Topic starter

My Kia Optima 2016 LX turbo has 61k miles on it and shakes in the morning when I accelerate slowly. At high speeds, it performs flawlessly. There is no error code on the ECU. any suggestions or anyone who has dealt with a similar problem.

Does it also happen when you coast at lower speeds?

I haven't tried yet. I will do that and let you know about it.

so I tried costing with the following scenarios

1. if the car is neutral then it doesn't shake 

2. if the car is in shift then it shakes on low rpm 

3. if the car is in shift and engine is warm enough and RPM are more than 1.5 then it also does not shakes

When was the last time you changed the ATF?
