When decelerating, particularly on hills or into corners, there is an intermittent surge that occurs after the brake pedal has been depressed. It feels as though there is a release of the braking action, this is unsettling as if you are starting to approach a vehicle or pedestrian, this sudden "delay" of braking could result in contact with other objects. We have changed our driving behavior as a result of this. We reported this behavior at 5000 miles and there was not a solution until last year. We were not notified of this, and our vehicle is now out of warranty. Toyota has released as of last year a TSB related to programming and we are going to pay out of pocket $300 this week to get that TSB applied. This doesn't seem fair to consumers. . Read more...
The entune 3. 0 system governs navigation, calls etc. The system on my car has been replaced 4 times and still does not work. This is a life safety issue as the system grabs phone calls while driving without being able to answer. It also makes it frequently impossible to use hands free on the phone as it grabs calls. In order to avoid it grabbing calls I have to disable bluetooth on my phone which then causes my phone to not work in handsfree mode (ok google etc. ) furthermore the backup camera does not always work. Finally, a Toyota service manager told me in his oppinion 25% of the entune units are "bricked," non functional and need to be replaced. Toyota has fired according to him panasonic as the supplier and now has a new provider.
