Hood latch and cable malfunction in that the hood wouldn't close and warning light and buzzer continuously beeped. Woburn Toyota in Woburn, MA said it was due to overuse and not a defect and not a safety issue! Not so. Hood not opened more than other vehicles I have had without such a problem. Other Lexus owners have posted similar complaints, too.

The moonroof suddenly shattered (it sounded like an explosion) while I was driving on the freeway in 70 degree weather. Initially I had no idea what it was but realized subsequently that I was shedding glass shards behind me. There were no overpasses where someone could have dropped something, I did not see a rock or other projectile, and - when I parked the car - I found nothing that from outside seemed to have struck it and/or stayed behind in the cavity.

The pcs (pre collision system) warning icon flashed in the display indicating that the pcs was temporarily unavailable. The vehicle was being driven on a highway. Pulled over to look in the owners manual only to find that the manual told me to stop. We proceeded to return home without experiencing any adverse handling. I really don't feel safe driving the car not knowing if the pcs system will fail.

Door locks do not lock via key fob on 3 doors. Lexus wants $800 per door to fix. Have manually locked car for one year; now cannot manually lock door as the manual lock no longer locks. This is safety issue as car remains unlocked at all times.
