KIA Complaints

The lane assist malfunction and periodically jerks. Very unsafe I no longer use this feature . To keep control of the vehicle. I never got it inspected. As the lane assist was in use and it would jerk it would alert me of a lane departure . I mention this to include every known problem I have experienced with the vehicle. The problem That brought me here. Is my engine light came on today. Leading up to this. I have had oil leaks since I've owned the car. Im adding oil in between oil changes due to it being low. In the beginning it was a hint of smell of gas in the oil. I was informed to do more frequent oil changes. Over time the smell of gas grew stronger . No Indication to a problem then. Now the smell of gas is prominent in the oil. When the dip stick is checked its always needing more oil and smells of gas and has blackness like burning in the oil. Now there's a check engine light on. And everything I looked up says to discontinue driving the car. I am having a mechanic look at it with a code reader.

The contact owns a 2025 Kia K5. The contact stated that while her daughter was driving at an undisclosed speed, the Tire Pressure Monitoring System (TPMS) warning light illuminated. The contact's daughter took the vehicle to a specialty tire shop, and it was determined that the front driver’s side tire had two bubbles. One bubble was located on the top, and one bubble was on the front side. The tire was replaced. The tire manufacturer was made aware of the failure and referred the contact to the vehicle manufacturer for assistance. The failure mileage was approximately 2,500.

My 2016 Kia Soul is experiencing severe oil consumption, piston ring failure, and smoke from the exhaust. The vehicle is covered under Kia’s engine warranty extension (Product Improvement Campaign PI2002B and subsequent updates), which extends coverage to 15 years/150,000 miles on the engine short block/long block assembly. The dealership confirmed the failure is due to piston oil rings, but Kia America has denied warranty coverage, stating that because the rod bearing clearance test passed, the repair is not covered. This denial contradicts Kia’s own documentation, which defines the covered “short block assembly” as including pistons and piston rings, in addition to bearings and connecting rods. By refusing coverage, Kia is effectively narrowing the warranty in a way that leaves consumers unprotected, despite the campaign language. This issue raises a safety concern because excessive oil consumption and piston ring failure can lead to: Engine smoke and emissions problems, Sudden power loss, and Increased risk of engine failure while driving. I am requesting that NHTSA investigate Kia’s handling of piston ring and oil consumption failures under the engine warranty extension, as Kia appears to be limiting coverage only to rod bearing failures, despite covering the entire short/long block assembly on paper. Summary: VIN covered under PI2002B/KSDS update. Engine is consuming oil and smoking due to piston ring failure. Kia refuses coverage because rod bearings passed the clearance test. Piston rings are part of the short block, yet warranty is being denied. Safety issue due to risk of engine failure and increased emissions.

The design of the backup light is awful. There is a single light that is about two inches long and an inch high under the license plate. When you back up in a parking lot like at Walmart, other drivers cannot see the light and keep driving by like you are not moving. We have had several close calls because of this. Kia should be forced to change the design

Driving 70mph on the freeway and check engine light started flashing. Car immediately went into “limp mode” and within a few hundred feet went from 75mhp 30mph. Used ODB reader and code p1326 came up for “engine knock sensor”. Engine was two quarts low on oil. No low oil warning. I just had an oil change a month ago and there is no apparent oil leak. When I opened the oil cap small amount of smoke was visible coming up from engine. Car has 75400 miles on it. I reset the code, put 2 quarts of oil and drove 2 miles to a Kia dealership. The said they couldn’t look into it since I reset the code. I drove another 4 miles and the same code and symptoms showed up. Having my car towed home because the dealer can’t inspect until next week. Other Kia’s have had this same error code and were recalled with engine replacement.

The contact owns a 2019 Kia Sorento. The contact stated that while driving at 70 MPH, there was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where an oil change was performed because the engine oil level was extremely low. The contact stated that the vehicle was not due for an oil change at the time of the service. Despite the oil change, the failure worsened as the sound became increasingly louder. The vehicle was then taken to another independent mechanic and was diagnosed it with engine failure, and the contact was provided an estimate for a new engine. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 164,000. The VIN was not available.

Basically since I bought this car back 2020, brand new, the engine loses oil. Vehicle even stalled in the middle of the highway because there was no oil and no warning at all. Kia dealership tells me over and over that there is nothing wrong with it, after doing oil testing for 1000 miles. They have replaced components but nothing has worked so far. Latest issue that after 2700 miles from an oil change, I had to fill it up with oil. Now my car has about 57000 miles on it.

Every time this issue happens, ALL the safety warnings are going off on my dashboard, telling me to check each safety feature and that it's currently NOT working. 1 - Check AWD/4WD 2 - Check Blind Spot Safety System 3 - Check Tire Pressure Monitoring System 4 - Check Smart Crusie Control System 5 - Check Forward Side Safety System 6 - Check Rear Cross Traffic Safety System 7 - Check Lane Following Assist System 8 - Check Lane Change Assist Function 9 - Check Lane Safety System 10 - Check Speed Limit System 11-Check High Beam Assist System 12 - Check inattentive Driving Warning System 13 - Check Door System 14 - Check Truck Lift gate System - ALL going off while I also LOSE MPH and Turn Signal capability and cameras.

got into my vehicle pushed button to start, could hear a clicking for the first few seconds, then clicking went away. Drove off, went approximately 0.30 mile at a stop light when started to go it stalled in the the middle of an intersection. No warning light no other warning of anything wrong with vehichle, no other warning signs that there could be anything wrong. In July 2025 I had just took vehicle in for a major maintenance, oil, air filters, spark plugs, timing belt, and I checked oil and again no warning signs that there was anything wrong with vehicle. Took to a shop, mechanic believed it was the key fob, due to immobilize, had a new key reprogrammed and still not start, then proceeded to check the starter and installed a new starter still not start and found to be engine siezed.

Everytime i put my car in cruise control for 1-2 minutes after i take the cruise control off the breakers are gone and them come back
