Yes, it's standard on all three Aveo models.

Wow, I wonder if my friend's Hyundai Accent has it. Crazy.

 

If it is an 08 or later, then yes it has it. It is the law. A stupid law, but a law nonetheless.

 

just makes after market wheels more of a pain

 

And tire mounting more expensive.
I plan on doing this though:

You can get an aftermarket TPMS installed, but doubt you'll see enough mpg increase to justify the cost.

 

my 07 Acura TSX has one...

 

^It became required on cars sold in and after 2008, that doesn't mean that cars earlier than that couldn't have it.

Just like a few cars had seatbelts before they were mandated, same with airbags.

 

95% of those systems don't even identify which tire has the problem, or what is even happening. It's just an idiot light of "something is severely fubar".

My Mazda had it, was pretty lame. On cold days on cold starts it complained that tire pressure was low, but once it had all warmed up the light went away.

 

the TL comes standard when it started in 2004, so my 2008 TL-S also have that feature.
