Other Fuel System Problems of Kia Motor Sportage - part 1

While driving southbound on route 93 on 6/11/2026 during the morning commute, my 2021 kia Sportage suddenly sputtered and lost the ability to accelerate. I was traveling about 65 mph in heavy traffic when the vehicle abruptly lost power without any warning lights or prior symptoms. As my speed dropped, I had to cross multiple lanes to reach the breakdown lane, creating a dangerous situation for me and surrounding drivers. The vehicle had to be towed to a repair shop, where I was informed that the high?pressure fuel pump had failed and needed to be replaced. The car has only 22,000 miles on it and is just one month out of warranty. This sudden loss of drive power at highway speed poses a significant safety risk.

Oil was being diluted by fuel seeping in from the injectors and the high pressure fuel pump. Vehicle was brought in twice to fix the problem. During the 24-27 Feb 26 repair the high pressure fuel pump was diagnosed and replaced. On 16 Mar 26 I noticed the oil level had risen on the dip stick (after driving ~300 miles) about 5 mm and brought the car back to the kia dealer for diagnosis and repair. The high pressure fuel pump was diagnosed again as bad and replaced as were all four fuel injectors after they were also determined to be leaking fuel.

Car has 84000 miles on it for last 15-20 thousand miles there is a smell of gas in the oil. I took to dealership they charged me to replace a catalytic converter. Not even a year later the cars engine blew up. Now needs a whole new motor there is loud knocking and car will not accelerate.

I am reporting 2 safety related incidents with this vehicle. The first incident occured at 2,431 miles while driving on the highway. The vehicle suddenly lost propulsion/coasted with no throttle response and multiple warning lights/message appeared, including breaking/electronic parking brake/driver assistance-related warnings. This created a serious safety risk because if traffic had been behind me or moving faster, the sudden loss of power could have caused a rear-end collision or highway crash. The vehicle was taken to an authorized kia dealers on 3/9/26 and returned on 3/19/26 after wiring/connector related work. The second incident occurred at 4,658 miles when the panoramic sunroof glass suddenly shattered/exploded while driving. If the sunshade had been open, glass could have fallen directly on to the backseat passengers, causing injury, distraction, or loss of vehicle control. Broken glass could have affected nearby vehicles. The vehicle was taken again to the same dealer on 4/1/26 and remained there until 5/21/26. The sunroof was not repaired. Kia denied warranty assistance because outside influence/impact "could not be ruled out" despite the repair order report which states 'cannot identify a specific outside object or cause' and 'no damage was found clearly identifying an external object as the cause. ' I am concerend this may be a defect involving the panoramic sunroof glass and/or vehicle safety systems. The vehicle was out of service for about 60 total calendar days across both repair visits, including about 50 days for the unrepaired sunroof issue.

I was stopped in the left hand turn lane, then accelerated to cross 2 lanes of traffic. I then let off the accelerator, and applied the brakes to stop, and the brakes did not function. I then rear ended a vehicle in front of me due to the intermittent loss of brakes. It may have also been the propulsion system kept going. Either way the vehicle maintained the same speed of about 15mph until I collided with the vehicle in front of me which stopped me. The brakes worked fine again after the collision. There also was no forward collision avoidance system that was triggered in any way. This vehicle is a rental car.

My safety is put at risk. My car has stalled two different times on the highway. I was able to get it off the road after restarting the vehicle and coasting out. The engine was worked out by kia of mission viejo. They stated it was not due to rod bearing, although I was told on a separate occasion that there was metal in my oil in the same scenario then when they submitted the video to kia, they said they only saw the burnt valve my check engine light has went on a total of three times I’ve had the same exact work done three additional times as well as the knock sensor having to be replaced because it went off and burned out due to what happened on the highway. My car is part of the theta engine issue with kia.

