The contact owns a 2002 Chevrolet Avalanche. The contact stated while attempting to stop the vehicle, the brake pedal was firm, and vehicle kept accelerating unintendedly. Several warning lights were illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the failure was due to a faulty abs module. The vehicle had not been repaired. The manufacturer was made aware of the failure and determined that the vehicle was not included in a recall because he was not located in a salt state. The failure mileage was unknown.

Vehicle sometimes without warning, would shut down. Yes its available for inspection. Its unsafe because of the element of surprise when suddenly finding out that the ability to control the vehicle is dangerously compromised. Specifically when trying to steer or brake effectively or even trying to get to a safe location. With no warning there is not much time to react to the situation. In spite of having a perfect driver score I become a threat to other drivers and pedestrians when my vehicle shuts down. I have had it looked at by two different local mechanics. After trying a few less expensive options its becoming more evident that its a faulty sensor. After checking to see about other owners with similar issues, I have learned that the crankshaft position sensor was often behind the problem. This is not to say, it is in my case. My point is that with it posing a safety risk why should these other owners and im sure more to come and me have to respond after possibly being in a deadly accident when this has been a documented as an ongoing problem. As for the rest of the questions, no one other than a mechanic has looked at the vehicle. Some times there would be an indication message on the dash along with engine trouble light and nothing would happen. But most recently it twice shut down without any indicator message. Once was on the highway the other about two hundred yards before a railroad crossing.

I went to stop my 2002 chevy Avalanche 1500 and the pedal started to pulsate like my brake assist was gone as I nearly rear end a vehicle and had to swerve out of the way do to the brakes not wanting to stop the vehicle as there supposed to normally. The truck has a p0265 code which is a fault in the ecbm do to the solder joint on the relay in the board. I'm a mechanic for a living and I cant believe this recall still hasn't been addressed a long time ago! this needs to be looked into ASAP and its not just the 2002 Avalanche. All these vehicle's listed have this issues but instead of recalling the ebcm for the solder issues they decide to recall it for corrosion on the wheel speed sensors big mistake that still to this day needs to be addressed. 2002-2006 Cadillac escalade, ext & esv 1999-2007 Chevrolet silverado 2000-2006 Chevrolet suburban, tahoe 2002-2006 Chevrolet Avalanche 2002-2007 Chevrolet trailblazer & ext 2003-2006 chevolet ssr 1999-2007 GMC sierra 2000-2006 GMC yukon / denali / xl 2002-2007 GMC envoy / xl 2004-2005 GMC envoy xuv.

Stopping, from between 5 and 10 mph, after a small drive - like a few yards. . The anti-lock brake engaged, made a pulsing / ratcheting noise and the brake pedal vibrated -- but the truck did not stop. I could not press down on the pedal any harder, and the truck took substantial distance to come to a stop. --dry road. -- I also have an abs light on the dash from time to time.

The contact owns a 2004 Chevrolet Avalanche. The contact stated that upon starting the vehicle, the brake warning light illuminated. The vehicle was taken to an independent mechanic who diagnosed that the rear brakes needed to be replaced. The contact stated that the vehicle was repaired however, the failure reoccurred while driving. The vehicle was taken to another independent mechanic who replaced the parking brakes and the brake fluid; however, the failure persisted. The contact stated that the brake pedal would hesitate to respond when depressed, causing a 100-feet in stopping distance delay. The dealer was notified of the failure and informed the contact that the vehicle could not be repaired under NHTSA campaign number: 04v045000 (service brakes, hydraulic) since the VIN was not included in the recall. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 178,000.

Vehicle looses power and brakes go out then dies,doesn't matter speed. If slowing down and press the brakes, the locks, lights, and security goes crazy. This is dangerous as it is in intersections and caution for collision. The vehicle has to be off for a time frame and restarts fine and can go. Happened when coming from ramp and in middle of road with semi truck coming down by us.

In October of 2020, my Avalanche only would start in winter after disconnecting and reconnecting the battery. It was also on numerous occasions go into limp mode while driving at normal city speeds meaning it wouldn’t go above 25 miles an hour. The entire dash would light up. It threw numerous codes. Had to be towed to get it looked at but then would mysteriously start without issue. I took it to young Buick GMC in layton utah with no resolution. Finally in December 2020 it was determined by now heritage Chevrolet in evanston wyoming to be the onstar module. This part was no longer available and couldn’t be replaced. The dealership’s solution was to wire around the faulty part which has allowed the truck to start and no longer go into limp mode from 70mph on highway to 20mph without notice. I immediately got a hold of Chevrolet to get a satisfactory answer about why I couldn’t get the part that was making the vehicle unsafe to drive. They said the part was no longer being manufactured and it wasn’t their problem sorry about the inconvenience case number [xxx]. I did have the dealership wire around it so I have the truck working, but Chevrolet did not care about the truck going into limp mode suddenly on the highway and it could have caused an accident. They not not offer any compensation for the part not being manufactured and according to to your website if a part is causing a safety issue they are they are required to have that part fixed. I am still upset about their lack of support and service and want Chevrolet held accountable. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car crash and braks locked air bags didnt deploy, injuries left unpaid and vehicle damages.

