HOUSTON -

Tens of thousands of Jeeps have been recalled because of a fire danger.

About six weeks ago, Local 2 Investigates revealed an issue with some Jeep Wranglers mysteriously catching fire.

The fires have happened in Houston and across the country.

The federal government has documented 23 unexplained fires over six model years from 2007 to 2012.

More than 67,000 2010 Jeep Wranglers have been recalled in the United States.  

The skid plate in a 2010 Wrangler with an automatic transmission can gather debris and ignite because its near the catalytic converter.

Houstonian Mike Embry watched his 2012 Jeep Wrangler go up in flames about five hours after he bought it. He said his Jeep had never been off road, and it seems unlikely to have accumulated debris in the skid plate.

The 2012 model has not been recalled.

"The damage to Mr. Embry's vehicle was too extensive to determine a cause," a Jeep spokesman said.
