I was driving on a freeway (4 lane - 65 mph speed limit) on the afternoon of 2/3/2007 with my cruise control set to 65 mph. I noticed that I was speeding up, and within a short time, my speed had climbed to about 90 mph. At first, I thought this was a malfunction of my speed control, but after touching the brake and turning the speed control off, it continued to go about 90 mph. At this time, I noticed an exit coming up in about 1 mile - so I kept touching the break to keep the speed about 75-80 and when I approached the exit, shut off the car and coasted to the top of the ramp. With the car safely stopped, I was able to get the car towed to a service station, where the mechanic pulled off the air filter assembly going into what I think is a throttle chamber and found a large piece of ice holding either the choke or throttle causing the problem. It is important to note that the temperatures that day were very cold - about 10 degrees F. below zero. After removing the ice and cleaning out the chamber with silicon, and allowing it to warm up for about 15 minutes - everything was okay. I should note that I had taken the vehicle into the local Mazda dealer about a month earlier because I noticed the throttle was sticking - they serviced it and it seemed to be okay, until the incident on 2/3/07. When I called the Mazda dealership, they told me that there was a safety recall on the throttle assembly, but they showed this part had been replaced already. I am concerned that ice can build up in this area and the same thing will happen again, whenever it is cold out. I haven't seen another similar complaint, but thought it would be a good idea to document this - this could have easily caused a major accident.

While driving 60 mph or more the vehicle accelerated up to 110 mph for no known reason, the consumer stated, she attempted to stop the vehicle by applying the brake, which failed to slow down or stop the vehicle. The consumer then placed the vehicle into neutral, which caused the vehicle to fish tail severely. The consumer shifted the vehicle back into drive, a little while later she shifted the vehicle into parked, which caused the vehicle to come to a complete stop. The vehicle was towed to the dealer. The dealer inspected the vehicle and could not find anything wrong.
