just remember any jack can fail, a cheep POS scissor jack can be just as bad. the nut threads strip out and you have nothing holding your car up. even if you get an OEM one from a wrecking yard it may not have been meant for a car as heavy as yours.
that's why you never get under the car with just it holding your car up.
also, my HF POS aluminum jack still works great after 6 years and lots of use
