well, get it in so they can fix it so you can be happy again.

 

That's the problem they don't know how to fix it. I started this thread last August and have a new truck that will be a year old in June and continues not to start..no engine light , no codes.just a little frustrated.

I have the same issue, started yesterday on my 2020 Denali 1500 with the 6.2. I purchased the truck new the end of April and it currently has 4900 miles on it. Crank and crank with no start. I did eve

A video of it not starting is of no use to the dealer or GM. It's not that they don't believe you but they cannot duplicate the concern. Watching it not start isn't any help diagnosing the issue.

True, but if you have a video with indisputable proof that the error is occurring, it will at least leverage them to take you more seriously and give more time to do tests needed to try and replicate

Yep. I've had the dealer tell me the GM HQ tech people don't even know whats causing this issue.  They're chasing the problem on mine now testing everything and relaying it to the techs and then trying other fixes...

I would check your states lemon laws, good chance you qualify at this point.

Yeah.  I already do qualify on the 30 days and attempts to fix.  Just spoke with the dealer and the Fuel Control Module code and Steering column sensor are on the same circuit per the field tech.  It can be anything from an improper crimp to the wire being knocked around in vibration and breaking to anything else.  Won't have my truck for another week at least.  GMC won't even cover the payment right now even though i dont have it because the situation isn't resolved.  I can't wait to see what remedy they offer.

any update on a fix?

No.  My vehicle is still at the dealer while it gets torn apart and they test modules and pins attempting to figure out wtf is going on.  40+ days at dealer and purchased on January 20th.  They have almost had the vehicle more than I have.  GMC's service advisor's cannot tell me crap regarding how they are going to make this right and I am making payments on a vehicle I don't own.  I am SO HAPPY this happened right in front of the dealer immediately after they "fixed it" last time as I tried to pull it off the lot because I had five witnesses go..."well ******, gimme the keys please".

dang...sorry to hear it....my 2020 is doing the same thing....started the first day i brought it home from the dealership.  i am taking it in this week to get it looked at but am bracing for the "problem not found" diagnosis and a long fight to get the issue resolved.  I sent GM corporate a formal complaint letter via certified mail.  I wanted to ensure i did everything to cover myself under the lemon law act for my state.  GM corporate already called me back and have started a case file for me.

This sounds annoying but take a video each time you fire up your vehicle.  Each time it happened I had the video time stamped and engine code was stored to show that this occurred and this is the code that was thrown because of this occurring.  They'll try to replace your fuel control module and steering column sensor which was done four times total with mine and did nothing.  They stopped replacing them and now think it is something occurring on that circuit because both those sensors run off that circuit.

great advice...ill do that...thanks.  ill also mention what has been happening to yours when i take mine into the shop to get looked at.  i am hoping the shop will contact GM and start comparing notes with them and other shops that are working on trucks having the same issue (like your shop)...i doubt it but wishful thinking.

I had this same issue. Dealer in west side Chevy in Katy took it and looked. They said its a Fuel control Module issue and ordered and replaced the part. Then they called to report it was good to go, only to call me back 10min later saying they went to start it and it would not start again. They had it for a few more days, say they re-tuned the module drove it around and started and stopped it a few 10-20 times with no more issues. I will report back after i pickup to let y'all know.

appreciate the post.  I ended up sending a letter to GM corporate about the issue.  Believe it or not, GM customer service contacted me and worked with my service department on the issue.  Although the service department couldn't replicate the issue when they had it, they, along with GM Corporate, are aware and if it comes up again, agreed to work together to try and fix it.  Pleasantly surprised that GM corporate agreed to intervene on my behalf.  My issue has not come back up so i have my fingers crossed.  Something to note, the starting issue happened during my first week of ownership after taking receipt of the truck from the dealership.  The dealership filled it with gas prior to me driving it home.  I am guessing they filled it with the cheap 87 octane.  However, once i filled the truck back up with 93 octane, the starting issue went away.  Coincidence?  I don't know but since that first week of problems (late April), i haven't had the starting issue resurface while running with 93 octane.

I had the same issue on 2020 LT trail boss 6.2 less than 200 miles on it.  I drove it home from the dealership and the next morning it wouldn't start.  They hauled it back and replaced the fuel control module.  I just got it back so we will see how it holds up.

      A/C failure cause???

      By Somethingclever_2014GM · Posted

      Glad it worked for you. I tried that 1st, about 2 years ago. Didn't help. I also tried doing a hard reset (disconnecting battery for minimum of 30 minutes). Worked a couple times, but after one summer of doing it over and over, that no longer worked.  I was fairly confident it was either the compressor or a failed actuator, but I just couldn't identify which one. Had to research which actuators do what and which last numbers are associated with each.

      Gas Prices

      Took me FIFTEEN MINUTES to find this. Isn't that a problem? On the mainstream media I can INSTANTLY find 100 articles bashing President Trump ... but when it comes to TRUTH in American corporate news & search engines, it's carefully filtered to support ONE SIDE. A Republic cannot survive like this! Incredible! Even all the AI searchers out there failed as well! ChatGPT said it needed more details on the video that I provided a DIRECT LINK to! I thought AI was the be-all, end-all?? I had to dig it up myself. This should be FRONT PAGE NEWS!!! 🤬   Here's the statement directly from our President:     Glenn Beck's reporting on the operation:   https://glennbeck.com/watch/videos/trump-just-revealed-a-massive-military-secret-that-lowered-gas-prices   In case that link doesn't work, here's the YouTube link:

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.
