While driving approximately 70 mph on the highway returning from Door County, 20 miles north of Manitowoc, on a clear day with temperatures in the mid-to-upper 70s and no other vehicles nearby, the panoramic sunroof glass spontaneously shattered with a loud noise. The middle portion of the glass was sucked outward/up and away from the vehicle. The sunroof had not been used (or we are unsure if it was ever opened more than once or twice since acquiring the vehicle). Immediately afterward we heard significantly increased wind noise. We pulled over, went to a car wash, vacuumed all small glass pieces from the vehicle, and duct-taped around the inside seam to prevent any remaining shards from entering the cabin. The vehicle is only a few months old. No impact, debris, or external object was involved. Photos of the damaged roof and remaining frame have been uploaded.

The contact owns a 2027 Hyundai Palisade. The contact stated that while initiating vehicle operation, the messages "Check Hybrid System" and "Stop Vehicle and Check Power Supply" was displayed. The failure was a recurring failure. The dealer was contacted and received the same messages. The dealer stated that the failure was associated with the 12-Volt battery in the vehicle that was low due to being in port for a while; however, the failure persisted. The dealer was contacted and stated that the corporate office was working on the remedy, but there was no estimated date when the remedy would become available. The manufacturer was not made aware of the failure. The failure mileage was approximately 100.

Car will not start after being parked in my garage for 24 to 48 hours. The battery is drained and needs to be jumped. This has happened three times. I am sure that no fob is left in the car, no interior lights are on, no door is ajar, and nothing is plugged into any USB ports.

Detailed information is in the attached pdf file, but in a nutshell, Kia is covering a safety defect in their vehicles by claiming the process is “proprietary”. On several occasions we have lost propulsion, which means we had no control over our vehicle, and Kia’s explanation is simply, “the vehicle is performing as intended “! These incidents always happened at low speeds, just accelerating from a stop, but left us in a precarious situation as we were left in the middle of a busy intersection with no control over our vehicle! Propulsion would eventually return. After surviving several of these failures, I learned the proper thing was to let both pedals return to their idle position and then the vehicle would recover. This is a most difficult thing to accomplish when surrounded by angry drivers! The failures were identified by Google AI as a Brake Override System, also known as Brake Throttle Override. However, Kia already has a very functional Brake Over Accelerator process, so why would they have two similar functions? Kia knows the answer but is refusing to divulge any information regarding the intention or purpose of this mysterious process which makes our vehicle unsafe!

I am writing to formally express my serious concern and disappointment regarding my Kia Carnival Hybrid. Shortly after purchasing the vehicle, with only approximately 6,000 miles on the odometer, the vehicle suddenly stopped operating while I was driving on the freeway. This created a dangerous situation for my family and other motorists. The vehicle had to be towed to an authorized Kia dealership for diagnosis and repair. No warning or message had appeared before the issue. The dealership retained the vehicle for approximately one week and informed us that a PCB (Printed Circuit Board) component had failed and needed to be replaced. After the repair was completed, we were assured that the issue had been resolved and that the vehicle was safe to drive. Unfortunately, after driving only about 50 additional miles, the exact same issue occurred again. The vehicle once again became inoperable, leaving us stranded and raising significant concerns about the reliability, safety, and quality of this vehicle. We towed the vehicle on 6/22/26 and Kia dealership had it till today 8/7/26 and corporate keep saying they working on it but unresponsive.

The floor railings above the battery, that allow the second row seats to slide, get hot. Extremely hot to the touch. Burning my children’s feet. Not sure if it’s related but the a/c does not stay cold when driving long distance and the HV battery just died last month for no reason. Brand new car.

