The inverter ( a very expensive electrical component) on my 2006 toyota highlander hybrid failed resulting in a complete loss of power on the highway. The car was towed to dealer. It took a week to diagnose and repair. Repair was covered under the extended warranty that applies to hybrid components. I have asked, but toyota can/will not tell me how often this type of failure has occurred; the internet has stories from others who experienced this type of failure. Complete loss of power on the highway is clearly a safety issue. With toyota's reputation, I can't help but wonder if this is an issue that they don't want discussed.

The toyota dealership where I bought my 2006 highlander hybrid new installed a car alarm at the time of purchase. While going down the road the left hand passenger "door ajar" alarm will begin going off. This is very disturbing and dangerous at night because it will cause the dome lights to flash on and off as well as the dinging of the bell. This typically happens when hitting pot holes - but I do not always feel any bump. I have had the car into the dealership several times for this problem. They finally traced it to a cause of "the knock sensor for the alarm is tied to the ground in the door ajar sensor", they said that the connection was loose. The first time they replaced the alarm, the second and third, and ... Times they said the wire was loose. The last time I advised them to change where the alarm knock sensor was grounded and they said that they solved the problem with a better connection. Granted the problem does not happen much anymore, but it still continues. On a recent trip from san diego to corpus christie the alarm went off for about 15 minutes on the second morning of our trip. It typically happens in what seems to me as cooler damper weather. Again, I feel this is a safety concern that has been largely ignored by the dealership (toyota of poway in poway, ca) the last time, they told me that the vehicle was out of warranty... I have not contacted them after this last incident in december on our trip, then again last weekend (saturday night) when driving home from a casino - about 15 dings and associated flashing lights over a few seconds.
We have a 2006 toyota highlander hybrid. There are a number of minor but annoying problems: 1) battery dead in morning 4 or 5 times for no apparent reason. 2) after turning off engine and opening door, buzzer occasionally goes off for no apparent reason. 3) some radio stations pick up a lot of static when brake pedal is pushed. 4) dvd carousel player picks up errors when attempting to play disks four or five. Wrote a letter to toyota in 2007 regarding some of these issues but got no response. These problems could be related to the electronic issues we have recently been hearing about.
