehicle on XXX, with approximately 124,000 miles. An oil and filter change was performed shortly before the sale. After about 2,000 miles/126K, the vehicle suddenly lost power and stopped. It was towed to a repair shop, where technicians found the engine oil level was extremely low or empty, despite no low-oil warning light appearing. The oil was serviced, and the vehicle was returned to operation. About 3,000/129K miles later, the vehicle again lost power and stopped in Ardmore TX. It was road side mobile mechanic found little to no oil and he refill the oil. After 100 miles/129.1K again same problem engine stopped and no oil. was towed to the same shop, where technicians found little to no oil and diagnosed severe engine damage requiring engine replacement. Mechanic informed there was no oil leak from the engine however, excessive oil burning in engine causing this issue. My concern is safety. On all three occasions, the vehicle lost power on the freeway at night while my family with two kids was in the vehicle. I believe excessive oil consumption and the lack of a warning before engine failure may represent a safety defect. I request that the federal safety agency investigate this issue and require Kia to review the vehicle’s engine design and warning systems.

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 the federal safety agency 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.

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.

The 3.8L Lambda II GDI V6 engine suffered catastrophic failure at approximately 102,000 miles. The root cause is excessive oil consumption documented by an independent repair shop well before the 100,000-mile powertrain warranty expired. At 81,207 miles, during a routine oil change, the mechanic checked oil level before draining and found nothing on the dipstick. Only about 3 quarts drained from an engine with 6.9-quart capacity, meaning nearly 4 quarts were consumed since the last change. This finding repeated at 88,408 miles, with the shop documenting it was the second time oil was critically low. Both events occurred within the powertrain warranty. Original invoices are available for inspection. At no point during ownership did the vehicle display any warning — no low oil level indicator, no low oil pressure warning, no check engine light — despite oil levels falling dangerously low on multiple documented occasions. The absence of any driver alert while the engine operated with less than half its required oil is a serious safety deficiency. The engine failed on while driving with passengers including three young children, causing complete loss of power and requiring an emergency pullover. Loss of engine power at speed creates serious crash risk. The vehicle was serviced at an authorized Kia dealer at 60,449 miles where a 60K service, multi-point inspection, and recall SC243B were performed. The dealer made no mention of oil consumption, did not reference TSB ENG222 (addressing excessive consumption across multiple Kia engine families), and did not perform an oil consumption test. Kia Consumer Affairs refused to submit a goodwill claim and closed the case, citing incomplete oil change documentation — despite the defect being documented within warranty. Excessive oil consumption in 2020-2021 Tellurides appears systemic based on numerous owner reports describing the identical pattern: extreme consumption, no dashboard warnings, and eventual engine failure.

2021 Kia Telluride experienced sudden engine failure at approximately 120,000 miles. The failure occurred without any prior warning. There were no oil warning lights, dashboard alerts, or other indicators of low oil or engine malfunction before the engine failed. After inspection, the mechanic found no oil on the dipstick and discovered metal flakes in the engine and oil filter, indicating severe internal engine damage. No external oil leaks were identified that would explain the loss of oil. This suggests a potential internal engine defect or abnormal oil consumption without warning to the driver. The vehicle has been regularly serviced and properly maintained according to recommended maintenance schedules. There was no neglect, missed oil changes, or failure to maintain the vehicle. This sudden and unexpected engine failure creates a serious safety concern. A loss of engine power while driving, especially at highway speeds or in traffic, could significantly increase the risk of a crash and place the driver, passengers, and other motorists at risk.

Component/System Failure: The engine and lubrication system appear to be malfunctioning. The vehicle has repeatedly experienced sudden engine shutdown while stopped at traffic lights and during low-speed operation. The dealership has identified oil leakage involving the oil pan and oil filter housing and has indicated there may be an internal oil leak within the engine. The vehicle is available for inspection upon request. Safety Risk: When the engine shuts off unexpectedly, the vehicle loses propulsion in active traffic. This creates a risk of rear-end collision and prevents immediate maneuvering out of traffic flow. The loss of engine power while stopped or moving at low speeds presents a serious safety hazard to myself and surrounding drivers. I am concerned that the suspected internal oil issue may lead to catastrophic engine failure while driving. Dealer Confirmation / Reproduction: The issue has been reported to the dealership multiple times beginning in January 2025. The vehicle has undergone multiple inspections and repair attempts, including partial fuel injector replacement, battery replacement, and an oil consumption test. The dealership has acknowledged oil leakage and has stated that replacing the oil pan gasket and oil filter housing may not resolve the suspected internal oil leak. The defect has not been permanently corrected. Inspection by Manufacturer or Others: The vehicle has been inspected multiple times by the dealership. The matter has been escalated to Kia Corporate for review. No police or insurance inspections have occurred, as no collision has yet resulted from the stalling events. Warning Lamps / Symptoms: During each stall event, the check engine light illuminates along with multiple dashboard warning lights. The stalling first began in January 2025. Oil-related concerns and possible oil loss were reported during prior service visits. The condition continues despite repair attempts.

