THE VEHICLES: About 30,000 Toyota Camry gas-electric hybrid midsize cars from the 2007 and 2008 model years.
THE PROBLEM: The National Highway Traffic Safety Administration has 59 complaints about intermittent loss of power-brake assist. The agency says it's investigating the problem, which happens without warning. It causes increased stopping distances and requires more pedal pressure to stop the car. Two crashes have been reported but no injuries.
