the brake warning light ( on the dash ) is randomly going on and off, even at driving speeds. have had it looked at but no problems could be found. the brakes are fine ,couldn't find any wiring problems. some days it won't even come on at all ,and some days it does with no particular pattern.
View 1 RepliesI'm getting an intermittent brake light warning message on my otherwise perfect '04 V8. It is the bulb in the center part of the 3rd brake light. To replace it I looked for access from inside or outside. No obvious way to get to it.
View 1 RepliesIn my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.
Intermittent brake warning light and steady ABS light. Master cylinder is full and parking brake is off. Had a problem last fall with ABS and found rear caliper sticking, so I replaced all rear pads, rotors and calipers. Front brakes look good and I couldn't find any loose connections on ABS sensors. Thinking possibility that master cylinder might be the problem, or maybe moisture in brake fluid, as it has been below freezing here in Wisconsin, but it hasn't gone away now that its been a bit warmer.
View 3 RepliesI've got some issues with my 2005 Toyata Prius (~150,000 miles). My wife was driving recently and the "Master Warning Light", the "Hybrid System Warning Light" and the yellow "Brake System Warning Light" all came on.
Some quick reading of the owners manual said we should take it to a dealer right away, but because it was a yellow, and not red, brake system warning light it seems ok to drive at least to a dealer. in regard to the yellow brake system light the manual said it could be that: "the regenerative brake system failed or that the hydraulic brake system failed".
Now, I have a cheap bluetooth OBD reader hooked up to the "torque" app on my phone and I thought I would try to see what error codes there were to learn more. But strangely, it did not read any fault codes. I've used this reader successfully on my 2001 Mitsubishi galant, but I'm not reading anything for the prius in this case. I'm not sure if there is legitimately no error code associate with the warning lights or if my app is just failing to read them for some reason.
2001 with about 117,000. Just had it in to get the transaxle fluid replaced for preventative measure. Now I'm getting an intermittent triangle/exclamation warning. It seems to go off if I let it sit, mostly. Runs ok for the most part. But when that comes on, it practically limps on very little power.
View 6 RepliesI am the original owner of a 2007 LS460 with under 36K miles. Recently, my SRS (Airbag) warning light came on, but after I restarted the car it went off. However, shortly thereafter it came back on again, but it went off after I restarted the car. The last time it came on it stayed on. So I brought it into the dealer 2 weeks ago to diagnose it. They provided me with a service loaner ES350 and I'm still waiting for their decision as to what, if anything, they will do.
I discovered that on January 13, 2010, Lexus issued Service Bulletin Number 282827 in response to the National Highway Transportation Safety Administration (NHTSA) Action Number 10033557. Here is the Summary: "Lexus supplemental restraint systems. Some model vehicles may exhibit an srs light on condition with dtc b1861 and/or b 1866. After confirming the vehicle condition matches the bulletin, it will direct you to replace the instrument panel."
It appears that my LS460 matches that bulletin. Note that this is a Service Bulletin and NOT a recall, notwithstanding the fact that it pertains to a safety system, namely, SRS - the supplemental restraint system (airbags). My Service Adviser told me that because Lexus has not received enough complaints this matter has not been escalated to the level of a recall. He did not tell me how many complaints were received.
Because my car is out of warranty, my Service Adviser requested a courtesy repair from Lexus for the following reasons: (1) I purchased 2 brand new vehicles from this dealer (LS460 and RX350); (2) both vehicles have been serviced by the book; and (3) my LS460 has under 36K miles.
I would like to know if any other LS460 owners have experienced a similar intermittent airbag warning light and, if so, how that was resolved.
This is a 2006 Hyundai Sonata w/ 3.3 engine. 62,000 mi. The air bag warning light on dash comes on and goes off intermittently.
What causes this? What can I check? Is there really a problem?
A year ago I replaced radiator, long job in the winter in an unheated garage. After radiator was successfully replaced Air bag warning light started to come on intermittently. More so in cold weather, less so as it warms up. I know you have to be very careful working on air bag system, disconnect the battery and wait 10 minutes. I have heard that this is a known problem on Jeeps, this is a 1999 Grand Cherokee with 150,000 miles. I think ti ha something to do with connector in a dash, what can I do, a car is on its last legs, will not spend money on a dealer to fix, ripped off too often during life of car. I am afraid it will not pass an Ill environmental test (not related to pollution control) I suspect it is setting a trouble code but have not checked as of yet, hasn't warmed up in Illinois yet this year.

View 2 RepliesI have a 1996 Mercedes C220 with 60K miles on it. It runs great, but is giving me fits with inconsistent, intermittent, and (I’m pretty sure) incorrect warning lights, as well as intermittent gas gauge failures.
Soon after I bought the car about six months ago, the oil pressure warning light began to come on intermittently. Each time it came on, I checked the oil level and found it to be full.
At first it would come on, sometimes for just an instant, sometimes for several miles, but then go off and stay off for days or weeks. … Then it got weird … Each day as I was driving to work, the oil pressure light would go on - always within about 100 yards of the exact same place - about 10 miles and 15 minutes from home. It would stay on for 1/4 to 1/2 mile, then go off and stay off until the next day, when it would do the same thing again. I was still checking the oil level every day and finding it to be full; I have never added oil except when I changed it.
