What owners say
4x4 transmission began locking and slipping. Developed a distinctive "clunking" sound when shifting between gears. Now most noticeable between second and third. Additional grinding sound occurs when driving. Noticeable at all speeds.
Tl* the contact owns a 2007 chevrolet avalanche. The contact stated that once the key was inserted in the ignition switch, the vehicle made a grinding noise. The grinding noise continued once the contacts hand was removed away from the ignition key. The contact turned the vehicle off and restarted the vehicle. The vehicle resumed normal operations. The failure recurred several times. The manufacturer was not contacted. There was no diagnostic test completed on the vehicle. The failure mileage was 100,000 and the current mileage was 104,000.
So I was sitting at a red light, everything was cool.. And when I started to accelerate the truck almost felt like we got rear-ended. Then when I tried to accelerate it felt like it had slipped into neutral. Drive is completely dead, when I put itinto drive, I get nothing. So I put it in 1st, and it worked, it went into gear. Then when I started to accelerate it made this horrible scratching/grinding/whining sound. So I can accelerate slowly and switch to 2nd, slowly, and accelerate slowly and switch to 3rd. 3rd feels good when I accelerate but then if I step on it, it slips out of 3rd back to that neutral feeling. If I try to accelerate quickly in 1st and 2nd I get that horrible sound and grinding feel.it is so many people having this same problem over and over. Some say the dealer charge them over $2800 plus to repair others say some dealers fixed the part in the trans called the forward sprag gear and everything was ok. Its crazy that so many people with the same problem. 95 percent of the trucks despite the mileage ( 30, 000 to 93, 000) on her truck did this right after the warranty was up. My truck 07 with only 62, xxx on it trans has now done the same thing as everyone else truck. Someone should force gm to recall these transmission and fix them. Word is they used the same transmission that's in mid size cars and light duty trucks and if so everybody will have issues with a full size truck and a light duty transmission!
I was driving along at 60 MPH and lightly accelerated and heard a clunk. I continued to drive along and slowed down to exit off the interstate. Then when got off the interstate and came up to a green arrow and turned left. Then as soon as I accelerated at 25 MPH, I felt the transmission go out and heard a high pitch whine and some grinding. Then was not able to accelerate anymore.
My 2007 chevrolet avalanche ltz has been in the shop 10x for grinding and squeaking noises coming from the right front wheel. The dealership stated they cannot duplicate this even though their service tech's heard it twice. The brakes have been replaced and the rotors re-surfaced, with the problem beginning @ 22,000 miles and continuing to this day at 44,000. The sound has been caught on video several times at different mileages but gm continues to state that it is not a concern to them. The sound begins slowly as the truck picks up speed it increases and then finally disappears at @ 35mph.
Tl* the contact owns a 2007 chevrolet avalanche. The contact stated that while turning, at a slow speed, the vehicle would grind excessively. The vehicle was taken to the dealer twice but the failure could not be duplicated. The vehicle as not repaired. The failure mileage was approximately 6,000 and the current mileage was approximately 42,000.
When pressing the brake pedal the ABS light comes on. The truck slows but just prior to stopping the ABS feature activates and the brakes make an annoying grinding sound then stops.
Dt: contact stated the brakes had a grinding noise. Contact replaced them on 7-23-05. He pulled the wheel off, and every single brake and rotor was defective. The pads were defective. He took a sledge hammer to get them off. There was inch pad touching the brakes, and that was the only thing stopping the vehicle. Replaced them, and he brought the parts to the dealer, who said there was nothing he could do. Also, called general motors, who indicated that this was normal. The car only had 29,000 miles on it. Contact had a brake problem since he bought the car. There were more pads left on the front brakes, which was uncommon. The brake pads were harder than the rotors. In addition, the rear brakes were defective. The dust covers for the rear brakes were gone . *ak the brakes gave no warning that there was a problem. The emergency brake did not work.
Failure of front cross member beam, excessive noise(popping and grinding)and premature wear. Failure occured at 25000 miles.per chevrolet, the perscribed fix is to install hardened washers and grind and polish friction points. This has been done, yet problem continues. Dealer has told me this is common to the vehicle in question but they can do no more as chevrolet does not have a solution to the problem.

- 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.

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.

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.
