2017 Kia Sportage acceleration problems

Filed Sep 25, 2026 · Acceleration, Engine · TX

While traveling at highway speeds on the freeway, the engine experienced a sudden, catastrophic failure, causing the vehicle to lose power and violently force itself into an emergency low-speed "limp mode." This created an immediate, severe collision hazard with surrounding high-speed traffic. The vehicle is a 2017 Kia Sportage with a 2.4L Theta II engine, which had previously received the mandated KSDS safety software flash. The authorized dealership (Southwest Kia) refused to honor the safety recall and lifetime warranty parameters for this engine failure, instead classifying the issue as a "burnt valve" to deny coverage and forcing an out-of-pocket retail customer charge of $6,864.49 for a full engine assembly replacement.

One day as I was turning at a green light the car completely stopped on me. I had to turn it off and then restart it and it worked fine. About a week later I had to drive to my cousin's house 45 minutes away and the car would not go, it acted like it was stalling and It didn't want to go over 2000RPMs and it was really sluggish like it didn't want to shift into the next gear. I finally got on the highway and it would not go past 60 miles an hour and then also if you try to drive it, it will slow down like its shutting off on you. I've had a new battery replaced, 4 new tires a windshield, and wipers replaced. I took the car to AutoZone and also to another guy and both of them used their computers and said that it's the engine and they called it rod knocking. I called customer service and they said yes their is a recall and that they would replace the engine. I tried to call kia in mesquite Texas because that is the closest one to me and I left a voicemail they did not call me back I am carless I'm a single disabled mother I need a working car.

While driving on the interstate at highway speed with cruise control engaged, the engine suffered sudden catastrophic failure with absolutely no prior warning, warning lights, knocking, stalling, or other symptoms. The vehicle became inoperable immediately. The repair estimate is $6,500 for engine replacement. The vehicle is a 2017 Kia Sportage equipped with a Theta II 2.4L GDI engine, confirmed by service campaign SC340 on file with the federal safety agency. Two safety recalls remain incomplete on this vehicle: 21V137 and 22V703. The Knock Sensor Detection System software update campaign SC340 was never completed prior to my purchase of the vehicle in February 2024 from a used car dealer, despite being issued in July 2018. Kia Consumer Affairs indicated the claim would likely be denied due to the incomplete KSDS update, despite that update predating my ownership entirely. A dealer appointment had been scheduled for June 26, 2024 to address outstanding recalls prior to this failure occurring.

What component or system failed or malfunctioned, and is it available for inspection upon request? Engine is malfunctioning, increase in oil consumption, MPG dropping, a ticking/knocking noise coming from the engine, and erratic engine behavior with random surges while driving to 6000+ RPM. Brought it into Kia 2x now for same issue and first time said nothing was wrong and second time I am now going through an oil consumption test. Vehicle is still unsafe to drive but they say this is the only option to do their test to move forward with my warranty with Kia. I am driving through mountain passes daily with this behavior and I worry if the engine blows I'll lose control of the vehicle and fall off the cliff. How was your safety or the safety of others put at risk? I am instructed to drive it still. Has the problem been reproduced or confirmed by a dealer or independent service center? The engine oil consumption test is happening now, I have driven 500 miles and the engine oil is low, pending to hear back from Kia on when they can get it in for next steps. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, just a Kia dealership (if that is the manufacturer then yes) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. And there is no warning lights for low engine oil. I have driven many times without oil and no warning that the oil was even low. The vehicle burns up oil fast.

I bought a 2017 Kia Sportage with a salvage title at auction on [XXX] for my wife, [XXX]. It had 57,463 miles on the engine. Before it reached the 60,000-mile warranty limit (only for non-salvage title vehicles), it showed error code P1326 and went into limp mode which makes the vehicle drive at a very slow speed to avoid damage to the engine. For an explanation of limp mode, go to the web address below: [XXX] Despite my wife's Kia Sportage NOT being under warranty, the vehicle's electronic system takes control and slows the vehicle making it unsafe for continued driving. Despite the KIA manufacturer no longer having a financial interest in a non-warranted vehicle, their electronics system prevents me from managing or using my vehicle. The dealerships will not do any repairs or bypass the control system and their only solution is an expensive engine replacement. 1. The Kia displays error code P1326 which is the subject of numerous complaints to dealers throughout the U.S. The problem is the KIA goes into limp mode with no remedy. Available for inspection. [XXX] While the lawsuit above refers to Ford products, the statement regarding loss of power significantly increasing the risk of a crash does pertain to my complaint against the KIA limp mode. 2. Risk - See link above 3.Archer Kia at 11614 SW Frwy. in Houston has confirmed and diagnosed the problem on 8-15-2024. 4. See #3 above. 5. The error code P1326 is the warning. Despite the KIA manufacturer no longer having a financial interest in a non-warranted vehicle, their electronics system prevents me from managing or using my vehicle. The dealerships will not do any repairs or bypass the control system and their only solution is an expensive engine replacement.

The vehicle went into limp mode while driving on the interstate but the dealership is telling me there is nothing wrong with the vehicle. They are also telling me that there is no powertrain coverage on this vehicle since I am the second owner. With as many problems as Kia has had, I think it should be across the board for coverage on these so no one else suffers irreparable damage. I’ve had the car shut down on me many times but every single time I’ve taken it in for diagnostic testing I’ve been told there is nothing wrong with it. I call BS. If there was nothing wrong with it, it wouldn’t shut down on me while I’m driving it.

I have taken my 2017 kia sportage in the dealer several times due to loss of power and hesitation when trying to accelerate. They always say they cant find any issue. Also, my Kia is using or losing oil. I get oil changed every 5000 miles and the last two changes I had less then the low mark, barely showing on dip stick. I have had to add quarts of oil after only 2000 miles since oil change. Oil light does not come on, even when showing no oil on dip stick. It is very scary when I go to accelerate and nothing happens when trying to get on on rap for highway.

Check engine light came on after I exit the ramp getting onto I-75. The vehicle started to stall. The vehicle started making a jerking move as though it was loosing power. I had to pull over in the side of the highway. I turned off the vehicle for about 5 minutes and turned it back on. I pull back onto the highway and noticed that when I press the gas it started repeating the same as I stated before and it wouldn’t accelerate pass 65 mph. When you slow down to about 20 mph and press the gas it stalls really bad as though it’s about to cut off. The acceleration hands jumps back and forth between 1 and 2 when pulling off.

We were driving steady at about 45 MPH and the RPM gauge rubbed at random just once every time. It has happened more than once we don't change your speed or anything it just rubs up to about 5000 RPM and go back to normal and does it sporadically
