So, my truck will be going back to dealer for the third week in a row. First we had four instances of intermittent flashing CEL which after three visits, they found some loose intake manifold bolts. 
 

Today we took a drive to the Gulf. Parked truck and got a text saying that it had an emissions problem. Shortly followed by email. So, had to drive all the way home with a solid CEL. New truck with less than 1000 miles. 
 

I have always been a staunch Chevy guy but this truck has made me seriously think about cutting my losses and going Ram.

Well, just started the truck, both normal and remote, and the CEL is no longer on. Still have the issue per myChevy app though.

Update. At dealer. 
 

- Generic P0300 code stored. 
- As of this morning, the myChevrolet app says there are no issues with the truck. 
- Tech cannot duplicate issue. 
- Computer files going to GM engineers. 
-Dealership now waiting call from engineers. 
 

I have two choices. Drive vehicle that may have issues or leave it at dealer which does not have any loaners available. Very frustrated right now.

I'd leave it with the dealership and have them get you into a rental until they fix it.

Could not do today. If it goes back, I will be demanding a rental.

So, dealership called today. The engineers want to do a "porcelain tap test". Truck needs to be completely cold. So, dropping it off Sunday so they can work on it Monday. Stand by for the update.

Did they get you a loaner?

So, it is back in the shop.

Dropped it off Thursday night so they could do a "tap" test on Friday. Guess that is the spark plugs. No issues reported on Friday. So, now they are keeping it into next week. Looking at dropping gas tank to check for contamination!

So, $60k truck. Owned just about six weeks with right around 1200 miles (we were out of town for a bit).

 

- First two days (March 15/16), two instances of flashing CEL lasting ~15 sec. Visit #1 (16 or 17 March) no codes.

- Third flashing CEL event (10 or 11 April). ~ 30 sec. April 12, visit #2 P0300 code. Could not duplicate. Reset codes.

- Fourth flashing CEL event. April 18. Flashing CEL ~ 1 min. 666 miles. Have video. Only shut off when Auto-Stop happened. Visit #3 on 19 April. P0300 codes. Found 3 loose intake bolts. Reset codes.

- April 24. Drove to Clearwater FL, ~2.5 hours, 150 miles. Parked truck. Got text/email alert that there was emissions problem. Started truck. Solid CEL. Called dealer, made appointment for Monday 4/26. Told was OK to drive home. myChevrolet app showed emissions issue. Started truck that night at home, CEL was out. By Sunday, app showed no issues.

- Visit #4 on Monday 4/26. Stored P0300 codes. Could not duplicate. Problem elevated to GM engineering.

- Visit #5. Thursday 4/49. Dropped truck off for extended testing.

 

Oh, and I did get a loaner. Base model Trax. 🤬

Final update. Dealer had the truck for a week. Drove it 200 miles. Did multiple tests and could not duplicate. They did see misfires on #1 and #6 in the data. Swapped plugs around. I can only surmise that something was loose and they corrected it.

 

Truck is back with me. Did 150 miles so far this weekend with no issues. Fingers crossed.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