While driving on an interstate during a heavy summer thunderstorm, the vehicle suddenly displayed a warning stating, "There may be a problem with the Battery Management System," along with a "Check Hybrid System" message. At the same time, the check engine light illuminated and the hybrid system stopped functioning without any prior warning. Approximately 10–15 minutes before the incident, I had driven through approximately 4 inches of standing water on a surface street at a speed of about 25 mph. After entering the interstate and traveling at approximately 65 mph in heavy rain, the hybrid system suddenly disabled itself. Cruise control was not engaged at any point during the trip. Immediately after the warning appeared, the vehicle experienced a significant loss of power and entered what appeared to be a reduced-power (limp) mode. The gasoline engine continued to run, but acceleration was severely limited, making it difficult to maintain speed or accelerate with surrounding highway traffic. This occurred at night, during heavy rain, on a busy interstate.The unexpected reduction in power created a hazardous situation and increased the risk of being struck by other vehicles while attempting to merge or pull over. After I was able to safely stop and restart the vehicle, the "Check Hybrid System" and Battery Management System warning messages disappeared. The vehicle has approximately 6,000 miles and was purchased new. This vehicle is used to transport my family, including my wi

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 PURS

I own a 2026 Carnival Prestige SX Hybrid and having loss of propulsion problems. After much research, and absolutely no help from KIA, I now think my problem is my foot, size 15, is too large to safely drive this vehicle. My shoe intermittently depresses the brake ever so slightly while I accelerate from a stop. This triggers the Brake-Throttle Override which temporarily cuts propulsion power. The BTO is in all US cars but of the five vehicles (2025-26, different manufacturers) I have driven this past six months, this is the only one that has given me concern for my safety! KIA claims the vehicle is operating as expected! I claim that they have engineered the brake and acceleration pedals too close to each other creating a serious safety issue for those of us with larger foot sizes. The owners manual makes no mention of the BTO function nor how to restore propulsion once the BTO has been activated! While all US vehicles have the BTO function, they vary as to how the function performs. In KIA, once the BTO is triggered, all propulsion is suspended! The BTO was designed to prevent runaway acceleration. In this KIA, they have created a new safety problem because they failed to allow enough space for larger footed individuals room to safely operate their vehicle! KIA needs to introduce a foot size requirement for all prospective buyers or redesign the area around the accelerator and brake pedal so safety is no longer an issue!

What component or system failed: The hybrid battery management system (BMS) failed while driving. The dashboard displayed a Battery Management System error along with a lane assist warning. The vehicle then completely lost propulsion, no response from the accelerator pedal, while on an incline, causing the vehicle to roll backward down the hill. The vehicle is currently at the dealership (Kia Temecula) and available for inspection but no one has reached out to me for days. Safety risk: The vehicle lost all forward propulsion while in motion on a hill and began rolling backward, with no ability to accelerate or control forward movement. This posed a serious risk of collision or rollaway accident. I shut the vehicle off and restarted it, which restored partial function for approximately 1 minute before the same failure recurred. Has the problem been reproduced/confirmed: Not yet confirmed by dealer — vehicle was towed to Kia Temecula on 7/12/26 via Kia roadside assistance and is awaiting diagnostic inspection. Dealer scheduling offered August 4, 2026 as the earliest availability, which is unacceptable given the safety nature of the defect. Inspected by manufacturer, police, insurance, etc.: Not yet inspected. Vehicle towed to authorized Kia dealer; diagnostic pending. Warning lamps/messages prior to failure: Yes — Battery Management System error and lane assist function warning appeared on the dash immediately before the vehicle lost propulsion. No prior symptoms were noted bef

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.

2026 Kia Carnival Hybrid – Purchased 9/5/2025 Mileage: 8,450 April 2026- While driving over 60 mph, the vehicle's acceleration failed. A "Hybrid Failure" warning appeared on the dashboard, and the vehicle quickly decelerated. I had seconds to safely cross 3 lanes, and the vehicle had to be towed. The vehicle was at the dealership for 13 days, during which no problem codes were reported, and diagnostic scans appeared normal. No safety feature or diagnostic system reported this failure! I was told to take the vehicle because they had nothing to fix without a diagnostic report. May 2026- I drove the vehicle for a few weeks before this occurred again, with the same warning and complete deceleration. The vehicle was brought to a 2nd dealership, nearest to this incident. They have had the vehicle for 29 days with no safety or diagnostic issues to report and no ability to duplicate the problem. During this occurrence, my daughter was able to video the dashboard and deceleration from the passenger seat. I have provided this video to KIA. The national KIA team is refusing a buy-out option for this vehicle after my family and I have repeatedly been put in danger on the road. It also puts drivers around us in danger as we frantically attempt to proceed to safety while quickly decelerating. It is also extremely alarming that the safety systems and diagnostics do not show that these problems are occurring. While the local dealership has been understanding and professional to date; however

