If it is under warranty and you have time to burn, take it in sooner than later. If the light stays on for a long time (ie: many days or a week or so), take it to the dealer. And that it is not a big issue to drive a short time with either warning light on. The GMC/Pontiac dealer said that the sensors are quite expensive to replace, and are many times replaced unneccesarily by a worried owner or a profit-seeking dealer doing parts swapping instead of real diagnosis. that can effect wheel speed and balance or the wheel sensors themselves. Seems these systems are very sensitive to extreme heat (over 100 deg F), extreme cold (below -10 deg F), freezing slush/ice buildup around wheels/brakes, internal moisture (condensation, not rain), etc. My kid did this and the problem went away and did not return. He suggested getting the car inside to warm up, or take the car through a carwash and pay extra to get the underbody wash. My local dealer noted that we had just gone through an ice-storm and very slushy roads, and said it was a very common problem with these systems. I told him to ignore them, and called our local dealer (no GM dealer in the small college town knows anything). This winter he called me from college a few hours away to say that the TC and Anti-lock brake warnings had come on. My kid drives my 2001 Bonneville that has a lot of bells and whistles (my wife hates that car). The brakes will always work but the RED brake warning light is cause for immediate concern in the general scheme of things. There may not be enough brake fluid for safe stopping and this should be examined immediately as driving may become dangerous.ĪBS/TC/ESC are all enhancements to the basic braking system so their failure won't endanger the driver. Your concern will be when the RED brake warning light turns on anytime after releasing the parking brake the RED brake warning light turning on now means something has occurred to lower the brake fluid in the brake master cylinder. Any time the ABS/TC/ESC warning light turns on while driving always leaves you with standard brakes. It would be wise to read your owner's manual for assurance and if not answered to call Saturn for a more definitive answer. whew.ĭoes anyone know if, when the ABS warning light comes on, the ABS is totally disabled and you have only standard braking? I don't drive fast enough in conditions (hopefully) to need ABS but would like to know I forgot to ask the Saturn guy. My Saturn Service Manager said whenever a wheel speed sensor "goes bad," it causes the ABS (Anti-Lock Braking System) warning light to come on as well as the Traction Control warning and Electronic Stability Control warning.
