2022 Kia Telluride

Our 2022 Telluride is binding when turning at low speed or accelerating on the highway we took it to our trusted mechanic, he believes it to be the all-wheel-drive coupling unit and that is a common failure point with these vehicles. I called our local Kia dealership and stated that the mechanic told me they need to check the firmware for the ECU to see if that may fix the issue. The dealership stated that they were just gonna have to replace the all-wheel-drive coupling unit instead of diagnosing the problem. After reading several reports from this government agency and other forms, etc. it sounds like the all-wheel-drive coupling unit is a common failure point and needs to be addressed as a recall by Kia.

The contact owns a 2022 Kia Telluride. The contact stated that while stopped on several occasions, the Auto START/STOP feature was activated, and the vehicle stalled. The vehicle was able to restart without any further issues. The vehicle was taken to a dealer on three separate occasions; however, the failure was not duplicated. The manufacturer was notified of the failure. The failure mileage was approximately 12,000.

The vehicle experiences a recurring mechanical failure where the electronic AWD coupling/rear axle locks up and binds when accelerating through turns. This creates an immediate safety hazard by altering steering dynamics and causing vehicle hesitation or severe wheel hop in intersection turns. A certified Kia dealership has already fully replaced the entire factory AWD Coupling assembly twice: first under the original warranty on July 16, 2024 at 48,054 miles, and again under warranty on May 2, 2025 at 59,350 miles. Following a preliminary check-in for the same symptom on April 9, 2025, this identical component failure has now recurred for a third time at approximately 77,000 miles.

The contact owns a 2022 Kia Telluride. The contact stated that while driving at an undisclosed speed at night, the side view mirror's blind-spot system generated phantom alerts while there was no object nearby. Additionally, the headlights inadvertently fluctuated between dim (low beam) and extremely bright (high beam) settings. The instrument cluster displayed that the vehicle unintendedly switched to Smart Drive Mode but failed to display the transmission gears. The trunk button intermittently failed to operate as needed. The back over prevention sensing system failed to alert that there was an object behind the vehicle while reversing. There were several unknown warning lights illuminated. The vehicle was towed to the dealer, who was unable to duplicate the failure, but twenty-six history trouble codes were retrieved, indicating the power steering, ABS, air bags, blind spot collision, front radar, and Integrated Charging Control Unit (ICCU) malfunctions. The contact stated that prior to the failure, a Voluntary Emissions Service Campaign: SC357 Engine Control Unit (ECU) was performed on the vehicle; however, the dealer informed the contact that the failure was not related. The dealer recalibrated the front radar, but the failure recurred at night while driving. The vehicle was towed back to the dealer, but the failure could not be duplicated. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 71,000.

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.

Catastrophic rear differential failure at highway speed following recent warranty repair. Vehicle previously brought to Kia dealership for rear differential knocking noise. Warranty repair performed and vehicle returned. Within one week, original noise returned with additional whirling/ grinding sound.While traveling approximately 70 mph on the highway, vehicle experienced a sudden loud bang and immediate abrupt stop in traffic. At the time of failure, wife and two children were in the vehicle. Incident posed a severe and life-threatening safety risk.Visual inspection indicates complete rear differential mechanical failure, with fluid and component debris present underneath vehicle. Vehicle is currently unsafe to operate.Failure occurred immediately following manufacturer-authorized warranty repair.

The oil filter housing cracked on the car, causing all the oil to leak out. In researching this, I have found that this is a common problem with the Kia Telluride and Kia Sorrento. The problem is that the oil filter housing is made of cheap plastic and not durable material such as aluminum or steel. This allows the oil filter housing to easily crack under stress. In speaking with the dealership, this is not an uncommon problem. I feel that this should be covered under the Powertrain warranty or through a recall. A quick Google search will show that the problem is widespread in the Sorrento and Telluride models. This repair cost me a total of $425. If I had not replaced or repaired oil filter housing, the engine would have locked up as all the oil at escaped onto the pavement.

The vehicle intermittently fails to shift gears and loses acceleration without warning, creating a serious safety hazard. The problem began in October 2024 when the check-engine light first appeared and has continued since. Despite multiple repair attempts by the Kia dealership—including replacement of the fuel pump, fuel pressure sensors, and ECU—the root cause remains undiagnosed, and the defect persists. When the vehicle was brought back in August 2025, the dealer’s latest recommendation on 9/30/25 was to replace the injector harnesses and front wire assembly, but they cannot guarantee this will resolve the issue.

Borescope inspection of the engine shows multiple signs of internal mechanical failure involving oil control, piston ring integrity, coolant intrusion, and cylinder wall damage. Excessive oil buildup is visible above the oil control ring, far beyond what is expected at 59k miles. Cylinder walls show heavy polishing where cross-hatching should be visible, indicating loss of lubrication and abnormal wear. Carbon deposits are extremely thick; in several areas carbon has flaked off and been pulled downward into the cylinder, creating scoring. Straight vertical scoring marks cut through the normal diagonal honing pattern, confirming blow-by and damage to the cylinder sleeves. Evidence of coolant intrusion is present, including orange discoloration consistent with rust/coolant contamination, excessive moisture, and steam-cleaned areas of the combustion chamber. The intake valve and combustion surfaces appear abnormally clean, consistent with coolant steam-washing. This suggests head-gasket failure, a block or head casting defect, or ring damage (possible cracked scraper ring). Coolant in the cylinders can wash away oil from the bore, leading to rusted pistons and accelerated scoring. Multiple pictures show severe scoring and loss of lubrication. This compromises the ability of new pistons or rings to seal, meaning the cylinder walls would continue to allow blow-by, oil burning, coolant intrusion, and friction. Even attempting to polish or recondition these bores would enlarge them, causing piston flutter, noise, and long-term failure. Based on the level of damage, the engine is no longer safe or reliable. A seized piston could cause sudden loss of power at highway speeds, creating a safety risk. The observed defects indicate a potential manufacturing or casting issue that may affect other engines. The dealership and KIA Consumer Affairs have been notified but there has been no replacement or resolution after 3 months of ongoing issues, and 8 weeks of holding my vehicle.
