2019 Kia Sorento Fuel system Problems

The vehicle involved is a 2019 Kia Sorento with approximately 111,000 miles. Over the course of ownership, the vehicle has experienced numerous unresolved mechanical and safety-related issues, including ongoing fuel leak concerns, excessive oil consumption/loss of oil, rough shifting, shift solenoid problems, rattling noises, shaking/vibration while driving, and repeated drivability issues. The primary safety concern at this time is a suspected fuel leak that multiple independent mechanics have identified. I have been told by at least three separate mechanics that the vehicle appears to have a fuel leak. During my most recent oil change at Valvoline, the technician expressed concern about the safety of driving the vehicle in this condition and warned me that driving a vehicle with a fuel leak could be dangerous. I previously brought the vehicle to Kia dealerships multiple times while the extended warranty was active and specifically requested inspection for the suspected fuel leak. On at least three separate visits, I was informed by the dealership that they could not find or confirm a leak. Because the issue was never resolved or properly diagnosed while under warranty, I am now out of warranty coverage and facing potentially dangerous and costly repairs. This issue has placed my safety and the safety of others at risk due to fear of possible fire hazards, stalling, or sudden vehicle failure while driving. Because of these concerns, I have significantly reduced driving the vehicle and currently do not feel safe operating it regularly. This has created substantial hardship because this is my only vehicle for work and daily life. Additional unresolved issues with the vehicle include: - Persistent rough shifting and shifting hesitation - Shift solenoid issues - Ongoing excessive oil consumption/loss of oil with no confirmed source - Constant rattling noises - Excessive vibration/shaking while driving - AC system failure around 60,000 miles - Electrical seat failur

2019 with 56,000 miles and the oil pressure sensor AND the fuel pump need replacing. Both items should be considered part of the powertrain but of course they’re not. Called corporate but got the “there is no recall” monologue from their representatives. Needless to say, I won’t make the same mistake with my next purchase.

My sorento started smelling like gas , inside & outside. Worse when I stop driving. The fuel pump pressure hose (that’s in a compartment under my backseat) is spraying fuel everywhere inside the compartment it in. The safety for myself and my grand sons that are all 2years old (3 of them) is we are inhaling the fumes from it separating steadily out under the seat their car seats are sitting on. I have not taken my vehicle to anyone but my friend after seeing a video of why a guys vehicle smelled like gas No inspection has been done by anyone I’m not even sure what steps I need to take or what to do now. There were NO messages, lights, etc., that flashed or popped up on my message center. It just all of a sudden one day started smelling like gasoline in my car.

. In October 2023 (see KIA service ticket) my KIA was brought into Jackson KIA Cocoa, FL, for something not operating correctly. The vehicle periodically would hesitate when pressing the accelerator and other times when you had pressed the accelerator to go faster and removed your foot from the accelerator, the vehicle would not slow down, rather continue to speed up even if you tapped the brakes. The service technician had the vehicle for two days and confirmed during several of his test drives that the vehicle would hesitate and speed up with your foot off the accelerator. The service technician said the fuel pump was the issue; however, to cover it under our vehicle warranty, the vehicle would need to generate either a service code error or the indicator light would have to turn on. Neither of these happened during the service technician’s test drives. The service technician wanting to confirm his assessment that the fuel pump was faulty, replaced the fuel pump with a new one and test drove the vehicle. The issues of hesitation and acceleration didn’t happen as they did with old fuel pump. The service technician put the old fuel pump back in because I refused to accept a charge for replacing the fuel pump when it was under warranty. I made an appointment with Jackson Kia in August 2024, explaining that the vehicle had not improved and no error codes and no indication lights but the vehicle was accelerating and hesitating even more than it was almost a year ago when their service technician confirmed the issue with the fuel pump. I left the vehicle with Jackson KIA again for three days for them to diagnose the problem and confirm that the fuel pump was faulty. The service technician confirmed that the other service technician from a year ago diagnosed the problem correctly. It was in fact the fuel pump and is exhibiting the conditions as outlined in the KIA Motors Fuel Pump notice, except the vehicle did not have any diagnostic error codes nor any lights

My engine was replaced and the fuel line was reported "mangled" by Kia of Coatesville where I took my car in after an engine replacement. One in which emissions codes were still going off. The car still smelled like fuel and it was then found that the fuel pump was leaking. To further this when we got the car back, the csr still smelled like fuel. The car was yet again taken in and found to have a crack in the fuel rail.

I have a 2019 Kia Sorento EX V6 with 65,000 miles. Recently started smelling fuel and had someone look at it. I was told there is a fuel leak above the left side of the tank in the evaporative line. No accidents. This should never happen on a vehicle for no reason.   NO system Failure. No malfunction. Yes, it is available upon request. NO inspections by insurance or police. No warning lights. Safety could potentially be at risk since fuel is exposed!!!!!

Bought car with 36k miles on it in July 2023. In Jan 2024, engine light came on and we noticed loss of power shifting between gears, had fuel injectors replaced/cleaned. In Feb 2024 at 51k miles, car made knocking noise, pulled over and shut car off, would not restart. Towed to KIA dealer, told the engine was seized and crankshaft snapped. I had regular oil changes every 5,000 miles as recommended by KIA. KIA dealer showed sludge in the bottom of the oil and accused me of adding oil after the engine failed -- false. KIA would not provide any remedy and is charging me $12,000 to replace engine. Seeing other complaints here for the same issue leads me to believe that this is a known issue for KIA on these engines but it has not yet reached critical mass.

