Kia Telluride knocking problems

Filed Oct 27, 2026 · Transmission · LA

My car just started making a knocking sound when I turn. Brought it in for diagnoses and was told it's the AWD Coupler, WHICH is a part of the powertrain component, but it's not covered under my 100,000 powertrain warranty, and is only covered up to 60,000 miles. This is a known issue according to Facebook, blogs, and reddit and many Kia users have had the same problem on their cars. It should be a recall and fixed if it's happening so frequently.

On September 24th, 2026, while traveling with my family in my 2020, KIA, Telluride, the vehicle began experiencing an unusual engine vibration approximately 200 miles into our trip. About five miles later, I exited the freeway and stopped to inspect it. Once stopped, the engine began knocking loudly. I checked the engine oil and coolant levels; both appeared normal, and the temperature gauge was at its usual reading. After waiting about five minutes, I restarted the vehicle, but the knocking became worse with each start. I stopped running the engine and had the vehicle towed to a Kia service center. The vehicle had approximately 99,350 miles. The shop has described the engine problem as a “catastrophic failure.” The cause and specific failed components are cannot be identified in this kind of failure. This sudden failure during freeway travel with my family created a serious safety concern and I am sure this needs to notified so that it doesn't happen to anyone who own's the same car. There are particles of metal shavings found in Oil filter which concludes engine failure with no explanation. Only option I am given is get the engine swap which is ~70% of the total cost of the car. Kia support just says since the car is out of warranty they cannot do anything about it. This is a serious durability issue. I totally understand that the car warranty was reduced for the 2nd owner, but first user could also get this problem on the freeway and can be dangerous for everyone driving in the car as i am still under 100,000miles. I am trying to spread awareness, Kia already acknowledges that consuming 1qtz of oil every 1000 miles is normal, which means the engine has a issue that Hyundai/Kia needs to fix before more family starts facing this with even worse situation than ours. Please look into this so that they can acknowledge fix the problem and opens a recall for fixing it.

Purchased vehicle 8/31/2021 - 32k miles 10/18/21 - first mention of oil consumption (opened case with Kia) 2023,2025,2026. 3 more cases filed and DENIED with Kia customer care. Filed BBB claim, filed BBB anutoline claim, also hired lemon lawyer. Kia offered $6k to go away (I declined). *July 18,2026 Kia finally diagnosis and recommends engine replacement. Bore scope was used to discover scoring on cylinders from significant oil consumption. Vehicle is now smoking at take off (112k miles), current open case with Kia customer care again. Requesting buyback or settlement for the 3rd time in 5 years. Still paying $600 a month Safety concern: on a trip out of state vehicle dash lit up every icon and went dead in the middle of a packed 4 lane highway , started with power steering, no lights, no horn , couldn't roll window down.(video avail) Vehicle towed to dealership. Had replaced battery 2 times already. This has happened twice and my family was in the vehicle once on the large highway, very scary no one knew we were broke down bc we had no way to show it. People blowing and zooming by mad. Low oil light doesn't exist on this vehicle, I've been bone dry with no indication EVER. I now ride around with a 5 quart jug of oil and funnel in the back of my car since 72,000 miles. This should be illegal. Rear suspension: 4 times the rear suspension has been replaced (7 times in the shop to be fixed one time over 30 days) and has never been fixed , now making the same knocking noise it's always made. The car is a lemon and Kia knows it and will not stand behind their product. I DO NOT FEEL SAFE IN THIS VEHICLE, kia has been notified numerous times in every avenue and every way I could communicate, they say "we will call you with an update when we have one" that call NEVER happens.

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.

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.

Vehicle experienced catastrophic engine failure while traveling approximately 70 mph on a highway. I heard a loud popping noise and immediately lost power. The vehicle would no longer accelerate normally and I was forced to pull over. White smoke was visible from the engine compartment, and a large amount of engine oil leaked from the vehicle. This failure created a safety risk because it occurred at highway speed, resulting in sudden loss of power while traveling with surrounding traffic. The vehicle required towing and could not be driven from the scene. Prior to the failure, the vehicle had exhibited symptoms beginning around May 11, 2026. A check engine light illuminated and an independent mechanic diagnosed a cylinder 3 misfire and replaced the ignition coil. Following that repair, the check engine light returned. Additional symptoms included stalling at idle, knocking noises from the engine, and intermittent oil pressure warning lights. The vehicle was subsequently inspected by an independent mechanic who diagnosed a thrown connecting rod with damage to the engine block, including a hole in the engine near the transmission area. The mechanic advised that the engine requires replacement. The damaged engine is currently available for inspection. The vehicle has not been inspected by the manufacturer. No injuries or crash occurred, but the sudden engine failure and loss of power at highway speed created a significant safety concern.

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.

The vehicle began showing serious safety related symptoms before the engine failed. These included engine knocking, repeated sensor failures, the speedometer and odometer blacking out while driving, the navigation screen going dark, and the entire instrument cluster malfunctioning. These issues caused loss of speed information, loss of vehicle status, and loss of navigation visibility, creating unsafe driving conditions. Despite these warning signs, the engine later failed suddenly at around 71,399 miles with no warning lights, no oil pressure alerts, and no overheating indicators. The sudden loss of power created a highway safety hazard due to loss of propulsion and reduced steering and braking assist. The manufacturer and dealership also provided conflicting and misleading information about warranty coverage, including a claim of “no warranty on engine,” which contradicts the official warranty coverage documents. This has delayed proper repair of a safety related defect.

I had my most recent oil change on 2/20/26, and on 5/2/26 , the check engine light came on and I heard a knocking sound. I checked the dipstick and it was below the “low” mark. I hadn’t driven 3k miles yet!! I had to purchase 2 quarts of SAE 5w 30 oil to put into it. My vehicle is consuming more than 1 quart per 1000 miles.