I received a voluntary emissions update letter from kia, and although it was voluntary, the letter said failure to update could be considered lack of maintenance. The update was performed on xxx at dorsch Ford/kia in [xxx]. The vehicle ran poorly from that day forward. I gave it a couple of weeks to insure that the system could learn my driving habits. I then went to the dorsch service department to report my issues. The service writer {andy} said he hadn't heard of any issues with the update. I had him log in my issues to have a record that I complained. I returned several more times and talked to other service writers who told me that if they would check the vehicle and found nothing that I would have to pay service fees. The vehicle jerks and up/downshifts frequently and almost stalls sometimes when accelerating from a stoplight. It will lung periodically when navigating a parking lot at low speeds. It frequently searches for a different gear in traffic. To be clear, my car ran perfectly before this update. I asked them to put the previous tune back into the car but they said they can't do that. The car runs fine sometimes but the uncertainty of the jerking and shifting at improper times makes it dangerous to drive. Also almost stalling at an intersection is very dangerous too. I doubt that I am the only one to have this problem. Please help in any way you can to get this fixed without me having to spend money to correct a factory/dealer initiated problem thank you for all your help.

On December 24, 2025, while driving in traffic, my kia Sportage experienced severe lurching, bucking, and jerking, causing the engine to shut down. All dashboard warning lights illuminated, including a message prompting me to "turn engine back on. " the vehicle would not restart, necessitating a tow to horne kia. After several days of diagnostics, it was determined that a blown ignition fuse and a bad fuel pump relay were the issues, along with a battery replacement. However, just 19 days later, while attempting to merge onto the freeway, the vehicle again bucked violently, and the engine shut down with all warning lights flashing. The police had to assist in moving my vehicle out of traffic, and it was towed to courtesy kia in mesa, az. Once again, no error codes were found. After further diagnostics, it was discovered that the same ignition fuse had blown and that the catalytic converter had "shattered. " the catalytic converter was replaced. Upon picking up the vehicle from the dealership, and driving less then 5 miles on freeway, the vehicle was bucking and hard shifting once again resulting in a third tow to dealership just 48 hours later after the previous service. The dealership ran several diagnostics under kia's tech line, which revealed that the engine pistons are slipping and not functioning properly, resulting in loss of compression. Per kia's tech line, a new engine long block was ordered and replaced.

Shortly after purchase (9/20/25), I noticed that each trip showed much lower gas mileage than would be expected/reported via the vehicle sticker. Initially, these post-drive reports showed mileage around 17 mpg (city-equivalent). We noticed this quickly-- after the first few trips made. I calculated the mpg in early October & my calculations showed 16. 7 mpg. Over the next few weeks, similar mpg was calculated/showing. I reported this finding to kia st. Charles (point of purchase) early-to-mid October & was told to keep calculating mpg. I called again, indicating the problem continued &that we had a two occasions where we were unable to fill the car with gas-- a technician stated that the low mpg could be related to the long vehicle break-in period. We decided to take the car into the naperville kia dealership on 11/25 as this issue persisted. After nearly a week, we were ultimately told that without a check-engine warning, there wasn't much they could do to pinpoint or investigate. A check engine light then came on around 12/10 & we took the car back to naperville kia on 12/16 asking to look at the check-engine warning & continued gas mileage issues. We were told there was damage to the underside of the vehicle with the evap cannister split open & the under-shield smashed in. The technician, in the inspection video stated this would directly impact fuel economy. We were further told this was the result of damage to the vehicle caused by us, though we had not driven over anything, nor was there any other damage to underside, lower front of vehicle, etc. When I asked why gas mileage was impacted since the purchase in September & how this 'new' issue oddly happened to impact gas mileage, they had no answer. We were told this was outside of warranty & we'd be responsible for repairs. My concern is simple: there is a history of issues with the evap cannister with kias. And, the gas mileage issues was reported almost immediately. I feel the issue existed.