On 11/01/2025, while traveling on the highway traveling at a speed of 80mph, my vehicle suddenly would not accelerate beyond 60 mph. I managed to exit safely, but this created a dangerous situation for both me, my daughter and other motorists . The next day, Firestone inspected the vehicle and informed me the engine contained zero oil—yet no oil light, check-engine light, temperature warning, or sensor alerts were triggered at any point. There were no visible oil leaks, suggesting internal oil consumption, which I had reported to Kia in October of 2024. On 10/21/2024, I paid $3,300 for a flywheel/ignition repair at a Kia dealership. When I dropped off the vehicle for that repair, I specifically reported abnormal oil consumption and requested it be checked. Kia did not diagnose or remedy the concern. The combination of: -Complete oil loss -No warning indicators -Sudden loss of power and inability to accelerate -Occurring at highway speed constitutes a critical safety defect. Drivers cannot take preventative action if the vehicle provides no indication of catastrophic engine failure until it is already occurring. This defect exposes drivers, passengers, and surrounding motorists to severe risk of collision or injury. Additionally, the dealership later provided a Carfax entry simple stating "car maintenance" on 10/22/2024. No record of what was repaired, indicating inaccurate or incomplete documentation. I am requesting that the federal safety agency: -Review this incident as a potential engine safety defect. -investigate whether other 2021 Kia Telluride owners are experiencing similar catastrophic oil -loss or lack of warning indicators. -Assess whether current recalls adequately address this failure pattern. -Determine whether an additional recall or investigation is warranted.

We own a 2021 Kia Telluride which we bought new, have changed the oil as expected and had the 100,000 mile check completed. It now has about 116,000 miles and has been a great and safe car, until now. On a random trip home, traveling on a busy highway, we had to pull over because we suddenly lost power. Our children were in the car and this was very dangerous on a very busy highway. We had it towed to our local garage and was told it was down 3-4 quarts of oil which wrecked the engine and we would need a new one! There were no warning lights for the engine or the oil at all. We are currently having the engine replaced at our very hefty expense as we have no other choice. I see this is quickly becoming an issue with the 21 Telluride and I hope that Kia will do something about it!

I am reporting a serious and ongoing electrical and transmission issue with my 2021 Kia Telluride (VIN: [XXX] ). The problem began under 20,000 miles and has continued intermittently for years, progressively worsening. My vehicle is currently at ~99,600 miles and under extended warranty. The key safety concerns include: Transmission Lockout: The vehicle intermittently becomes stuck in Park and will not shift, even with the brake depressed. No-Start Condition: The vehicle will randomly become completely unresponsive—no dash lights, no infotainment, and no engine start. Electrical System Failure While Driving: Multiple safety systems fail mid-drive, including: Loss of power steering and air conditioning Random activation of ESC, TPMS, Collision Assist, Blind Spot, and Parking Brake warnings Infotainment screen turns off while in motion Component Failures Due to Electrical Shorts: Both the radio and the backup camera were diagnosed with shorts and had to be replaced under warranty. Brake Lockout Post-Shutdown: The brake pedal becomes very firm and the vehicle will not restart until hours later. Most concerning, my wife and children have been left stranded in the disabled vehicle on multiple occasions due to these issues. The car has been in the shop several times — around 50,000 and 80,000 miles — but no permanent resolution has been found. This is a clear and escalating safety hazard. The failures affect critical systems while driving and leave the vehicle unpredictably disabled. Kia has been made aware and an escalation is underway, but I am filing this report to ensure the federal safety agency is aware of the pattern and potential danger these failures pose to others.

On [XXX] my vehicle had a collision warning signal, then tire pressure, then brake lights and entire dash instrument panel. I parked the vehicle, then later in the evening test drove it again and the panel lit up again, in addition to the loss of the speedometer, tachometer, gear display, and drive mode display, so I immediately drove it to Courtesy Kia in Altoona, PA. On 4/18/25 Wendy Giordano of Courtesy Kia confirmed vehicle intake Courtesy Kia reset codes and was unable to replicate or diagnose a repair. The vehicle was returned on 4/23/25 despite my expressed concerns over safety. On [XXX] the vehicle again displayed the collision warning and the instrument panel lit up again, in addition to the loss of the speedometer, tachometer, gear display, and drive mode display. I got off the highway and limped the vehicle closer to my home, stopped for a brief time, and proceeded the three miles to the dealership. In this time I lost power steering, and eventually brake lights and turn signals within 1,000 feet of the dealership and was nearly collided with in front of the dealershipOn 5/12 I continued to ask status and request a loaner with no adequate follow up. I was bounced between JT, Tyler and Wendy Giordano my service advisor. Around 5/22 I called in requesting an update and was put on the phone with the service tech to describe my issues On 6/6/25 John from courtesy ford left a 2 minute long rambling voicemail, 6/3 he said he received a fax. He said he spoke to service department and I could drive the car, that I could be driving the car now. "he wasn't sure what was going on with it" They've driven it and can't find anything. Kia is looking at video, service rep there on Tuesday and find nothing wrong. I think, how long and haven't had it long. Suggest you "just drive it, I don't know" In addition I've followed up with numerous emails and calls to determine course of action and repair and haven't had a productive repair plan.
