I have a 2022 Silverado RST bad module and only 8k miles. Part is on back order nation wide! Dealer saying 2/3 weeks. I need to get compensated for this bullshit. 60k piece of ******. I should have kept my 2013 GMC Yukon with 140k miles and never been in the shop. 😡

I have a 2023 AT4X 6.2L.  At 2750 miles the fuel pump went bad. Motor went into limp mode with reduced acceleration. Took my dealer a week to even get to it. Found out the fuel pump was shot, trailer break controller was bad along with 13 codes thrown. Truck has now been at the shop for 4 weeks (both parts were backordered) plus the week it took to get it on the schedule, so 5 weeks total to date. Had to insist they rent me a truck. Hopefully this is the last time its in the shop for anything major. Pretty ridiculous to see that similar issues have been going on for years over multiple model changes. Get you ****** together GMC! You're certainly charging premium dollar to us, the product should reflect your sticker.

I have a 2022 Silverado and got stuck in remote area. Starter works no turn over threw a code p129f fuel module. So now 3 days later truck still broke down in remote area. Trying to get a wrecker to it.  This is unsatisfactory and Chevy should have replaced them before it went bad. Vehicle still under full warranty. The cost is the towing at this point. Hope insurance and Chevy warranty helps out.

I have a 2020 Sierra AT4 and having codes p0499 & PO488.  Does anyone know where the location of the fuel pump control module is.   There is not a lot of good information that I have found so far as to location and replacing.  Frustrating is an understatement.  Thank you for any help!

I'm not a member here but I do  have a 2020 sierra with 75,000 miles on it and my fuel pump control module is going out. There is a federally mandated emissions warranty on them for 8 years or 80,000 miles. I am having mine replace at the dealership under warranty. The dealer should inform you of this. If you have had it done you should be eligible for reimbursement. I just learned this with mine. Check into it.

2019 LT w/only 31K.  Would hesitate sporadically and a couple of hard jerks but didn't think too much of it.  Was going down the road doing 55-60 and suddenly hard jerked and check engine light showing "no fuel".  I barely made it into a park.  Had it towed and sure enough the mechanic had to replace the fuel gas module.  I am at a loss that this issue is widely known and yet we pay good money on a truck that GM knows there is an issue.  Of course my 3 years is up but my mileage would have been under warranty.  May look into an F150 next time.

Is there something I can do to avoid this failure?  Is it the luck of the draw manufacturing defect?

No nothing you can do to avoid this failure. Fuel pumps and modules have been going out since cars were first invented.

I had a P0499/498 and took it to the dealer. I ask about the Emission warranty until 83k as shown on my owners portal and the dealer advisor told me it only covered the catalytic converter and PCM in Georgia.. cost me 665.00 to get it replaced for the fuel pump control module.. so how did the gentlemen in the earlier comment have his covered? Gongrats to you mate. My truck is a 2019 LT trailboss with 55,700 miles on it. Really like this truck but its about one more check engine light from getting traded for a Ram Rebel... 7 times to the shop in 55K about had it.

23 5.3 1500 LTZ with 16k miles.

I’m fairly certain the same problem.

We were on the way to lunch and going through an intersection when the engine cut. It wouldn’t fire up; just turned over and over.

 

Called a tow truck and had it dropped at Chevy.

2023 Sierra SLT 5.3 with 11k miles (at the time).

 

About 2 months ago, my truck suddenly would not start one morning, and I'm still under factory warranty. OnStar authorized tow delivered it to the dealer. Cause was a failed fuel pump power control module. This may, or may not, be the same as the fuel pump issue the original poster mentioned.

 

Here is the info from my service record if it helps.

Campaign: 24-NA-139

Service finding: code U18A2, loss of communication with fuel pump driver control module

Part replaced: 13554821

Just got my truck back; was same thing. Fuel pump control module was shot. They had them in stock; took a day to fix.

    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

    • I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip. 
    • Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
