Dodge caliber tyre pressure light keeps flashing but tyre pressure ok

You'll need to do a little bit of detective work. OK, When exactly does it "squeak"? Is it a short, single squeak, a stretched out long squeak or does it repeat a few times as it happens? Is it when your driving in a straight line and you hit a pot hole? Is it as you brake firmly? Is it when you take a corner at a reasonable speed? Is it when your turning the steering to full left or right?
Check your tyre pressures are all correct. Sometimes a slightly soft tyre can cause odd noises. Assuming yours has 215/60/R17 H 96 size fitted they should all be set to 32psi.

Sounds like your oil pump is failing and there is not enough pressure at low revs. When was the last time you changed the oil and oil filter? It is the right weight oil?

It is a known issue

Do the 4 way flashers flash the lights?If they do flash it may be the signal light switch or power to it.

DODGE CALIBER 2007 2009 SERVICE REPAIR MANUAL
I suggest you get one of those manuals people get nowadays to do it yourself.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from.

Ellen, check oil level immediately and top up if needed, if was low and light goes out, that was the problem and count yourself lucky that the engine did not blow. If oil level OK, take it into a shop for diagnoses before some thing bad happens to engine which could cost thousands of dollars.

if it does it when you shut it off, might be stopped up plug that allows air pressure to release to keep pressure from building up

check the pressure in your tyres .may need topped up.

Check for fault codes --- blocked cat converter---- low pressure in tyres.---blocked air filter. low fuel manifold pressure--- auto not shifting to overdrive---- ambient air temp sensor faulty---are just some reasons for poor economy

Check the bulb (s) first, then check the fuse. If all is ok check the switch (s) in the door jam. (You didn't say if it was one door or all doors)
