| Description of the problem | I am assuming you have seen the article about steve wozniak complaining about his cruise control on his toyota prius. It is an issue of using cruise control with the sonar activated to slow the car down to maintain a safe distance between the car in front of you. When the car in front moved out of your lane, your car takes off like a rocket to regain the programmed speed. I have a toyota sienna mini van that does the same thing he described. When i complain to the dealer they tell me it works as designed. I ask them if they want to drive their kids around on the interstates using the cruise control with the sonar activated or pay my speeding ticket when i get pulled over when it does this. After accelerating at such a high speed the braking mechanism kicks in to slow the car down. So you know you have gone above the speed you set the cruise control. A car shouldn't take off like a rocket and cause you to speed when the car in front of you moves out of your lane. It also does this with the sonar off and hitting the "resume speed" switch on the cruise. I have not had an accident with this issue, but it sure is scary when it does this. As a result, i don't use my cruise control very often and if i do, usually kick it off by tapping the brake when the sonar slows the car down so it doesn't take off like a rocket. I am sure it is a programming issue but it sure isn't safe or comforting the way it currently works. |
