Kia Sportage slipping problems

Filed Jun 11, 2026 · Transmission · MN

I did not have an incident yet. I was advised by my local State representative Jimmy Gordon's office. They stated were unable to help me get reimbursement for the $8000 I just paid my Kia dealer, but that I should make a complaint on this website. What happened is that I was hearing an odd noise and it was slipping. I went in thinking it was my tires and it needed alignment- so I had them replaced , etc in April. But the sound was still there so I went back in . Then the Kia St Cloud dealer diagnosed that the AWD transfer case was the cause (pd $4704 including $130 surcharge! ). When dealer called to say it was ready, they said bad news- your transmission is also damaged (pd $3197 including $90 surcharge ! ). This is a known failure of Kia/Hyundai models and needs to be addressed. You can lose control of your car and there could be an accident, especially on busy highways! I appealed to Kia corporate and also BBB auto line, but they both denied because too many miles (130k). The sound I heard /issue with transfer case & transmission happened as soon as my powertrain warranty was over! This is not right! I was someone who had given this vehicle 5 stars! I am the only owner and a multi- Kia owner who only brought this vehicle to a Kia dealer for all work. I have all records and that info was why Kia corporate originally told me i had "justification " for a goodwill reimbursement. [I currently am unemployed so I had to put all the repairs on a credit card (which meant being charged a 2.9% surcharge without informing me at the counter!)]. I hadn't heard so called June 2nd to Kia customer care and they said it was denied after all and would not give me any info except that they had negotiated with the dealership and it came back denied! I tried to call the GM at the dealer , but no answer back from my voice mail to Hector. Then BBB AUTO LINE also told me ineligible due to mileage. Well, this is still a dangerous issue and needs to be addressed!

The oil was leaking somewhere not on the motor not under the car not blowing black smoke. I kept adding oil to it. No oil light. I was told not to park between 2 houses or in my garage it could catch on fire. I took it in several times and they did all kinds of stuff motor wash knock sensor was replaced wiring harness was corroded was slipping out of gear and other issues. And now it doesn't run because of the motor issue and they refused to fix it because I didn't have oil change receipts they are the ones that took care of that there was no oil to change I kept adding it. I have all of the detailed work invoices of what they did to it. I've been without a car for a year now they said it's not under warranty my car has several of the recalls. They wouldn't do all of the stuff they did if it wasn't necessary and trying to locate the problem.

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.

I am writing to formally raise a safety concern regarding my vehicle’s brake and rotor system, which has experienced premature failure on two separate occasions. First Occurrence: The issue was first identified prior to reaching 11,000 miles and was addressed by the dealership after surpassing 11,000 miles. The repair involved replacement of the rotors and bolts, but notably, the brake components themselves were not replaced. Second Occurrence: Around 23,000 miles, I began to notice progressively worsening shaking and a disturbing sensation of the brakes skipping or slipping—particularly during highway downgrades. By 24,500 miles, the issue had become significantly more pronounced. I returned the vehicle to Kia of Stockton at 25,248 miles. During my visit, Ricardo from the Kia of Stockton Service Department attributed the issue to “driver error,” citing hot spots on the rotors. However, he also acknowledged that during the initial repair, only the rotors and bolts were replaced—not the brakes. Ricardo further stated that Kia could not offer any additional support beyond a 10% discount on repairs, per his manager’s directive. I explained that I live and work locally, and my driving habits do not involve long commutes or frequent stop-and-go traffic. Given this, I strongly believe the repeated brake system failure points to a potential manufacturing defect rather than user error. Ricardo agreed that if this were his own vehicle, he would be concerned as well. This issue poses a serious safety risk—not only to myself and my family, but to other drivers on the road. In addition my vehicle has also experienced powertrain issues, where it feels as if the vehicle is stuck in 1st gear. I am therefore requesting a full investigation into this matter. If necessary, I would like to initiate the process of reporting this vehicle as a potential lemon under applicable consumer protection laws. Thank you for your attention to this urgent safety concern.

Transmission slips or hesitates when going from a stop to first gear. When turning left across oncoming traffic it is dangerous. The dealership looked at it and said that they couldn't get it to slip after having it for two days. No codes were thrown and no lights on the dashboard. Only slips occasionally like once a week. Always from a dead stop before going into first gear.

Driving at highway speeds the RPM would suddenly rev up very fast and the car would appear to be in neutral then soon go back to normal. On another occasion, taking a turn at 15 mph the car became as if in neutral, RPM would go very high, then shortly the RPM would drop and the car would be back in drive. The car was taken to the dealership, they checked it, noted that they could not duplicate the problem, and will not take any further action unless it repeats. The danger is if this occurs when driving into traffic, turning into traffic, driving on a freeway and the engine slips into the neutral mode, a collision can occur , risking injury, life and property. The only warning was the RPM going up very fast, and the car not reacting to pushing on the gas pedal. Attached is a PDF file that includes some summaries summaries of issues from web sites relating transmission problems of slipping into neutral.

Intermittently, the car’s transmission slips out of gear completely, around 30-40 MPH. It gets back into gear after a few seconds. At times, it has presented a safety risk especially when attempting to merge on a highway in a short merge lane. When the slipping occurs in this situation, the car no longer accelerates and merging into traffic becomes very problematic and increases the risk of a rear end collision, putting me and my passengers at risk as well as a risk to others The problem has not been reproduced or confirmed by the dealer. It started occurring immediately after I purchased the car used while still under the manufacturers warranty. Because the dealer service department could not replicate the issue, no further attempt to diagnose the issue has been conducted, such as a transmission tear down. I’ve taken it to the dealer at least 3 times for this issue and have documentation. I elevated the issue to the manufacturer but they have offered no solution to the issue because it cannot be replicated by the dealer and there is no recall or other service issue with the model. Melissa from the KIA Escalation Department contacted me today offered no resolution to the matter. There were no warning lamps or other messages which indicated a problem. The Kia Forum website reveals that I am not the only one with this issue. https://www.kia-forums.com/threads/transmission-slipping.288137/page-5
