On two separate occasions, while driving car on highway at high speed, the car has gone into a special shutdown mode, where a turtle icon lights up on the dash and the car begins to shut itself down rapidly, limiting maximum speed of vehicle to 35mph. There is no warning or advanced alert. Suddenly the car reduces speed and feels like it is dead, and the systems begin to alert you that they are going into a reduced function mode. This was extremely scary thing to happen at highway speeds with flowing traffic. I had to crawl to side of rose at very low speeds. I could have been injured. I took the car to dealer for service and they said it was a software issue. A few months after, this happened yet again, also while at highway speeds. I have read that others are having similar issues with the Volvo XC90 model. This is so dangerous and the dealerships are writing it off as a software matter! It is extremely dangerous.
