Koup with 1000 miles, I searched but never found my exact issue so perhaps someone can give me a clue.

5-6 times in the last two weeks after about 1 hour of driving I have had the ((!)) low pressure symbol flash for about 1 min, then go solid and go out or go out upon restarting the car. I have checked the pressure cold and it was 32 psi on the dot. Thinking it was getting too high (don't know the upper limit) I dropped the pressure to 30 cold but still had the issue recur.

Last night the light flashed and went solid a mile from home so when I pulled in, I checked the pressure hot and all were 32-33 psi so it's not an overinflation issue AFAIK.

I have read it can be caused by RF interferance but really it's wierd that it's happening after about 45-50 mins of my commute, not in a specific spot.

I reinflated to 32 psi cold today since I don't think it's pressure related.

Anyone have a good clue? The TPMS light has never come on.

I had the same thing happen in conjunction with a transmission problem last week. It went out on its own and air pressure was fine. It might be a connection problem on the computer. Might want to have the dealer check it out. Read my thread "trouble codes - weird!" where I went into some detail about this problem. I think this problem may be in some way related.

I read your thread when I was searching the forums. I'll prob take it in to have it checked out.

...and I'll read the frippin' manual in the meantime.

Well according to the '11 manual, the blinking of the ((!)) symbol for a minute followed by illuminating steady is a system problem. I never get the [TPMS] warning light though. I'll see if it lights up when I go to start the car.

I drive far and fast and want to be able to trust the indicator if a tire goes flat. I've driven on flat rears unnoticed on a FWD car before.

There is no [TPMS] idiot light on the SX Koup that I could find, just the ((!)) symbol, so I must deduce that the blinking is indeed a system problem. It did not happen on my 50 mile commute in this afternoon. <shrugs>

does it blink and after a while just stay on?

if yes then one of ur sensors is either broken or just not responding. u can take it to the dealer and get it checked out

Yes, blinks for a minute then comes on solid for a while and goes away. Hasn't happened in two days now. Next dealer visit I'll mention it.

Been fine for a week, light came on today but in the sunshine I never saw it blink. Thought it was crying "Wolf!" again after I stopped for gas.

Went out after dinner and the RR tire was almost flat. lol. I guess it wasn't lying tonight.

I did that last weekend, it was fine at 60 psi but I bumped it up to 65 as I'll prob forget to check it for a year. I keep a duffel bag in the trunk with a compressor, tire plugs & emerg stuff in case.

Pain that it's stored with the valve stem down.
