GMC Sierra C3 Reviews
Low beam headlamps not working. Replaced bulbs and checked fuses. Any suggestions?
The aerodynamic headlights do not proved much light when doing night traveling. The 6.0 V8 engine always has 'piston slap' upon cold-starts making the vehicle sound like a diesel engine. Truck is very reliable and loaded with too many options to discuss. I would buy it all over again if given the chance.
