2025 Kia Telluride electrical problems

Filed Nov 4, 2026 · Electrical, Engine · CT

The brand new 2025 Kia Telluride I’m leasing has repeatedly stalled and immediately stopped without warning while driving. When this happens, you lose control of the vehicle, cannot steer and must shift into park. All while hoping no one slams into you and also keeping your fingers crossed that it starts again. This has happened at least 12 times from May 2026 to October 2026. The vehicle has been to the dealer for “repairs” three different times. However they have never been able to recreate the problem and therefore have not been able to fix it. I’m extremely worried that when this happens again it could result in an accident. I have contacted the manufacturer and dealership multiple times asking that they make this right. They have offered no options to replace or buy back the vehicle

The airbag warning light came on at about 4,000–4,500 miles in July 2026. The selling dealer found active code B142900 and a damaged yellow SRS connector under the driver-side second-row seat. The green wire is pulled out of the terminal, with exposed copper. The connector is hanging loose under the seat, in the path of the seat frame. The dealer wiring diagram identifies it as connector F49, Rear Side Airbag LH. The failed connector is still on the vehicle and available for inspection. Dealer case 26238900 was opened July 7, 2026 and closed July 8. Techline said it only handles engines, transmissions, and high-voltage batteries, and directed the warranty question to the service manager, DPSM, and warranty department. The dealer did not issue a written warranty decision, called the damage owner-caused, and quoted a main-harness replacement above $6,000. This is the same second-row driver-side side-airbag circuit recalled under SC262 / the federal safety agency 23V‑035 for harness damage from seat-frame contact during normal seat movement. The SRS light is still on at 6,182 miles, so that airbag will not deploy. A warranty review was submitted to Kia Customer Care Center on October 1, 2026. No crash, fire, or injury. Photos of the pulled wire, the under-seat location, and the F49 diagram are attached.

We purchased a new 2025 Kia Telluride 17 days ago. Just three days after purchasing the vehicle, I experienced a serious and potentially dangerous failure while driving in heavy traffic in downtown Chicago. The dashboard suddenly lit up, an alarm began sounding, and the following warning appeared: “Engine Off! Shift to P or N and then start engine.” I was forced to pull off the road in VERY congested downtown traffic, put the vehicle in park, turn it off, and restart it. I immediately contacted the dealership. The next day, I took the vehicle to the dealership for an unrelated detailing issue and asked them to check out the car to address what had happened. I was told it was likely a computer fluke and that I would need to wait to see if it happens again. The next day, the exact same thing happened while merging onto the interstate on a tight onramp in congested traffic. This time, I had significant difficulty getting safely to the side of the road and came extremely close to being struck by another vehicle. Again, I had to put the vehicle in park, turn it off, and restart it. The following day, I returned the Telluride to the dealership. It has been there for over a week. They seem to know this is a common issue with Tellurides but they've indicated that KIA has not provided guidance on addressing this specific issue. As a result, they could only respond to the code that was generated- which indicates an electrical control issue. I've contacted KIA and I'm waiting to hear if they can provide a fix that can guarantee I'm not put into another dangerous situation. If an older person or teenager had been in the situations I had been in, I can nearly guarantee there would've been a very serious and potentially fatal accident. Please help us address this issue!

When driving, the vehicle will randomly shut off. Every warning light and alarm goes off. A message displays on the dash to put the vehicle on P or N to turn it back on. This happens unexpectedly. It's happened about 16 times on the road and 2 times on the highway. This is a huge safety issue. We notified Kia in February of 2026, it's gone to the service department three times for this specific issue, but they are unable to recreate it and no codes are stored for them to see what it is. We have recorded the vehicle acting up once it's shut off. This is very dangerous that a new vehicle randomly shuts off, and no one knows what is causing it. Now, it's at the shop for the fourth time. This time the Kia engineers have asked the service shop to replace the engine harness along with some sensors and send it to them. We have recordings from Kia Corporate stating they dont know what it is. We even have a service tech stating that there are others with this issue but no solution has been uncovered.

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.

Twice I was making a right hand turn through a green light and an alarm sounded and the dash displayed an ”Engine Off” message. I was able to pull over and restart the car. I took it to the dealership but they were not able to replicate the incident. They told me that they tightened a few connections and sent me on my way. About three weeks later, I was driving straight at about 45mph and it shut off again. Fortunately I was again able to safely pull over and restart the car. This time I recorded it. I will return it to the dealership ASAP. I am afraid this will happen again while I am on the freeway or in heavy traffic and I won’t be as lucky as I have been.

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.
