DETROIT — U.S. safety regulators have expanded an investigation into Jeep Wrangler fires.
The National Highway Traffic Safety Administration is asking Chrysler for information about Wranglers from 2007 through 2012. That is an expansion of a probe that began March 28, and focused on vehicles from the 2010 model year.
Chrysler makes Jeeps and sold more than 532,000 Wranglers from 2007 through March.
The government says 23 Wrangler owners have complained about fires. Complaints say four people were hurt and two houses were damaged. Three of the injuries were minor burns.
Chrysler had no comment on the expanded probe Wednesday. It has said the Wrangler meets or exceeds all safety standards and has an excellent safety record.
An investigation can lead to a recall.