The vehicle is experiencing excessive engine oil consumption. The engine was found by the dealership to be low by 3 quarts of oil after about 1000 miles during an oil consumption test, indicating abnormal oil loss. The suspected failure involves internal engine components, possibly piston rings, allowing oil to enter the combustion chamber and burn. This condition creates a safety risk because the engine can become critically low on oil, without warning, potentially leading to engine damage, loss of power, or engine failure while driving. The problem has been reproduced and documented by the dealership during oil consumption testing. However, there are inconsistencies in the dealership’s reporting, as later documentation stated that no oil consumption was found despite earlier records showing excessive oil loss. This vehicle has been inspected multiple times by an authorized dealership and is currently part of an open case with the manufacture. The vehicle was also held at the dealership for approximately three weeks without clear documentation of work performed. There were minimal warnings indicators prior to the issue. The vehicle showed rough engine performance, which was consistent with oil fouling the spark plugs. No clear warning light reliably indicated the severity of the oil loss before the condition was discovered during testing.

While driving, the vehicle suddenly lost power and stalled. I was able to safely pull to the side of the road. The engine would not restart. Upon inspection, the engine was found to be completely out of oil despite being maintained according to recommended oil change intervals and not being overdue for service. There were no visible oil leaks under the vehicle and no prior low oil warning light or oil pressure warning light was observed before the failure. The vehicle had previously been serviced by a kia dealership for turbocharger-related concerns, including turbocharger boost control and wastegate actuator issues. The dealership later diagnosed the vehicle with a burnt valve in cylinder #1 and recommended complete engine replacement. I am concerned because this vehicle experienced excessive oil consumption without sufficient warning to prevent engine failure. The vehicle stalled while being driven, creating a potential safety hazard due to sudden loss of power in traffic. The vehicle is available for inspection. The failure has been confirmed by a kia dealership service department.

While driving my 2022 kia Sportage, the brakes suddenly stopped responding. I pressed the brake pedal hard several times and the vehicle did not slow down or stop at all. There was no braking pressure and no warning lights. Because the brakes failed completely, I crashed directly into a guardrail. The airbags deployed on impact. This was not driver error, it was a sudden and total brake system failure. The vehicle is currently in a wreck yard and requires immediate manufacturer inspection.

The catalytic converter in the kia. We were driving to texas to take my kids out for Mini vacation and it’s cut off right in the middle of the highway. My car was running just fine everything was fix properly. Can you check in the catalytic converter and see if it safely issue.

The brake peddle keeps jamming and sticking . The steering wheel is now very lose and a lot of play . There is a steering wheel with exclamation point flashing on the dash . When the card turns off it makes electrical noises . It is consuming oil . A pint a week . It’s been towed twice in three weeks.

My check engine light started blinking and the car was stalling out. I have now parked the car in my driveway. I bought the car October, 2024.

I have a hybrid and 4 times now since we've owned it I experienced a lag during the transition from electric to gas power when I am stopped and try to move again (example at a stop sign or traffic light), which followed by a sudden, lurching acceleration when the gas does finally kick in. It's almost caused me to hit a car infront of me once and side swipe a car that was passing as I was making a turn because I wasn't expecting it to do that the 1st time it happened. It doesn't do it consistently just randomly as I said its only happened to me 4 times and I'm the only one that drives the car and we've had it since July 2025 I believe and it has under 4000 miles on it at this point.

Defective fuel injectors on my 2023 kia Sportage I purchased 6 months ago.

I leased my 2020 kia Sportage lx in August 2019 and purchased the vehicle after the lease. In April 2025, the vehicle started emitting a strong gas smell after filling. Often, the pump would stop short around 8-10 gals instead of the usual 13-14 gals. I attributed both to perhaps cheap gas and faulty pumps. On September 23, 2025, I went to the dealership to check the gas odor and possible gas leakage and ticking engine noise. I ended up having to replace the entire fuel tank. The car is now 6 years old and, of course, out of its 5-year warranty. The report indicates that the leak was from the top of the tank and in the cabin; therefore, nothing was caused by normal wear or damage. Upon searching, I found that in January of 2019, previous years were recalled to replace the fuel tank due to similar issues (gas tank recall # sc172). Some of these models had recalls for the ksds as well, and my vehicle had been recalled and repaired. My concern is that this is my 3rd kia and 6th car total in life. Never have I had to replace a gas tank. I firmly believe some of these 2020 vehicles were built at the end of 2018 with the same parts in the 2019 recall; however were missed due to recall time and manufacturing rollouts.

