WASHINGTON (AP) - The government has opened preliminary investigations into electrical issues in the 2006 Honda CR-V and potential shifting problems in the 2007 Kia Optima.

The National Highway Traffic Safety Administration says the Honda CR-V probe covers about 150,000 vehicles. Three owners complained of fires in the driver's door coming from the driver's power window switch.

The Kia investigation covers 41,000 vehicles. Three consumers complained that a shift cable in the automatic transmission could detach from the shifter, preventing the transmission gear shifter from working properly. One consumer complained that the car rolled away after it was parked.

In some cases, vehicle investigations can lead to recalls.
