PO50D

Bigmike46 · May 8, 2018

My 2014 Silverado had the same code P050D and I took it to the dealership and they replaced 2 defective fuel injectors. That was on 24 April 2018 and yesterday (7 May 2018) the code comes back????? I am taking the truck back to the dealership this afternoon for another diagnostic. I am sure it is fuel injectors. The technician suggested that I replace them all but my extended warranty wouldn't do it and I can understand that. If this is going to be happening every couple of weeks we have a serious problem! I purchased the truck new in 2015 and have 59,611 miles on it and this is the first major issue so far.

Update of code P050D. I had another defective fuel injector The extended warranty company authorized Chevy to replace the remaining 6 injectors. I was very pleased because I couldn't see myself coming in every couple of months to replace 1 or 2 injectors. Now the warranty is on GM for 12 months. Lets hope this is the last fuel injector issue I have with this truck.

Well, the fuel injector issue was just the beginning of my problems with my GMC. The horrible projector headlights was next. Followed by losing the condenser and compressor for my A/C. The driver's side seat back kept falling off, even within minutes of a new replacement! Then, to boot, my mileage dropped 6 mpg between city and highway with no reason (or at least the dealer couldn't find a reason). All this with only 37k miles! I had had enough of this truck and went back to a Ram five months ago and have been much happier. GM has lost another customer.

I received a call Saturday from the service department stating that fuel injectors were back ordered and they didn't know how long before they would be available. WTF!!! Who is running the supply chain at GM!! It makes you wonder if these injectors are failing at such a rate they can't keep up. This is unsatisfactory!! I am paying for a truck I can't use and to make matters worse I need my truck for my upcoming vacation and the dealership doesn't know if they can provide me with a truck.

After almost 4 years of ownership and almost 60K miles I was happy with my Chevy. I am fortunate I have the extended warranty, it has paid for itself after only two service visits. I will be researching other truck options once I get the truck back. I am concerned that the fuel injector failures will come back later down the road if GM doesn't change the design. I could be doing this again at 80K. The Dodge Ram is looking better every day:-(

I had this issue on my 15 6.2 at 24k miles. It was at the dealer for 2 weeks due to backorder of injectors. They replaced 3 under warranty, so far so good.

Bigmike46 · May 29, 2018

I got my truck back this morning after they replaced 6 more fuel injectors. I took them 2 weeks to get my truck fixed. So far all injectors have been replaced by the dealership. I am really considering getting another truck due to the reliability of these injectors. What will happen a year or two down the road?? I like the truck but don't want this headache later.

I purchased fuel this morning at a Chevron station in Houston, TX. Immediately upon restart after fueling I had an engine light on the dash. Before driving home tomorrow (700+ miles), I had Autozone run the code. It is P050D. 29,546 miles on a 2017

TJay74 · August 10, 2018

i would have them reset the code and see what happens, if it comes back it is more than likely a bad injector. I just got my 16 back with the 6.2l last month for the same code. 1 week later and 1 new injector and I was all good to go. Truck only had 22k miles on it at the time.

Im guessing mine is having the same problem.. P050D is popping up 87K miles old. this is frustrating because it was just misfiring on cylinder 4 a month ago with code P0300 (Random/Multiple cylinder misfire) of course took it in to the dealer i bought the truck from had it serviced and now this.. 2 codes P219 and P050D.. all in the same week that it was just serviced for P050D.. took it back to the dealer only for them to of course deny everything as the all do i imagine.. but then said they will look at it for me but it will cost me the diagnostic fee.. why would i pay that again if i already paid for the misfire issue... im loosing fait in GM to be honest. My Dad's old Tundra at 120K miles is still runing properly with all original parts yet mine is becoming a money hole... please let me know if there is any way to fix this myself.

I know this is an old post, but I'm getting exact same errors. What was the solution to this? Injectors?