In 2018 my I was driving home when it just shut off and wouldn’t start. Smelled like burning and had it towed to my house and had several mechanics look at it and couldn’t find the problem then as it was parked on day it started to smoke and the engine was burning I put out the fire and then a couple months later I got the recall information the car was a total loss and could t be repaired and no compemsation was sent to me. Ive contacted the class action suit and they were very vague with the information. I waited and the car eventually disappeared in which I thought the kia company picked it up. I still have t hear word from anyone and my car is no where to be found and I would like to be reimbursed for the car since it was paid off.

My truck consumes excessive engine oil.

My four month old kia Sportage suddenly lunged forward two times. Sudden acceleration incident. [xxx].

I have a 2025 kiasportage hybrid that I loved due to all its safety features. Yesterday I was pulling into a parking space when my car lunged forward two times making very loud sounds. I was near a brick pillar it it tore off the right front of my car. The bricks were damaged. When I came home I looked up kia Sportage lunching problems. There are many to read. They talk about “sudden acceleration’” and that is exactly what happened. It just lunged forward. Thankfully a human was not on the sidewalk. It went up over the curb and on the sidewalk. It’s called a jerking car in articles. Even if my car is fixable I won’t trust it. If this problem is fixable, why isn’t it fixed before selling the car to consumers. I’m quite distraught about this event. Warning must go out to consumers. I called a collision center this morning and they have seen this before. On the cars connect website, it tells of this event on 2020 kia Sportage. It says ‘’violent, scared the heck out of me. ” so, what is happening and why hasn’t it been fixed? I could have injured someone badly. [xxx] [xxx] arlington, texas information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car has the same issues as the kia soul and kia sorento. Kia has issued recalls for certain soul and sorento models due to various issues. A significant recall involves the 2020-2021 soul and 2021 seltos with 2. 0l nu mpi engines, where the piston oil rings may not have been properly heat-treated, potentially leading to engine damage and even fires. Additionally, some 2021-2022 sorento and 2021-2023 k5 models have been recalled due to a potential loss of drive power caused by a faulty transmission oil pump. I purchased my car within the same time frame between 2020 - 2021 as well. Many mechanics have also told me the fast oil burn issue has been happening to a lot of kia Sportages as well. I have also been told by kia dealership they have stopped selling my particular model for a while now as well. My engine is having issues, and the air in my car is also not working as well. Please help assist in this concern of mine and the issue that is very relevent and related to the kia soul and kia sorento. Thank you!.

My vehicle make and model has been documented to have had engine issues which has caused car fires from the engine compartment from what has been documented this is my best guess.

Vehicle: 2020 kia Sportage issue: excessive oil consumption — TSB #tsb_eng222 I am reporting a recurring issue involving excessive engine oil consumption in my 2020 kia Sportage. The engine is consuming oil at an abnormal rate between scheduled oil changes, requiring me to add approximately 2. 5 quarts of oil every month to maintain safe operating levels. This issue first began approximately 6 months ago and has been ongoing since. The affected component is the engine system, specifically related to abnormal oil consumption. The vehicle is available for inspection upon request. This issue poses a serious safety risk to me and my children. If the oil level drops too low, it can lead to sudden engine failure, loss of power while driving, or engine seizure. This creates a dangerous situation, especially when driving at highway speeds or in traffic, increasing the risk of an accident. The problem has been consistent and reproducible. It has been confirmed by an independent service center, which verified that the vehicle is consuming oil excessively beyond normal operating standards. I have brought attention to this issue through service evaluations, but no permanent repair has been provided to resolve the root cause. Prior to the issue, there were no clear warning signs. In some instances, the oil warning light only illuminates after oil levels have already dropped to a critically low level, limiting my ability to prevent potential engine damage or failure. This ongoing defect raises serious concerns about the safety, reliability, and longevity of the vehicle.

