Yeah, don't buy one.  Get a scan tool with bi-directional communications that was made for your truck.  GMs MDI2 with GDS software and a laptop will allow you to see all the codes and runs graphs and diagnostics and tests and resets, etc. on your truck.

 

Thanks.  I will check it out.

Update from my last post on May 14th.  Dealer originally said my 5 year power train warranty was covering the replacement of all 8 injectors.

 

Waited about 5 days and heard nothing back.  Called service writer and was told the injectors would not be covered.  I asked if they could check to see

if the injectors would be covered under my extended warranty - GMPP - GM Protection Plan - which expires in 2021 or 84,000 miles on odometer.

 

They checked and said GMPP is covering all 8 injectors and my deductible is $200.00.

 

Now the dealer did not clear the engine light the second time it came on.  It has remained on - until yesterday - light went off and has not come back on.

 

Waiting to see what happens.  Do these CELs normally go off after a certain amount of time?

 

Truck still runs good - only I notice a sight rough idle when starting truck cold.

 

Purchased truck new in August, 2014.  Now has 30,000 miles.

When the CEL turns off on it's own depends on the specific problem.  Some problems, like if the MAF sensor is left unplugged, will turn off right away when it's plugged in again, others will need a certain number of ignition cycles without the problem reoccurring before the light goes off, and others will require one or more testing cycles to complete before it goes off on it's own (where the testing cycle may not happen immediately or take some time to complete).

Update from my last post on May 25th.

 

My extended warranty - GMPP - GM Protection Plan - which expires in 2021 or 84,000 miles - is covering the cost of the 8 new fuel injectors less a $200.00 deductible.

 

I dropped my '14 GMC Sierra off at the dealer today at 4:30PM.  Service Rep said I should have it back Thurs. afternoon.  I was informed the 5 Year PowerTrain warranty

does not cover fuel injectors.  FYI only code P050D logged when CEL came on.  No other codes.  Will post again after I get the truck back.

Picked up my truck from the dealer today - Wed, June 12th.  All 8 fuel injectors were replaced.

 

Receipt lists  " INSTALLED 12684125  :SL-N-INJECTOR KIT (0300-CT)  Qty: 8 "

 

My "receipt" lists no numbers for labor, materials, etc. - just says Warranty under Amount.

 

I did get a look at the paper with the total on it - around $1,200.00.  Dealer service rep said something about

their cost billed back to GMPP and my cost without the extended warranty would have been much higher.

 

I paid $200.00 - my extended warranty deductible.  Time will tell if this fix works and keeps the CEL off.

I am having the same code and problems with my ‘17 Silverado with the 6.2 with 47,000 miles. Dealership said that the injectors aren’t covered under warranty even though they know they are a problem. How do I get GM to warranty these?

Unless you got the letter from gm stating they extended the warranty on the injectors on your specific VIN, plan on paying for them yourself. If you're mechanically inclined do it yourself and save a lot of money. All you need is 8 injectors, which might be hard to find with the strike, 2 high pressure fuel lines and 8 intake gaskets. There's videos on YouTube showing how it's done. It should only take 4 hours or so depending on skill level. Just make sure the holes in the head where the injectors go are clean and free of any burrs.

I replaced my bank 2 injectors last week then had 2 of them fail again this week. Second time took me less than 2 hours. Only thing I can guess is there was something in the hole that nicked the seals and caused them to fail prematurely. Either that of there's something wrong with my engine causing the seals to fail. Both times my injectors failed was on cylinders 4 and 6 which are AFM cylinders which has me thinking there's something deeper going on. I guess we'll see if I can make it more than a week this time.

with the P050D code...'16 silverado, ~65k miles, no extended warranty...the CEL has been coming on and off for quite some time...but since i checked it, it has always been the P050D code...first recommendations were to flush with injector cleaner...i have done that a few times...seemed to work eventually...but i am to the point it must be something more...would it be worth changing the spark plugs before i take it to the shop?  that is one of the recommended fixes (and would be MUCH cheaper than injectors) but i dont want to just through away $50-$100 on spark plugs if they arent needed...

 

if not, since i am out of warranty, i dont plan on going to a dealership...plan on going to a regular mechanic...any idea what the damage will be?  sounds like the $1200 mentioned above was internal charges...i'm nervous what the bill might be...

 

this has been the worst chevy (out of three, i have bought each brand new) i have every had...it is frustrating as hell...

