2012 Chevrolet Silverado 3500 HD Reviews
Bought brand new Silverado 3500 dualie and since new we've had white smoke is coming out from under the hood on passenger side near the windshield when stopping at traffic lights/stop signs. Looks like there's a factory defect with the diesel exhaust fluid leaking and dripping onto the manifold or exhaust pipes which turns into smoke. Just took it into dealer and they said there's a GM service bulletin on the issue and it requires "realignment" of some stuff and "reprogramming" of something. And if that doesn't work, it requires replacement of entire subsystem.
I purchased a Chevy Silverado 3500 HD 1-31-2012. A couple weeks after we got the truck the low coolant message came on the coolant drops two inches from the full mark. We took the truck to the dealer they did a pressure test on it didn’t see any leeks. A week or so later brought the truck back the dealer replaced the coolant tank. We had to take it back AGAIN we had gone through four gallons of coolant! They asked what I wanted done. I said get your GM tech out here and FIX IT! The dealer told me they found the problem coolant was leaking into the number 8 cylinder the dealer said GM had got a batch of bad head gaskets; they replace the head gaskets and all the seals for both heads. A week, week in a half the low coolant message comes on took the truck back to the dealer. GM wanted the dealer to vac and purge the coolant system four times it was just an air bubble. The truck is back in the shop you guessed it low coolant. We ask the dealer to buy back the truck and get us a new one. The dealer refuses to buy back the truck. We are working with GM buy back they have many steps to go through or they are just waiting for me to explode so they won’t have to do anything. Customer Service is dead in America.
