Electrical Jack problems of the 2015 Audi Q7

Audi factory car jack failure. My vehicle was stationary in my driveway. I was using the factory provides car jack to left the right rear wheel in order to replace a flat. I used the jack as instructed. However, as a precaution, I placed an a jackstand under the car as an addition. With less than a second after removing my hand, the factory jack snapped and broke. Fortunately I placed the jackstand underneath my car. I nearly avoided serious injury. Had I moved any slower, my hand and body would have been crushed because of the factoru car jack's failure. I looked at the jack and a key component suffered a catastraphic failure, snapping in two. Audi should not provide a jack that cannot support the weight of a SUV. I couldve been seriously injured.
