Lexus RX 2004-09 :: 2007 - TRAC / VSC / ABS / Brake Light Comes On Intermediately?
Mar 21, 2015
I have a 2007 RX350 and these lights come on intermittently --> TRAC & VSC LIGHTS ON. ALSO ABS, BRAKE LIGHT. When I turn the car off and on again they would disappear. So I cannot take it to Autozone (For code read) because the problem goes away when car is shut off/on.
I believe it is tied to the front brakes which are new but the steering wheel shakes when braking. I had the rotors turned a year ago and it seemed to have fixed the problem but now the shakes are back and so is the light problem.
This makes me think that there is a loose connection (Wire / connector) around the front brakes.

08 RX350 with ~100K miles. Two weeks ago the Check Engine/TRAC light were on, VSC light blinks, so I tightened the gas cap, and pull the negative and cleared the code. Hoping this is just a gas cap issue.
2 weeks later all those lights are back again, so my mechanic pulled the code and came up with P0128. He told me it should be the problem with the Coolant Temperature Sensor. The water pump, thermostat was replaced last year and coolant level is OK. No issue with coolant temperature and the car drives like normal. My mechanic cleared the code and told me to drive it again until the lights come back and he will pull the code again.
08 RX350 AWD

All of these lights came on for no apparent reason. I check with computer based OBD reader, and I'm getting code P0049 (Turbo/Super Charger Turbine Overspeed). Weird code considering the lack of turbo or super charger on the GX. I cleared the codes, but all came back after a few miles of driving. What code P0049 is pointing to? My truck is 04 GX470 with 74,000 miles.

I checked the air in the tires on my 2008 350 ES with an outside temperature of around 40 degrees. Pressure gage read 25 lbs. I decided to add pressure to bring up to 30 lbs. Subsequently while driving, the Trac & VCS System malfunction warning symbol came on (the picture of a car with wavy lines behind the tires). Of course, the warning symbol of a red triangle with an exclamation symbol in the middle as well as a check engine light also came on.
I figured that the problem was that the combination of cold weather (for Houston) and the added air pressure resulted in the system interpretation of an increased skid or lack of control situation. So I let some air out to where the pressure in each tire is 27 lbs. Then I drove it 5 miles or so at speeds up to 50 mph. Made no difference. Warning symbols still there.

My completely un-modified fully-loaded V6 Camry SE is currently in the shop getting the brake actuator assembly changed after almost a YEAR of these lights randomly coming on. There was no rhyme or reason. I'm a tad OCD so if there was a pattern,I'd have found it. Never came on to where they could test it. Said they could do nothing until they saw them. I took photos, but they acted like they'd never seen it before. Finally, as I was just ready to pass the dealership, they came on. I pulled in and they checked and said the lights came on right when I "was going 4mph, on an angled curve with my foot on the brake!"
And after an hour and a half said I needed to leave the car, gave me a warranty rental, and said they'd call me. I called them to learn it was the actuator assembly that was going to be replaced and one would be overnighted in. So I have a 4-cyl rental without all of my perks, like the moonroof, the heated seats, the automatic rear view mirror, back up camera.....what a difference! I'm spoiled after 19 months of my Camry! Oh, and when I first got it, there was a bad musty odor from the a/c vents every time I turned it on. I bought it with 55 miles on it...they said "all Toyotas do that."
I said this is my 3rd Toyota in a row, and I ah do one in the past. Oh, "brand new Toyotas," they said. My corolla was 6months old when I bought it. After 2 years, I traded it in for a brand new FJ Cruiser, then traded that in 6 years later for this brand new Camry. Nothing! Finally, I get a notice in the mail from Toyota re: a/c condenser pan overfills, not draining, and can cause airbag problem! was that stench water in the pan, seeping in through the vents smelling like a dirty rag not enough of an explanation that something was wrong. We had to wait until it could have been an airbag issue? Yikes! Happy that took care of the problem and my new car smell was back in no time. How it goes with the lights!

My brake lights keeps going off and the stop fuse keeps blowing and when it blows the TRAC light turns on and stay on. I try to change all the brake light bulbs and the 15amp fuse that was blown but it blows again what could it be?

I've got an 01 Tundra with 170k and no trouble. And a 01 Highlander 4 cylinder with 330K and no trouble. We just added a 04 RX330 with 170k on it. It had an impeccable 15 page Lexus dealer history.
That said, I had the check engine, Trac off, and VSC light come on about a month after we bought it. I used my acton scanner cleared it out. Then I noticed the gas cap was loose so I attributed the issue to that.
Yesterday, the lights came back on again. I have not cleared the code this time. My scanner is showing a "P0420 Catalyst Efficiency Below Threshold Bank 1" error. This car has a brand new cat installed by the Lexus dealer about 6 months ago.
I saw the buttons below the dash that say Trac off on them.

