The fuel pump power control module failed. The service center tested the vehicle and the error code was for this component. I do not believe the service center kept the part. The part failed while driving, the engine stopped running and the vehicle lost all power with no warning. I had the vehicle towed to an independent service center where it was confirmed through diagnostics that the component had malfunctioned. Prior to and during the failure there were No warning lights or signals to indicate there was a problem prior to the vehicle shutting down.

2021 Chevrolet Tahoe original owner. Fuel control module failures. 1. Failed on 6/29/21 at 5,068 miles. Dealer replaced with GM Part #13537053. 2. Failed on 8/15/22 at 12,130 miles. Dealer replaced with GM Part #13544060 3. Failed on 8/1/25 at 41,247 miles. Dealer replaced with GM Part #13554821 On each failure, vehicle was unable to shift to neutral, power remained on, electrical component began shutting down to conserve power, left stranded and required towing with rear wheels being dragged locked up onto tow truck. Once power was shut down, could not operate windows or lock doors other than keyed driver's door. Th entire failure mechanism puts the driver in an extremely unsafe situation. Recall notice #21V739000 was issued on 9/23/21 with to impacted notified owners on 10/14/21. Did not receive this notification since first failure was prior to recall and assume GM considered vehicle repair completed. Note that the fuel module part number has changed 3 times in my case, but Part # 3554821 replaces 5 other listed part numbers. Is this the 6th iteration or of this part? What is the root cause of the fuel module failure? Is it the module itself failing or an electrical issue that causes the fuel module to short out and fail. GM/Chevrolet is not solving this issue. With 3 failures of the same component, this is a lemon and I have no comfort or confidence using this vehicle. When will the next failure occur and what unsafe situation will this leave me stranded in? Read this issue applied to 2021 and 2022 GM full size SUV's and now reading issues through the 2024's. Unacceptable and poor quality. GM needs to be held accountable to solve the root cause of these failures and stop putting a replacement band aid on the problem.
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving on two occasions at various speeds, the vehicle stalled. There were no warning lights illuminated. The vehicle was not able to restart. The vehicle was towed a dealer where it was diagnosed that he fuel control module needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately 10 months later. The manufacturer was not notified of the failure. The failure mileage was approximately 67,438.
my fuel pump failed while driving on the highway with my whole family. i lost all power and my gas pedal lost all compression. I was barely able to pull off the road safely. no indicators flashed on my dash, no warning just a total loss of power and control. after pulling over, i let the truck sit for a second then tried to restart. it wouldn't. at that point, the yellow check engine indicator turned on. I logged into MyChevrolet and Onstar to see if any notifications were available to help diagnose, but nothing stood out. all systems appeared to be perfect at last check. I check temp and it was normal, oil level, normal. battery level, normal. Key battery, normal. i then started to google why my 2021 tahoe would die while driving and came across and widely known recall for 2021 GMC Full Size SUVs including Tahoes with faulty fuel pumps. my issue matched exactly to the description of what would occur. I did a quick search to see if i missed a recall notice for my truck, and didn't see anything. I was able to get my truck home and then to a dealership for a diagnostic. the only code that was discovered was for the fuel pump/fuel pump module. The dealership is now stating my vehicle doesn't qualify for a recall repair because my VIN doesn't appear on the affected vehicles list and that repairs will total $859.68 out of pocket. however, they also stated that early builds for this year may not have enough evidence. i ordered my truck, built to spec 6 months prior to receiving it. i would like my VIN added to the recall list. I have kept immaculate care of this truck and this is a known safety issue. this is my family moving rig. I don't want it to be unsafe.
Fuel Mod failed. Exactly like recall order. My unit not on recall list.
