i was driving fine w/o any warning lights. then i came outside like 3hrs later, all 3 different lights came on.

check VSC, check engine light, and the light(looks similiar to the button to the left of the power button)..kinda look like a car w/ 2 zig zag .

what should i do? seems to drive normal.

do dealers check for free or cost me?

 

yes dealers will check it for free.. under warranty isn't it? i would go and have them take a look at it... but the vsc and the car with swiggley's.... you sure you didn't do the pedal dance? and when you turn off your car and turn it back on... is there still a problem?

 

it has only 8.3k miles..still under warranty. i didnt do anything except driving normal...no dancing.

i turn off 2 times, and turn back on...still the same warnings...so odd.

 

Check engine could come on if you don't tighten the gas cap properly, but I don't think so for VSC and Trac. Call the dealer.

 

Traction control is disabled when the check engine light comes on, so yes, a loose gas cap could cause it.

 

Yep same thing happened to me but since the closest lexus dealer is 2hrs away i just disconnected the battery and it reset itself and thats it you just have to reset everything

 

You shouldn't need to disconnect the battery. Check the gas cap and drive it for a bit. The check is on a timer, so at some point (after 24 hours to be safe), it should reset. If it doesn't take it to the dealer.

 

i tighten the cap 2 days ago, and those warning lights are still on. very strange!

 

You have a code stored in the OBDII, get to the dealer if you don't want to dissconnect the negative battery terminal for 15 minutes. You may have a bad gas cap as stated. You will be safe to drive, just no stability control which is not the end of the world if you don't drive like a madman in a snowstorm (LOL).

 

reset the ECU. If they still are on then take it to the dealer.

 

gonna take it in to the dealer soon.

guess what? it's snowing here in the dc area..4" expected.

how will these warning lights affect my AWD performance?

 

I had the same issue a while ago. I knew I always tighten my gas cap well, so I took it to the dealer and it turned out my car was running lean on bank 3. I have a 350 so when the traction control light was on, I believe I lost VDIM because I didn't feel the Brake Assist in action. I'm not sure if you'll lose VSC on yours. You will definitely feel the difference if you don't have the electronic nannies.

Was the cap loose? If not, the light was probably from an unrelated condition. Get the code read.

 

yes, the cap was loose. tighten it....waited a few days.

the service rep i called the 1st time was right...it did fix itself after a few days.

 

Same thing happened to me 2 months ago. It didnt fix it self right away after I re-tighted the gas cap, called the dealer, then a day later the light went off on its own. So its all good...
