GM 13540028 Fuel Pump Driver Control Module

gypsy1962 · March 10

I own a 2019 Silverado High Country. Truck has just under 30k miles at this time and is in pristine codition. Has run like new since the day I bought it. I love the truck, best I've ever owned. Just after new years on 2 Jan, went to head out to grab some things. Crank, No Start. Put a scan tool on and found DTC P129F. Had it towed to dealer and they confirmed. Was also informed part was on national back order. Still at dealer today. I was contacted by GM Customer Assistance 2 weeks later and was assigned a case number. I get weekly calls where they continue to convey NO ETA, and of course continue to coddle me with sorry, sorry, sorry and stories about the supply chain, etc, etc, etc. I've called well over 100 dealers accross America - back ordered. Those that had it, refused to sell to me since I didn't buy vehicle from them. A few busted their tails trying to help, but no joy. I've bought two (non-OEM), from ebay, neither worked. I understand that many customers are in the same sad position. I'm at my wits end. A couple of days ago, I sent a pretty nasty letter to GM - Mary's office. Got a direct call 2 days later - Friday. They took ownship of the issue and gave me new case number and said I'd hear back from them NLT Tuesday. We'll see. I'm a retired electronics engineer so everyday is pretty much a saturday these days. Decided to dig into to this part thoroughly. Service diagrams, TSBs, and more. Pretty much just a module that drives the 3 phase brushless fuel pump lift motor in the fuel tank via canbus (GMLAN) and it receives signals from the ECM over the bus when fuel is demanded from the tank. It talks to a few other modules as well using dc signals. As far as I can tell from reading whatever I can get my hands on, this module has been revised at least 3 or 4 times since 2019. Additionally, this very same part is used in numerous vehicles to include the silverados that continue to roll off the production line today. GM's priorities are obvious, new sales over support for prior customers. What frustrates me the most is why Chevrolet engineering has not designed an alternate part. This part is not that complex. I am just not buying the supply chain story. It seems pretty clear from this, and other like stories that GM has lost it's focus on Product and Service excellence it had in days gone by. To highlight this point, my wife bought a new Blazer Premier the same day I bought this truck in 2019. It has 3 times the mileage compared to my truck and she loves it. So much so, she was temped to buy a 2024 Blazer EV - not that we're big EV fans. This one got rave reviews right up until the point where GM put a stop sale on them as soon as they started arriving at dealers due to a complex set of software issues. The stop has yet to be lifted. What the f^&k GM? It seems that GM is heading in the same direction as much of the country - no leadership and increasing incompetance.

I think we may be talking about the same thing... I pulled up to a stop sign last Saturday and my 2019 Silverado Crew Cab stalled as I went to turn. Everything was perfect up until that point. I turned the ignition Off and then Back On and the Check Engine Light came on as well as the Low Fuel warning. I knew something was wrong because I had 3/4 of a tank of fuel and my Fuel Guage showed I was empty.

I had my Silverado towed to my local Chevrolet dealership and waited until Monday. According to my dealer service department, the problem is the Fuel Pump Control Module P/N GM 13540028. Unfortunately, there are 8 more trucks ahead of me needing the same part... And one truck has been waiting since November 2023 for the part to arrive. To make matters even worse, I was told that some of the trucks had the part fail at 5k miles and several others fail at 10k and 20k miles. Evidently, my truck with 49k miles was one of the highest mileage.

After thinking about 9 trucks at one dealership experiencing the same problem makes me wonder why there was no recall on the part. Better yet, there's no telling how long it will be before the part comes available and when it does, how long will the replacement part last before it fails. I agree with the OP in that the whole supply chain excuse should not be an excuse if Chevrolet Management were doing their jobs.

I too am in central Florida. Mine has 27,500 miles. It's completely unsatisfactory behavior by GM. I've heard the same story from every dealer I talked to. Some even willing to agree and say as much (but quietly). Many trucks offline is the story I get. Mine is still inoperable waiting for the part. After my letter direct to GM, I got the call I mentioned 2 days later, then a follow-up call Tuesday last week. I was given a maybe-ish date 30 April and no guarantee that date was any good. They did state that it's definitely made off-shore (can't imagine where). Regarding my request to diverting some parts from the current production line, I was told that each module has vehicle unique calibrations loaded therefore diversion from the production line was not possible. If that is true, I thought, then divert the part and load the Calibrations unique for mine upon receipt. Pretty sure that was complete bullsh%$# because every GM tech manual I've read, and every tech I've talked say that no SW or Calibrations are required for this module. My research indicates the part has evolved through these part numbers: 13531875, 13558812, then 13540028. I've heard/read there was a fourth, but I can't confirm its number. I'm not sure how, but I think this issue needs the widest possible dissemination to be able to have some negative impact on GM, but I'm not sure how best to do this. Here's the diagram if you're interested.

