couple of things to try first , is the trans fluid at correct level ? when was the fluid last replaced ? have the OBD codes read as may tell you what the problem is , if you done all this i'd go to a repar shop for advice

have the OBD codes read as this will tell you which sensor/switch is at fault , there a many things that it could be

Are you idling or is it doing 10 PSI driving it? If it has many miles on it it could be just getting worn out and that would be low oil pressure at idle when hot.

Sounds like you have one or more spark plug wires that may have gone bad or your ignition suppressor has failed. Is this high mileage vehicle? You may also have a loose ground in the circuit. I assume all its quiet when engine is not running?

Hard to turn, is a failed steering rack from not changing the fluid every 3 years

Yes the air bag computer retains fault codes for about 100 cycles without a fault present and resets every time it or a new one is detected. clearing the codes starts the system fresh.

Hi, viewer. The symbol that you saw on your dash is the traction control warning lamp. Well there are many possible faults, the best way to determine is to have it checked by a scan tool. You just did the right step checking out your tire pressures. Might as well check your brake fluid and brake light functions. Does your traction light come and go for some time? Try observing if this light come on when you make turns on steering, or when braking, or when driviong on rough road. Your observations can help slim down the possibilities. Okay?
Drive safely and goodluck. : )

{: ) These triangles you saw is for the Stabilitrak (traction control) indicators. Normally these lights should be off after the engine has started, unless you disable it by pressing the stabilitrak button. Sometimes it lights up automatically when driving under certain road conditions, and will turn off later when normal conditions resume. A wrench beside the triangle indicates a fault is detected on thge traction system and it requires servicing.
What you can try, stop the vehicle, turn ignition off for a few seconds to reset the system, and then restart the vehicle. If the lights wont go off, then tghe vehicle really needed to be checked right away.

check for a bad earth in the system . Possibly the earth strap on the motor or dirty battery terminals . IF the temp gauge will not work (bad earth ) and the ac stops working ( cabin air temp reaches setting) or the circuit has an earth problem switching off the ac. Check all wires for broken , not connected properly and check each earth point for clean and tight.

do the brake lights work ?

Clean the throttle body, front and back sides. Disconnect the battery for about 30 minutes while doing the cleaning. This will reset the computer and allow a relearn to the newly cleaned throttle body.

should be marked (CSTY) on your fuse block.

All dash lights should light with the key on/engine off ALL dash lights should go out when the engine is running If you have ANY Light lite,you have a possible system failure & check for codes,diagnose them,component test & resolve You can google your codes or Stabilitrac & read up Read your owners manual

When I had the same thing happen on my 2010 Equinox- One of the ABS sensors had a spot on the wiring that had rubbed thru and one of the wires was shorting. The sensor needed replacing- Check all your ABS sensors and wiring. The Stabilitrack monitors the wheel speed through the ABS sensors- therefore if they are not working properly then it will not work properly. (My ABS light was NOT on in this issue)
