KIA Complaints

The infotainment system in my Kia K5 has failed completely. The screen went black, causing the radio, infotainment features, and backup camera display to stop functioning. At times, the system will attempt to reboot on its own, but it does not return to normal operation and continues to malfunction. I have attempted to reset the system multiple times using the available reset methods, but none have resolved the issue. I took the vehicle to my local Kia dealership, where I was informed that the radio/infotainment unit itself is defective and needs to be replaced. The loss of the backup camera display is particularly concerning because it affects visibility and safety while reversing. I have also found numerous reports of similar infotainment and radio failures involving Kia vehicles, which makes me concerned that this may be a widespread defect rather than an isolated failure. I am requesting that this issue be reviewed and investigated as a potential vehicle defect.

AC not working, recall SA512 is needed, Kia wont cover the cost of replacing electrical components. Thermal Runaway / Fire Risk: The broken compressor prevents the battery thermal management system from cooling the main high-voltage lithium-ion battery package, creating an overheating hazard during driving or DC fast-charging. Sudden Loss of Power (Motive Power): Battery overheating can trigger a sudden "safe mode" or turtle mode, dropping your speed to zero unexpectedly on the highway.Impaired Driver Visibility: The lack of functional cabin heating prevents windshield defrosting, severely impairing the driver's ability to see the road safely.

All of the ADAS you have listed stop working on my car. I will be driving my car, stop at a red light, drive through, or just driving down the road and it starts throwing sensors. It won’t even show the MPH I’m driving and some times the steering wheel locks up, as does the car itself. I can’t shift gears, move the vehicle, or anything until leaving the vehicle alone for a while and coming back to it. I have proof of multiple repairs, call ins to Kia, and even a request for buy back which was denied on the vehicle.

I went to honk my horn as someone was backing up and didn’t see me as we were on an incline . This vehicle sits low and they were in a jeep. Due to the failure of my horn, I was unable to give a warning and they hit my car. No airbag was deployed and my seatbelt/airbag light is on. No injuries reported thankfully. I was told these things were related and repairs needed which is going to be extensive. The airbag may not deploy and horn does not work. I consider this a definite safety issue.

I purchased a used 2025 Kia Soul with approximately 12,930 miles on the odometer in July 2026. Prior to Friday, August 1, 2026, I had not experienced any warning lights, warning messages, drivability issues, or other symptoms. The vehicle appeared to operate normally. On August 1, 2026, as I pulled out of the parking lot, the car surged or lurched forward while pushing on the gas. I pulled over, and the engine RPM still would increase on its own while the vehicle was in park, and and while stopped with the brake pedal applied. On one occasion in traffic a week before, the vehicle stalled unexpectedly. At the time I thought I did something wrong and didn't initially think it was a defect. This has created a safety concern because the vehicle appears to accelerate or push forward without me doing anything. The condition raised concerns about maintaining control of the vehicle in traffic and while stopped behind other vehicles. The vehicle was inspected by a Kia dealership. I was informed that a technician performed a road test and was able to reproduce the concern I reported. The dealership initially identified contaminated A/C refrigerant and recommended evacuation and recharge of the A/C system. After further diagnosis, I was informed that the A/C compressor may have internal damage and may require replacement. The root cause of the unexpected revving, stalling, and lurching has not been conclusively determined. I have received conflicting information regarding whether the A/C system is responsible for the condition and whether the vehicle is safe to drive. The vehicle is available for inspection upon request. Kia Customer Care reviewed the situation and recommended that the vehicle be evaluated by a different Kia dealership for a second opinion. No police report or insurance investigation has been conducted regarding this issue. Someone advised me to file this report, saying that an AC compressor can't make a car engine lurch.

The contact owns a 2019 Kia Sedona. The contact stated that while operating the vehicle, the check engine warning light illuminated, and the engine overheated. The vehicle was driven to the local dealer, who diagnosed that the engine head bolts had failed. The contact was informed that the engine needed to be replaced. The engine was replaced. The contact stated that later while driving at an undisclosed speed, the vehicle stalled. The vehicle was towed back to the dealer who diagnosed that the ignition coil had failed. The ignition coil and spark plug seals were replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 146,000.

