I was prompted to add air to my front tire due to the low tire pressure light coming on. After I added air I attempted to put the tire valve cap back on the wheel and it began forcefully blowing out air. I attempted again to secure the cap and the valve stem sensor came out of the valve stem completely. This is a huge safety risk, and I am now concerned this could happen again. I urge Volvo to honor the replacement of their faulty tire stem valves immediately.
