2008 Buick Enclave CX: Power Steering Failure

June 06, 2008

Yesterday, just as I made the left turn off of California's Highway 33 onto Cerro Noroeste road, our Buick Enclave's power steering began to show the first signs of failure. This is not good. Cerro Noroeste road runs maybe 25 miles through the San Emigdio Mountains and gains probably 2,500 feet in elevation. It's a classic driving road -- one of California's best...

Now I hadn't exactly planned on shredding it in the Buick, but the immanent deterioration of the power steering assist doomed any plans for remotely spirited driving.

The best part? The failure wasn't comprehensive. Around center there remained enough power assist to lure me into a corner with some enthusiasm, only to result in a complete lack of assist once the road began to truly bendand require more steering input. It was a deadly combination that caught me off guard on several occasions. And when the tires weren't rolling, steering was impossible.

There were no leaks and no significant noise from the pump -- just an utter lack of power assist when it was needed most.

We dumped the Enclave at the dealer this morning for a power-steering post mortem. More on this subject later.
