My Suburban is a 2016 and had approx. 65000- 70,000 KM.on the vehicle. (just over the bumper to bumper warranty) I was informed all 4 shocks were leaking and they were not covered under warranty. The offer to replace them was given to me but at an unreasonable cost even at a discounted price. I believe this is a manufactures problem of defective equipment or production and I don't feel I should have to pay for a manufactures problem. If you or GM change their minds and would like to consider replacing these for no charge please get back to me. Regards Don