I am reporting an intermittent but serious safety issue with my Kia Carnival involving the backup camera system. Since approximately May 2026, the rear backup camera has failed more than 10 times. When the issue occurs, the display will either: Show a completely blank screen, Flicker repeatedly, or Turn into a solid green screen. Once the failure begins, it continues even after repeatedly turning the vehicle off and back on. The system only starts working again after the vehicle has remained powered off for several hours. This is a significant safety hazard because when the backup camera fails, the parking assist system/sensors also stop functioning. As a result, while reversing, I lose both the camera view and the audible/object detection assistance. This substantially increases the risk of backing into a pedestrian, child, cyclist, or another vehicle, especially in parking lots and residential areas. The problem has occurred more than 10 times over the past several weeks. I have taken multiple videos clearly documenting the failures, including the blank screen, flickering display, and green screen. I have brought the vehicle to the Kia dealership for inspection. However, because the problem is intermittent and could not be reproduced during their inspection, they stated that they were unable to diagnose or repair the issue. Despite this, I have video evidence demonstrating the recurring failure. This appears to be an intermittent electronic or software defect affecting a cr

I had pickup my vehicle from the dealership where it had been since the 29th of May due to a previous incident exactly the same as what occurred this time. The vehicle had been returned to me as the service department could find nothing wrong from the May 29th incident. On my way home from the dealership, the vehicle started the same as on May 29th. When accelerating from a stoplight, I lost all propulsion. After about 60 seconds the vehicle recovered and I turned to go back to the dealership. At the aforementioned intersection (crossing over I35) it again lost propulsion, only this time for a longer period of time. I was in heavy traffic and the car behind me was honking even though I had my hazard warning flashers operating! I made it to the dealership where the service manager agreed to do a ride along. We were about to the end of the ride along when the vehicle lost propulsion power. It wasn’t as severe and recovered quickly. The service manager said he had noticed the brake pedal move at the time I accelerated. His theory was that the brake being applied at the same time as the acceleration cause the computer to get confused and it’s reaction was to remove propulsion. No offer was given to take the vehicle back for further testing. I dropped the service manager off and proceeded to return home, being cognizant of my foot placement and insuring it was well away from the brake when accelerating. KIA Care has so far refused to get involved. While I recognize braking at the

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.

While driving a brand new Kia Carnival Hybrid (purchased yesterday), I experienced a severe, life-threatening powertrain acceleration lag from a rolling start. My children were in the car and this was very scary. When attempting to accelerate into oncoming traffic on a wet road surface, the vehicle completely hesitated and dropped power for approximately 1.5 to 2 seconds, leaving the vehicle stranded in the path of oncoming traffic. When the power finally engaged, it delivered a violent surge of torque that caused the front tires to break traction and squeal aggressively. This software-driven hesitation and power-distribution lag represents a severe safety hazard.

-A "Check Hybrid system. Stop safely. " warning has come on 7 times now. The vehicle loses power and slows down abruptly before coming to a complete halt. This has happened on railroad tracks, the highway, and an intersection where my wife and children were almost hit by other motorists. The dealer has not been able to reproduce the code, but we have pictures and videos of said incidents. The vehicle has been inspected by Kia technicians and "fixed" multiple times, but this keeps happening and I will not risk my family's lives any longer. There has been zero warning every time this system failure has occurred. We are undergoing a buyback process with Kia corporate and are prepared to take legal action under Georgia state lemon laws. Thank you for your time.

Driving on freeway with the heater on, Cold weather, car had multiple issue messages (transmission control unit and adaptive cruise control) as well as a check engine light come on as the car went limp and would not accelerate. Has to pull off of the freeway after nearly getting in multiple accidents due to losing speed from 65 mph to 30. Had the gas pedal all the way to the ground and the car would barely accelerate.

Without presenting any errors, the vehicle appears to enter some sort of limp home mode which limits speed to 31mph until the vehicle is turned off and re-started. 31mph is well below the speed limit on most public roads and being limited to this speed with no ability to pull over to stop/start the car creates a significant safety hazard to the driver of the vehicle and other motorists.
