“We were driving on the highway from dallas to houston and all of the sudden, we heard and explosion. At first we thought that something hit our truck, but when we opened the sunroof cover it was completely shattered. Some pieces hit the car behind us, but no one was hurt. Luckily the interior cover was closed.”

“About a year after owning my magnetic gray 4RUNNER I started noticing flaws on my hood and roof of the vehicle almost like the clear coat was bubbling up. I expressed my concern to the dealership during a routine visit and the supervisor said it will be noted in the vehicles record.

Nothing hit the window, and I hadn't hit a pothole or any bump in the road, there also was no extreme change in temperatures ' it just exploded into many pieces including small shards of glass. The glass went all over the inside of my car including both front and back seats and floorboards. The entire window exploded so that there was no window left in the opening. I believe it was faulty glass. …”

Since I was driving, I was not able to do anything with either my phone or my navigation system. It acted as it if was just trying to reconnect to my phone when it was actually turning off and rebooting as if I was just starting the car .the third time it happened, I was making a left hand turn on to a very busy four lane road when in mid turn, it felt like I had lost power steering. …”

“Toyota entune (iphone app) will not pair with your phone or disconnects during use because app does not maintain the user's login credentials. The behavior of the connectivity between the vehicle's entertainment system and phone is difficult to predict, sometimes the system won't work without the phone's app running and other times it will - sometimes it won't work even when the app is running. Often, when the entertainment system fails to connect it stops functioning and pops up messages that require user input while driving. …”