On Sunday, June 1, 2025, I was leaving work and was exiting i97 to enter on 695 and and I accelerated to proceed on 695 and my vehicle lost power, the engine light along with the oil indictor came on, and making a loud knocking sound. The vehicle was towed and taken to the mechanic and the code read, "knock sensor. " the knock sensor was replaced at $301. 85. I was able to drive the vehicle without any problems until Wednesday, June 3, 2025, when going to a doctor's appointment the vehicle's engine came on along with the oil indicator and the power was reduced and I had to pull over again with the same experience. The vehicle was again tested for codes and it then read camshaft sensor. This vehicle did not have any ill-performance, bells, dings, whistles or indicator lights until it was actually happening. According to the certified mechanic, this is a defect in the vehicle and although the part may be warranted, it will happen again and buyers will still have to pay for the part and labor, again, to have it fixed. I do not have my invoice on hand, however, I can get another copy.

While driving, the vehicle engine shut off while making a turn. Before the engine stalled, the engine began to sputter as I made the turn. I was stranded on the roadway as I could not restart the vehicle. For my safety, I stayed in the vehicle as there was no shoulder and many vehicles including dump trucks. Several attempts to restart the engine were unsuccessful - the engine would try to turn over and then stop. I contacted roadside assistance and the car was towed to the dealership. Diagnosed as a faulty fuel pump/bad connectors. Approximately 8950 miles. This is the second time the car stalled while driving.

The car continues to burn oil and have to put oil in it although not time for oil change. I took the vehicle to dealership several times because whenever I get gas it won’t let me start it right away or stutters after getting gas. Whenever the car is in park or idle it’s making a knocking noise and shaking really bad. The check engine light keeps going off and on but this most recent time it is not on. Initially I was advised they could only diagnose when check engine light on but that’s the issue because light does not stay on. I was on the freeway going about 70mph the car started declining in speed so had to hurry and pull over. Pulled over and turned off the car then it took several times to start back up. Vehicle currently at dealership waiting for more info but said it’s something related to the engine misfire.

I own a 2017 kia Sportage, and I recently experienced a malfunction indicator engine light turning on. Upon diagnosis by kia russ darrow at odana rd madison, WI , the vehicle displayed dtc p001000 – ‘a (intake)’ camshaft position actuator circuit (bank 1). They have noticed oil leakage around the e-cvvt motor plug area. It pointed to camshaft position sensor malfunction and kia service say what the vehicle needs is a cvvt cover and seals/gaskets relating to the variable valve timing on the camshaft as it’s throwing the camshaft sensor circuit “high” voltage kia has issued technical service bulletin (TSB) sa305, which acknowledges a similar problem in earlier production models of the same vehicle (built from December 10, 2015 – September 12, 2016). However, my vehicle was manufactured in January 2017, and kia has not yet included it in the affected range. Despite this, I am experiencing the exact same issue outlined in the TSB. This failure poses a potential safety risk because it can affect engine performance and reliability. If left unaddressed, it could lead to unexpected engine stalling, loss of power while driving, or further engine damage, creating a hazardous situation. I have not yet received confirmation from kia regarding an official recall or warranty extension for my vehicle, but the symptoms are identical to those covered under sa305. The issue has been reproduced and confirmed by a mechanic, and I am currently in the process of contacting kia for further inspection and assistance. There were no prior warning messages, aside from the check engine light (mil) illuminating when the problem first occurred. This complaint is being submitted to request an investigation into whether this defect extends beyond the current TSB range and to determine if additional 2017 Sportage models should be included in a service action or recall to prevent safety risks. The affected component is available for inspection upon request.