You have been without your truck since Jan. 2nd? How are you getting around? Has your dealer given you a loaner?

gypsy1962 · March 18

Wife has a car she bought the same day as I bought the truck, I've been using hers for the time being. Closest dealer (Carl Black Orlando) I took the truck to does not offer loaners only sympathy. Original dealer neither. GM offered to cover payments throughout the ordeal. They have covered January, and promised February 3 weeks ago. Nothing received as of this date. What a country...

I went on GM Parts to try to search for a part anywhere in the US and evidently it doesn't work like that. You have to put in a Zip Code and you are referred to a GM dealership in that area... Which you find out does not carry the part. I called numerous dealers and was told they have "X" number of vehicles waiting for the part. I then called GM Parts and the Customer Service Representative told me me they cannot do a global search accross the US.

I was then transferred to a Case Manager that is trying to help me with my situation. I explained to the CM that I have two major concerns... First, based upon the number of vehicles affected by faulty Fuel Pump Control Modules, many of which have very few miles on them, what assurance do I have that if/when I do get the part it won't fail in 5k, 10k or 20k miles and I'm in the same situation again. Second, from my research this part is still being used in various GM models. How is it they have the parts for production vehicles but not their Loyal Customers who now have a $45k and up Paperweight.

I Googled GM Part Number GM 13540028, checked on Rock Auto, etc and from what I can tell it's a GM exclusive part with no aftermarket support. That said, I found 74 GM 13540028 for sale on ebay. Some showed shipping from the US while the majority shipped from China. The prices ranged from $70 to $370 with most being around $100. I messaged about a dozen vendors asking if the part they are selling is a GM OEM Part and every single one replied that it is an aftermarket equivalent part. I watched a couple videos and from what I saw a Fuel Pump Control Module has to be programmed and who knows if the ebay part would even work. Then again, I wouldn't be surprised if the GM OEM Part was made in China by the same company making the ebay part.

I'm half tempted to order the ebay part and ask my dealer install it. My guess is they would refuse and even if they would, would it program correctly. Then again, could it be any worse than the GM OEM Part. It's very frustrating when you pay for a vehicle and it doesn't work... Not to mention your told there is no ETA for the repair part. This is my 4th GM truck, the other three had 250k miles or more when I traded them without any major repairs. This one may be my last.

I provided 3 from ebay to the dealer thas has my truck, none worked. They made me sign a disclaimer that said using a non-OEM part may jeapordize any remaining warranty. I added the sentence: "I take this action as a result of GM not being able to supply an OEM part", and signed it. Sounds like you've covered all the same bases that I did with no joy. I've spent 2 months seaching, calling, getting nowhere. I've had friends in other states search locally where they live - nothing. I was given a tentative date of 30 April and they have not called (as they said they would do weekly) or sent any further payments since the 1st. This speaks volumes about the lack of honor and integrity in today's GM leadership. The employees I've spoken to that have tried to help, quietly agree, but have no authority or options to do anything about it without risking employment. In the letter I sent to GM, I listed out over 1 dozen Chevrolets I've bought since my teens, many brand new. Does it matter to them? The evidence says it does not.

This may sound stupid or obvious but what about a junkyard or "auto recycler" like they like to call themselves? If GM cant/wont help you you will have to try something else.

Just an idea.

I found a few trucks in salvage yards, but the module had already been stripped out.

I’ll check on the junk yard version. The amazon version is chinese and is the wrong part number. see top row as you read right to left. thanks for trying to help!

Same boat and no luck finding a part either at the dealerships or from a salvage yard carrying any of the vehicles that use the same part. I have a part on order but from looking at others results with trying to find an interchangeable part, I don't have high expectations. There were 4 on backorder at one dealership I called and 2 are backorder where my vehicle is being serviced at. My truck is just out of warranty and after not having my 3-4 months last year due to 2 different transmission issues, this is really tarnishing my thoughts on the GMC brand. Even if the part does come in, there is such a backorder I don't see my vehicle being fixed when the initial delivery of parts are received. From research it looks like this occurs due to poor sealing and water getting in the units. If I do get a part that works, I'll probably try to seal it better. Seems like if there is this much of a backorder, they would be taking the bad 13450028's and trying to fix them and then replace them with new once their stock is replenished. The fact that they would be producing new vehicles with the same or similar part, while not taking care of those that already own like new vehicles is even more frustrating. So, they are just going to keep putting more vehicles out that will have the same part fail causing more issues and more backorders.

Also filed complaint with NHTSA.
