I just bought my 2008 Solstice with only 30,000 miles! It rides like a dream. However, I need a bit of guidance. The remote doesn't work and neither does the tire pressure indicator. Took it the Pontiac dealer and said they would have to replace the module for $2,000. But I read somewhere that if you leave the Solstice without a battery connection for a while, the sensor looses connectivity with remote and tire pressure. Is there another remedy for this? Not paying 2K for repairs.
