2016 KIA OPTIMA Complaints

Oil started leaking from the car and checking underneath it looked as though it was leaking from the plug so i replaced the plug, which did not fix the issue, and accidentally forgot to put the gasket back on. took it to the local shop was given a gasket and an oil change. the car started leaking oil worse than before so i took the car back. The oil pan had a little over an inch long crack on the corner/edge where the oil pan plug is. Mechanic told me he’d never seen or heard of a steel oil pan cracking before. $400 for a new oil pan made from below par steel.

My 2016 Kia Optima has been consuming oil every 1.5months. I have multiple times had to replace my oil because my oil light kept coming on. I’ve checked it every single time and it is barely anything there. I have my breaks mess up and not work as properly with my safety and others being comprised. I have brought this up to my Kia dealership but they have just brushed it off and charged me for an oil change. I have seen and heard many cases like mine and it has happened worse to them to the point where the car stops in the middle of the highway. My car has been checked by others and they have all noticed the same thing - the oil levels extremely low only after 1 and a half months or way prior to when my next oil change should be made. Having this happen is expensive and life threatening when the brakes don’t work as they should or when my could possibly bust. I have received no help and would like to make this known .

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!

This 2.4ltr engine burns 1 quart per 1000 miles! 53769 miles, Kia claims not under warranty and wants over 600 dollars for an engine flush! KIA OF PORT CHARLOTTE FL. They filled my oil too much! It is at least a half a quart above full! They also filled the Kia with 5-30, I do understand that from book and temp. Ranges. Found PCV valve partially defective and replaced that... Can you help me understand why I have no warranty under 54,000 miles and why engine is not covered under 100,000 miles? Also, is this defect acceptable to the NTSB? It has caused multiple accidents due too engine failure and seizing Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crack in dash along outline of airbag. Burns oil so it has to be refilled monthly Now mechanic says compression and combustion are problems Can’t get into Kia until February when warranty will probably be expired

I have already had to have motor and transmission replaced once under warranty. The replaced transmission was worse than the original problem. The original problem was hard shifting. Now I have intermittent hard shifting, occasional lunging forward, occasional shuddering while pressing accelerator, and feeling like there is hesitation to change gears. I have not taken it back to the dealer yet. I always get the excuse that they cant replicate the problem. It took me 2-3 years to get it acknowledged the first time.

My high beams and low beams are starting to shut off randomly. When it happens, my dash shows that i am trying to turn my headlights from auto to another setting, which is not the case. It has happened at night and that poses a danger because i cant see the road and people cant see my car. I have not had it looked at yet. I do see multiple complaints online for multiple different kia models and years. There is no recall and i do not see a TSB.

The 2016 Optima SX Ltd is consuming oil, but no leak can be found by the mechanics. It is available for inspection upon request. Had the motor seized, I would have been stranded on the side of the road. I have all the CarFax Service records. It is serviced IAW Mfg recommendations. The oil light flickers and turns off at starting. A service engine in 30 days light came on. Took it to change the oil and there was NO oil in the vehicle. The oil and filter were changed, the engine cleaned and no leak could be detected. One week later the engine oil light flickered on and the oil was checked. It had consumed 1.5 quarts of oil in one week. There are zero oil stains in my driveway where the vehicle is parked every single day. This problem has been reported on multiple complaints NHTSA ID#s 11539081, 11538898, 11538679, 11538029...since August 1. Kia should issue a recall or investigate why the vehicles are consuming so much oil that leads to engine damage/failure with occupants stranded on the side of the road. Why is the oil light just flickering on and then off and not staying on if the oil is low? Please help.

The contact's son owns a 2016 Kia Optima. The contact stated while his son was driving 35 MPH, the vehicle stalled. Several unknown warning lights illuminated. The contact stated that his son was able to pull into the driveway. The vehicle failed to restart. The vehicle was towed to an unknown dealer, where the failure could not be duplicated; however, the dealer informed the contact that the failure could be related to the engine rod bearing. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure and referred the contact to the dealer. The failure mileage was approximately 170,000.

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.
