Lexus RX 2010-15 :: Trac Light Turns On - Power To Wheels Lost For A Couple Of Seconds
Sep 5, 2013
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?

So im driving home and i realize one of my headlights are out. I get home and turn them and turn them back on and the headlight turns very dim for a couple of seconds, and then shuts off. What this could be? Ballast or Bulb. I have major modifications done to the wheels wells to fit the wheels, so i don't want to take it to the dealer.

I own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.
The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.
I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.
I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?

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.

My carmy had run for 82000 miles now, and never had a problem til now. When I start the car, the "check engine light" turns on. When I go driving, after 2 seconds the car slip warning light turns on.
Both warning lights keep on blinking all the time. Here's a photo of the warning lights: [URL] .... I mean the photo at the row in the middle, with the car sign on it.

I have a 2007 GS350 AWD with about 110,000 miles right now. For almost the last year or so it has been burning off some oil. By the time its up for an oil change, it occasionally gives me the engine oil low light. It stays on between a few seconds to a minute and then turns off.
I've been telling this to the local Lexus dealership where i've had all my maintenance done, and they eventually did an oil consumption test. They said it was losing about 1.5 liters after 3,000 miles. They say that is within spec.
This issue came up several times while i was still in my 100,000 mile warranty, but they wouldn't do anything as it was in spec. I don't see how i should get a low engine light warning every 3-4k miles and have been pushing them to do something and cover under warranty since it has been documented as an issue before the warranty ran out. Lexus corporate asked for a compression test (which i had to pay for), the results are below:
Cyc#1: 205 dry; 225 wet
Cyc#2: 200 dry; 215 wet
Cyc#3: 190 dry; 215 wet
Cyc#4: 200 dry; 225 wet
Cyc#5: 205 dry; 210 wet
Cyc#6: 190 dry; 220 wet
After Lexus received the results they asked for, they still said: well the oil consumption is in spec so won't do anything.

Once this happens, simply turning the ignition off and then on again seems solves the problem. We've taken the car to two mechanics, one who said the belt was slipping and one who said the belt was fine!

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?

My 2010 S has a wicked knock for a couple seconds at startup when cold. It only does it after it has at for a few hours. What this could be? There's no check engine light coming on.

Tried starting the truck, fired ran good for a couple seconds, then ran extremely rough for a couple seconds then died.
I did some research and changed the ICP because there was oil in the connector so even if it wasnt causing my issue i wanted to replace it.
Now I have the same issue but it will actually run a little longer and not stall. I thought it was fixed so i took it for a drive, after about 3 miles it bogged down and i was able to make it home with half throttle going about 30mph. Sounds almost like its running on half the cylinders. i unplugged the ICP and it continued to run that way.
I had done the 50cent mod a few years back with the peices from ford but i know the harnesses themselves can wear through so i checked the resistance between the center pin and the two pins to the right and left for both the injector harness and they had about 3ohms.
I am leaning towards an IPR but from the reading i have done it seams like most trucks will not restart after they die. I have AE so i am going to hook it up later today, just wanted some reccomendations on what to look at.
I also remember when i shut it off the unplug the ICP to see if it would clear up the needles on the gauges did a full sweep as if i disconnected the battery which i though was weird.

I have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.

Yesterday my truck began to give me some problems starting. The engine turns over just a couple of times then it sounds like the starter disengages and winds up. it took multiple attempts but it finally fired up. Does this sound like the starter or could it possibly be the starter relay?

I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?

My 2015 Lexus RX 350 has been indicating "Check AWD system, TRAC off" for sometime now. It all started when I overfilled the tank and it spilled over. The indicator came on after about 12 hours. What may be responsible. The car is barely 6 months old and don't know what to do right now.

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.

Driving in city. First sign was battery light illuminated in dash. Then it went off, then back on. Radio shut off. Then all warning lights illuminated in dash. I'm still driving about 40mph to my destination. GPS goes dark. Tech needle goes to zero, then speedometer goes to zero. I'm still driving approximately 30 mph. Lost headlights. It's dusk. Lost all lights in dash. Slowly moving now and looking for a place to park. Now losing engine power. Coasting to curb. Lose all power and mobility. Call tow. Thought I could smell a slight electrical burn from under hood.

Enjoying some nice below zero weather in Chicagoland. Getting a bit of a squeel for the first couple of miles from my 2012. I think it may be a belt.

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.

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.

Noticed that motor turns over for roughly 3-4 seconds before starting when their GX has sat for awhile in well below freezing temperatures?
It's not slow turning over just takes a little bit longer to actually catch and start.
When the motor is warm or the outside temperature is closer to freezing or above I find that it turns over for no more than about 2 seconds before it starts.
I am thinking the longer turning over when cold is a good thing since the motor is starting to pump oil when it is turning over and allowing the internals to get lubricated before starting and revving.
