| I drive this vehicle almost everyday of the week. when i step on the brakes it feels like the anti-lock brake system is activating. this happens about five times a week. it happens, most notably, when the pavement is dry. i step on the brakes and feel the left front wheel abs kick in, after the abs pulsing stops the brake pedal goes down a considerable distance. it seems like it is only the left side and not the right side front brake that does this. this is a serious safety hazard as i don't know how the vehicle would respond in an actual ice/snow condition. *jb | |||

| I have a 1999 chevrolet s-10 pickup, extended cab, 4wd, zr2. when i purchased the vehicle used with approximately 70,000 mi. it was exhibiting the same premature abs lock up at low speeds, causing the vehicle to have unpredictable stopping distances, as the gm full size trucks included in the recent recall. i took the vehicle to a local gm dealer to have it diagnosed. the dealership determined that it was the passenger side, front abs wheel speed sensor. however, currently gm light duty trucks are not included in this recall. i feel that this may be of concern as i am sure i am not the only one with a light duty truck that has exhibited this type of dangerous vehicle behavior. i hope that the recall is revised to include all gm trucks including light duty ones such as mine. i had several close calls at gas stations, traffic lights and pedestrian crossings because of this. your attention in this matter is greatly needed and appreciated. because i have not had the vehicle serviced yet i placed the number 1 in the number of failures column of this form. *jb | |||

| When traveling over slight bumps in the road, the truck feels as if it has no brakes. i am not talking huge potholes or extreme dropoffs, but bumps as low as approximately. 2 to 3 inches. the problem happens most often near my home traveling at 35 mph, using the brakes to slow to around 28 mph when i hit the 2 to 3 inch bump. at this point the truck starts coasting and the brake pedal is stiff, approximately. 10 feet past clearing the bump the braking is restored. i don't know if this is normal for abs. *nlm | |||
