Problem: On certain passenger vehicles, a combination of throttle positioning sensor irregularities, a dirty throttle housing, and/or inefficient software calibration may cause a warning lamp to light and the subsequent onset of limp home modes.
Risk: This resulted in a high number of vehicles going into the limp home mode without need.
Remedy: Dealers will install the current software upgrade onto the involved vehicles. The recall began on december 29, 2006. Owners may contact volvo at 1-800-458-1552.
