Optima

My car is consuming major oil. I am having to put at minimum 3 to 4 quarts of oil every 3 days. I am having major loss of power. My car has oil fouled far too many spark plugs. In the last 3 months, I have had to replace the spark plugs three separate times. Within the last 3 weeks I have replaced the following: 1. Ignition Coils 2. Valve Cover Gasket 3. PCV Valve 4. 2 separate sets of spark plugs and 1 singular spark plug for Cylinder #4. My car is having a major oil consumption problem and the performance has been severely affected.

Power train; shift lock specifically: Had to use the release control more than once. While driving when it happens, I feel a surge/ decline in acceleration(something I requested be checked a year and a half ago, but Kia said they could not recreate my description).continues to drive but sluggish to accelerate. Once I put into "park" I cannot get it out of park except to use release. It did reset(?) when I turned the car off. Suspension; first few months of owning the car I periodically heard a creak in rear suspension here and there when backing out of driveway/gutter slope. Have noticed an increased creaking and more bounce while driving over time but have not even owned car more than 2 years.