Your dad should consider himself lucky because the Tundra has several very common issues that costs far more than replacing a couple injectors. Just a basic "Air Injection Pump" for a Tundra typically costs $750-1000. The pump itself at one time was costing around $400, wasnt covered outside of the bumper to bumper warranty, and they failed often some guys have had to replace them 2 or 3 times (cold weather regions). Starters on 2nd gens are extremely common problems, usually fail at 60-80k miles, and it's usually an 8 hour job to change it. The rear axles are a major problem on these trucks. The Hino axles they use leave a lot to be desired in terms of durability and quality control. Many earlier 2nd gen Tundras had wheel bearing failures in the first 40k miles in some model years. Even now there are a surprising number of pinion bearing failures and even problems with the carrier being made of steel that was too soft, requiring a lot of money to totally rebuild. Their 2-piece driveshaft design also sucks.

As mentioned previously, it can be as simple as a bad tank of gas. If you've run through a couple tanks using different stations then the next common solve is replacing your injectors. I'd recommend doing them all at once since, as others have said, the problem can pop back up with the injectors you didn't replace. If that doesn't do it, you can have a more serious issue where coolant is leaking into a cylinder (or multiple) and causing a hard cold start up because it has to burn the coolant off the piston. Coolant can also be leaking externally from a head bolt. If either is the case, the solve for that is replacing the driver and/or passenger side head. Apparently the original manufacturer that cast the heads for our trucks didn't always do a great job and pinhole leaks can occur allowing coolant to go where it shouldn't. PIP5498 gives more detail (https://www.corvetteactioncenter.com/tech/knowledgebase/print-1364.html). Don't let this freak you out though, MAJORITY of the fixes for P050D have been getting good gas back in the tank or replacing injectors. It's rare to have the coolant leak. If you're still under warranty I would take it in ASAP to get it on record that you're trying to fix the issue. That way if you go over a warranty, they will still cover any costs with fixing it.

I've been hearing different answers from different people. Do you know if injectors are covered under power train warranty?

I should add I'm also getting the P0300 on cylinder 8 as well...

Yup, power train covers them. One other cheap attempt you can try is throw a bottle of Chevron Techron fuel treatment in your gas tank. It usually doesn't fix the issue, but in some cases the treatment can clean your injectors enough to not throw any more codes. Worth a shot for a few bucks, but I'd take it to the dealer ASAP to start the warranty process.

I am having the same problem with my 2016 it started about 4 months ago with only 47k miles now; after replacing spark plugs, o2 sensors and going crazy... dealer told me I have a bad injector # 7 however the recommend to replace all 8 injectors and while we are at it replace the fuel lines at a "discounted" price of only $1800. ( it stinks to be asked to pay that much for truck you are still making payments on)

The service adviser pulled all the lame excuses; he even told me I have been putting some bad gas in there, I told him that it was the same gas that goes into the rest of the cars in my household and none of the other cars have any issues. (a Ford and a Honda that are running like champs with more miles)

Gordon and Partners is a law firm that has a office in the same building where I work; they have filed class action law suet in the past against car makers before for problems such as this one... as son as get around to it I will let you all know if we have a case and see if you would like to participate.

Come On Man... You are not sorry if you don't have a solution. Telling us that you will gladly hand us names of dealers that make your company more money isn't help, it's advertising. This Seems like a Huge ongoing problem. I have seen a lot of people having this same issue and it really sucks. Mine shut off on my this morning and when I started it up the engine light came on and sure enough P050D code. So now I don't know if it is going to catch fire and blow up or what. I put a can of seafoam in it, hoping that would take care of it, but nope. Not yet! So now I am guessing I will have to take it somewhere to get told they will have to do so much more than they really will and hand over my first born. Ugh... For a truck with so little miles there has been far too many problems.

I feel you pain my truck now has 47k miles it has been acting up for about 4 months... new spark plug, new O2 sensors, just about every brand of fuel injector cleaner, seafoam in every form possible. Dealer wants $1800 to fix the truck I'm still making payments on!
