While pulling into a parking space the brakes lost all power assist and the brake pedal was completely stiff. I had to press the brake pedal extremely hard to prevent hitting the car parked in front of me. I was moving slowly and this condition came without warning. Moments earlier the brakes had performed normally. This vehicle has 44,000 miles.

The brakes don't hold at times. Has happened while backing up and during regular driving conditions. It has only happened during city streets or during stop and go driving. Feels like my brakes never engage but the pedal is pressed fully.

Ts bulletin no.: pit5361B brakes lose vacuum at low speed (eg. Stop/start traffic, fast food drive through lanes). It's as if the engine was turned off while braking. Chevrolet charged $645 to replace vacuum pump.

Was going down a steep hill in Kentucky in stop and go traffic and without warning the brake pedal got really hard to push and the truck didn't want to stop. Also happened at a low RPM going down the approach of a driveway. I am able to duplicate it. Also at red lights if I pump the brakes they become really hard to push.

- Warren, MI, USA

The brakes fail(periodically) at low RPM due to vacuum booster pump failure. Typically happens when moving slowly at idle - rolling down a driveway etc.

I am having brake assist failure at all speeds. It is impossible to stop without applying full force. The ABS 'clicking' can be heard and felt while trying to apply brakes. This system failed going down a mountain pass with a camper behind us and children in the back seat. The 'service brake assist' light was displayed.

I'm having brake booster failure at slow speeds, the brake petal is super hard to push down and it almost isn't enough to make the truck stop rolling at slow speeds. Truck has right at 43, xxx miles on it and is not under warranty.

At 4200 miles the front right disc brake was damaged beyond repair. The mechanic stated that the front left showed normal wear and that it still have more than 50% left on the pad. The right front caliper was not retracting and caused the brake to run compressed for a long time hence causing unrepairable damage to the rotor. The dealer service did not inform me of the defective caliper, only that they needed to replace the rotor and brakes, never mentioned that the left side was normal. Is there a recall for brake calipers on this vehicle??

Upon accelerating after traffic light, power fails, steering locks following grinding clanking sound in steering column. Also occurs same symptoms in attempt to move gear shift to park position. More frequent doing this procedure. Key moves by itself to originally input position in process of locking steering. This defect occurred eight times within five days, requiring towing, and being stranded. Vehicle delivered by tow service to nearest Chevy dealer on first few failures, vehicle returned to original dealer 230 miles away near owners home at cost of owner. Original dealer believes defect is potentially lignition locking system, attempting to verify at this period. This major safety issue of loosing power and systems locking up jeopardize occupants and others lives.again occurrences were at very low speed or in motion of parking.

While in motion in city at intersection, stopped for light, proceeded forward but steering locked, brakes, and ignition switch inactive, a grinding clicking noise heard just as began accelerating before safety failure. Truck towed to a dealer, unable to determine cause, released truck, problem occurred again in three days causing vehicle to be towed again. Mechanic unsure, no errors codes, however sounded similar to early recall by GM for ignition switch torque problems, but noise could be per mechanic something in rack and pinion or rotary vene pump. Dealer not committing and suggest to drive. Safety for lives is concern in this matter with lack of electrical, steering, brakes, and ignition control by driver.

My truck came with an optional $770 trailering package including auto locking 3.42 ratio rear end, 5.3 litre V-8. the sales pitch is I can now tow 9800 pounds. They don't tell you that there are no trailer brakes! so how am I supposed to stop when I'm towing 9800 lbs? I contacted GM and they gave me a claim # 8-2253662923 and told me that I would hear from them within 48 hours, 4 days later I called again and was told that a supervisor needed to talk to me, she told me that she would contact the dealer nd someone will get back to me, that was 2 weeks ago. I think that this is an extremely unsafe condition, this will kill people! any help would be greatly appreciated.
