2021 Kia Telluride Reliability Score & Common Problems

Owners of the 2021 Kia Telluride frequently report electrical system failures, with common issues including instrument cluster malfunctions, loss of power to door controls, and infotainment system failures. Symptoms often described include non-functional gauges, unresponsive door locks and windows, and infotainment screens that freeze or go blank. These problems are noted at varying mileages, with some occurring shortly after purchase and others emerging around 20,000 miles and persisting as mileage increases. Safety concerns are present, as some reports involve vehicles losing power while driving, resulting in loss of critical systems like power steering and collision warnings, and one incident resulted in a serious injury. Used car buyers should be aware of these potential issues, particularly regarding the electrical system's reliability and the associated safety implications.

Owners report two primary structural issues with the 2021 Kia Telluride: sunroof failures and windshield cracks. Complaints frequently mention sunroof components breaking, such as wind deflectors and track assemblies, leading to the sunroof becoming stuck in open positions, sometimes at speeds that could pose safety risks. Additionally, owners describe instances where the windshield cracks spontaneously, often while the vehicle is stationary or moving at low speeds, with some cracks expanding significantly over time. These issues typically arise within the first few thousand miles of ownership. Safety implications include potential road hazards from detached trim and sunroof glass shattering during driving, which could lead to loss of control or injury from flying debris.

Owners report several issues with the 2021 Kia Telluride's power train, primarily involving transmission and oil consumption problems. Complaints frequently mention transmission slipping, jerking, and hesitation during acceleration, often occurring at speeds below 50 mph and starting as early as 12 miles on the odometer. Additionally, multiple owners describe significant oil consumption, with some vehicles burning through several quarts in just 1,000 miles, leading to engine power loss and stalling without warning lights. Many of these issues arise around 30,000 to 50,000 miles, with some reports of sudden deceleration on highways posing safety risks. Potential buyers should be aware of these patterns, particularly if considering a vehicle with higher mileage.

Owners report frequent issues with the 2021 Kia Telluride's windshield and sunroof. Complaints commonly describe windshields that crack easily from minor impacts or spontaneously without apparent cause, with some cracks growing rapidly. Sunroof problems include spontaneous shattering and mechanical failures that prevent closing. These issues often occur at varying mileages, with some as low as 900 miles. Safety implications are notable, as shattering glass can distract drivers and potentially cause injuries, with one incident resulting in a minor injury from a falling sunroof component. Buyers should be aware of the potential for costly repairs and safety risks associated with these visibility-related failures.

Owners report recurring issues with the rear suspension of the 2021 Kia Telluride, particularly involving the self-leveling shocks. Complaints frequently mention premature shock failures, with symptoms such as clunking noises, leaking shocks, and a harsh, unstable ride that becomes difficult to control, especially on uneven terrain or when carrying passengers and cargo. These problems are often noted around 27,000 to 65,000 miles, with some owners experiencing multiple replacements within a short period. Safety implications include the potential for loss of vehicle control and increased risk of accidents due to the vehicle's unstable handling. Buyers should be aware of these reported issues when considering a used Telluride, particularly those with higher mileage or towing packages.

Owners of the 2021 Kia Telluride report issues with brake functionality, with some experiencing the brake pedal going to the floor without stopping the vehicle, leading to crashes in three instances. Complaints frequently mention complete brake loss, sometimes accompanied by dashboard warning lights, and issues often emerge shortly after brake work or software updates. In several cases, brake components like calipers are found to be improperly secured or become detached. These problems are reported at various mileages and can result in loss of vehicle control, posing significant safety risks. Potential buyers should be aware of these brake-related concerns, especially given the instances of crashes and loss of control.

Owners of the 2021 Kia Telluride report issues with airbag non-deployment during crashes. Complaints frequently mention that airbags fail to deploy in collisions involving significant impacts, including frontal and side collisions, even when vehicles are declared total losses. Reported incidents involve vehicles with mileage around 21,000 miles, though some complaints do not specify mileage. All reported cases involve crashes, with injuries ranging from facial and head injuries to back injuries. These reports suggest potential safety concerns for buyers considering this model, particularly regarding the airbag system's reliability in crash scenarios.
