WASHINGTON, D.C. -

The National Highway Traffic Safety Administration indicated that General Motors is expanding a recall of SUVs first included in a campaign last August.

This time, the automaker is recalling a total of 193,652 units, models that include:

—2006 Chevrolet Trailblazer EXT
—2006 GMC Envoy XL
—2006–2007 Chevrolet Trailblazer
—2006–2007 GMC Envoy
—2006–2007 Buick Rainier
—2006–2007 Saab 9-7x
—2006–2007 Isuzu Ascender

NHTSA explained that fluid may enter the driver’s door module, causing corrosion that could result in a short in the circuit board.

“A short may cause the power door lock and power window switches to function intermittently or become inoperative,” regulators said. “The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.

“A short in the circuit board could lead to a fire, increasing the risk of personal injury,” NHTSA went on to say. “A fire could occur even while the vehicle is not in use.

As a precaution, NHTSA mentioned that owners are advised to park outside until the remedy has been made.

The agency noted that owners will be contacted and dealers will test the driver’s door module.

If the module is functioning properly, a protective coating will be applied.

If the module is not functioning properly, it will be replaced.

These repairs will be done free of charge.

GM will notify Buick, Chevrolet, and GMC owners, Isuzu and Saab will contact their respective owners, beginning July 24.

Owners of these units also can call the respective brand owner center:

—Buick at (800) 521-7300

—GMC at (866) 996-9463
