| Since the middle of last year, we experienced a problem w/abs brakes. when you would slow down & get to about 20 mph, the van would start to lock up rendering the vehicle out of control & unable to stop. we took it to our usual mechanic who determined the sensor on the driver side was bad & replaced it. that lasted about 6 months & we had the same problem reoccur. again, our mechanic looked at it (pulling his hair out mind you) & determined that there was unequal voltage, so he replaced both sensors. now again we started having the same problem. as of today, the abs light is on & the system is not functioning. we are not having any problems stopping now. anyway, i've done some research & noticed that a good number of gm vehicles have had abs recalls, 1 story i read was the exact same problem. i requested several things from gm. 1) direction to go now; 2) reimbursement for these expenses(approx $800); 3) arrangements to have this problem corrected the right way & 4)a recall be placed on this particular vehicle also. if there was a recall placed on it, we did not receive it in the mail. unfortunateley, i was sent a reply basically saying that the 1996 model was not included in any recall. if i feel there's a failure, then i should visit a local dealer to have it checked out (at my own expense probably). there's an obvious track record with this abs system, however it doesnt seem like they want to take responsibilty for it. | |||

| My vehicle was moving about 10 m.p.h. in preparation to stop behind several vehicles at a red light. i applied my brakes in an attempt to come to a complete stop; however, the brakes failed to engage. i then put full pressure on the brake pedal. the pedal went down almost to the floor, but the brakes failed to stop the vehicle. as a result of this brake failure, my vehicle struck the vehicle in front of it which in turn struck a third vehicle. my vehicle was towed to a mechanic who was able to duplicate the failure. at this time however, he is unable to determine what is causing the failure.*ak | |||

| I had the air conditioner replaced in dec. and in feb. i had just driven in from ga to ca and it was 7:30am in the middle of traffic and the front of the air condit. unit fell off. i heard what i thought was rocks hitting under the front end and later found out it was bearings, but just as i heard the sound i lost my power steering and brakes. i had no brakes at all .. i hit my emergency brake slowly and power steered my van to the side of the road. it took everything i had to turn the wheel . if i had been going 60 on the freeway instead of 10 miles an hr. i probley would have been in the biggest trouble of my life. i could have killed someone not having any brakes or steering, somehow the two are connected. i have never heard of this happening to anyone and when i spoke to different auto repairmen. they have not heard of it either.. i had replace the ac in the van in dec, and paid 500.00 . i have had on going problems with the ac from the time i first got the van. i hope no one ever has this problem or hurts someone because there air conditioner falls apart. the running of the auto and the connection to the a/c should never be hooked together. ac's go out alot in auto's and this is a sure way to kill someone.*ak | |||
