OK, I took a lot of crap from AveoSS for my screen name, but here is another reason why. Like I said before I have had tons of problems with the Aveo and different sensors and CELs etc and hard times from the dealership to fix it. Currently I am living with a CEL. Well now on the way to work my TPMS starts flashing for a minute, then stays lit. OK, get to work and park it. After work, no light, drive for ~25 miles, same thing, light flashes, then stays lit. This has been the same thing for the past four days. So I find myself googling this and low and behold here I am, at this thread. My dash looks like a christmas tree with all of the lights. I am told this is a malfunction in the system and of course it is out of warranty, so this light will stay on too. So basically I am stuck with this car until it dies because I can't sell it or trade it with all the lights, can't pass inspection with a CEL, don't want to pay a dealerships hundreds or even thousands of dollars to fix a car I will never get my money back from.
Thought I would share my experience for others in case they have the same problem.
