What owners wrote

..... On at least 5 seperate occasions our 2021 mazda cx5 SUV accelerated to a high rate of speed (on it's own). It has done it to my wife and I both. I contacted two different mazda service centers and was advised they have no knowledge of this and that there are no open recalls or tsb's and as intermittent as it is it would be almost impossible to duplicate. On july 18th the car accelerated (on its own) again but this time it drove my wife into a tree at aprox. 35/40 MPH breaking her ribs.