I bought my wife a 2005 Gx470 this past weekend. She has only driving it for the past 2 days. (still had gas in the old car, which is now for sale) She called me and said the VSC light off light came on and the Trac light was on. I did some quick searching and couldn't find anything definitive on what or why the lights came on for. She got gas yesterday, but probably only drove about 40 miles. I asked her if she tightened fuel cap until it clicked, she said she thinks...(crazy pregnant woman).
I'm trying to avoid a trip to a dealer on a car I bought 5 days ago. Also, how to reset the codes without a computer? I know my GMC truck, I just unhook the battery for 30mins or so and clears all codes. Hoping Lexus has a cheat too

Got in the car today, first cold day of the year , minus 8C. Start the car and the engine light comes on. Trac locks off too. I went straight to the dealer , they took it in right away. After about a half hour the technician comes up to tell me that the mass airflow sensor is no good. He has ordered a new one. Apparently the new version has a different part number which indicates that it may have been problematic. He cleared the light and it stayed off all day. Part should be here in a couple of days.

SO all three lights came on and wouldn't go away.
Ran a scanner for code and got p0430.
Took it dealership for estimate or fix.
Go figure : code summary: Causes.
Reported fixes or Causes: for code p0430
- catalytic converter has failed.
- Air fuel ratio sensor
- Bank 2 cat converter
- Bank 2 (A/F) ratio sensor
- Oxygen 02 sensor
- downstream Oxygen 02 sensor
- Exhaust pipe
- Mass Air flow sensor
So I am waiting thinking ok let be one of the above causes or fixes that is cheap.

This is happening intermediately, maybe 1 out of every 5 starts.
Using the override I can shift just fine and the lights go away within 2-3 minutes. However, there's obviously something misaligned here. Search revealed potential brake switch issue (my tails and brake lights are fine so no issues there), lockout issue, or a park neutral switch.
So I took the panel apart and I am trying to isolate these potential issues, image attached, what I need to do next? I am more of a visual person so if someone can circle the part I need to disassemble or replace that would be most useful.

So I was under the hood and was checking something out and unplugged the MAF sensor for a bit and put it back. Put everything back to the what it is, but now I have TRAC OFF on my display and Check Engine Light.

I was driving on the freeway and the trac and engine lights came on.. Noticed that I am no longer getting the Eco light when coasting. Ran the codes and it's P0157 and C1201. I have recently changed tires, not sure what other reason can cause the lights.

2006 gs 300. Been driving car around and the 3 lights came on which are vsc, Trac and check engine light all at the same time. Replaced the 2 front O2 sensors but the light keeps coming on and off. When I drive the car the car hesitates to go over 25 mph.

I had a check vsc, engine light, and trac light come on... I got the code checked and it returned P0300 only. That was three days ago (5 totals days of the lights being on) and today I start my car up, and all the lights are off.
I've only had my 2007 ES 350 for 5 months. I bought it used with 48k miles on it. I'd been advised it probably need new plugs since none of the coil codes hit... should I still be concerned? should I still replace the plugs although the lights have gone out?

Tonight, during a short ride, all the sudden the VSC TRAC, VSC OFF and Check Engine came on. Atfter home, I got the P0057 code from a OBDII scanner. The P0057 code indicates O2 sensor on bank 2 lower sensor. However, the interesting thing is I also lost the power seat adjustment on the seat memory. When I switched between L1 and L2 , the mirrors and the steering position changes and the seat did not. However, the adjustment buttons on the seat itself work correctly. I wonder if this problem associates with P0057?

2009 LS600 ... Pulled up to a traffic light and noticed the red brake warning light had come on. When I went to pull away, the car would not budge! I turned the car off and restarted and it went fine.
Now, intermittently, the red warning light comes on and off. I tried googling this topic to see if there were any references to it happening but found nothing. It tends to come on when I'm slowing down but it has come on while normal driving as well.

I have had this 2008 ES 350 since 2010. Best car I have owned. EXCEPT for winter driving as the wheels stop spinning and it leaves you stuck. give me the old rear wheel drive any day. The main concern right now is, my dash has a red "brake" light that has been on for a week now. sometimes in the afternoon it goes out for a while. I have almost 42,000 mi. would that indicate I need to change the brake pads, which in turn lowers the fluid?

I'm occasionally having a scary issue with my '13 RC450h. There are a couple of parking lots where the transition from the parking lot to the road is not particularly smooth and the speed of the other cars on the road require that you get up to 50mph pretty quickly.
When I hit the gas then hit the bumps in the transition, the TRAC light turns on and power to the wheels is lost for a couple of seconds (exactly the opposite of what I want to happen). Is this happening to other people or is this something that needs to be looked at? Is this just a result of traction control and I need to remember to turn it off when leaving a parking lot and entering a busy road?

Installing one on a LS460L? Can you buy just the bulb and pop it in or is it a big wiring job? I think they are a pretty good safety feature (the way the crazies drive in this City anyway) and I assume it would be an easy DIY install?
