My Volt told me by email its right rear tire had only 22 lb pressure this morning. I topped it up and brought it to the tire shop where they took a big screw out of it and repaired it. Is that ever a useful feature especially for a car without a spare. My car is an LT, a base Volt but the standard equipment is amazing. One year old and 12,000 miles by the end of the month. No problems.

I love the TPMS feature as well. I keep my tire pressure permanently displayed on my dash.

I agree. I really like the TPMS feature and it is my mainstay display. Last month, I also had a screw in a tire and was early enough to have no pressure change. I found it when washing. No worries since it was time for a rotation. Our mountain curves are rough on tires and all kinds of things slosh out of trucks.

My 2007 Nissan Frontier Nismo only has a low pressure warning light that is notoriously on permanently for most trucks. I am thinking of investing in a new system that gives a read on all four. But for now it is a black tape on the dash repair or just live with it.

My Volt to and from work is a great part of the day...and I am lucky enough to truly love my job.

Suggest use Driver Information Center to monitor tire pressures continually-just select it and leave it in the display as you drive.

Forgive me, but I thought most newer cars (2000+) had TPMS on them. I keep the TPMS screen up on my DIC as well, but I was expecting any car from this year would have this feature standard.

Just so you know, if you’re driving along and get a tire pressure problem, the TPMS warning light will flash on the DIC to let you know, even if your display is set to something else. I've had it happen to me in my 2012 Volt. As the manual says:

"The TPMS warning light alerts you to a significant loss in pressure of one of the vehicle's tires. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading Information label. The warning light will remain on until the tire pressure is corrected.

The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This may be an early indicator that the tire pressures are getting low and the tires need to be inflated to the proper pressure."

A nail puncture is typically a slow leak, like a pound or two a day. So having the air pressure displayed on the DIC is preventive. You can detect a leak well in advance of when it hits the 28 psi error message threshold. I run my Michelin Primacy MXV4's at 40, and it bugs me to see a number less than that on the DIC. My air compressor sits in the garage just in front of the Volt. In about 30 seconds I can top off a low tire.

Tire pressure is not one of the things I display continuously. The car warns if there is a low tire as the OP states.

IIRC VW went from the sensors to the rotation differential method my old Buick has.

Yes. I agree. The fact that it tells you which tire needs attention is great too. My friend has a new Volvo that just alerts him that one of his tires is low, but he needs to actually check to see which one it is.

Your friend should check his DIC system. I believe that Volvo provides a screen that shows you the pressure of each tire, it just doesn't pop it up when one is low. Volvo also uses a temperature adjusted system which is better than most. On a cold day many systems will report your tire low because pressure goes down with temperature, and it can be annoying to have to constantly fill your tires in the winter as the temp fluctuates. The Volvo system compensates for that.
