They indicated that there was sludge in my engine but could never prove or show me anything that they did to document the sludge and trying to blame it on me. This car is a safety hazard as I am aware of mini other Kia optima-??s dad have either caught fire or repaired to have their motors replaced due to the same issues.

Was exiting the freeway, came to a stoplight, and as continuing with driving the check engine light starts blinking and was not able to accelerate, as if it was slipping. Car would not go over around 30 mph until feeling the car not able to accelerate again. I used a code reader and got code P1326, which I had looked up and says it has something to do with a knock sensor detection system. Had bring my car in to get it checked out and was told my car had low oil, about 2 quartz. I do regular oil changes though and had done an oil change a few weeks prior. The shop I went to told me there may be a service campaign for the car. Was told specific years have had engine problems with oil, losing oil although no leaks or signs.

Car lost acceleration while driving

- Killeen, TX, USA

From a stationary position, upon accelerating the car hesitates, vibrates, feels as if it might stall but does not stall. Car, within a second or so will catch and accelerate as it should. Driver is very aware of the vibration hesitation. The passenger can also feel the hesitation. Skipping sensation happens at any stopped location, at an intersection or stop sign etc. I T seems to happen about 75% of the time. Occasionally there will not been a hesitation experience. I have taken it in at least 2 times to dealer service department and was told thy could find nothing to account for the problem and even suggested that I use a higher grade fuel. Fuel milage is great, all other driving aspects of th Kia are perfect.

P1326 engine code came on while driving 60mph on the interstate. Luckily was in far left lane when engine shut off and was safely able to get off freeway to a nearby gas station.

E - C V V T seal seating issue. My 2016 Kia Optima is giving an obd II error code of P0010 "a" camshaft position actuator circuit. This causes reduction in power during acceleration, and elevates engine idle speeds to 1200-1400 RPM. This elevation in engine speed causes the car to try to move forward even when the brakes are pressed in stop and go traffic. In stop and go traffic, this could easily lead to vehicle crashing. This, I believe, should be a part of recall instead of a technical service bulletin from the manufacturer. Hyundai and Kia use same engine, and has a tsb number 15-01-022-1, and Kia has a tsb to change the motor plug and ecvvt cover for it. They are aware of this issue in their car, and it should be a recall. When the car was in motion for me the first time the check engine light came on, I almost hit a car in front of me as the engine does not go back down to idle speeds. This is dangerous.

Was traveling to dallas, Texas from waco, Texas on 10/05/2019. The transmission in my vehicle went out. The vehicle surged erratically multiple times, while the car was slowing down, speed limit was 75mph, with barriers on both sides (no shoulder on either side. Of interstate 35 North) my vehicle got down to about 40mph when we had to coast until I finally found a break in the barriers. Was a very scary situation. They were vehicles obviously driving speed. Limit behind us. I was able to get off the interstate and call road side assistance. They towed the vehicle back to university Kia in waco, Texas. Where it currently sits, awaiting a new transmission. We are terrified to get behind the wheel of this car again. All I am being told is that a new transmission is being ordered at this time.
