After driving for either 1 mile or sometimes 18 miles the ABS and Brake light come on at the same time. Sometimes when I stop and turn off engine and re start the light stays off for awhile but usually comes back on.
brake and abs light comes on while im driving, i pull over turn off engine re-start and goes away, but lately is very often and it does not go away
2004 gmc safari all wheel drive-ABS LIGHT STAYS ON ALL OF THE TIME. BRAKES GO TO THE FLOOR ON OCCATION.
I AM WONDERING IF THEY WILL GO OUT COMPLETELY. DON'T KNOW WHAT TO DO. HAVE TAKEN IT TO THE SHOP ON SEVERAL OCCATIONS AND IT HAS NOT HELPED.
brake light & ABS light come on & stay when engine is started
was told I need a new anti lock brake control module
cost $900.00 for part + labor
I CHANGE THE MODULE CLEAN FRONT ROTORS VERY NEAT, DISCONECT THE SENSOR CLEAN IT UP THEN BACK TOGETHER DISCONECT THE BATTERY USE MY SCANNER RESET EVERYTHING AND STILL HAVE THE PROBLEM
abs light always on. have not done anything yet.
Both brake and abs warning lights came on intermittantly. Brake ABS unit was replaced.
Light comes on intermittly when I hit a bump or just starting the engine and occassionally never comes on.
ABS went out after only a few thousand miles but unfortunately after the warranty had expired.
Repair shop wanted $1500 to repair it. I've been waiting for a recall on this as I've heard it's a common problem with Safari and Astro vans.
Also I've driven without ABS for about 30 years.A few more won't make any difference
I have replaced the ABS module now 3 times in the last year.(The dealership has paid for it twice). Does anyone know what the hell is going on? The last module lasted less than 24 hours.
haven't fixed it yet...ABS module must be replaced/rebuilt...$$$
brake light wont go off sometimes when braking goes hard to right have to let off brake and pump peddle untill it straitins out
Abs and brakes shows in my deshsbord
The brake light and ABS light comes on after drivina between 2 and 20 miles. We recently replaced the brakes in the rear thinking that might help but after driving 150 miles thay came on and are doing the same thing
i was looking to see if this has been a recall. we have not had it fixed as just like others, the lights come on and off...sometimes come on as soon as start car, other times wont' come on for a half hour or so. light will stay on until car is shut off.
Sometimes after driving for five minutes , both "BRAKE" & "ABS" lights come on. My mechanic says it will cost around $1.700 to fix... After reading the other stories and the repairs aren't a sure cure.......I think I'll just ignore them.
ABSOLUTELY Light on
not repaired
My problem is the same one that is described in the original problem report. The only exception is that the problem manifested itself soon after the vehicle's warranty ran out. This happened around 55000 miles.
ABS system does not engage when braking firm & hard (basically you have regular non-ABS brakes. ABS & Parking Brake indicators on dash board remain lit after engine start. When going for State Safety Inspection, make sure the indicators are off. Can't afford a $900 fix on a 14 year old van.
