Hi everyone been a while since I posted been a members in the 90s but had to make a new profile anyway I’m having issues with my 2019 2.7 L turbo I have 20,000 miles on it the issue is when it’s below zero outside and you started in the mornings it goes into limp mode I’ve had it in the dealer several times they replace cam sensors cam actuators they even took the wiring harness out and inspected it apparently I’m the only one at this time that’s having this issue and they been  working closely with the GM engineers now other people are starting to have problems got a phone call from my local dealership last week saying now that GM wants my motor so they’re gonna replace my motor with a new one and GM wants my motor to do some tests on it they’re going to stick it in the big freezer hook it up to some monitors and find out what the issue is and then when they figure it out they’re gonna put a service bulletin out my question is has anybody else had this problem needless to say when talking to my salesman I am going to be ordering a 3 L diesel here so in two weeks the truck goes in for a new motor we will see what happens thanks

No they’re going to put a brand new 2.7 L in what I meant is I’m ordering a new diesel pick up because I am not keeping this one since GM won’t buy it back

That's B S.

Tell them they can have the motor if they give you a new truck. Even trade.

You can just swap the gas motor with a diesel?

 

Would be a lot more than just an engine swap. 

 

3.0 is always mated to the 10 speed,

2.7 is never mated to the the 10 speed. 

 

Would also require adding a def tank and fill system.

Emissions and exhaust are different.

Likely different radiator/cooling system. 

etc

 

 

I was wondering if the replacement 2.7L would be the newer high output one....

Pretty sure that's not how warranty works...

GM would have hundreds of thousands of vehicles bought back if warranty worked that way lol

 

Lets see here, $1 billion dollars in used dead trucks or $100 million in warranty work for engines/transmission. Doesn't take a genius to figure out what option they are going to take.

Oh ok, lol. I didn't care for the 2.7l when I test drove one. I got the 5.3, and it has been rock solid this far.

 

Agreed. 2.7l was boring.  Nothing replaces v8's, and if you think otherwise, stop smoking that weed and start realizing its real life

Does the 2.7T have active grill shutters?  If not, I wonder if the dealer or GM even thought about the intercooler freezing up, since the OP mentioned it happens below O degrees F. This has been a problem in the 1.5T found in the newer Equinox/Terrain lineup. The solution there was in some cases an intercooler replacement but in most cases GM just provided those in cold climes a radiator cover to be used during cold weather.

Yes. It has active grill shutters.

I'm thinking about buying the 2019 2.7 leader turbocharged to tow a 2465 Lance almost 30 ft trailer that's only 7 to 8,000 lb when full. Will that be a problem? And I didn't quite understand if you had a gasoline or diesel engine. Diesel is known to be thick in cold conditions. But it sounds like you have a gas so, luckily I live in Texas and we probably won't travel anywhere below zero.

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?

      Tire psi

      By jgaudet99 · Posted

      That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?

      Would this CV Shaft be bad?

      By newdude · Posted

      That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?

      Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