I had that same code but a p0300 also and was started to blow white smoke out of the exhaust. I ended up just paying out of pocket for injectors and fuel lines. It wasn’t worth the fight with GM. My mechanics checked everything else out also. Spark plugs were fouled and the cylinders weren’t washed out with fuel. He changed the oil though and did an upper induction cleaning   I just got the call today that it’s done, a month and a half later, about to write an $1800 check for 8 new injectors, new fuel lines, oil change, and induction cleaning. If you do just the injectors and fuel lines it should be around 1,200-1,400

What part numbers are you guys getting for the injectors? The ones that came out of my truck are 12668390, dealership said new replacement part was 12684125, but then looks like 12698484 is the newest part. I ordered 12698484 from GM wholesale dealer, box says 12698484 but the injector is stamped 12681212.

 

Seems like a lot of conflicting info on this fuel injector issue..

 

12681212 (that I just got in today) is grouped with 12668390 (that came out of my truck) under the latest replacement number so I'm guessing I can use these. Everywhere is back ordered so I guess I'm lucky I even got these

      GM discontinuing interior parts on a 5YO vehicle??

      By Atlas · Posted

      If one can't be found, a good automotive upholstery shop should be able to replace/sew in a new panel where the damage is on the old cover. It might not be the cheapest option..

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Does your dealer charge you for the tire rotation on top of the oil change price ?. I haven't had any service work done at my dealer yet other than when I brought it back soon after owning it to have the front end aligned to correct the steering wheel being off center a bit. Oh they called me at least twice hounding me to bring it in for an oil change and pushing a 300.00 package of oil change and tire rotation and whatever other quick simplistic checks they would do. Only going off of what a friend gets charged for his half ton for the basic oil change and its the same amount of oil as the L8T holds, it was about 150.00. Once one buys a set of tires from most shops these days or so I believe, they will do free tire rotations and some do free tire balancing as well as free tire repairs.    Certainly doing a tire rotation is no five minute job, and definitely not at home but because I run a set of winter tires on their own wheels, I swap them at home and its a one tire at a time deal because of the tire season swap although I jack up the rear and do it and drop it back down and then raise the front and do them and coordinate the tire rotation into that process for both sets of tires. I am using a floor jack though and if I need to raise both ends at once I use a couple sets of jack stands to have all four tires off the ground. I use either an air impact or battery impact and have electric impact as well so no shortage there of easy methods to spin the lug nuts, and then retorquing the lug nuts. None of it goes quick though but my wages are cheap though ... zero. I live an hour out of town, its easier just to do things like that myself than waste a bunch of time in town and having to make an appointment and probably a special trip and sit there at the tire shop waiting for them to get my vehicle in and get it done and not screw something up in the process.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      I do have the 8 speed.  Interestingly enough, after driving my truck for the past 2 days now, I have not had the clunking issue at all!  I am beginning to think it may have been suspension/leaf spring related, and somehow when the shop put my truck on the lift to do their initial inspection, it relieved some built up tension/pressure that was causing my problem.  I swear it felt I was a bull rider on a bucking bull the way the truck would almost rock back and forth slightly before the big thud/clunk when coming to a stop.  I am hoping I got lucky here and it's gone for good.

      Bring it to discount tire. They do free rotations even if you didn’t buy your tires there. I didn’t believe it until I tried and they did. You can tip the employee if you would like

      Best part of this video is how it resets expectations. Wonderfully done piece. It also made clear a few points I've made from day one. Detergent oils DO NOT KEEP A MOTOR CLEAN at the recommended or longer change intervals. They just get dirty slower than a non-detergent oil and there isn't spits difference between them on this point if they carry the DEXOS license. Great thing about the license that gets missed is it assures CONFORMITY even it that means a low bar.    One thing he did not talk about that I paused on an magnified was the condition of the oil ring separator. Besides a stuck ring a plugged separator and land drain back is huge when it comes control. We see in short order improvement in control IF that is the problem.    Another item I took exception to and he did not make plain was the condition of the timing chest and under valve cover having something to do with indicating piston cleanliness. Schaeffer's Oil makes that same omission in their million mile Ford video. I'm guessing he has never torn down a Red Line HP, AMSOIL SS motor that has been on that diet from the get. What he showed in the video was a good deal of varnish. Something totally absent in Peppers 165K cover off look. I smiled because he did his at the same milage.    He also makes the mistake of assuming oil temperatures in the pan are the temperature all over the motor even though he makes note of the piston being the hottest part of the engine. that baffled me a bit.    I can tell you from personal experience and witnessing teardowns of family motors that even oils of the 1960's would keep them squeaky clean when OCI's were 1500 to 2000 miles without exception. At 3K and above you get what he experienced and the longer you leave it the quicker to gets to the junkyard.    I think his is missing a opportunity not tearing it down again when he's done killing it. Time would be his only cost.
