The pre-collision has never worked , took it in to toyota and they said it was good and that there was no way to test in real life . but it has not worked since car was new . there have been many times when there was a car very close stopped or moving slow in front of car and i am apparently ready to hit ,but no alarm or signal.
While driving on the freeway with no other vehicles around me the moonroof unexpectedly exploded showering the interior with razor sharp shards of glass which inflicted a splinter. after contacting toyota, i was informed that moonroofs are not covered under warranty i have pictures on my phone of these shards...
