Brake Antilock Wheel Speed Sensor problems of the 2006 Chevrolet Equinox

Bought my 06 eqinox in may of 2015. Day 2, battery died. Dealer put new battery in. Next week, battery dead and took out stereo with it. Dealer replaced battery and stereo. Now having trouble starting again. Have replaced brake pads and rotors twice on rear wheels and front once. Car makes grinding noise still when backing with foot on the brake. Abs and tc lights came on may of 2017. Had checked out and needed front right wheel speed sensor replaced. Replaced it and light stayed on. Had it rechecked and it still reads the same. No brakes. Pedal stutters on the way down and then has to be forced down the rest of the way to stop the car. Had mechanic look at it and was told to replace abs module. We did and I finally have brakes again but now my break light is on along with the abs/tc lights. Car has sunroof. Had car 2 years and all of a sudden my back floor is flooded. Thought the kids spilled water. Nope. Soaked a beach towel cleaning it up. Next hard rain, flooded again. Lines are clogged and backing up into my car. Two beach towels and two gallons later of water vacuumed up and my padding is damp and still stinks like mildew. This car is badly designed. The brake situation is very dangerous. Luckily there was an empty turn lane beside me when it rained or I would have hit the car in front of me. The brake pedal would go to the floor when turning and wouldnt stop on straightaways. The electrical wiring in the drivers side door is jacked up too. Can't unlock the doors, turn on dome light and doesn't shut off radio.

Grinding, moaning, starts unsafe stopping distance and happens out of blue, abs/tc lights off and on, so far everything I have read online it seems to be a wheelspeed sensor or harness. At times brakes will also be hard as rock no warning and have no brakes at all. Been happening for awhile off and on.

I am submitting information to report a safety complain in regards to a 2006 chevy Equinox. I have had brakes and brake pedal issues for several months now in both city and highway driving. The issues occur at attempting to stop at stop signs and stop lights. This is the first of any major issue with my vehicle. My issues are break resistance and vibrations. Along with getting my brakes and rotors fixed and/or changed earlier in the year, I started feeling brake vibrations initially. After getting the rotors checked, it happened soon after and "graduated" towards a resistance where I was unable to stop or slow down unless I pumped my breaks repeatedly to release the pedal locking. I recently got my left front speed sensor and hub assembly replaced in hopes it would fix the issue. 3-4 weeks later, the resistances has seem to got a lot stronger/bigger. It has almost caused me several accidents at the stop light and I am now trying to save to get this issue fixed as I was quoted about $2k initially. This is a safety hazard to any vehicle and Equinox that has this issue. I have saved myself from several accidents with quick awareness and action and but I am not sure how lucky others have been. The resistance in the breaks and vibration is very noticeable and continuously happens until the abs and traction control lights up on the dash board indicating they are deactivated/disabled. This is when braking becomes much easier with little to no resistance and vibrating. Between the speed sensor, hub assembly, I have spent just over $1k in expenses and this will continue to rise with the next repair of wire harness and/or replacement of abs system in hopes it corrects the issue. Please consider my complaint in hopes of recall to prevent further issues and potential accidents to innocent people.

The contact owns a 2006 Chevrolet Equinox. The contact stated that the abs and traction light warning indicator illuminated. Also, the contact mentioned that when the brakes were engaged the vehicle made a loud grinding noise. The vehicle had been taken to the dealer twice and the mechanic replaced the left front hub bearing, the wiring harness and connected the lose connection speed sensor. The failure recurred for the fifth time and an independent mechanic replaced the front brakes. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 110,000.

I have a 2006 Equinox which I bought in 2010. While I had various "of age" repairs, such as fuel system issues and a fan motor; with the age and mileage, they seemed normal. In 2013 I replaced the egr valve and transmission speed sensor simultaneously; as the code was for egr, but would only intermittently kick in the tss code (the car died in the middle of traffic 3 times before I could get the code to stay so we could find the problem). Among looking online for the problem, it was common, but my dealer would not fix without the code. June, 2014, the brakes started pulsating on the car in low speeds. I would have to pump the brakes to get it to stop. Twice, pumping the brakes at an intersection failed, and nearly resulted in a wreck with my daughter in the car. The abs and tc lights would come on intermittently. I took it to a mechanic: he evaluated each connection and cleaned them, where the abs harness connects to the main harness. He found no discrepancies. After 2 more months of dangerous driving, and a whole new set of brakes (all 4), online research prevailed once again. This problem was common; and suggested a rather cheap fix. The 18 in wire harness from the wheel speed sensor to the main harness had an issue. Sure enough I, a woman, after being told the dealership didn't carry the part, ordered it online and replaced it in 15 minutes. No problems since then. May, 2015. What appeared to be a thermostat issue ended up being a coolant reservoir problem. The reservoir was broken, where the plastic nipple that comes out the bottom attaches with the hose. After I contacted all parts stores in the area, I was told while it was common for Chevrolet trucks and Equinox vehicles, the Equinox part was no made available to the parts stores. I had to special order online, thank goodness it worked.

While applying the brake, it pulsated and the abs/traction control light came on. We took it to the Chevrolet dealer we purchased it from for repair. They replaced the left front wheel speed sensor/hub assembly and the front brake pads and resurfaced the rotors. Approximately one week later, the same issue occurred again with the abs/traction control light on again. The abs/traction control light is on. As you brake, the brakes pulsate like they are trying to adjust themselves. This is scary as you fear you are not going to stop or rear end someone every time you drive the vehicle. We need to trade this vehicle in, but who wants something Chevrolet won't or can't fix?.
