2017 Kia Sedona: sudden loss of power

Filed Mar 3, 2026 · Engine · GA

Vehicle Information: 2017 Kia Sedona VIN: [XXX] Engine: 3.3L GDI Mileage at failure: 186,000 miles Complaint: I am filing this complaint regarding sudden engine failure in my 2017 Kia Sedona equipped with the 3.3L GDI engine. The vehicle had approximately 186,000 miles at the time of failure and had just undergone a routine oil change prior to the incident. While driving on the highway, a warning light illuminated on the dashboard. Shortly after the warning light appeared, the engine began making a loud knocking sound. The knocking rapidly worsened, indicating internal engine damage. The failure occurred while the vehicle was in motion at highway speed, creating a serious safety risk due to potential loss of power and reduced ability to accelerate or maneuver safely. The vehicle was diagnosed as requiring a full engine replacement. The estimated cost provided was $5,758.05 for the engine, plus an additional $1,800 core charge, not including labor costs. This represents a substantial financial burden. It is my understanding that Kia has prior knowledge of widespread issues involving GDI engines, including premature internal bearing failure and engine seizure in multiple models. Despite this knowledge, the 2017 Kia Sedona with the 3.3L GDI engine has not been adequately addressed. Sudden engine failure at highway speeds poses a significant safety hazard and increases the risk of collision. I am requesting that the federal safety agency investigate the 3.3L GDI engine used in the 2017 Kia Sedona for potential manufacturing defects related to premature engine failure and internal component damage. Thanks, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2017 Kia Sedona has has regular oil changes about every 3000 miles. I was not due for an oil change quite yet and a ticking noise coming from the engine started to occur. I made an appointment at the Kia dealership right away. Just a few days before my appointment there was no warning light for the oil or engine until the engine failed, went limp and I lost power steering control, the brakes went stiff and all of the lights came on at once. It was very scary for me and my two children to lose that control of the vehicle. It can be inspected at Berlin City Kia where it currently sits and is in need of a replacement engine. After much research I have seen that this is a known issue for Kia engines and for some reason the 2017 Sedona is not included in any extended warranty's. Please investigate this. I did ask Kia for help in covering the replacement engine but was denied by the woman who I spoke to on the phone. I still put in a claim online anyway. It has been inspected by Berlin City Kia and they said there was "significant rod knocking". They are quoting me $9880 to replace the engine. After regular oil changes for the time that I have owned this vehicle and especially after I has the oil pressure sensor leak addressed as well over the last few years, it should not have died prematurely as it did. I am worried that the oil leaking so badly at that time may have pooled in the back of the engine which could have led to the rods wearing which in turn led to them knocking in the future. What else could cause this to happen? And so many other customers have complained about this exact issue. Please investigate this.

I own a 2017 Kia Sedona with approximately 120,000. It has the 3.3L V6 engine. While driving, the vehicle lost power and would not run. The lights and the dashboard would come on, but it would not turn over to start. I took it to a mechanic, and they confirmed that the engine had seized up and would have to be replaced costing $11,000. I then had it towed to the dealership that I purchased the vehicle. They also confirmed that the engine had seized up and would have to be replaced at a significant cost. I had no warning that anything was wrong with my vehicle as the check engine light did not come on. I did hear a slight knocking the day before this happened. My husband checked the oil and added a quart of oil, which was unusual since we had not seen any oil on our driveway. I did have a warranty, but it lapsed due to being over the mileage cap by 2,000 miles.

I will be driving and my headlight shut off. All of my warning lights come on, I lose all power and everything electrical shuts off. I am unable to use my blinkers, my head lights don't work, my radio doesn't work, and the car once put in park, won't shift. I have taken to 3 mechanics, spent over $800 and no one can figure it out. Kia won't help and claim I need to pay and take it to the dealership. They want $100 just to look at it. I fear for me and my children. This is a serious safety issue. I have seen several complaints online of the same thing. This is an issue with this vehicle and I'm scared I will die driving down the highway when my headlights just shut off

The van completely shuts down upon slowing down to come to a stop. This does not happen every time I stop, but has happen a total of 8-10 times in the 9 months that I have owned the van. Within the first week that I purchased the van the van stalled twice. When the van stalls there is a complete lost of power. In order to restart the van I need to return the key to the start position in the ignition and turn the key over again to start the vehicle. I have brought the van to the dealership where I bought the van on three occasions to have the vehicle diagnosed and repaired. They have yet to find a problem.
