Hi, We've brought a 2009 Tarago. My wife just told me that the cruise control seems to have problem. For example, when she turned on the cruise control and set the speed at 80km/hr. It worked fine until the car went down a slope in Melbourne East Link Tunnel (which is just a small slope). The car kept accelerating and when she noted that, the car was driving at 100km/hr inside a 80km/hr limit tunnel. She was scared. Similar issues have happened several times in different places. We have been driving Toyota for more than 10 years and this is my third Toyota car. This problem didn't happen in my previous Carmy Sportivo. I am not sure if this is normal or not, but I do think it's very dangerous. Because of this, she need to keep her eye on the speedometer when using the cruise control, which is quite disappointed. Besides, the speedometer doesn't display speed correctly. For example, it displays 100km/hr, but my actual speed is about 90km/hr. I told the dealer when I had my first service. They said it was normal and they wouldn't fix it because the different was less than 10%. There are two problem seems to cause safety issue: 1) The speedometer is not accurate. 2) The cruise control fails to control car speed. Do you have similar issues? Thanks.
