The contact owns a 2025 Kia Telluride. The contact stated that while driving uphill at 55 MPH and depressing the accelerator pedal, the vehicle lost power. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The contact stated that the failure had occurred on several occasions. The approximate failure mileage was 22,000.

2025 Kia Telluride, rental vehicle, 29,450 miles at failure. Driving XXX W toward the [XXX] exit with my wife and two children (ages [XXX] and [XXX]), the cluster lit with simultaneous failures: electric power steering, electronic parking brake, ABS, stability control disabled, tire pressure monitoring, forward collision-avoidance, lane keeping, master warning. I photographed it. Nothing about how the vehicle drove had changed. At highway speed traveling straight, steering effort felt normal. There was no progressive degradation and no warning I could feel. I noticed a slight difference changing lanes for the exit. On the ramp itself, a banked turn taken at speed, the wheel required extreme force to turn. The loss of assist was undetectable until significant steering input was actually required, which happened mid-maneuver on an interstate ramp. I am a large, physically strong adult and forced the wheel through the turn. I do not believe a smaller, older, or weaker driver could have completed it, and a crash at that interchange seems a likely outcome for many drivers. Stopping on an interstate shoulder with two young children seemed more dangerous than continuing two miles to the airport exit, so I continued, with ABS and stability control also inoperative. The vehicle developed harsh, jerky shifting and audible clunking. In the rental return lot the wheel would not turn far enough to complete a tight turn. I shifted to reverse; the vehicle did not move, then shut down completely and would not restart. With the vehicle dead the front doors opened, but the rear doors and liftgate would not, and the windows were inoperable. My children were confined inside roughly 10-15 minutes at 86F until an employee climbed in from the front and released the rear doors from inside. The inability to open rear doors or the liftgate from outside after a total power loss is a serious defect in its own right.

System/Component Malfunction & Availability: The vehicle's electronic safety and engine control systems malfunctioned while driving at speed. This issue has occurred twice under identical thermal conditions, with the first instance occurring on 5/19/26. The vehicle is fully intact and available for inspection upon request. Safety Risk: During the first incident, a false dashboard warning triggered, but the physical engine remained running. However, during the most recent incident on 7/2/26, the defect escalated and the engine physically stalled while driving on the road in high 90-degree ambient temperatures. The stall caused an immediate loss of power and a complete loss of power steering assist, making the vehicle incredibly difficult to control and creating an imminent risk of a crash for my family and surrounding drivers. Dealer Confirmation & Inspection: Following the first incident, the vehicle was brought to a certified Kia dealership and left in their custody for 10 days for diagnostic troubleshooting. The service center stated they could not pull a hard diagnostic trouble code (DTC) and could not replicate the failure on a standard test drive. No other entities (police, insurance) have inspected the vehicle yet. Corporate Kia was notified (Case #26160914) but refused to authorize a specialized repair plan because the dealer could not replicate the issue. Warning Symptoms & Messages: There were no mechanical or performance warning symptoms prior to either failure. Both times, the issue began instantly with an audible cabin alarm and a prominent dashboard display message stating: "Engine Off! Shift to P or N, then start engine." During the first incident, the physical engine remained running despite the message, allowing us to safely pull over and reset the vehicle by cycling the ignition. During the second incident, under the same extreme outside heat (high 90s), the engine completely cut out mechanically, creating a severe stalling hazard.

While driving the car the engine lost all rpm, as in it went to zero rpms. The electrical system did not lose power. The console flashed a red warning light and had a message that I should shift to park or neutral, and restart the engine. You must apply the brake to restart the engine. When you shift to park/neutral and restart the engine, everything works fine. There was absolutely no warning that this was going to happen. No noises, no console warning lights, nothing. I believe it is a matter of time before this causes an accident. The engine just quits without warning. It has happened mostly at lower speeds while decelerating or braking, but has occurred once on a highway. Should this issue happen in high traffic, or high speed, it could absolutely cause an accident. The car has been at a dealership since 21MAY over this issue. They have driven it, but have not found anything wrong. They found no stored error codes. We have had a loaner vehicle since then. I'm fearful they will force us to take the car back.

Not sure if this is electrical or engine related.... The vehicle has experienced multiple instances (6 times) of unexpected engine shutdown while driving, including a recent event while turning off a major roadway. During these incidents, the vehicle loses power and displays the message: “Engine Off – Shift to P or N then start engine” This creates an immediate and dangerous situation, particularly when navigating traffic with passengers in the vehicle, including my grandchildren. Loss of engine power also impacts steering and braking assist, significantly increasing the risk of an accident. This condition is: Intermittent and difficult to reproduce I am aware that many other owners have reported similar issues, which raises additional concern about a broader defect.

I am reporting multiple life-threatening safety defects with my 2025 Kia Telluride. The vehicle has experienced Sudden Unintended Acceleration, where it accelerates to excessive speeds without driver input. During these episodes, the braking system fails to respond, only allowing the vehicle to stop once its internal safety systems intervene. Additionally, the vehicle suffers from unpredictable stalling and power loss; the engine frequently shuts off upon parking—followed by the electrical system cycling back on without the motor—and the vehicle consistently struggles to start in the morning. These recurring mechanical and electrical failures pose an immediate danger to myself and others on the road.
