2000 GMC Sierra 1500: ABS light or ABS activating

Filed Jun 2, 2020 · Engine, Suspension · 270,000 miles · TN

I've had several problems with the truck since I bought it 3 months ago. I've fixed almost all of them-ABS was activating which was pushing me into traffic nearly causing a wreck so I changed the ABS speed sensor and hub assembly. Front suspension was gone so I replaced that; as well as steering parts, brakes, the parking brake doesn't work, fixing it next. Oil sending unit, A/C belt and refrigerant replaced. The problems left are evap emission vent valve solenoid, throttle pedal position sensor, and random/ multiple cylinder misfire sometimes and cylinder 4 misfire other times. In 4x4 when it gets under a load something sounds like it's binding up and it pops but it still works. When I shift into drive or reverse or accelerate from a stop it has a shift feeling in the rear with a thump sound. Sometimes I can push the gas and it won't downshift to speed up when I'm on the hwy but that's probably the tpps. I just want my 4x4 working and my shift thump from a stop to go away. Help. In 4x4 the noise happens in fwd reverse and when turning and worse in 4lo but happens in 4hi and auto but not in 2hi.

Tl* the contact owns a 2000 gmc sierra 1500. The contact stated that the vehicle was repaired per the federal safety agency campaign number: 05v379000 (service brakes, hydraulic) by wehr ford (11311 us-60 bus, mountain grove, mo 65711, (417) 926-3192). The contact stated that the dealer only cleaned the ABS sensor for corrosion. Years later, the brake pedal failed to respond due to internal corrosion regarding the sensor. Also, the ABS kept intermittently activating and caused extreme difficulty when braking. The brake pedal failed to stop the vehicle and caused the driver to have to reverse more than twice to prevent a crash. The dealer was notified of the failures and indicated that the ABS sensor may need to be replaced. The vehicle was not repaired. The manufacturer was notified of the failures. The failure mileage was not available.

Went to stop and the brake pedal pushed against my foot instead of going down. Was moving slowly and the brake pedal instead of stopping the car pushed my foot up from the brake pedal and I went over a parking brake. Mechanic verified that when wheel sensor goes bad the vehicle thinks the brakes are locking up and the ABS system goes on pumping brake pedal. Happened multiple times as approached stop lights pushing me into intersection instead of stopping.. I believe when the wheel sensor is bad it should not put me or others in a dangerous situation.

During a normal stop at a stop sign on a rural road, a steel brake line ruptured due to excess corrosion. This one line between the master cylinder and ABS module is the only line that provides pressure to the front brakes, which supply roughly 75% of the vehicle's braking power. The rupture resulted in rapid fluid loss and therefore a lack of pressure in the hydraulic system to allow for adequate braking. Needed to swerve into a ditch to avoid a crash with cross traffic.visual inspection indicates most brake lines are extremely corroded, and were obviously made with substandard materials as compared to other manufacturers. I do recognize that this is an old vehicle, however other vehicles of similar age and driven in similar environments do not have this issue. Online research, most notably the complaints filed to the federal safety agency, indicate this is a common problem with chevy/gmc trucks of this era. Although other oem's (subaru) have issued recalls in similar situations, it appears that the gm that the public bailed out just a few years ago has decided to deny that this is a problem, gambling that the the cost of lawsuits associated with deaths do not exceed the cost of a recall.

Had a recall on the brakes, recall # 05068. Classic cheverolet (now out of business did the work) they only cleaned the parts, ABS light came back on a few months later so they just kept cleaning them until my warranty expired. Then when I brought it back it all of a sudden need over $2000 dollars of repairs. My wife got them to kick in a $1000. But I believe the parts should of been re manufactured out of stainless steel so they didn't rust & I wouldn't still be having his problem. Now I'm probably looking at another $2000 to continually fix the same issue. They basically did the same thing with the tail gate recall, just replaced with new parts of the same mat'l as the ones that were rusting and failing in the 1st place. So I replaced them since then again also. Which if they would of made them out of galvanized or stainless they would of held up better.

I started smelling gasoline and found a corroded fuel line at the junction between the nylon line leading from the fuel pump to the steel line going to the fuel filter. Doing repairs, the hard brake line leading from the ABS unit under the driver's seat area to the rear flex line connector was leaking badly as well at the rear-most fitting. Purchasing these lines separately cannot be done, so I'm replacing all of the fuel/brake lines myself. I'm using stainless tubing for the brake lines not provided by factory gm parts.

On my way to the store I noticed reduced brake pedal and increased stopping distance. No warning lights were on at this time. On my way home the brake warning light came on and I had even less pedal and needed extreme stopping distance. I went directly to the repair station and the mechanic found heavily rusted lines especially in the areas of the ABS module. One of the lines was rusted thru and leaking in the area of the ABS module causing the malfunction. I already have had the brake lines to the front calipers replaced in july of 2012 due to extreme rust. I am having all the brake lines replaced with stainless steel at the time of this posting. This vehicle gets very light duty personnel use and shows no signs of rust in the body.
