So this just happened to me. Fixed itself in 24 hours but still had me upset. It’s still a brand new truck. So hopefully this doesn’t happen again. Any suggestions to keep it from happening again?  A fuse change?

You'll have to contact the dealership to see why the check engine light came on. You have a warranty after all on a new truck.

Take it in and see if they can find the computer has stored the cause of the CEL.

Go to dealer to get reason for code.  

 

FYI--low fuel (warning light on) also will not allow a remote start.  I know this isn't your problem but just wanted to share/add.

I haven't tried remote start with low fuel.

 

The OM warns against using remote start if fuel is low --- but doesn't include low fuel in the list of things that prevent remote start. 

 

 

2021 Manual:

 

Do not use remote start if the vehicle is low  on fuel. The vehicle may run out of fuel.

 

The vehicle cannot be remote started if:
. The RKE transmitter is inside the vehicle or if the key is in the ignition.
. The hood is not closed.
. There is an emission control system malfunction and the lamp is on.
. The ignition is in any mode other than off.
. The hazard warning flashers are on.
. Two remote starts or a remote start with an extension have been used.
. The vehicle is not in P (Park).

 

The engine will turn off during a remote vehicle start if:
. The coolant temperature gets too high.
. The oil pressure gets low.

I could be thinking of my last truck. I’ll try it next time my fuel light is on.

My truck ended up being able to remote start with low fuel (2020 Trailboss w/ 6.2) so I must of been remembering my Ram.  I would assume that my 2021 Sierra is the same.

Low vehicle battery charge?   Will it affect/disable remote start.   Have a 2019 Silverado Z71.   Key fob batteries are brand new.   Dealership telling me the hood latch may be defective.   I have a hard time believing it would be bad in 3 years.

 

I have code reader and no codes stored to prevent  a remote start.   When I open and close the hood with the code reader hooked up it immediately reports the correct status of open or closed.

 

Noticed when remote start does not work and I put the code reader on it and it showed the battery at 40%.    Put optima 400 digital charger on the battery and after the charge and conditioning cycle, the remote start may work twice.     Alternator is charging fine.   
 

plan to replace the oem agm battery on Monday

 

Update 12-13-2022

 

The battery was just load tested by an large independent battery manufacturer on 12/13/22 while i watched and they said the battery tested like a new battery.   My concern was the battery may not have been holding a charge even though you could manually start  the vehicle just fine.    The reason I did this was something I found in researching the remote start failure which indicated if the vehicle battery was below a certain charge %, remote start would be disabled.

 

Update 12-15-2022

 

Took vehicle in for 3rd visit.    On the 2nd (previous) visit I mentioned to the service tech on 1 occasion I had encountered a brief "hood open" message when manually starting the vehicle but it quickly disappeared.   He was able to recreate the quick false hood open message and even though no codes were generated or stored, determined the hood latch was flakey and needed to be replaced so they ordered one and I went back for a 3rd visit a week later to get the hood latch replaced.   I also had them do an oil and filter change since the weather here is too brutal to do it outside.

 

It appears the new hood latch has resolved the problem so far and was the old latch was the electronic gremlin cause to all of the other false messages I have encountered.

 

The dealership said they have encountered a handful of faulty hood latches.

 

GM/Chevrolet need to examine and redesign the hood latch or switch to a better manufacturer of the part.

 

 It is bad when the original hood latch which just turned 3 years old on December 6, 2022 failed.

 

I doubt the hood has been opened and closed more than 36 times in the 3 years (to change oil or to /check oil and other fluid levels at approximately once a month.    

 

The truck just turned 50k and still has the original oem agm battery and the original oem Goodyear Wrangler tires.

 

I intend to get new tires within the next month.  

  

In any event, will give an update in a few weeks.

 

P.S.  Posters on this forum tend to run down "dealerships" and their service and prices,   Go find another dealer then.   

 

There is a Chevrolet dealer much closer too me, which I absolutely refuse to deal with or even visit. 

So I purchased this vehicle new  in another town and county which is a 35 minute drive for me each way.

 

The dealer I originally purchased this vehicle from has been fantastic.  They never charged me a dime for the previous two diagnostic visits because they could not fix the problem.

 

Their tire rotation fee (if you do not have a coupon for a free one) is lower than most other places.   It is why my tires are in good shape at 50K.  They are focused on customer satisfaction.    They do not want you to leave from your service visit unless you can rate them essentially 10 out of 10 (i.e. extremely satisfied).    They did not have a problem or objection  when I asked if I could walk back and discuss the problem with the service technician.   In fact it was one of these discussions which led the technician to suspect the hood latch as the gremlin/culprit.  Due to lack of generated or stored codes, it was the only real source of information for him.

 

They also gave me the old defective hood latch as I requested.  I will do some testing on it this winter when I get time.

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.