The contact owns a 2021 Chevrolet Tahoe. The contact stated that the vehicle displayed "Reduced Power," and the rear wheels started to lock-up. The contact was able to keep control of the vehicle and continued driving. The vehicle was taken to the dealer, who completed the repair under the federal safety agency Campaign Number: 24V797000 (Power Train). The contact stated that after the recall repair, while leaving the dealer and driving approximately 10 MPH, the vehicle veered off to the right and ended up partially in the next lane. The contact stated that the vehicle unintendedly shifted into neutral, and the message to "Press Start Again" was displayed. The contact was able to restart the vehicle and parked the vehicle in a nearby parking lot. The contact restarted the vehicle and drove back to the dealer. The failure recurred twice while returning to the dealer. The dealer diagnosed that there was a fuel pump drive failure. The vehicle was not repaired. The manufacturer was informed of the failure and confirmed the VIN was no longer under the federal safety agency Campaign Number: 24V797000 (Power Train). The manufacturer opened a case. The failure mileage was approximately 69,000.
Automatic fuel management/ Displacement on demand caused lifter failure which caused cylinder failures.
My [XXX] and myself were going down the interstate and my Tahoe started to sputter and the gas pedal no longer worked. I had to get over to the shoulder of the interstate because my vehicle would not accelerate. It turned off as I was navigating to the shoulder. Thankfully I was able to get there safely without causing an accident. The vehicle completely turned off and would not crank leaving us stranded on the side of the road. I called my husband because I did not know what to do. I kept trying to start the vehicle and it would sputter, but not start. Finally after multiple attempts it cranked up and I was able to get home. The vehicle has not been inspected yet by a dealership; it will be taken first thing in the morning.

I was driving home from a long trip and heard a large pop. Several warning signs and messages began popping up and the vehicle was shaking and struggling to maintain speed. I was able to get home and get my family out of the vehicle and get it to a dealer down the road. They stated the Fuel injector and harness had failed.
several issues with certain popups regarding various indicators on dash and engine not getting enough psi
Unknown - engine is driving hard and somethings wrong. No one will service my car because they say it’s on a recall, but then when they look up the VIN number it’s not on a recall however there are major issues going on.
Vehicle shut off while being driven in traffic, almost causing an accident at intersection due to a failed fuel pump control module. Engine code given was a P102a. Vehicle was unable to be restarted and had to be towed to repair shop.
Instrument panel has failed twice and is unresponsive. The gauges move and stay to the left after moving left to right. All lights begin to cycle through error messages. I have video of the issue both times it happened. When it occurs, you don't know your speed you have to guess, the full tank reads empty etc., and it is dangerous to back up. The vehicle has been diagnosed by one independent mechanic and is currently at the dealership. There was no warning before the instrument cluster failed other than a cycling through of warning messages service transmission check 4X4, service suspension system, service Power Steering Drive with care. -The center screen goes in and out. -When in reverse, the rear camera is black, the screen blinks intermittently. - Dealer has stated that the wires are put on incorrectly- if that is the case, I am not sure who would have done that other than the manufacturer. -previously reported there was a strong gasoline smell in the cabin that made it really hard to breathe. Dealer corrected. Right passenger side is intermittently wet with no cause from the interior creating stale smells, making it hard to breathe. It is important to note this is the side where the electrical wires are "put in incorrectly" according to the dealer. I also have a video of what occurs
Check Engine Light Came On. Upon Diagnosis', the engine is misfiring, lifters are not performing correctly and there are critical engine alerts and an estimate of 11,000 to fix. 2021 - 83,000 miles v8 - 5.3 NOT the 6.2 and no one will help me bc my power train expires. I am the only owner. Second brand new Tahoe ai bought from this dealership and they are doing nothing to help.
