1. What component or system failed or malfunctioned, and is it available for inspection upon request" Answer: The vehicle-??s 6.2L L87 V8 engine suffered a sudden internal mechanical failure involving the connecting rod, rod bearings, and crankshaft assembly, resulting in catastrophic engine damage. The failure mode is consistent with the defect described in GM Recall N252494001. The engine and all damaged components are fully available for inspection upon request. 2. How was your safety or the safety of others put at risk? Answer: The engine failed without warning while the vehicle was in motion, causing an immediate loss of propulsion. This created a hazardous situation where the vehicle could no longer accelerate or maintain speed in traffic, increasing the risk of a rear-end collision or loss of vehicle control. GM-??s own recall documentation identifies this exact failure mode as a significant crash risk, and that same hazard occurred in my case. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Answer: Yes. A service technician confirmed catastrophic internal engine failure consistent with connecting-rod or crankshaft damage. The dealer also verified that the engine is inoperable and requires full replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer: No, the engine failed while in motion and was taken to the closest mechanic. Inspections by an insurance representative or manufacturer representative can be arranged. The vehicle and damaged engine remain available for further examination. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" Answer: No. There were no warning lamps, diagnostic messages, or drivability symptoms prior to the catastrophic engine failure. The failure occurred suddenly and without any advance indication. All service records are available

I am writing to formally request a review of my vehicle-??s eligibility for Recall N212332040. I own a 2021 Chevrolet Tahoe, which is currently not listed under the affected vehicles for this recall. However, based on the recall description and the symptoms outlined, I believe my vehicle experienced related issues and should be considered for inclusion. While driving down the highway my vehicle experienced power failure leading to a full stop in the middle of the highway, resulting in a 9-1-1 call due to safety concerns for myself and oncoming traffic. The car was later diagnosed with the fuel pump module failure that other vehicles within the same year & model experienced, which were included in the recall. Why mine wouldn-??t be included is quite confusing. I respectfully ask that your team investigate whether my Tahoe meets the criteria for Recall N212332040. On 10/20 I sent in a request to the GMC recall department & on 11/11 I was denied anything further. I appreciate your attention to this matter and your commitment to vehicle safety.

While driving my vehicle shut down. It will not longer crank. Had to have it towed. I am told that it-??s the fuel pump driver control module. I carry my two children in this vehicle daily. This could have ended very badly. Now not only is my family without a dependable vehicle, I am going to be out a lot of money on an issue that is already a common issue.

The fuel pump went out. We were driving, about to enter traffic, and the engine shut off. It would not restart, and we had to have it towed to a mechanic's shop. The fuel pump control module was removed and replaced.

I just had to buy a fuel pump control module 2021 Chevy Tahoe high country that would crank over, and not start. Per internet, this part is on a million car part failing. I found on internet that it should be replaced at no charge. I was stuck at house and had a friend check with a OB2 tester and it showed failure. I called 2 dealers and mentioned recall and was told they knew nothing about. Yet on September 11th of this year, GM was well aware! recall #252516900. I had to get a ride and go purchase at a GM dealer. And paid $69.09 with tax. Part number #13554821 GM 03900 module 03.900. And could have been a serious problem if I would have been driving or stuck or somewhere. Costly to get towed and no car to drive. Im handicap and can't be without. But for a dealer to charge. And play dumb since I was going to have to buy and change at my home. Want my money back for a no charge part.!!!!!!!!!

Was in stop and go traffic. Car suddenly said -??conditions not correct for shift-?? and engine died. The car would not turn on and it could not be put into neutral therefore was stuck in the lane stopping all traffic on the NJ turnpike. It created a safety issue for that reason as there was no way to move the car to a safe place until a tow truck came and had to drag it onto the bed. I have since had it repaired at a local shop not Chevrolet dealer and was told it was fuel pump failure. There was no warning or any other symptoms in facet I had just had an oil change a week prior. Had there not been stop and go traffic and I was going the speed limit (60mph), there could have been a major accident and injuries.

- Kings Park, NY, USA

The fuel pump control module failed while I was driving. My vehicle shut down in the middle of the road. I was unable to put my vehicle in neutral to move it off the road. A tow truck had to come in order to get it out of traffic. The next day we had it towed to the dealership who replaced the fuel pump control module. This is a safety issue because the car will shut down with no warning while driving. It-??s very dangerous. The second safety issue is that the vehicle becomes immovable without a tow truck. There is no accessible shift override to manually put the vehicle in neutral.

My 2021 Chevrolet Tahoe suddenly shaked and the engine shut off and on and nearly stalled on the road. I towed the car to the servicing dealer who has not been able to fix the issue. There is a national recall for the issue for the month of September 2021 Safety recall N212332040 for this issue but NHTSA has not added my car. NHTSA must include my car with the same issue and built in during the same month of the recall. The safety issue is the car will stop running and may block traffic or can be hit when it breaks down.

On August 23, 2025 while driving on a highway with my daughter in the backseat, my car gradually stalled while it was going through an intersection. It ended up stalling prior to a turn ramp onto another highway. This resulted in an unsafe condition and unsafe location as it happened without warning or any alerts prior to or during the drive. The Tahoe was towed to the dealership service repair shop (Hendrick Chevrolet in Cary, NC) and was found to have a fuel pump control module failure requiring replacement (replacement: FP-number 13554821, module 3.900). The dealership service department acknowledged this is a part failure on the manufacturer end; however, mentioned this is a safety bulletin, but not a recall for the part. Due to the Tahoe being outside of warranty timeframe, this ended being an out of pocket expense. The service staff told us there were four other Tahoe vehicles waiting for this part at the dealership, and we waited over a week to obtain the part as it had to come from the manufacturing line. Due to the timeframe for repair (>1 week), we had associated rental car payments that was not provided by or covered by the dealership/manufacturer.

I own a 2021 Chevrolet Tahoe High Country (VIN: [XXX] ). My vehicle is subject to Recall #N252494000 (NHTSA #25V274) concerning the L87 engine and potential loss of propulsion. On [XXX], I received a -??Low Oil-?? warning for the second time within a few months. This recurring issue matches the recall description. I contacted my local dealer, Kramer Autoplex (Livingston, TX), who confirmed the recall but stated no remedy is available. I am deeply concerned about safety, as the engine may suddenly lose power or sustain damage, leaving me and my family stranded or at risk of a crash. At this time, I have no assurance that my vehicle is safe to drive, no remedy is being offered, and I have already incurred expenses related to monitoring this issue. I am requesting NHTSA-??s support in ensuring GM provides an expedited fix or interim assistance for affected owners.

The fuel pump power control module went-out, and my 2021 Chevrolet Tahoe would not start. The fuel pump power control module part number is 13554821. That part is not subject to any existing recall. However, part number 13544060, fuel pump control module, for 2021 Chevrolet Tahoes is subject to recall N2123320240. The parts appear to be almost identical when you compare diagrams. locations, and pictures on-line. I would like to request that part number 13554821, fuel pump power control module, be added to the recall. Thank you,

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. the ntire 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.

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.

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.