Driving 60mph and lost all lights power motor everything the vehicle came back on and repeated this over and over till it was parked gm's said my truck wasn't covered so I asked for the recalled part number and was rushed off the phone.

After washing my 2007 Avalanche the seatbelt on the passenger side exploded and my brakes started to fluctuate and make a spring noise. This all happened as I drove away from the car wash.

So the hydraboost is failing and my truck is pouring an insane amount of power steering fluid from hydraboost system. When researching this problem for my year make and model the hydraboost recall pops up but when calling Chevrolet they want to do nothing. When its apparent my truck is affected by trash parts. It only has 149000 miles on it and the hydraboost system is gone. I'm tired of adding 2 quarts of power steering fluid a week, and cant even drive my family around because I waiting on brakes to sporadically fail due to the system being compromised.

1. Vehicle stabilitrak light comes on, all the dash board lights goes on and off, the needles are going wild and then nothing. The vehicle still drives normal. 2. The clock will not keep regular time even when reset many times. 3. The drives side rear speaker will not come on. 4. When using cruise control the vehicle accelerated quickly causing me to think it was out of control, this happen once.

The abs system engages at low speeds when stopping on dry pavement. Generally the condition is limited to speeds under 10 mph when parking or stopping at stop signs. This condition disengaged the breaks and caused the vehicle to move beyond the traffic control signal at a four way intersection, nearly resulting in a serious side impact collision.

Brake lines rusted out. Apparently this is an issue for this year and many other model year vehicles. Considering the brakes stop the vehicle, this is a big safety issue, and very expensive to be fixed.

When nearing a stop light at est. 15 mph I stepped on the brake and it was like stepping on a rock. The pedal did not move. I pounded on the pedal and finally had enough brake to stop. There were no warning lights. Afterwards the brakes were good. This was repeated twice more. I took it to a brake shop where they checked all mechanical function and found nothing wrong. They hooked up the computer and found no codes. I took it to a Chevrolet dealer and they could not find any codes. During a test drive the mechanic unhooked the vacuum line and had no vacuum. He found the motor was making vacuum. Back at the shop he said it was probably the vacuum booster. When it was replaced the brakes worked as they always had except when they didn't work. Now that the booster has been replaced I do not know if the problem is fixed since it is a random problem. I will not be able to trust the brakes until at least a month goes by with no problems. The truck has less than 29000 miles on it.

My vehicle speed appears to be fluctuating, engine braking also occurs when the service stabilitrak lights come one. I was driving and it felt like it stalled or the clutch kicked in then reengaged. Online forums depict hundreds of owners with the same incidents. The issue affects many components of the vehicle. Some believe that the onstar system or the abs module is defective. This is a serious problem that must be investigated. When I took it in last time, the dealer claimed it was a faulty abs sensor. This did not solve the issue as this continues to happen off and on and I fell this puts us at risk. These issues happen while parked, driving, and turning, be it roadways, driveways, parking lots, etc.

Brakes went out with no warning, two different times. On a highway stopping for a red light.

See all problems of the 2003 Chevrolet Avalanche 🔎.

When driving my Avalanche on a highway, as I approached a red light, I pushed my brake and it went to the floor board. I pumped my brakes to stop and I felt a pulsation as I pushed the brake pedal again and I could brake. This happens intermittantly. I have seen complaints about this on the internet. It should be investigated because Chevrolet wants me to pay for this problem.

Tl-the contact owns a 2004 Chevrolet Avalanche 1500. The contact stated that when the vehicle was turned off fuel leaked from the fuel lines and fumes emitted into the interior of the vehicle. The contact also stated that the abs warning lamp flashed and the brake pedal became extremely difficult to depress. The contact also stated that the seat belts failed to operate correctly to secure and retract. The vehicle was taken to an independent facility to be diagnosed for the failure. The contact was informed that the fuel pump modular assembly, module kit and fuel tank needed to be replaced. The vehicle was not included in NHTSA campaign number: 06e043000 (fuel system, gasoline), 05v163000 (seat belts), 05v043000 (service brakes, hydraulic). The manufacturer was notified of the failure. The approximate failure mileage was 144,000. Ah.

