We also loved our 2009. It was at the point of needing ~$1.5K in work and since it only had a backup camera, we decided to upgrade to a current model with all the safety features. What I don't like:
1. Scratches all over the car. Clearly a sub-par paint job.
2. Blind spot warning is visual only and no way to get an audible warning.
3. Will not recognize when you are in reverse and a person walks behind your car. Yes, I know I really need to look and not rely on technology. Lexus says this is normal.
4. The redundant joystick that takes away from any additional small areas on the console for your stuff. It's hard enough to remember how to access what I don't access on a regular basis so give me that OR the joystick...I don't need both.
5. Coffee cupholder area sucks. Give me a place, with easy access, to stow my kleenex.
6. Whoever designed the seats (a former airline seat designer ) has a special place in h**l. They are 1" thinner than our 2009 and have 3 seams instead of the 'usual 2'. As a result, due to my ongoing hip bursitis, I am unable to drive this car w/o excruciating pain. Unfortunately, the hip pain manifested itself a few weeks after we bought the car . DH also finds the seats not as comfortable as the 2009 or our 2016 Acura RDX. Neither of us are obese, however, the seats were designed for a size 2 person weighing 120 lbs. Obviously this issue is not the fault of Lexus, but if I have to live with the hip pain (other medical issues are causing it and I may have to live with a certain level of pain), we'll be getting rid of the car.
I have never hated a car as much as this one. You asked .
7. The seat assignment and key don't talk to each other. By that I mean we have to press the assigned seat position number in order for the seat to adjust to our input preferences. In my Acura, the system automatically adjusts to the driver's assigned position; no pressing the appropriate button is necessary.
