Question about 2005 Buick Rendezvous

1 Answer

AWD light and antilock light comes on.

I have a 2005 Buick Rendevous. The brakes get mushy sometimes when coming to a stop, but will pump back up. Now the AWD disable and the antilock lights come on. They will come on and stay on until you turn off the car. When you turn it back on the lights are off until the next time. The strange thing is this happens very randomly. It's not a constant thing, but is getting to be more often. I have only had the car 1 1/2 mths. It has 65000 miles on it. Thank you for any help you can give.

ABS brake noise at every braking; Also sometimes the warning lights(AWD Disabled) comes on while driving and other times the lights don' come on;;AWD still works tho.

Sounds like you need new brake pads , when the pads get worn it triggers the warning replace the brake pads reset the computer this should fix the noise and the warning lights.

I need a transmission,and need to no if my car is an awd or fwd also when i push on the brakes to stop if feel like the pad is push my feet back up and jerking what do that mean awd light comes on...

if you have an awd light coming on then you have an awd transmission(car).if the brake pedal is pulsing while pushing on it to come to a stop then it sounds like the rotors are warped and need replacing.this can be caused by alot of heat build up on the rotors,a lot of miles on them,the wheel nuts were not torqued when tightened,rotors are rusting and coming apart,a loose brake pad moving around.get the brakes checked.

Hi the abs light has come my dash board ,what do i have to do to repair problem .thanks

hello andre..... when the abs light comes on it is usually do to a bad sensor. In order to check and see which sensor is bad you have to put the car up in a lift and test each one. IF you still have the antilock braking action occurring you know it is only a bad sensor. If there is no more automatic pumping of the brakes in a hard stop the antilock brake system is bad. THE good news is the brakes will still work, you just have to pump them yourself. Joe

Thanks for choosing Fixya!

2003 buick rendevous brake lights stay on even with engine off and keys in pocket. I have checked fluid level, put in gear, forward and reverse, and held brakes to see if sticking or mushy, appeared ok....

You will need to check the brake switch operation & possibly reset or replace it with a new one. It may just be out of adjustment. Look up under the dash, drivers's side & you will see the switch about half way up the pedal. See if switch is stuck or out of adjustment. A little silicone spray may free it up if that's the problem. Good luck!

Abs sensor light wont go off my 2005 polo

Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. ANTILOCK systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. The grinding noise could the the ABS pump or your brake pads could to worn to the metal backing and grinding against the brake rotors. I recommend a inspection soon for your safety.
