Steering wheel would shimmy while in motion, often accompanied by knocking that is heard and also felt through the steeringwheel while applying brakes, and would stop only when the vehicle came to an near or complete stop. Other notable events include a rough vibration with an audible repetitive thumping that was felt from the left front wheel that would slip on regular intervals while applying brakes. The failure happened suddenly while driving my 2 special needs boys to school. The failure started with little warning in front of the school which is located right off the boulevard. I was able to bring the car safely to a stop due to the 25mph school zone rule. The maximum speed limit is 35 during non school hours and 40 mph further down the boulevard. The power steering became extremely difficult to steer with in seconds before the service (wrench) light came on. I parked my vehicle, and called my insurance company to have my car towed to an reputable care repair shop because the car wasn't safe for me to drive. After 50 minutes the tow truck arrived and when the driver started my car, the car was again steer-able and the maintenance light was no longer on. The mechanics were unsuccessful in reproducing the steering malfunction. September 9th, 2009, the same failure repeated itself, same location same time as before, the maintenance light turned on and then unlike the first event on September 8th, the radio displayed an powersteering failure message on its' screen. The mechanic at the auto shop took a look at my car immediately after he saw the maintenance light, and the powersteering failure message. After the powersteering part from bob stall Chevrolet was delivered, the part was then installed. I paid out of pocket, and didn't find out until after service was rendered, that a discovery was made by the shop while searching for information about my car, that there had been a recall. I never received GM's notice. I have the old part. Part installed is new.

I kept hearing a rattling in my car coming from the front tires area. I took it to my local GM dealership and it was diagnosed as needing a "steering gear". my car is only 2 years old, though it has relatively high mileage. After consulting with others more knowledgeable about cars, I found out that GM has had problems with steering gears in the past, and that my car is definitely too "young" to have that part needing replacement. It's a 2004 Chevy Malibu with 64K+ miles on it.

: the contact stated the steering on the vehicle locks momentarily. This happens without warning. The vehicle has been to the dealership were the vehicle was test driven. The dealership was unable to duplicate the problem. The manufacturer has not been alerted.
