Right now Chrysler is really in trouble. Reports have surfaced about a safety defect in older model Jeeps — the Jeep Grand Cherokee from 1993 to 2004, and the Jeep Liberty from 2002 to 2007.

According to the National Highway Traffic Safety Administration, the Jeeps allegedly have defective fuel tanks, which can be damaged in the case of a crash and erupt into flames. The tanks are located in a particularly vulnerable place – just behind the rear axle and below the bumper – that make them a serious fire hazard.

Fires from these sorts of accidents have allegedly killed anywhere from 50 to hundreds of people. The real impact is still unknown.

But while the government and many consumer advocates have called on Chrysler to issue a recall of nearly 3 million vehicles – what would be one of the largest vehicle recalls in history – the company has so far refused.

Chrysler says they stand by the safety of their vehicles despite the government’s 3-year investigation into the fire hazard issues. They don’t agree with the findings and think the problem has been overblown.

You can learn more from this ABC News report. There is also a popular petition on Change.org demanding the recall.
