What is this?
Simply put, power-steering fluid is the hydraulic fluid that transmits the power in power steering. Servicing it involves draining or flushing out your car's old power-steering fluid and then adding fresh power steering fluid.
Should I do this service when it's recommended?
Absolutely. The fluid is the cheapest component of your power-steering system. Changing it can help to prolong the life of other, more expensive power-steering components such as the power-steering pump and the stratospherically expensive power-steering rack.
Why do I have to do this?
Over time, the seals, O-rings and internal power-steering components will wear out. When they break apart, they contaminate the power-steering fluid, which forces the power-steering pump to work harder (having to pump little chunks instead of just fluid) and eventually break down.
What happens if I don't do this?
You'll eventually chew up your power-steering pump. It'll have to be replaced at a cost of several hundred dollars, or you'll have no power steering — and you can't easily drive a car that's equipped with power steering when the power-steering system fails. You also may damage the rack, which will require you to take out a small home-equity loan to replace.
Is there any maintenance required between intervals?
If you hear a whining or moaning noise when you turn the steering wheel, you should have your power-steering system checked. Your power-steering pump may be about to fail.
Also, if you notice a leak of any kind, you should definitely check your power-steering fluid level and make sure you keep it topped up. Running out of fluid will cook the pump, too.
Car Talk Tip: If you do a lot of your own car maintenance, and you feel like servicing the power-steering fluid yourself, you'll still need to dispose of the old fluid properly. To find out how to dispose of hazardous materials where you live, check out the 1-800-CleanUp/Earth's 911 Web site.

“It won’t be easy” to take on BMW, said Cadillac General Marketing Manager Don Butler, but if the company has any hope of regaining credibility in the luxury market, General Motors’ flagship brand has no other choice. And it’s not alone.
Last year, the BMW logo adorned more luxury cars than any other brand sold in the U.S., and BMW’s formidable reputation for making its self-proclaimed “ultimate performance machines” establishes it as the king of the hill that virtually every high-end automaker targets, from German rival Mercedes-Benz to Toyota's Lexus.
Time and again, that has proven easier to say than do, and BMW has continued to gain ground in recent years. But it certainly doesn’t mean competitors are backing down. Audi, for instance, is making inroads with products that deliver a mix of solid handling and acceleration along with eye-catching design. Akio Toyoda, president of Toyota, Lexus' parent company, has vowed to put more “passion” and “performance” into new and redesigned products like the LS 460 sedan that will go on sale later this year.
“I would not tell you the truth if I said I did not care” about the challenge the competition is presenting, said Ludwig Willisch, who last year became the CEO of BMW of North America. He added he's also intent on maintaining the position BMW gained in 2011 as the U.S. market’s luxury sales leader.
Being No. 1 “is meaningful to us,” said the German executive, and not just when compared to the likes of Cadillac, Mercedes or Lexus. Though BMW was the luxury sales leader in the U.S. in 2011, China surged to become BMW’s top market. As of June, however, the U.S. is back in the lead — although BMW of North America is now in a tight race with Mercedes-Benz. And after seeing its sales collapse in 2011 as a result of product shortages stemming from Japan’s March earthquake and tsunami, Lexus is now back in the competition, as well.
BMW has rolled out a number of new models in recent months, including an all-new 3-Series, several high-performance M models, the new X1 compact crossover and, for 2013, it will update its flagship 7-Series.
The new X1 targets a fast-emerging compact crossover segment that Willisch anticipates will bring “new customers we haven’t seen so far.”
Collectively, the German luxury automakers have launched what is considered to be the most aggressive era of product proliferation in automotive history. As soon as some product gaps are identified, BMW or Mercedes or Audi rapidly jumps in — usually with the Teutonic competition quickly following.
“It’s all about entrepreneurial spirit,” said Willisch, who downplayed concerns that BMW is overdoing things. A few years ago, the automaker saw skeptics abound when it rolled out the X6 Sport-Activity Vehicle, a crossover blending attributes of a conventional SUV and a sports coupe. But demand has been strong enough to persuade the maker to prepare a smaller version, the soon-to-launch X4.
He has a point. Skeptics dub such miniluxury models as “compliance cars,” which luxury makers like BMW and Mercedes-Benz have to add to their lines in order to meet strict new U.S. mileage mandates and toughened European carbon dioxide rules. Lexus, Cadillac and Audi can turn to down-market sibling brands, such as Toyota, Chevrolet and Volkswagen.
Indeed, while BMW is rolling out a number of new battery-powered cars and plug-in hybrids, such as the new 3-Series-based ActiveE and the upcoming i3 and i8 models, Willisch acknowledged they’re likely to generate collective volumes “in the four digits.”
More conventional hybrids, such as the revised 2013 7-Series version, could do better. A recent study found that the Toyota Prius is frequently found as a companion to luxury models like the 7-Series in the 10 most affluent ZIP codes in America. Willisch said more and more luxury buyers, regardless of their income and net wealth, “are interested in fuel economy,” even if they're just driving something they can brag about to friends and neighbors.
Last year’s strong showing by BMW in China makes it clear that the automaker will have to adapt to global realities. BMW is developing new products specifically for China, notably a stretched version of the 3-Series designed to appeal to buyers who prefer being chauffeured. But no worries, insisted Willisch. He said his company “will continue to build ‘truthful’ BMWs” that can live up to the ultimate driving machine image.
But expect the manufacturer to also put more emphasis on design, creature comfort and safety, as well as quality and customer service. If competitors like Cadillac want to take a shot at BMW, the Bavarians are more than ready to return fire.
