KIA Complaints

** Component/system that failed: The engine and catalytic converter. An independent mechanic confirmed the catalytic converter is clogged due to engine oil burning and entering the exhaust system. The component is still in the vehicle and available for inspection upon request. ** Safety risk: The car struggles to accelerate, especially from a stop or uphill, and cannot reliably reach or maintain highway speeds. It revs at 3,500–4,000 RPM at just 20–60 mph. This creates a serious safety hazard, especially when merging, changing lanes, or avoiding traffic, putting myself and others at risk. ** Problem confirmed: Yes. A trusted independent shop diagnosed and confirmed the engine is burning oil, contaminating the catalytic converter, and advised against replacing the converter until the root cause is fixed, or it will fail again. The Kia dealership dismissed the issue without testing, claiming it’s acceptable to burn 1 quart of oil every 1,000 miles. However, my vehicle consumes about 1 quart every 500 miles despite routine 2,500-mile oil changes with 5W-20 high-mileage oil. This excessive consumption is abnormal and being overlooked without proper evaluation. ** Inspection by manufacturer or others: Yes. A Kia dealership inspected the vehicle but refused to perform an oil consumption test, claiming the vehicle was “too unstable to drive,” despite me driving it 20 miles there. They blamed the converter failure on “normal wear and tear,” and denied the presence of an oil leak. ** Warning symptoms prior to failure: Yes. The symptoms began months ago and progressed over time, including: loss of power, high RPMs under low speed, poor fuel economy (range dropped from 350 to 310 miles), and difficulty accelerating. No warning lights have appeared. ** Additional note: This issue closely mirrors NHTSA Recall 19V120, but my Soul has a 2.0L engine, not a 1.6L. Many 2.0L owners report the same problem. I believe this defect should be investigated for recall expansion.

Engine failed despite maintenance and repairs. The car is part of the active class action for Kia Engine Defects. The KSDS software was never installed as we were never notified about the recall by kia. As a result, Kia denied coverage under the engine defect class action settlement. We need this vehicle repaired or compensation for replacement

As I was driving at about 20 mph coming to a stop my passenger front door unlatched and caused the door to open and the door sensors to go off. This door was in fact locked and closed. Now I’m very scared to drive my car because if I was going faster the door could swing open and would be very dangerous to and to others.

I have received a warning 3 times saying “Rotary Shifter stuck. I searched and information says bring to dealer for immediate repair the brakes can lock and can cause an accident . I brought it in the first time and was told they can’t determine the issue unless the warning is on when I come in. It never happens when they are open. I read other stories and this problem is not just me having the issue. One person was told the same thing and his car has stopped in traffic and would not restart for a long time They need to find out what is wrong with the rotary shifter

My front windshield on my 2022 Kia Carnival has shattered in two places from a small hit. I have owned lots of cars and never had a windshield break in two places all the way across. There must be an issue or problem.

Brake pump failure caused the exhaust camshaft to break on the engine rendering the car inoperable. Engine replacement will cost over 8000 quoted by dealership. Car has check engine lights on the dash. We were advised by the mechanic at the dealership, they have had problems with the k5s with this issue.

The contact called on behalf of her neighbor who owns a 2017 Kia Soul. The contact stated that the vehicle failed to start. A mobile independent mechanic replaced the starter. The contact stated while the neighbor was driving at an undisclosed speed, the vehicle stalled. The driver was unable to pull over to the side of the road. The driver was able to push the vehicle to the side of the road with the assistance of bystanders. The vehicle was pushed to a business place parking lot, where the mobile mechanic diagnosed that the engine had failed. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 65,000.

I have now replaced the headlight bulbs in my 2016 KIA Sorento 6 times and it's getting worse as it gets older. I believe it is a safety issue since the last time I was out of town, traveling in the middle of the night when it went out. I had to wait until morning to find an auto parts store to buy and replace the bulb. No inspections have been done by anyone. Yes, the warning lamp comes on and stays until reset.

Purchased car about 4 months ago, before warranty ran out, the shop looked at it told me it was fine, it wouldn't accelerate. Few weeks later same issue but all my oil was gone, they found 11 things wrong with the vehicle, told me warranty wouldn't take care of it unless the engine blow up. The salesman Scottie Mitchell told me check Kia for recalls, called Kia 3 recalls, they were trying to finance another car higher, back wanted to know why the dealership didn't know about recalls, Kia place did call a Robert. One of the owners did know about recalls, why dealership didn't pass them on. They trying to sell me a higher vehicle to keep cover the cost of the one I got 1st

The paint on my 2015 Kia Optima is severely peeling off, especially on the trunk, hood, and driver-side pillar. The passenger side also has some peeling. This is not a minor cosmetic issue — it significantly affects the vehicle’s appearance and long-term durability. Many other owners of this model have reported the same issue, indicating a widespread paint defect. I contacted Kia through several official channels and received no response. I believe this is a manufacturer defect and should be addressed as a broader consumer issue.