About two months ago I changed the oil and the filter. I put in Mobil 1 0W-40. Immediately after I did that, the oil light came on and has stayed on almost permanently. I say “almost” permanently because if I get to highway speed and then accelerate quickly, getting the RPM’s up to about 4500, the light will go off, sometimes for just a few seconds, sometimes for a minute or two, but will always come back on after I slow down.
Weirder still, immediately after I changed the oil, the coolant level warning light came on and has stayed on permanently. I have checked the coolant level every day since then; it has been full every time, has never gone down, and has never needed coolant added.
Here’s another issue that may be related. The gas gauge intermittently drops to empty, even when I know for sure the tank is not empty. Sometimes it shows the correct fuel level, sometimes it shows empty. Sometimes it will bounce back and forth between the two several times within my 1/2 hour drive to and from work. It does this with no pattern I can discern. It has been doing this as long as I have owned the car.
I have hooked up my Actron OBDII code reader to the car several times. It never shows any outstanding codes, any pending codes, or any other problems.
Although these issues worry me a bit, I have been willing to live with them, assuming there’s really nothing wrong with the car. But now I’d like to sell it - for reasons completely unrelated to the warning lights - and I’m pretty sure no sensible person would buy it if they test drove it and saw the warning lights. (And I think most people would notice if I covered them up with electrical tape!)
I have a 2007 Toyota Camry with electrical problems that started showing up recently. One day the check battery light turned on and about 15 minutes later the AC would lose power intermittently. After parking the vehicle that day I tried to start up and only heard a rapid clicking sound. I exchanged the battery since it was still under warranty and everything seemed to work fine for one whole day. The next day the battery light turned on again, followed by the ABS warning light, and then the airbag warning light. Within about 5 minutes the dashboard back light started flickering and other warning lights started lighting up randomly. Within a minute of that the car shutoff and would not start back up again.
View 2 RepliesI replaced both rear pads calipers on my jimmy. Its 4 wheel drive. Now after installing them, I tried to them, and i nothing from the bleeder valve s. Someone said I could have the wrong caliper on the wrong side? Is that even possible? Also, the manual food this truck says it may be necessary to use a scan tool cycle/bleed these brakes. Ive changed calipers etc before, never had this issue on other vehicles.
View 19 RepliesWe recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.
2002 santa fe gls v6. I recently brought the car used and it appears to be in great shape with 135,000 miles, however the car has issues which I'm hoping are minor. Here are my questions:
The brake light and battery light stay illuminated, can this be a bad alternator? Speaking of alternator there is a rattling sound coming form the alternator area, do the bearings go bad? If it is the alternator, does it matter if I use a 95 or 110 amp? Is the alternator difficult to replace?
There is intermittent jerking when in drive. Is it possible that a malfunctioning alternator not delivering proper voltage can cause this type of issue possibly affecting the system computer? Could the jerking be due to something else like crank position sensor?
Lexus has diagnosed a ground fault with an intermittent connection.... I am not sure how to proceed ... Could it be a light bulb connection... or does it even have these? Can the part be serviced in place... or must I replace the whole assembly?
View 4 RepliesI've had the brake pad warning light intermittently come on and off in the last week. I took the front left wheel off and had a quick look and there is still 10mm of pad on the outer, also the connection going to the pad seems to be fine.
Is this warning light just an over precaution from VW and I still have plenty of meat left on my brake pads and km's, or should I thoroughly check them all or take it to the mechanic to be on the safe side.
I was driving home and i got a sensor light ive never seen before(at least its not an o2 sensor cel!!!!!!again )about a mile or two from the house today. ,so i drove on to my indi mech.appx.1mile from house and he looked at it before i even found it in the manual, he mentioned it was a low brake pad warning light,so my next questions are i didnt hear or feel anything different ,and i use the tip trans whenever i can but in the 40,000 miles my wife and then me driving it i guess its due,.probably wasnt checked at inspection ,....so is there any possible caliper damage from waiting till i saw the light ,or is it usually just pads and rotors replacement at that point,and how much can it be driven untill i gets an in for appt.at the shop with pbr dustless pads installed this time .......
View 5 RepliesYesterday while doing a test run on my car, I had the "low brake pad" warning light come on in my car. I pulled the front wheels off to have a look and the pads looked fine. I followed the sensor cable to see if there was a short/open in it and I found on the vehicle-side of the wire harness that one of the wires came loose and detached from the harness. (that isn't a phenomenal description, but I hope you at least understand) Needless to say, I think I need to replace the wire harness. Is there a part number for JUST the plug, or am I looking at a whole assembly? With the searching I did, the only info I found was to short the circuit by cutting and splicing, but I would much rather fix it the right way.
View 5 RepliesI have recently had an issue with the brake warning light coming for 15 seconds or so after navigating a freeway cloverleaf etc. It doesn't come on under any other circumstances. Of course, this sounds like a low brake fluid issue (fluid moves to one side of the reservoir in the corner, causing the sensor to report the fluid is low). However, I have checked the fluid level in the reservoir, and it is very near the full line. I see no external evidence of leakage anywhere (not surprising since the fluid level in the reservoir isn't low), and the brakes work exactly as they always have.
I know the brake light can indicate problems with the traction battery (brand new, in my case), but that doesn't seem to be likely considering the consistently intermittent nature of the warning light illumination. Does the brake warning light monitor anything else other than certain traction battery issues, brake fluid level, and the parking light being on? Is the sensor for the brake fluid level a simple float like I have seen on other vehicles?
