    CAR CHECK ENGINE LIGHT TURN ON AND STARTED TO SHAKE REALLY BAD WHILE DRIVING LIKE ITS GOING TO TURN OFF, AND SHAKES EVEN MORE WHEN I MAKE A STOP AND LOOSES POWER TO CONTINUE DRIVING. ALSO IT BURNS OUT OIL REALLY FAST I HAVE TO KEEP PUTTING OIL ALMOST EVERY TWO WEEKS

  8. Engine, Jun 19, 2024

    Check engine light came on and car started shaking pretty back than completely turned off.

  9. Engine, Jun 18, 2024

    My vehicle is consuming excessive oil. I have to keep oil in my trunk to replace oil regularly. My car is a 2016 Kia Optima and has about 58,000 miles on it. I have reached out to Kia on several occasions including consumer affairs and voiced my safety concerns about the vehicle and potential of the engine seizing due to oil loss and concern of a potential vehicle accident as a result of an engine seizure while driving. I asked for an oil consumption test to be performed on the vehicle because of its excessive consumption and was told that the oil consumption test only applies to the 1st owner.

  10. Fuel/propulsion system, Jun 16, 2024

    In May of 2023, as I entered an intersection, my 2016 Hybrid Kia Optima suddenly did not feel right and gave me a hybrid system warning error. I pulled to the side of the road and shut it down. I restarted the car. The error light remained on, but the car seemed to drive okay. I finished my short distance into work, and shut it down. I called the dealer and was asked to restart it to see if the hybrid warning light came back on. I restarted it after lunch, and no warning lights came on. The dealer had me bring it in to the service department. They had it for a week or two but could not repeat the problem. They updated the software and thought that might fix the issue. The car worked fine until September 2023 when it suddenly cut out on me as I was turning a corner in my development with the same hybrid system warning error. I was able to glide to the shoulder. I restarted it and drove home with the error warning light. This time the dealer had the car towed into their shop. They had the car for a few weeks but could not diagnose the issue and gave the car back to me with a “trigger” system to monitor for codes. In about a week, the same warning light popped on my wife who pulled over and shut it off. She restarted the car and drove the remaining short distance to work with the hybrid system warning light on. Later that day, it restarted without the hybrid warning light coming on, and I drove it the short distance to the dealer. It took about another month until mid-November to diagnose the problem as a defective hybrid battery and order the under-warranty replacement. Here it is in mid-June 2024 and I am still waiting for a replacement hybrid battery. I no longer trust the car or Kia Corporate, and I haven't been able to get Kia Corporate to respond to me in over a month. Hopefully, no one else is involved in an accident due to this model car cutting out on them.

  13. Power train, Jun 10, 2024

    My 2016 Kia Optima LX 1.6 has been burning oil really fast. It also has been losing power when I try to accelerate with know check engine lights on. Currently the engine has a shake to it & is un-drivable. Oil gets to the spark plugs. I previously took my car to a Kia Dealership before I had a check engine light. They told me they could not do anything because a check engine light was not on. Now that a check engine light is on I was told by a dealer that it has an engine misfire. It has been seen by a dealership. This problem could have been prevented now knowing that this is a problem for many Kia automobiles.

  14. Vehicle speed control, Engine, Fuel/propulsion system, Jun 9, 2024

    Car was at about 70,000 upon purchase. Once driving it regularly, I immediately noticed a faint knocking noise upon acceleration. Also, when coasting the speed adjusted on its own intermittently, both up & down, not by much but enough that I felt it on the gas pedal. Other times it fails to accelerate when pushing on the gas pedal. I have to release the pedal & try again, sometimes more than once before it finally accelerates. Despite doing regular oil changes, my engine burns through oil long before next oil change is due, so I have to add 1 - 2 quarts of oil in-between changes. I was barely at 80,000 miles when engine started seizing & the following day the check engine light came on. It had to be towed to be serviced. They said the fuel injector or pump (not sure which) was allowing fuel to flood my engine which caused its damage. Even with what the warranty covered I had to pay $500 out of pocket so there were a lot of repairs. I can get a detailed print out of service if needed. When I do oil changes there's oil under the oil pan somehow, but its not leaking because there is no oil where I park. As of lately, even though all fluids are good, when the car is idle with a/c on, the temperature starts to go up until the car is in motion again, then the temperature goes back down quickly. It has only overheated once, which was the first time I noticed the problem because I was parked at a gas station on a hot day checking my phone & the a/c started blowing warm & dash said, "engine overheated". Only happen the one time because I have been cautious about watching the temperature to avoid it happening again. I recently passed emissions & had AutoZone do code reader check & nothing came back. In order to figure out problem I'd have to get diagnostics test that requires I leave the car for at least 2 days so it hasn't been something I can manage yet. My car is available for inspection if needed & I'm happy to provide detailed print out of repairs if requested.

    Vehicle uses about 4 quarts of oil every 1000 miles. I have to get oil changes every 1500 miles and add oil every 1000 miles. The car is not reliable and oil light comes on every 1000-1500 miles after oil change. Today the emissions light came on and I could not drive over 60 mph, after taking it to mechanic it was over 3.5 quarts low of oil but no oil light came on. The mechanic put 3.5 quarts of oil in and I had to pay for oil and labor, also to put the car on the computer to see the issue. I will never buy a Kia again. There should be a recall on this 2016 Kia Optima.

  23. Engine, May 18, 2024

    I was on [XXX] and had already traveled over 300 miles with no previous issues at all on the trip. I had just stopped at a gas station and there were no odd smells or sounds. There also no warning light on the dash. Suddenly, I lost all power and at the same time my engine light and oil light came on. Before I could make it from the inside lane across two lanes of 70-80 mph traffic at a rapidly declining speed, my motor started knocking. My engine is seized up because of lack of oil when I just had an oil change less than 1,000 miles ago. I'm lucky [XXX] traffic didn't run me over before I could get out of the way. How is this same issue not a recall yet when people are at risk. Had someone not been paying attention to people In front of them my lack of ability to drive my car could have caused a horrible accident!
