Feds investigating Solstice GXP, Sky Redline brakes

The National Highway Traffic Safety Administration ( NHTSA) has received around 40 complaints from owners of the Pontiac Solstice GXP and Saturn Sky Redline regarding the vehicle's braking performance. According to the owners, too much pedal effort is required to slow the vehicle down when the engine is cold. This may correlate with a TSB issued by General Motors back in December that advised dealers to recalibrate the braking control computer on both models. The system uses the stability control module's pump to increase hydraulic pressure when engine vacuum is low.

The investigation is in its preliminary stages, so no recall is in effect yet. However, NHTSA has one case of a crash involving one of the two models that could be attributed to the problem.