There's something SERIOUSLY wrong with the Lambda Ii GDI engine similar to the theta ii. Like the SAME oil problems. I have a perfect service record at 89,600 miles and no accident and the oil light came on with solid oil, and even after the new oil, the new transmission flush and full injection service the oil light came on. They took it in numerous times and turned off the oil light and said nothing wrong but the ENGINE light went on once and I took it in 1 mile away and they cleared the light saying "no errors" and "no service problems they could see" and stated it might be the engine itself. It's acting JUST like the theta engine problems with kia sorentos. Like exactly the same. The blogs on the net are freaking out because a SLEW of people with 2019 sorentos were having the same problems. Not low on oil at ALL and the oil light keeps going off. They are helpless to fix it at Kia and said to trade in the car. There were six kia sorentos of the same make and in for repair recently and while I was in the lobby I was hearing customer ls call in complaining about oil lights going off. The blogs I'm reading have a slew of people this is happening to and I just read the California judges ruling and on the theta ii and I contacted the same lawfirm TODAY about the Lambda ii engine. I guess the feds are looking into it but it should be tied RIGHT away to the Lambda engines as well. There's something MAJOR wrong with the lambda.

KIA and HYUNDAI - all of their cars are unsafe. I have attached a letter to the NJ State Attorney General to explain some of the issues. These cars are absolutely unsafe and we have no peace of mind. They are killing us, literally. Please do all you can to immediately stop them. I cannot explain how upsetting this is. Please may you help our families. Our children drive these cars. Our brothers, sisters, aunts, uncles, neighbors, parents and all of us are in jeopardy of losing our lives. Thank you.

Kia America sent me a letter on June 30, 2023, which alerted owners of 2018-2019 Kia vehicles of a possible low-pressure fuel pump leak and explaining a warranty extension. I am distressed and disgruntled, frankly, by this strategy to wait until there is a fuel leak before repairing the problem. My wife and I are in our 70s and travel in the car often on overnight and even two-month trips. We now have to worry that we’ll start to smell fumes while far away from home. This is unacceptable. Why is Kia waiting until owners experience problems before fixing it? I asked our Kia dealer how much it would cost me out of pocket to get the fuel pump replaced now before we are stranded on the road. The dealer would not give an estimate. In addition, I wrote to Kia America and their Customer Care Center about this problem and after a month they have not responded. Finally, I called the Care Center hotline and waited for an hour and finally someone answered, but the connection was lost or the person hung up on me before I could even explain the problem.

4/5/2023 954PM-Neville Island bridge, Pittsburgh, PA While traveling on the interstate, the vehicle caught fire with no warning. We were heading out on vacation, so we had lots of things packed in the car. The fire started in the rear of the vehicle, and was extinguished by a passer by with a fire extinguisher, but re-ignited. it burned VERY fast. Unknown at this time what caused the fire. It is currently in the hands of my car insurance company, so it may be available for inspection. There were NO indications of a problem prior to large flames erupting form the read of the vehicle. In the car was myself, my two adult daughters and 6 year old grandson. He was seated in the 3rd row seat. One daughter in the second row, and myself and daughter up front. Once we realized we were on fire, we attempted to get the back doors open, but child locks were engaged. The key fob would NOT work, and my daughter and grandson were trapped in the burning car. we attempted to break the windows to get them out, but that was not successful. My daughter climbed back in the burning car and somehow got a back door open and they were able to get out and run. Within a few seconds, the windows blew and the flames shot even higher. We will NEVER EVER use child locks again. The problem had not been confirmed or reproduced to my knowledge. I believe my insurance company may be looking into it. I had to have a fuel system regulator and sensor replaced on this vehicle approx 1 month before this event. I had an oil change the day before. Police and fire department were present at the scene. There were NO warnings, lights, messages etc prior to eruption of flames. I have lots of photos, but have not been able to upload them to this site.

To whom it may concern: I am sending this email as an owner of a 2019 Kia Sorento for just 15 months, yet I am already experiencing significant mechanical issues. 3 weeks ago my car stopped accelerating while driving across a bridge, began shaking a making a weird noise once idle, and as expected my engine light came on. After calling endless Kia dealers I was able to get it towed 2 weeks later to my local Kia. To my surprise it was a high pressure fuel pump issue which seems to be a common issue amongst Kia Sorento’s. After only having this car for 15 months it should not be costing me $1,700 in repairs. I am requesting that this issue be looked into further and that Kia provides me with assistance.

The fuel system is faulty in that the cabin of my vehicle now smells like gas. The fumes gradually became stronger in smell. This is a huge safety concern in that it's impairing my way of driving. This put not just myself and my passengers but those on the road with me. Not to mention a fire hazard. I have gradually become I'll, major headaches, nasal/sinus pain, irritated throat and difficulty breathing, dizzy and nauseated. I'm on my way to 2nd ER visit in a span of 3weeks. Prior to smell I had notice a pull back in power. Feeling like the engine was lacking what it needed to run.
