General Motors Corp.'s Saab unit faces a U.S. investigation and potential recall of 119,000 cars after reports of stalling at speeds of at least 40 miles an hour.

The action involves 1999 through 2002 9-5 cars with four- cylinder engines and 2000 through 2002 9-3 sedans, the National Highway Traffic Safety Administration said on its Web site. The agency received 35 reports of stalling because an ignition part failed, including three crashes with no injuries or deaths. Three owners reported smoke and flames coming from under the hood.

Vehicle owners reported that the engine shut down at speeds of between 40 mph and 75 mph and wouldn't restart, the Washington- based agency said today. Alan Alder, a spokesman for Detroit- based GM, didn't immediately comment on the investigation.

The agency began an initial investigation, called a preliminary evaluation. About one in four of those inquiries are raised to a second stage, known as an engineering analysis, and the rest are closed without further action. Seven in 10 of the engineering analyses lead to a recall.

Priceline.com adds search engine

Priceline.com Inc., the Internet travel service, said it added a travel search engine to help consumers comparison-shop for airline fares, hotel rooms and rental cars. The service is being introduced as part of a redesign of Priceline.com's Web site, the Norwalk, Conn.-based company said in a statement Monday. Travelers can also continue to use the company's ''name-your-own'' price offering, in which consumers bid on discounted travel without being told which airline, flight times or hotels they booked until the bid is accepted.

Priceline.com Chief Executive Jeffery Boyd is increasing sales by adding traditional travel agency services. The company said it decided to add the search engine after allowing travelers to comparison shop for airline fares on the site boosted the dollar amount of all travel booked on Priceline.com 52 percent last year.

The company will promote the service with new television ads featuring actor William Shatner. Shatner, best known as Captain James T. Kirk on the ''Star Trek'' television series, first appeared in ads for the company in 1998.
