DETROIT (AP) -- In one of the biggest-ever showdowns between an automaker and the government, Chrysler on Tuesday is expected to file papers explaining its refusal to recall 2.7 million older Jeep SUVs that are at risk of catching fire in rear-end collisions.
The government says 51 people have suffered fiery deaths in Jeep Grand Cherokees and Libertys that were hit from behind. Regulators claim that the position of the gas tank, behind the rear axle, makes the Jeeps more susceptible to a fiery crash than similar models.
Chrysler is expected to stick to its contention that the SUVs are as safe as other vehicles on the road from that era. The Jeeps, it says, met all federal safety standards when they were built, some more than two decades ago. Regulators are unfairly holding the vehicles to a new standard for fuel tank strength, Chrysler claims.
Chrysler has successfully used that argument in the past to resist a recall. But that stance carries some substantial financial and public-relations risks.
Car companies rarely spar publicly with the National Highway Traffic Safety Administration, the agency that monitors auto safety. Both sides in the Jeep case say they prefer negotiations, but neither is backing down. Once Chrysler formally rejects the recall, the next step would be for NHTSA to find that the Jeeps are defective and schedule a hearing. Ultimately, though, NHTSA would need a federal court order to impose the recall.
In the meantime, owners of the Jeeps are left in limbo and have to decide themselves if the SUVs are safe enough to transport their families.
The last time an automaker defied a NHTSA recall request was early in 2011, when Ford said that calling back 1.2 million pickup trucks for defective air bags wasn't justified. Ford later agreed to the recall after NHTSA threatened to hold a rare public hearing on the issue.
NHTSA began investigating the SUVs three years ago at the behest of Clarence Ditlow, director of the Center for Auto Safety, an advocacy group.
Earlier this month, the agency sent a letter to Chrysler asking it to voluntarily recall Grand Cherokees from 1993 through 2004 and Libertys from 2002 through 2007. The plastic gas tanks, the government said, can rupture when hit from behind, spilling fuel and causing deadly fires.
Chrysler responded publicly, saying in a statement that it "does not intend to recall the vehicles." The car company's formal response is due Tuesday.
Chrysler Group LLC, which is majority-owned by Italy's Fiat SpA, said the Jeeps are among the safest vehicles of their era.
Chrysler did move the gas tank on the Grand Cherokee in front of the rear axle in 2005, and did the same thing with the Liberty in 2007.
Strengthening the structure around the gas tanks of the older Jeeps, likely the lowest-cost option, would be costly. Relocating them ahead of the axle would cost even more.
Ditlow says the problem could be solved for $100 per vehicle by bolting a metal gas tank shield to the frame, adding a fuel tank check valve to stop leaks and making the tank's hose longer so it won't be pulled from the tank in a crash.
Even that solution would cost Chrysler $270 million, assuming all eligible car owners get the shield, about one-sixth of the company's profit last year.
David Kelly, former acting NHTSA administrator under President George W. Bush, says he expects the matter to be settled before a public hearing takes place.
"Chrysler doesn't want to have a hearing with a bunch of people who have been in crashes and have lost family members," he says.
Kelly expects a lot of posturing before any settlement is reached. Such a settlement could include limiting which vehicles are recalled, he said. "There's a lot of different alternatives," says Kelly.
Chrysler says its review of nearly 30 years of data shows a low number of rear-impact crashes involving fire or a fuel leak in the affected Jeeps. "The rate is similar to comparable vehicles produced and sold during the time in question," the company said in its statement on June 4. It also said NHTSA left some similar vehicles out of its investigation.
But NHTSA found at least 32 rear-impact crashes and fires in Grand Cherokees that caused 44 deaths. It also found at least five rear crashes in Libertys, causing seven deaths. The agency calculated that the older Grand Cherokees and Libertys have fatal crash rates that are about double those of similar vehicles. It compared the Jeeps with the Chevrolet S10 Blazer, Ford Explorer, Toyota 4Runner, Isuzu Rodeo, Isuzu Trooper, Mitsubishi Montero, Suzuki Sidekick and Suzuki XL-7.
