2026 Kia Carnival Hybrid

Hello there - I am a fairly new owner of a KIA carnival hybrid 2026. I leased the vehicle in March'26. I have about 2200 miles put on the vehicle. On XXX at around 11am I was driving the vehicle on the left lane of freeway at ~65 mph and there was a sudden flash of Engine Maintenance service light and the vehicle cut out power to the accelerator pedal and started to bring the vehicle to a stop. This is in the fastest lane of the freeway while there was cars behind me. Luckily there was space to stop on the left side of the lane and I parked my car with the EMS light still on. Mind you that cars were going past me at 65+ mph. This is a major safety concern. I switched off the vehicle and turned it back on and the check engine light was still on but I was able to drive the vehicle to an exit and return home. I had the vehicle switched off for a few hours and when I turned it back on, the check engine light was gone. I scheduled a service at the dealership I purchased and explained the situation, they checked the codes/logs and test drove the vehicle and returned the vehicle back to me saying they cannot duplicate the issue. Whether the issue is resolved or not, I am majorly concerned that the diagnosis is incomplete and this issue can happen anytime on a freeway which is a safety hazard. This should not be happening on a brand new vehicle. I have raised a complaint to KIA corporate as well. There are a lot of other users companing similar issues: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving our 1 month old car we intermittently heard a loud clap sound, we assumed it was due to it being a hybrid vehicle. Well on Wednesday we were merging on to the freeway at approx 20 mph when we heard an extremely loud bang and the 3rd window imploded. There was nothing that hit the car, no point of origin for any foreign object, but rather an implosion. How was your safety or the safety of others put at risk? This happened within inches of my child's head and terrified my child. Has the problem been reproduced or confirmed by a dealer or independent service center? We immediately assessed the vehicle was not safe to drive and filed a complaint with Kia Corporate and called the dealership we purchased it from to be assessed and repaired. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It is currently at the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The only oddity was the intermittent clapping sound we heard randomly over the past few weeks of driving our new van.

We were driving on highway, approximately 2 miles from home, when we suddenly lost power to the drive train. Eventually it started moving again but after a short distance we again lost power to the drive train. It appeared that whenever it transferred from gasoline to hybrid or electric, we would loose power. We were in traffic and this was not a desirable situation. We applied hazard flashers and were able to limp home. We had no way to lock the hybrid into gasoline mode so every time it switch to electric we stalled out and had to wait several minutes before it would transfer back to gasoline mode. Vehicle is currently at dealership for repair but at this time they have not run any diagnosis on the vehicle.
