I had all four of my window regulators to go out within two days of each other and now my windows constantly drop automatically while driving especially if I go over speed bumps, hit pot holes or any type of bump. I try to keep them up by placing paper or holders in them but they only hold up for so long and at times when I-??m driving they drop down and I-??m afraid the glass will break completely because one of them dropped while driving and the window cracked. This is a very dangerous situation and Kia tried to charge me when I went to them and I know this has to be a defect for all windows to go out.

All four windows stopped working within two months of each other. The motors still work, but the plastics parts inside broke. The trunk latch also stopped working and the trunk won-??t stay shut. There are recalls on the 2016 Optima for the trunk latch, but the dealer says my VIN isn-??t involved. There are also tech notices for the windows on the 2016 Kia optima, but no recalls yet. There is a class action lawsuit for the windows also for safety reasons. No one would be able to get out of the windows or trunk if the car were in an accident because none of them work. Kia is useless to fix their junky cars. The mileage is 70,000.

Both rear windows, independently and at different times, have needed to have the gear inside the door panel that rolls the windows up and down replaced due to spontaneous stripping and total failure. The dealer has replaced the offending parts, which are sold only as part of a much larger / very large component panel, i.e. it is not possible to replace only the small plastic stripped-out gear. My safety was at risk both times because the window would not go up, resulting in my inability to lock and secure my car. If I had small children who ride in the back seat (I don't, but surely others who have this car do), I would not be able to secure their safety inside the vehicle. The problem has been inspected, confirmed, and repaired by the dealer. It is a known recurring problem by the manufacturer Kia, but they refuse to issue a recall. The first time it happened the car was still under warranty so there was no charge to me. With the second window the car was no longer under warranty and I had to pay the full cost of the repair. There were no warnings of pending failure; the windows were rolled down and just failed to roll up. I wish to state for the record that although this is a 2016 model and therefore is now 7 years old (in 2023), it has only 14,000 actual miles on it, i.e. I drive the car only around town for errands, etc. From 2017 (when we purchased the car) through mid-2020, I drove it 18 miles per week to my part-time job very near my home. I retired in mid-2020 and drive the car even less now. Furthermore, I've had riders in the back seat probably less than a dozen times in 7 years, my point being that the rear windows are rarely used. Mostly they have been used by me as the driver when I want to release built-up heat from the car when it has been sitting all day in the NC summer sun and I'm going out once or twice a week to drive it somewhere (like the grocery store). This failure should not be happening with a car with so little usage on it!

My daughter was driving on the interstate and her car lost power while driving. This is a major safety issue. A car losing power in the middle of 80 or higher mph traffic could result in fatalities.

My kia Burns lots of oil. I'm having to refill oil every 300 miles. And the oil isn't on the ground. It's burning out on my sparkplugs and oil pac coil. It's even shut off engine light came on. Got it towed to SONS of Kia. Had it diagnosis and Was told it's needed sparkplugs and coil pac replacement. Full tune-up. Oil change. Later. Having the same issues. Having to continue replenish oil. Over and over. Where is it going. Oil sputtering out of my tail pipe. Oil and water from tail pipe. Took it to Amoco Transmission. For diagnosis and was told that this need to be reported to kia. A major recall. Oil is burning from engine issues. My sparkplugs are loaded with oil and coil pac. Why I've always got my oil changed every due time. Later after 300-400 miles. I'm having to add oil again. Something wrong with this. I travel and my wife have to check oil consumption every week to make sure oil is in the car. She's very stressful about this situation. The car be studder when this happens. And some time want crank. It's nothing of her end. It's the manufacturer of the car. Burning oil consumption. AND NOW ITS AT AMOCO TRANSMISSION WAITING ON WHAT'S NEXT. TRULY WILL LOVE KIA TO DO THE RIGHT THING. MY WIFE LOVE'S HER KIA. AND ARE THINKING ABOUT BUYING A SUV FROM KIA IN THE FUTURE. My other paper work are in the car. Will update more information later.

