DETROIT (AP) - Chrysler is expected to file papers Tuesday explaining its refusal to recall 2.7 million older Jeep SUVs.

The U.S. government asked Chrysler earlier this month to recall Grand Cherokees and Libertys because the position of the fuel tank leaves it susceptible to rupture in a rear-end crash. The ruptured tank can spill gasoline, which can ignite if an ignition source is present.

The agency says 51 people have been killed in accidents involving the older Jeeps.

But on June 4, Chrysler publicly rejected the recall, saying the Jeeps are safe and the government is creating a new standard for gas tank strength. Tuesday is the deadline for Chrysler to file its formal response to the government's request.

Chrysler is freezing contributions to its U.S. defined benefit pension plans for salaried employees, and will switch to a defined contribution plan instead.

Chrysler will determine the amount it will contribute - and that amount is not being publicly disclosed - and employees will choose from a number of investment strategies, such as stocks and bonds, annuities, etc.

When you look at much of popular media these days, it often feels as though the advertisers of America are eyeing that young audience. If you're over 55, you could certainly be forgiven for getting the idea that advertisers and agencies don't much care what you want to buy.

Well, a new study by the University of Michigan Transportation Research Institute proves that, at least when it comes to buying cars, it's those often overlooked, sometimes-invisible over 55's who are doing much of the buying.

The study found the 55-to-64 year old baby-boomers are 15 times more likely to buy a new car or truck than the 18-to-24 year olds.

John Wolkonowicz, an independent auto analyst, joined us from Boston today to talk more about why baby boomers seem to hold the key to success for automakers.
