Abs light on
Two weeks ago driving 60mph on highway in snow engine light illuminates and lose total power. "reduce power mode" illuminated but engine shut off. We almost got rear ended by a tractor trailer on [xxx]. On side of road for 2 hrs in 20 degree weather waiting on aaa (no shoulder on hway) and motor starts. Take it to garage and get throttle position sensor (tps) code ans stabilitrak/ABS code. We had accidentally hit the onstar button a minute before this and mechanic thought that was related so he cleared code and sent us on our way. For two weeks we were good andit happened again on highway in rain [xxx] this weekend, again in middle of highway. This time car started after five minutes. Took car to dealer and they state the tps needs replacing and front wheel speed sensor broken. There is a gm service bulletin #11273b where gm acknowledges tps issue and covers replacement of tps for 2008-2011 vehicles. Also bulletin pip3089b for bad wiring to tps for 2003-2006 avalanches. Gm denied my service despite the fact that a 2007 tps and throttle body are the same exact part number as the defective one. This is super dangerous and extremely frequent as there are 550 posts alone on [xxx] as well as many reports to [xxx] please assist as they are not standing behind a defective and deadly product as the computer cuts total power right on highway...

My vehicle has a kelsey hayes ABS module that has already failed twice. First at about 75.000 miles and now at 130.000 miles, always while driving. The module was recalled in 2002 and the manufacturer was given a chance to redesign it, but it is still a bad part. The blogs are full of owners constantly complaining about this. I had to take gm to the mat to replace the first one since the truck was manufactured after the first recall. This time around I didn't have the time or patience to do so an went ahead an replaced it out of my own pocket. Ia m also stuck with this part as it is not replaceable with any other brand. This is a dangerous glitch that needs to be addressed before someone gets badly hurt. In addition to this problem, the location of the unit (outside the vehicle and exposed to all sort of inclement environments) is ridiculous! No clever designer would have chosen this placement.
On 10/13/2015 I took my avalanche to galles chevrolet , albuquerque, nm for repair of a cracked instrument cluster and faulty l/r door lock actuator. I picked it up on 10/15/2015. While parking the truck on 10/17/2015 I shut off the engine and suddenly there was no power to lock the locks with the key fob. It was as if the battery I had had replaced new about 6 weeks prior suddenly went dead. Then I heard a clicking noise in the doors/lock actuators and suddenly the battery power was restored. I next experienced this problem while driving on new mexico hwy 485 on 10/25/2015 only worse. While driving for about 10 miles at speeds of between 35-50 MPH the door lock actuators locked and unlocked the doors numerous times, the airbag, stabilatrac, and ABS sensor alarms kept activating and the cruise control suddenly disengaged many times again while driving. When we reached our destination about 10 minutes later I turned off the ignition and immediately lost battery power and heard the same clicking noises in the doors and needed a hotshot from another driver to get restarted. We were able to drive home in the darkness with all equipment and lights working without further incident. On 10/26/2015 I experienced another incident of sudden sensor and lock activations and alarms while driving in traffic and the hwy. This went on intermittently for about 10 minutes and then stopped. I had the battery, charging system and fault codes checked by a firestone mechanic 2x on 10/26/2015 but no faults were found in the computer and the battery and charging system checked out good. The technician mentioned that the only possible explanation was that the battery or one of the computer modules was somehow losing its ground contact but he checked each of ground contact wires and found each securely connected. I will try to take a video of these events if it occurs again .

- What is wrong
- Certain pickup trucks and sport utility vehicles may experience unwanted antilock brake system (ABS) activation. This condition is more likely to occur in environmentally corrosive areas. This recall will be launched in the "salt belt" states of connecticut, delaware, illinois, indiana, iowa, maryland, massachusetts, maine, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, wisconsin and the district of columbia only.
- Risk
- This can cause increased stopping distances during low-speed brake applications, which could result in a crash.
- Remedy
- Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. The recall began september 22, 2005. Owners may contact chevrolet at 1‑800‑630‑2438 or gmc at 1‑866‑996‑9463.
Recall number 05V379000 · Recall details
Service brakes, hydraulic
- What is wrong
- Certain trucks, sport utility vehicles, and vans equipped with bosch hydro-boost brake assemblies, the hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.
- Risk
- If a separation occurred and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. The presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort and a crash may occur without prior warning.
- Remedy
- Dealers will test the hydro-boost assembly for functional operation of the two-function valve. If the hydro-boost assembly fails the test, dealers will replace the assembly free of charge. The recall began on march 23, 2005. Owners may contact chevrolet at 1‑800‑630‑2438, gmc trucks at 1‑866‑996‑9463 and hummer at 1‑800‑732‑5493.
Recall number 05V043000 · Recall details
Service brakes, hydraulic
- What is wrong
- Certain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of federal motor vehicle safety standard no. 135, ?passenger car brake systems.? Some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore.
- Risk
- Consequently, the valve o-ring seal may fracture. Steering efforts may be slightly increased while braking or parking. Under certain driving conditions, a fractured seal may require a slight increase in the applied brake pedal effort to achieve the same vehicle deceleration rate as prior to the seat fracture.
- Remedy
- Dealers are to replace the hydro-boost relief valve. The recall began on june 18, 2004. Owners should contact cadillac at 1‑866‑982‑2339; chevrolet at 1‑800‑630‑2438; gmc at 1‑866‑996‑9463; or hummer at 1‑866‑486‑6376.
