Is it just mine?

I have only driven the truck a half dozen times but when I turn the key to start it, the key stays in the start position (by itself) until the engine starts, then releases (by itself)

 

Is this something new or is it my first defect?

You just have to turn it and let it go. It cranks and starts itself. Had this on my 2014 and 2015 and now on my 2016.

After almost 2 years I haven't noticed this, but I also keep it in the start position until it starts. I'll have to try this tomorrow.

 

By the way, why do you say "first defect"? Makes it sound like you bought the truck knowing it will give you problems yet you bought it anyways. Really no need to feel negative about the truck unless it's actually giving you problems. You also can't go by the % of people and comments on a forum. A lot of negative questions will be from someone joining because they have a problem, not because they're truck hasn't given them any problems and want to tell everybody. I've had my truck since very late April of '14 and has a little over 23,500 miles with 0 problems or issues.

+1... GM must be one powerful brand... How great for them..... Think about it, the buyers are convinced before hand the trucks are junk, but still buy them! lol...

 

In all seriousness.. remember there are millions of these trucks on the road now. The big big majority don't have any major issues.

Ya that's what people need to realize is that no matter how many on a forum are having problems that's not a good measuring stick to what % of these trucks have problems. Most isn't on forums and with how many of these trucks are on the road it's easily a small fraction of 1% that actually give any problems.

Tried mine and it does it. Never noticed since I just hold the key in the start position until it starts. I guess that's "old school" now. I'm thinking it has something to do with the remote start system or maybe it has nothing to do with it at all.

Speaking of Ignition my brother has a 2015 Silverado Lt and when you turn the ignition key to run(but don't actually start the vehicle) then turn the key to the off position the truck engine turns over and then shuts off. He says he as a friend that has the same situation happen. He asked me to try it on my 15 gmc sierra denali and mine does not do it. Has anyone here seen or heard about issues like this?? Anyone know a potential cause?

Haven't heard of that problem before. There's been many times where I've been waiting in my truck and after the 10 minutes the radio and everything cuts off so I turn the key to the run position to turn the radio back on. Never had it start unless I turn the key all the way to the start position or do a remote start.

Well I know there is an accessories key turn and then a run key turn then the final turn before the motor turns over. He is going past the accessories function to the run function but never turns the truck over. In that setting you can hear the fuel pump run charging the line but he never bumps the key to turn the motor over. Then when he goes and turns the key to the off position the motor turns on and then shuts right off. He has talked with a service writer at our local dealership and has not heard anything back but has not actually taken the truck in to have it looked at.

My key does not stay in position. Itll go back to the Run position soon as I let go however the starter will continue to turn over til it starts.

 

OP is saying the key physically stays in Start position til it starts then goes back to Run on its own? Interesting...

Not a defect, GM trucks and other vehicles have done this since 2007 I think. The key doesn't actually stay in the Start position, it returns to Run but the start signal is sent to the engine and it controls the starter motor by itself. I have gotten so used to just flicking the key over for starting my truck that I have to think twice about it when getting into my other vehicles...

My 2003 Yukon "self" starts as well. But neither they Yukon or my 2015 truck keep the key in start. As other posters said, it returns to Run when released but the starter keeps cranking.

Are you saying the key stays in the start position until running OR the key returns to run position but the truck continues to crank until it starts?

 

When you release the key it should spring return from 'start' to 'run'.

 

With these trucks, the key sends a start command to the ECM. ECM manages the start -- signal to run starter. decision when to fire injectors and spark.

 

If you key returns and the start function continues, it's working correctly.

I turn the key to start and let go. It stays in the start position until the engine starts (maybe only a second or two) and then it returns to run by itself after the engine starts

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Z45 · Posted

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
