    brake light and battery light both on

  • Anonymous Nov 18, 2008

    2001 Elantra, i think the charging light (battery) illuminates the brake display. I am pretty sure the battery is not charging for some reason. I have the same issue and my battery was dead a few days back but did take a charge.

    We just experienced the same problem. These lights stayed until finally the car died last night. Brand new battery, so its not the problem. Several people say its the alternator including guy at Advanced Auto Parts. We are working on replacing that now. Watch out, your car may die on you. Our lights were coming on for about 5-6 days before it finally just shut everything down.

My 1991 Corolla's battery and brake warning lights came on simultaneously and would not turn off. The car otherwise starts and continues running with no issues. Needing expert advise.


Never assume that two lights coming on is something more than it is.
You have a problem with your charging system.
You have a problem with your brakes.

The fact the car runs without issues is reasonable to expect. You can run a car with a brake problem. You can run a car with a battery charging problem with no problems until the battery becomes flat.

First check your brake fluid reservoir. There is a float and sensor that tells when the brake fluid is too low. Just top it up.

If that is OK, the disc pads have wear sensors. Yours may be getting thin.

With the battery light, you need to check that the alternator is pumping out 13.5 volts using a test meter. If it isn't check for a slipping belt. If that seems ok, go to a tire, battery and exhaust place for full diagnosis.

Red spanner warning light


Brake Light. Make sure you are not driving with hand brake on. Check brake-fluid level. Top off brake fluid if low and make appointment to check brakes. Driving with brake light can be dangerous; deal with this soon. Call tow truck or drive carefully and slowly to shop.
ABS (antilock brake system) Light. Indicates either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid and make appointment to get brakes checked. Call tow truck or drive carefully and slowly to shop.
Oil Light. Either engine is very low on oil or there is no oil pressure. Pull over and turn off engine immediately. Check oil level and add oil if low. Turn engine back on to see if light has gone off. If oil light is still on, bad oil pump (no oil pressure) is likely. Call tow truck.
Check Engine Light. Car's computer senses engine problem. Difference in performance may not be noticeable, but make appointment to have car diagnosed. This usually cost around $65-$75 to do. OK to drive. If problem is serious, computer may switch to limp-home (low-power) mode and you won't have option of waiting to bring car into shop.
Air Bag Light. Get air bags checked. Problem could prevent them from activating in accident. OK to drive, but not safe in accident.
Battery Charge Light. Alternator is not charging. OK to drive, but turn off any unneeded electrical devices (radio, heater, defroster) and avoid starting engine more than necessary. Bring car into shop soon to avoid getting stranded. When alternator is not charging, battery loses charge and car stops working.
Emissions Lights (O2 sensor, EGR, check emissions). Depending on car model, these lights may indicate problem with emissions sensor or may light up at certain mileage, usually 60,000 miles (100,000 km). Get sensors checked. OK to drive. If problem exists, car might get poor gas mileage.

SIDE BRAKE AND BATTERY LIGHT INDICATORS COMES ON AND OFF WHILE DRIVING,CHECK BRAKE AND BATTERY FLUIDS AND THEY ARE W/IN HI LEVEL.


The battery light indicates the charging system has a problem not a defective battery. as for the brake light that is unrelated and may be due to low brake fluid in the master cylinder. Have the Alternator tested to see if the output is within specs

The battery light and the brake light come on. This just started yesterday. We replaced the battery and front brakes two weeks ago. Is this just a glitch in the computer?


When you replaced the battery, did you have the alternator tested? The battery light indicates either the battery is not holding a charge or not receiving the proper power from the alternator to charge the battery.
The brake lights could be a glitch but it could also mean that you are low on brake fluid or you have air in the brake system. Suggest you at least check the fluid level in the master cylinder and bleed the brakes.

I have a 2002 hyundai accent. I just replaced the battery yesturday because it went completly dead. my battery light and parking brake light is on and wont go away. THis morning my brand new battery is...


It really sounds like maybe that alternator is bad. You can get it checked at a local parts house like an AutoZone, Advance or Pepboys. They can check the voltage at the battery with the car running, it should be above or around 14 volts, if it is lower then the alternator is not working properly. You should call and check to see if there is a warranty on this alternator if it went bad so quickly, but every shop and parts manufacturer has different warranties.
I can't say that that brake light is directly related to this but you should definitely check and make sure that the fluid level in the reservoir is at the proper level. The brake fluid reservoir is under the hood on the drivers side of the car right up by the firewall (the wall that separates you from the engine bay). It is usually a cylindrical container. You should see Max and Min fluid level marks. Make sure the fluid is in that range. If it is not you make need some brakes replaced. If the fluid level is fine it may be related to the fact that the battery is running low voltage, car computers get wacky when they do not get the proper voltage to them.

I have the brake and battery warning lights on at the same time what is the problem since the car is running ok


battery light indicates alternator is not charging. It may run fine until the battery is dead, but then you'll be stranded wherever it dies. Recommend taking alternator to parts store for testing. Once alternator is fixed, brake light may go out. If not, check fluid level in reservoir. If it's low, you may have a leak. Get back to me if you need help getting alternator out or brakes fixed, etc.

Brake light abs light battery light on windows rolling up and down slow and power window barly working


brake light- check level of brake fluid.

abs light- have car scanned with ABS Brake Scan Tool (OBD-II compliant).

battery light- The alternator probably is not charging the battery enough when running. Possible bad battery if one lets it go too long.

My brake light and battery light stays on when driving. Also emergency brake does not work.


OK, the brake light is caused most likely by the emergency brake cable being broken, and the pedal or brake lever is not in position.

Also, the brake light could be caused by low brake fluid level. Check that, too.

Battery light, is caused by the charging system not working, like a bad alternator or shorted out battery, or both.

I would have these issues repaired before driving any distance.
