 Was driving and a truck pulled out of drive way in front of me. hit the brakes and they worked for a split second but then went out causing an accident. since that they brake tight and abs light came on and continues to stay on at all times now. i do have brakes just not anti-lock. have checked the whole system to fix and found that it is a common problem. the abs module is no longer available so can not remedy this problem. i live in a state that has safety and emissions tests that it will not pass. i have done research on this issue to try to get fixed and parts for hours to no reveal. this item should be a recall due to the danger of failure and number of complaints. also most people will not report these problems because the brakes still work just not the anti-lock part of iut after all my brake pedal is not spongy or low in anyway actually they are good. i cannot even find a good one in the junk yards as i have bought 2 units and both were bad so had to return them. what a waste of 8 hours total to find that they had same problem. i have 192354 miles on it now and still runs strong. i feel that each time i drive it i am taking a risk of hurting other people including myself. we cannot afford to replace this vehicle so it is like playing russian roulette when driving. gm needs to fix these vehicles before any one dies and they get sued (if this hasn't already happened). like i said it has been a great reliable vehicle other than this problem. so everyone that does have this problem needs to report it so gm is forced to address this problem. *tr

 When steering wheel is turned the brakes are activated. when parking, the brake pedal travels when the steering wheel is turned. the farther you turn the wheel the harder the brakes are applied. at higway speeds, around moderate curves, the brakes are applied and the cruise controle is deactivated. we are not sure how this part functions ( power assist, steering), but we are concerned that the brakes are activated with a slight turn of the steering wheel at highway speeds. on wet roads or in avoidence situations if the steering mechanism activates the brakes, loss of control of the vehicle may occur. *ak

 We have had problems stopping the van. when you use the brakes you must be very very familiar with them and not hit them hard, they must be applied very gently otherwise they will not stop the vehicle. it will just keep on going they lock up or something, i am not a mechanic and the word lock up might not be right. the bottom line is they do not stop the van if you do not apply just the right amount of pressure. in an emergency they would be extremely dangerous. we always just lived with it and adapted, but it is not right i think. *ak
