I was just driving on the highway when all of a sudden the "Check Engine" light and orange "Traction control" light came on.

I pulled over and restarted the car but is still on.

Anyone know what the issue could be? Last thing I had done to the car was swap out aftermarket wheels.

 

Search for "carbon build up" and see if those symptoms are at all similar to yours. Did your car stall out or idle rough?

 

There are literally at least a few hundred reasons for those lights to come on, ranging from leaving your gas cap loose to something catastrophic. Check your codes to at least have some place to start, until then it's meaningless guessing.

No, actually I ended up driving it home 30mins away and been driving it short distance this past week, no issue.

I will go to the AutoZone and have it check out and get the error codes before taking it to Lexus.

 

Just went to Auto Zone to get car check and twice it came back with "no code"

Don't think is engine issue... Went n pump air into all 4 tires and still getting same "Check System" light with traction blinking for a min then stays on

The manual says " Indicate a malfunction in tire pressure reading"

Sorry if I posted Check engine light is check system dunno if similar

Anyone know a fix without going to dealer.. I have been driving around n seem no prob but just want to get the lights off

 

Can you post a picture of your dash so we can see exactly what is showing up?

I got phantom CELs and T/C lights and I cured that after some reading up on CL here and seeing there's a problem with the factory gas cap not sealing the system well after a # of years. I purchased a new $6 Stant gas cap from Walmart and I have NEVER seen the CELs or T/C lights since.

 

easy... either your aftermarket wheels don't have tire pressure sensors or they do but you haven't had them programmed yet to be read. your system is now searching for tire pressure readings and isn't reading any since the aftermarket wheels have been installed.

 

My money is on the TPMS tire light, a red exclamation point, and "Check System" in the display.

This.

 

I have the same check system reading and (_!_) symbol on my dash that just popped up two days ago and I still have stock wheels. I have not touched the tires or wheels since buying the car 2+ months ago. Would be interested to see how you fix your problem as maybe it will help me fix mine.

Veach, in your case, I would check that you didn't accidentally change to the alternate set of tire sensors -- controls are the ones that look like this < O > to the left of the steering wheel.

If that isn't it, one of your TPMS sensors may have died. They have non-replaceable lithium batteries that should last about 10 years, but it's not inconceivable that one may have gone early.
