I have a 2003 Honda Civic, 140,000 miles. I have been experiencing a temporary loss of power steering when slowing down (I usually notice it while applying the brakes and making a turn). When I let off the brakes, the power steering usually comes right back on. This does not happen all the time, maybe once or twice a week. I brought the car to my mechanic and explained the problem. They asked if it happened in wet weather... we have had a lot of wet weather lately, but it has happened on very dry days too. They checked it out and couldn't find any problems or reproduce the effect. The problem has come up a few times since then. Any ideas about what's going on? Are there any possible problems that could have been overlooked by my mechanic's inspection?