Check engine light comes on. Car suddenly stalls and engine shutters, shuts off and on. Goes into limp mode as engine shutters at about 15 miles per hour. GM has not included this 2021 Tahoe which is the same exact condition under Product Safety Recall N212332040 "Stall While Driving". That recall was issued at the same time or month as this Tahoe was built and sold and should have been included. This Tahoe was towed to the dealer and GM has not been able to supply parts. The Tahoe will soon have been at the dealer for 60 days with no solution. The recall build dates should be expanded to include all GM vehicles with this defect. It is explained as: "The fuel pump power control modules in these vehicles may contain a supplier manufacturing defect that can cause the fuel pump to fail or operate intermittently, interrupting the flow of fuel to the engine. If the engine does not receive adequate fuel, the vehicle may unexpectedly stall. The driver may see a check engine light, receive an OnStar notification that a Diagnostic Trouble Code has been set, or experience a rough running engine. The vehicle may also be placed into a reduced power mode. A vehicle stall without warning could increase the risk of a crash, especially at high speeds"
On May 14, 2023 I was on a trip driving the Tahoe (midnight blue Tahoe in the pictures) about 60 mph, on highway 41 (middle of nowhere, no cell reception) south of kettleman city, CA when, without any warning or symptoms of any problem whatsoever, the engine lost propulsion and died. I was able to coast onto the shoulder and tried starting it. It started again and I continued driving and about 35 minutes later I stopped at a red light on Highway 41 in Lemoore, CA. Again the Tahoe engine died without warning and would not restart. When I tried starting it I could smell a burning smell. The engine cranked but wouldn’t start, and then the check engine light came on. I was at a stoplight on a major highway and was unable to move the vehicle, and was scared to sit in it, so I put on the vehicle hazard lights, got out of the car and ran to the side of the road for safety. Luckily I did not have my children with me. I called 911 and a police officer came and parked behind my vehicle with his lights on so hopefully no other vehicles would hit it. A tow truck was immediately dispatched as high priority by the police. I had it towed to Hedricks Chevrolet dealership in Clovis, California, who informed me there was metal parts in the oil and that the engine was destroyed and had to be replaced. It took several months to get the engine replaced and in the meantime, I bought a new 2023 Cadillac Escalade so I would have a vehicle to drive. The Cadillac Escalade ended up having an extremely similar problem (and I will file a separate report for that vehicle). A few months later when the Tahoe replacement engine was installed I picked up the Tahoe from the dealership and sold it to Carmax.
Vehicle smells heavily of gasoline/fuel exhausts to the point of headaches. Vehicle obtained just over one year ago currently with dealer.
I was driving the vehicle, exiting the parking lot when the engine and all electrical components turned off. This could have easily caused and accident as there were multiple vehicles that had to go around me while I tried to restart the vehicle. The engine would crank but not start up and left me stranded in the middle of the road AND in the middle of two lanes. When I finally got the vehicle towed several days later (which was not easy because in order to put the transmission in neutral without the engine being on, a special tool is needed) I took it to the dealership. They confirmed it was the fuel controller that went bad for the second time. The first time the vehicle was stuck in my garage at home with the same symptoms. They apparently replaced it with another faulty part that is a ticking time bomb. I have no faith that this won't happen again.
Fuel Pump Module Failure at 27k miles, experienced total loss of power while driving. GM issued a recall for this part in other 2021 Tahoes, but said my vehicle is not included in the recall. Researching online this seems to be a large problem with this model year, yet they did not recall all vehicles. Clearly mine was effected.

Driving at 35 MPH and the engine cutout and stopped on 8 November 2024. I was able to pull over safely as I was on Vandenberg Space Force Base, but at highway speeds in traffic this would have been very dangerous without power. The local GM dealership at Lompoc, CA confirmed the fuel pump control module failed, which caused the loss of engine power. There was a recall for the 2021 Tahoe fuel pump control module, but my VIN was not included in this recall. Currently the fuel pump module is not in stock and GM has no estimation for when the part would be recieved

This is in addition to complaint # 11621324 The dealer now says it is the FUEL PUMP MODULE that is bad. Same item as on previous recall. They say it will be covered under emission warranty but not the fuel pump. At $1500 for fuel pump. However - they replaced fuel pump before discovering the module issue. They either did not test fuel pump properly, or, fuel pump was not bad, only the module. Or, if bad, the module caused the fuel pump to fail. Either way the fuel pump should be covered under this module recall too as a related cause from the faulty module(s) that were recalled.
I was stranded and had to have my vehicle towed after the fuel pump control module failed.
Vehicle has 10,800 miles. The vehicle repeatedly failed to start. Towed to GM dealership. They say the fuel pump has failed. They say it is not covered (beccause my VIN isn't within the recalls that already exist for this exact same problem). The cost is over $1,200. I contacted Chevy corporate and they offered to cover 30%. The dealership is still awaiting the part(s) with no provided delivery date. This could have caused a serious MV accident if it had failed while driving. The vehicle gave no warning of this failure.
