My daughter bought a used 2019 Optima from a local Toyota dealer. They gave her two free oil changes and then the third they charged her 70.00. I told her on the fourth I would start taking care of her car for her. Very disappointed with Toyota. The bottom cover only had three bolts in it. It may not be Toyota's fault but they could have a least let her know this. After looking I saw they used the cheapest STP filter available and charged her 12.00 dollars. The drain plug was stripped and over-tightened to the point the plug was twisted. I had a very hard time getting it out and I thought the oil pan threads may be stripped. Finally, got the plug out and went to NAPA and bought a new one. Pan threads were OK!! Next, the oil filter must have been put on with an air-impact wrench (Like the drain plug). Since it was an STP filter my filter cup for a KIA filter would not work. Spent a half hour getting this burger off They also said on her paperwork that the air and cabin filters were inspected .... LOL The cabin filter had leafs from last fall in it. The air filter was filthy. Off to NAPA for filters. She also asked for full synthetic and got the blend. At least they didn't charge her for full synthetic.