I purchased this new 2026 Kia Seltos with approximately 32 miles. The vehicle now has fewer than 600 miles and has experienced two incidents of sudden, intermittent, complete loss of accelerator response. During one incident in highway traffic, the vehicle unexpectedly began decelerating and pressing the accelerator pedal produced no acceleration or meaningful propulsion. I could not maintain speed or accelerate to move out of surrounding traffic. The vehicle became unable to move normally until it was turned off and restarted. An oil-pressure warning light illuminated during the failure. There was no meaningful warning before the loss of acceleration. After the first incident, an authorized Kia dealer found diagnostic code U200300 only in the vehicle’s history. The dealer attributed the condition to a loose right battery cable, repaired or tightened the connection, and returned the vehicle as fixed. The same loss-of-acceleration condition occurred again after that repair. On July 13, 2026, an authorized Kia dealership technician personally reproduced the failure during a 30-mile test drive. The technician documented that the vehicle felt as though it died during acceleration and that pressing the accelerator would not make the vehicle go anywhere. No diagnostic trouble codes were generated or found during this dealer-confirmed failure. The dealer and Kia Techline inspected the vehicle. The dealer documented proper oil level, no obstruction in the air filter or throttle body, no visible leaks, approximately 50 psi of oil pressure at idle, and no visible corrosion or damaged connector pins. The diagnostic records provided to me end while Kia Techline was still asking about the oil-pressure sensor. I have not been provided with a confirmed root cause or documentation showing what specific repair permanently corrected the loss of propulsion. The failure creates a serious crash risk because the vehicle can suddenly lose all useful acceleration in highway traffic, l

I am writing to escalate an unresolved issue regarding a Voluntary Emissions Service Campaign performed on my vehicle at Bulldog Kia on July 14, 2026. Shortly after leaving the dealership, my Check Engine Light illuminated. An independent mechanic scanned the vehicle and confirmed that the active fault code directly relates to the components/logic altered during the corporate emissions campaign. I have called the dealership multiple times over the last few weeks and left voicemails for two different service representatives, but my calls are being ignored. I also contacted Kia corporate customer service who responded saying that they could not do anything and that I needed to continue contacting the local dealership (Bulldog Kia). From what I understand this could be a safety issue because it prevents me from being alerted to other safety issues that would trigger the check engine light, and there are also ways in which this could potentially cause the vehicle to slow way down or stop running while driving. As noted above the dealer has been unresponsive to my repeated contact attempts and the check engine light remains illuminated.

Fuel evap canister leak was suspected due to very strong gas smell inside vehicle. Dealership had to change out entire fuel tank to deal with whatever was leaking. Got the car back, and the next day, the smell was back. Dealership told us not to worry about the smell, that it was normal. Drove one more time and smell was so strong that it made two adults dizzy and nauseous within five minutes. Nausea lasted multiple hours. Parked and had it towed to dealer. After multiple days, still waiting to hear back, service apartment claims they're waiting for research from Kia. Vehicle has been too dangerous to drive so sitting at dealership for nearly 30 days now, total. No warning lights or messages ever came on to notify us of the problem.

In August 2025, my Kia dealership serviced my 2021 Kia Telluride and billed me for 7 quarts of oil as part of the repair. Approximately four months later, in December 2025, the vehicle developed severe engine problems and became inoperable. The dealership diagnosed the failure as a collapsed timing tensioner and stated the engine required complete replacement. Kia Techline agreed with that diagnosis and used it as the basis for recommending a new engine. Despite acknowledging that engine replacement was necessary, Kia denied warranty coverage, leaving me responsible for an estimated $11,000 repair. I then obtained a second opinion from an independent, reputable repair facility. After inspecting the vehicle, the shop concluded the engine failure was not caused by a timing system failure. Instead, they found the engine contained only about one quart of oil and determined the damage resulted from oil starvation. They further stated that, in their professional opinion, the dealership had misdiagnosed the vehicle and that the low oil level was consistent with the possibility that the dealership failed to add the oil for which I was charged during the August 2025 service. What is especially concerning is that the dealership never documented or informed me that the engine was critically low on oil. Because the timing components rely on engine oil for lubrication, I believe it would have been impossible to properly inspect and diagnose a timing tensioner failure without recognizing and documenting the severely low oil level. Based on the independent inspection and the dealership's failure to identify or disclose the lack of oil, I believe the dealership either failed to perform the service as billed or failed to correctly diagnose the true cause of the engine failure. I am concerned that this incorrect diagnosis diverted attention from possible negligent workmanship during the prior service and led to an unnecessary recommendation for an $11,000 engine replacement.
