99 Tahoe has problems turning on
SAN MATEO, CALIFORNIA -- I have had my tahoe 1 and 1/2 years. For the last 6 months my car has moments that it will not turn on. Sometimes it turns on fine, but others it turns, but won't start the engine. I have taken it in to several places, including a Chevy dealer, with no results. Does anyone know what is wrong with this car???
