 I fell in love with the body of the car, but the primary reason of purchase was the great financing Toyota offered me. It was a no brainer so I purchased the 2018 Camry XSE V6 back in Jan. I drove the car mainly in eco mode, but every now and then, when I felt like having a lil fun, Id put it in sport and barely  give it a little gas and it had amazing torque. I recently took the car in for the 1st maintenance and everything changed after that! I can no longer drive the car in eco, unless Im in traffic and don't need to drive past 20 mph. Normal mode now feels like how the old eco drove and sport mode is a complete joke. It has ZERO torque now. I took the car back and talked to 3 different supervisors who looked at me like I was crazy saying all we did was do a tire rotation and top off your fluids. I had their lead tech drive my car who did not notice anything and "ran some tests". He came back and said nothing is showing up and there is nothing wrong with your car. I told the supervisor to have his tech drive a new car and then drive mine again. He did and still did not admit to any difference. When he stepped on gas in sport mode with the new car, I pointed out to him thats the torque that my car now lacks. In the end, he concluded it was the gasoline I was using...I use the same gas from the same station for years so this was highly unlikely to be the issue in my mind. So far, I have went through 2 more tanks of gas and still no improvements, that very clearly is not the issue here. I am furious that I had zero issues with acceleration before taking it to Toyota and am now left with a slow car that does not change gears properly. I hear the torque but don't feel it, I have even floored it and it did nothing!  The other issue I have is seatbelt in the back, when the arm rest goes down in the back, it throws off the seatbelt sensors and everyone in the car has to unbuckle and re buckle to turn the alarm off. I am very dissapointed since this is the first car I have ever purchased and I will never buy a Toyota ever again!
