The National Highway Traffic Safety Administration (NHTSA) is gearing up to put pressure on Fiat Chrysler, demanding that the company to step up the pace of repairing Jeeps covered by a recall for fuel tank issues.

The announcement came yesterday from NHTSA Administrator Mark Rosekind. He said action could come as quickly as a couple of weeks.

Rosekind's remarks were a follow-up to comments he made earlier this month at the New York International Auto Show. (See "NHTSA may reopen Jeep recall investigation" ).  According to Rosekind, two groups within the agency have developed what he called “range of options” for possible actions.

Rosekind declined to offer any specifics about the options under consideration but they could include reopening the investigation into the fuel tank problem.

Fiat Chrysler is not the only one on the NHTSA hot seat. Rosekind said options are being developed to accelerate repairs of millions of vehicles recalled due to defective Takata airbags.
