The Car has been to the dealer several times for a transmission judder update under TSB: TRA 083 and Recently TSB TRA 098 - Both Times they have done a Anti-Judder Logic Improvement. The Car still Judders and Its a big safety concern. Many times I will go to pull out into oncoming traffic and the judder can be so bad the car wont take off. This happens several times a month. I have complained about this since I bought the car and primarily they blamed it on being a Dual clutch transmission. Years later they have now 2 TSB and the issue is not solving the problem. The imparticular dealer that I use has told me they have never had to change out the clutch on this car and dont have the tools. They also said the way that kia uses software to monitor the judder never warrants a change in the dual clutch. I believe that Kia should take responsibility and install their new updated transmission into this car.

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.

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.

WHEN ACCELERATING FROM A COMPLETE STOP, THE ENGINE SHUDDERS & HESITATES. I MUST ALLOW EXTRA TIME & SPACE FOR ONCOMING TRAFFIC, WHEN PULLING OUT INTO AN INTERSECTION. THIS IS AN ONGOING PROBLEM. KIA SAYS THE VEHICLE IS PERFORMING AS IT WAS DESIGNED TO. I THINK A RECALL SHOULD BE CONSIDERED, AS I HAVE SEEN NUMEROUS, SIMILAR COMPLAINTS ON VARIOUS WEBSITES REGARDING THIS PROBLEM.
