NHTSA Complaint #11543155 — 2017 KIA OPTIMA

In the last year, my car has been in the shop countless times. I have had my knock sensor replaced and fixed multiple times. There is a significant lag when taking off from a complete stop, and there have been times that I cannot exceed more than 60 MPH. I have had my car serviced the exact way it states in the owner's manual without fail and still cannot find a cause for why my car is experiencing all of these issues. To get the motor to accelerate is nearly impossible 90% of the time. There is currently a recall on some other 2017 Kia Optimas for the Knock Sensor but there is not one on mine, even though mine has been replaced and fixed several times.
