Hi, I'm new to the forums, i bought my GMC back in April and now have around 2500 miles on it, didn't have any problems so far but today i remote started it and saw a lot of white smoke coming from the exhaust. All the fluids seem fine and it runs good, not sure if i should take it the dealership or just keep driving it.

  That is the oil pump catching a prime. They have been doing that for years.The TSB is 14-06-04-004I. The document ID is 7100140. Maybe someone who is more computer savy can figure out how to upload it here. I only fix them.

  It's not going to be a high mileage truck. I'm 62. My 2014 only had 55k on It. It probably won't see any towing. If so, it would be pretty light. Maybe a snowmobile or a small boat. For grins and hahas I went out with my TPMS recal device. Despite there being nothing in my 2026 owners manual about a manual TPMS relearn mode, according to the internet it did exist. Sure enough it came up even with a down level DIC. I gave programming the first tire a shot. As expected, it didn't work, but I had to try. Waiting for a tracking number on the new sensors

  Meaning the manufacture of the catch can. They are completely unnecessary.