The contact owns a 2011 Chevrolet Avalanche. While the vehicle idled, the stablilitrac and abs warning indicators flickered. The vehicle was taken to the dealer, but they could not duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 93,778.

The blower stopped working on my auto temp control and now won't shut off.

Driving home the breaks went to floor when stopping. Break fluid was everywhere. Front break line broke. All break lines extremely rusty and need replaced. Live in north carolina very little salt on roads.

At low speeds the anti lock brakes engage on dry pavement. . This greatly increases stopping distance.

I was coming down the hill and saw 2 vehiles stopped one was going to turn once traffic was clear. And I started slowing down almost to a stop on a hill and I got about 2 car lenghts away still stepping on my breaks and all the sudden my break light came on. A warning came up and said service break system when I slambed into the rear end of the car in front of me who intern hit the car infront of them. I had just replaced my breaks and roters 45 days before this. I blew the breakline on the front. July 2012 I blew a breakline. Noone was injured that time and also blew a break line August 2013. So for the 3 time blowing a breakline there is something wrong. I lived in the north carolina until moving to west virginia in 2012 and this has happen every year since I moved north.

Lost complete power of car. Could not steer, or brake. Happened in snow. Since that time it has happened 5 other times. 3 in the last week with the snow and rain. There is a great potential for loss of life. Have researched this for months and there are many Avalanche owner with the same problem.

The contact owns a 2002 Chevrolet Avalanche. The contact stated that while driving approximately 5 mph, the brake pedal was depressed and the abs engaged without warning. The vehicle was not diagnosed or repaired. There was a recall related to the failure under NHTSA campaign id number 05v379000 (service brakes, hydraulic) and the contact's VIN was included in the recall however, the contact's state was not mentioned as one of the salt belt states that were eligible for repairs under the recall. The manufacturer was notified of the failure. The approximate failure mileage was 180,000.

There is an issue with moisture. First incident occurred in snow. Traveling around 55 mph when I hit a patch of snow on the road and the truck stalled. At that time, I also lost steering ability and braking ability. Truck would not start. Towed to mechanic. Real issue never found. Basically dried out and started again (2) days. Second incident happened during rain. Went through a small puddle at 40 mph and had the same issue. Towed again and started right up the next day. Third incident happened last night, April 25, 2013 while driving home in a driving rain storm. Did not hit any water just stalled on it's own. Again, stalled and would not start. Towed for a third time. Talked to Chevrolet this morning they said there were no recalls for the issue but I have checked online on several different forums and it seem to be a problem for many folks.

Vehicle was moving at approximately 50 miles per hour and brakes were applied to prepare for a right turn. At first the brakes were beginning to be effective, but sudden loss of hydrological pressure resulted in brake pedal traveling all the way to the floor and little to no braking power was available. Indicator lights and bells illuminated indicating that the braking system needed serviced. Vehicle coasted to a stop and was placed into park. Brake fluid was visible on the passenger side front wheel well.

Sitting at red light all of a sudden brakes seemed to let go car started to roll back a bit had to push brake pedal to the floor.

A guy pulled out in front of me and I almost t boned him if he didn't get out of the way, since I didn't get it stopped for another 40 yards past were the accident would have happened. After further inspection the break line exploded causing loss of break peddle pressure. All of the break lines, especially in the back, are rotted and scaling, and rotor splash guards have rotted away completely. I'm sure gm will point to mileage as a excuse, but there really isn't any rust on or under the except on the break lines and my none existent splash guards. I drive 600 high way miles a week and expect normal pad/rotor/bearing wear and tear but this is clearly a faulty part.

Applied brakes, pedal went to the floor - truck could not stop - ran into bushes on side of road.

I was driving at a speed of 50 mph approaching stopped traffic, when I applied the breaks, the break peddle went to the floor and the vehicle do not slow down. The break light came and and I applied the emergency break to slow to a stop. I then had the vehicle towed to a repair shop where they told me that all four of the break linings were rusted through. I hunt and fish with this vehicle and go off road a lot, this is why I purchased this vehicle in the first place. To have a off road vehicle manufactured with break linings that rust through is criminal.

When applying the brake to shift from park the brake pedal goes to the floor. This happened in July and November 2013, and again about two weeks ago.

Driving on the highway at 50 mph applied brakes to stop at traffic light and pedal went to the floor. I had no brakes, pulled over to the side of the road and after examination saw brake fluid under truck.
