My new nissan has a dash light that comes on when the air pressure gets low in a tire. Well, it came on and I was putting air in just like I have done for 38 years when the end of the valve stem broke off. It is aluminum and where the threads were cut into it for the cap, it had the thickness of a coke can. No problem, $10-$12 for a new valve stem. Nope, $116 for a new valve stem, it is part of the sensor and will not pass insection without a new one. Just a heads up to be careful. The guy at the tire store said they are getting a ton of these. Brilliant marketing tho.
