Thanks for the help. I went and got it checked out and everything still seems to check out. The negative and positive and is good and battery amps are fine and so is the alternator. Maybe the battery is bad and it’s reading wrong could that be a possibility? Or maybe something in the truck is pulling a lot of power like the gauge cluster or something like that?
Hey guys. So just background before I get into what’s wrong with my truck. Couple months ago I bought it and the truck turned off While driving at low speeds and stabilitrak came on and headlights blinked at night. Took it to the dealer and they said they “changed” out the battery but honestly it look used and the same to me. Whatever they did it fixed the issue and the truck has been fine since then. Fast forward now and the truck is turning off while I back up into a parking spot or pull in. Traction control comes on and the steering gets super tight. Every single time I turn the truck off it completely dies and I have to jump start it. Now I thought 100% battery is shot. I took it to advancedautoparts to get it checked out and they said the battery is good voltage is all good everything checks out. They also checked the Alternator and it checks out as well. Anyone have ideas what it could be? Also every time I jump start the truck a message appears saying “open and close driver window”.
Yeah but it’s kind of silly for me to put a new engine in a truck I haven’t even had for 60 days. The stealership I got it from refuses to give me my money back so now I guess I’m stuck with a broken truck that they scammed and sold to me. None of this happened on the test drive that I did before anyone jumps to conclusions. All the problems occurred literally right after I bought it.
So just a little update. I took it to the dealer a couple of weeks ago and they checked the coolant pressure and said nothing was wrong. Checked oil levels and they were fine. Fast forward to now and the truck is still smoking a lot more than before. Now it does it while I drive and doesn’t stop and when I idle it keeps smoking. I have no leaks and no oil or coolant or anything on the ground. I have checked my oil after leaving the truck over night and the level of oil has dropped and is below minimum now. I have no idea what to do any help would be much appreciated.
Okay thanks for the help. The truck has 93,000 miles on it. Should I get the thermostat looked at to see if that’s a problem while I’m at the dealer or just leave it alone?
No not the oil. The smoke coming out of the exhaust is like a gray bluish color. The oil is a golden light color it was changed about 1500 miles ago. I checked the coolant a couple of days ago and it was below the full. Then I checked it recently and it’s not back to full and looking normal. Weird because I didn’t realize coolant fluctuated. Like I said it’s a whole new learning experience with a gmc.
Hey thanks for your replies. I have checked the oil dipstick it does not smell like gas. I have checked the transmission oil as well and it smells a little funny but maybe that’s just how transmission oil smells. By funny I mean the smell of it is very strong. And there isn’t any coolant or anything else anywhere. I was looking at it a little harder and it seems to be like a gray bluish color so maybe it could be the valve covers or a Pcv valve?
Hey guys I’m new on this forum. I’ve never owned a GMC or a truck before and this is a first for me so it’s definitely a learning experience for sure so any help would be much appreciated. It’s a 2014 GMC Sierra 5.3. I recently had the AC condenser line break on it causing it to leak transmission oil everywhere in the bottom half of the engine bay. Got it taken care of. When I received it from the dealer it was still covered in oil residue. I was pretty mad about that but I cleaned it up pretty well with engine degreaser. Then I checked back a couple of days later and there was oil still after I had cleaned it so I took it back to the dealer and they pressure washed it (or so they told me) and now it’s all gone. Anyhow afterwords now everytime I start the truck up and it starts getting warmed up quite a bit of white smoke comes out of the exhaust. It’s pretty common for cars and trucks to do this I know but the smoke smells like burning oil. The truck isn’t leaking oil or coolant on the floor. After I drive and warm up it goes away. But once I park the truck anywhere and start it up again it smokes, I drive a little and it keeps smoking then stops. If I’m stuck in traffic idiling it smokes as well. Any help would be useful please. Could it be a serious problem or still left over old oil residue or just me being paranoid?
