KIA Complaints

Oil pressure sensor failure on the engine, there is an open TSB for this same issue/same engine on other Kia models but not the Stinger. Dealer verified that the oil pressure is fine and that it is the sensor, independently verified by a third party shop. Dealer charge is over $3k for the repair and third party is just about $2k.

The vehicle is suffering from a chronic, cascading powertrain and fuel management defect that has resulted in a critical safety hazard: sudden engine stalling. Over the last 17,000 miles, the vehicle has experienced three severe engine/emissions failures that the manufacturer has been unable to permanently resolve. At approximately 30,000 miles (on 29-Jun-2025), the engine suffered a severe Cylinder 3 misfire (Code P0303). At approximately 39,000 miles (on 02-Jan-2026), the unresolved fuel issue caused a failure of the Catalytic Converter (Code P0420) and an Evaporative Emission System leak (Code P0456). At 47,000 miles (Current Event), the fuel delivery system failed completely. The engine began running excessively rich (Code P2178), causing the engine idle to drop dangerously low (Code P0506). This defect caused the vehicle to suddenly stall out, resulting in a complete loss of motive power and leaving me stranded. Because the manufacturer's authorized repair facilities have only addressed the symptoms rather than the root cause of the fuel system failure, the vehicle repeatedly loses power and stalls without warning. This poses a severe safety risk to myself and other motorists, especially when operating the vehicle in traffic or at highway speeds.

The sunroof failed and is stuck open. This creates a hazard as you cannot secure the vehicle, it is open to the elements, and you have highway noise. This is not a simple small motor fix it is $3000+ and a complete replacing of the track/cassette.

Not due to recalls. My entire car was malfunctioning over the backup camera. Every system was being displayed on my dashboard as all lights were on. Turning signals and four ways would not work, my steering became tight and hard to turn.

The contact owns a 2022 Kia Niro. The contact stated that while driving from a complete stop at 5 MPH, the vehicle was T-boned on the passenger's side by a Jeep Grand Cherokee driving at high speed. Due to the impact, the contact's head struck the dashboard. The other vehicle fled the scene of the crash. The airbag deployed on the passenger side but did not deploy on the driver's side. No warning light illuminated. There was no reported fire. A police report was filed. The vehicle was towed to a tow lot, where the contact was informed that the vehicle would be destroyed. The contact sustained an eye and face injury, body aches, and a detached ear. Medical attention was received at the hospital, where the contact was stabilized and referred to the Primary Care Physician for future care. The contact called both an unknown local dealer and an independent mechanic, but there was no response. The manufacturer was not contacted. The contact called the auto finance company and was referred to the insurance company. The failure mileage was unknown.

The vehicle experiences a recurring mechanical failure where the electronic AWD coupling/rear axle locks up and binds when accelerating through turns. This creates an immediate safety hazard by altering steering dynamics and causing vehicle hesitation or severe wheel hop in intersection turns. A certified Kia dealership has already fully replaced the entire factory AWD Coupling assembly twice: first under the original warranty on July 16, 2024 at 48,054 miles, and again under warranty on May 2, 2025 at 59,350 miles. Following a preliminary check-in for the same symptom on April 9, 2025, this identical component failure has now recurred for a third time at approximately 77,000 miles.

Usually the car would be taken to a shop for an oil change and I did it myself last time and realized the oil was pretty low. I checked over the weekend and noticed the dip stick marked the oil as 2/3 full after waiting 10 minutes for it to cool down a bit. This is alarming because when I filled the oil it was close to the max level.

The tire separated after only 20k miles. Mechanic stated that I still had half of the tires life left. Was advised not to drive more than a mile on it as it could blow out and cause harm to myself and 2 young children. I had two new tires put on the vehicle. My mechanic will be checking the two remaining at every oil change I have in the future. There was no warning, my vehicle started violently shaking and veering heavily to the right, so much I had to fight it with both hands. Kumho (tire manufacturer) has ignored my calls and emails. Kia told me they cannot help me and to reach out to Kumho.

I was driving down the highway when I kinda noticed speed changed. ABS lights, foreword collision light, and rear end lights, so I turned around went back home. I rarely drive my car and I never had any problems with it. I purshased it brand new.