We received a recall notice for our KIA Optima to get the software upgrade to restrict operation of the vehicle without a key. We took the car to the dealership on 5/5/2023 for the recall and picked it up on 5/5/2023 from the dealership at 3:30pm. On 5/8/2023 our car was stolen out of our driveway. It was recovered on 5/12/2023 by our local police dept. and it was stolen by using a USB cord and starting it without the key. Obviously the recall does not work. There is now damage inside and out of my car. I did notify KIA corporation last week that it had been stolen and have not heard from them. I also sent an email this morning letting them know that the car was returned and confirmed that they stole it they way the recall was suppose to fix so that it could only be started with the key in the ignition. Obviously that did not work.

I was disappointed but it was what it was there in about a month and a half later the rear passenger side, the rear driver side stop going up and down and then a week after that, the driver side front step going up and down if I knew it, none of my windows would go up and down if my air conditioner goes out, I am, in trouble I live in Florida I cannot drive without air-conditioning or through the windows being able to go up and down. I made a complaint to Kia. They hung up on me neither Kia nor Honda where I purchased his car wants to do anything to assist me I have read the door multiple complaints regarding the windows and his cars. Why isn-??t anything being done ?

The vehicle was sold to me with a known recall issues. I have taken it to the kia dealership close to me during the recall time period. They never told me about this issue coming up on their system. There was a certain time period that the recall was supposed to fixed, now kia is telling me that it's my financial responsibility to fix.

I purchased this vehicle about a year ago upon purchasing vehicle I noticed I was having to get an oil change every other week and when I would go in I would have no oil. Fast forward to now I am buying 5g oil from Advance Auto parts every week my car is burning through oil excessively and causing my sparks plugs and coils to go bad from the oil. I have had to get my coils and sparks plug replaced three times in 5 months. I took the vehicle to get an oil consumption test at the Conway Kia dealership and they said nothing was wrong which is inaccurate because no car is burning 5 g oil each week. My car is currently at 80,000 miles I know once it reach 100,000 my warranty voids and at that point Im left with no recourse on this vehicle

On Sept. 21, 2021, my Kia Optima Hybrid ex shut down and would not start. I took it to King of Hybrid EV Auto Repair where they ran a diagnostic test and found that there was an issue with the Hybrid System affecting the transmission and the High-voltage system. I paid $3,000 out-of-pocket. On October 26, 2022, while driving 75mph on Hwy 15 to Las Vegas, my car randomly shut down. The dash warning lights read "STOP VEHICLE TO CHARGE BATTERY". I was in an unsafe position with cars speeding past me. I was afraid that I would be rear-ended by another car. I had to have my car towed. I believe that these cars have issues with faulty high voltage systems and transmissions. Please investigate. Thank you.

The contact owns a 2016 Kia Optima. The contact stated upon activating the heater while driving, she smelled an abnormally strong gasoline odor. There was no warning light illuminated. The contact related the failure to Kia Independent Recall Campaign Number SC172 (High Pressure Fuel Pump Outlet Inspection). Additionally, the contact stated while driving and depressing the accelerator pedal, the vehicle hesitated to respond and then lunged forward abruptly. There was no warning light illuminated. The contact stated that the failure had been reoccurring while driving. The dealer and the manufacturer were notified of the failure and informed the contact that she needed to pay for a diagnostic test and the repair cost because the VIN was not included in any recalls. The vehicle was not diagnosed or repaired. The failure mileage was approximately 110,000.

On Saturday, 09/17, I took my vehicle in for a standard oil change & alignment with a 3-party mechanic (pepboys). Once the work was done I was informed by the mechanic that the Driver's side window was in the down position and would not go back up. I was informed that it was because the Regulator went out and it is a Kia only part. Kia is unavailable on the weekends so they would get the part on Monday. On Tuesday, 09/20 Pepboys was able to get the part and repair the window to the tune of $822.67. The part alone was $542. Today, Thursday, 09/22 on my drive into work the back Driver's side window began to slide down while I was driving. This is a severe safety hazard that needs to be address by Kia. The Window Regulators will fail without warning & while the vehicle is in motion. I have 60k miles, this is not a high mileage vehicle.
