Strange how this came up at the top, I had exact same issue this weekend! Failed to rotate tires because ran out of time (had evening errands).

I had this 2-ton jack for a while and used to lift the X5 on the side a few times. This time, tried using that point right under the engine (see earlier pictures).
That was because I needed to place one side on stands (distrust hydraulic jacks, and also needed to use the same jack for rear wheels).

Because the 2-ton jack arm is too short, it could not lift the vehicle high enough for front tires to clear the ground. So, I placed a block of wood between the jack and the lift point and started to lift. Guess what happened? The jack fluid squirted out on me!

Yes, it could be blamed on simple physics, because due to the wood block, a lot of weight was placed on the jack arm at the very beginning when it is still folded low. Yet, you would think it could lift 2 tons right off the bet as advertised.

Regardless, I trust hydraulic jacks even less now..

Going to be replacing the 2-ton jack with 4-ton one this week.

That is a jack failure, not a design failure.
