Fuel/propulsion system, Sep 2, 2025
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 am writing to formally document serious engine defects I have experienced with my 2021 Chevrolet Tahoe equipped with the 5.3L L84 V8 engine. 1.Crankshaft Failure oMy Tahoe suffered a catastrophic crankshaft failure that required major repair/replacement. oI am aware that GM has recalled certain vehicles equipped with the 6.2L L87 engine for crankshaft and rod-bearing defects. oBased on my experience, the same or a very similar defect has also occurred in my 5.3L engine, which is currently not included in that recall. 2.Valve Lifter Failure oIn addition, my vehicle has suffered from valve lifter collapse—a well-documented problem in 2021–2022 GM trucks and SUVs with both the 5.3L and 6.2L engines. oThis caused severe misfiring, drivability issues, and expensive repair needs. Why this is a concern: •Both failures occurred well before what would be expected of a modern engine. •The crankshaft failure raises a safety risk: sudden loss of propulsion while driving could lead to accidents. •The lifter issue is widely reported by other owners and has been the subject of GM service bulletins. •Taken together, these problems suggest systemic defects in the 2021 Tahoe’s 5.3L engine that have not been adequately addressed by GM. Requested Action: •I ask GM to extend recall and warranty coverage to include the 5.3L L84 engine in addition to the 6.2L L87. •I ask NHTSA to consider investigating whether the scope of the current 6.2L recall should be broadened to include 5.3L engines, given failures like mine. •At minimum, I request assistance in covering repair/replacement costs for both the crankshaft and lifter defects, which are clearly not due to normal wear and tear. Vehicle details: •Year/Make/Model: 2021 Chevrolet Tahoe •Engine: 5.3L V8 L84
Vehicle speed control, Engine, Forward collision avoidance, Sep 2, 2025, crash
I drive a 2021 Chevrolet Tahoe. This occurrence has happened on three separate occasions and each time it was raining outside. The first occurrence, my vehicle was running and parked in the rain after driving approximately 5 miles. While parked my check engine light came on with a series of warnings: service ECS, service traction control, forward collision system unavailable, reduced acceleration drive with care. Two days later it went away. The second occurrence, I was driving in the rain for approximately 22 miles and briefly parked with my vehicle running. I then turned out of a parking lot and began to accelerate to speed up and the check engine light came on along with all the same messages, this time my vehicle acceleration had seized and wouldn’t go faster than 30 MPH. I slowly drove back to the parking lot and turned the vehicle off to let it sit, disconnected the battery and reconnected, and the issues went away. The third occurrence, I was driving on the highway in the rain for approximately 10 miles, I went to merge into a right hand lane, I took my foot off the acceleration peddle to slow down for the merge and as I slightly turned the wheel to the right, my vehicle spun out three times, throwing the back end of the Tahoe into the inner highway wall, which spun me again to face the right direction, next to a highway exit. I then went to accelerate to exit the highway but noticed my vehicle would only coast and realized my engine had cut out at some point. I started the vehicle and exited the highway and parked in a parking lot only feet away from the exit. After I parked I noticed all the same warning lights came back on. Each occurrence happened on [XXX], [XXX], [XXX]. My vehicle was towed to Gunn GMC Collision Center in Selma, Tx and will be looked at on September 3, 2025 around 8:00am.

Fuel/propulsion system, Sep 1, 2025
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.

Power train, Electrical system, Engine, Aug 30, 2025
The affected systems are the power train, engine, and electrical. My 2021 Chevrolet Tahoe experienced failures consistent with GM Technical Service Bulletin 21-NA-149 (engine wiring harness chafing) and the conditions outlined in Recall N232404190 (valve body failure, November 2024). Beginning in March 2025, the vehicle displayed warning lights and messages including Check Engine, Traction Control, Service Transmission, and limp mode (Reduced Acceleration – Drive with Care). The vehicle shifted erratically, lost power, and occasionally failed to accelerate, creating a serious safety hazard at highway speeds. These problems were documented at AutoNation Chevrolet South Clearwater, where multiple diagnostic trouble codes (P0700, P0717, P2714, P2716, P0706, and U-codes) were recorded but not properly investigated. No test drive was performed despite being claimed by the service technician, and the applicable TSB was not referenced. By July 2025, the condition worsened into a complete transmission failure, with additional codes (P0700, P077C, P17F6, P17FB, P1872). The dealer’s estimate required a full transmission replacement at nearly $10,000. GM reviewed the case through its internal Policy Evaluation Tool and increased goodwill assistance from 15% to 40%, while AutoNation contributed only $500. GM’s partial contribution confirms the defect is recognized, yet this VIN remains excluded from the official recall. This issue placed my family and other motorists at significant risk, as sudden loss of power and shifting failures occurred during normal driving conditions. Dealer records, GM documentation, and photographs of warning messages are available. I request that NHTSA expand Recall N232404190 to include affected VINs such as mine, since the symptoms, diagnostic codes, and confirmed failures match exactly what GM has already identified as a known safety issue.
Power train, Electrical system, Engine, Aug 30, 2025
The affected components are the electrical system, engine, and power train. In March 2025, my 2021 Chevrolet Tahoe displayed multiple warning lamps across the dash, including traction control and check engine lights. The vehicle shifted erratically and sometimes entered limp mode. I brought the vehicle to AutoNation Chevrolet South Clearwater for inspection. The dealer replaced the battery, dismissed my concerns, and stated that a test drive was performed, but the mileage in and out on the invoice was identical, showing it never actually occurred. Diagnostic trouble codes (P0700, P0717, P2714, P2716, P0706, and multiple U-codes) were present but were not fully investigated. A GM Technical Service Bulletin (21-NA-149, December 2022) covers these exact symptoms (caused by engine wiring harness chafing), but it was never referenced or applied. Because the problem was not addressed, the condition worsened. By July 2025, the vehicle suffered a complete transmission failure. At that point, the dealer confirmed the issue, documenting transmission slipping, shuddering, noise, and additional codes (P0700, P077C, P17F6, P17FB, P1872). GM increased its goodwill contribution from 15% to 40% of the $9,925 repair cost, while AutoNation offered only $500 despite their role in the missed diagnosis. Safety Risk: My family and I were at risk each time the vehicle stalled, lost power, or shifted erratically while driving, including at highway speeds. These failures created a significant risk of collision. The drivability problem was not properly confirmed in March 2025 despite multiple codes being present. By July 2025, the dealer acknowledged and confirmed the transmission failure. The vehicle remains available for inspection, and I have retained all invoices, diagnostic reports, and communications with GM and the dealership.

When driving the car just stops losing power then the car immediately shuts down and stops driving. I had to call a tow truck when it’s taken to the dealership the fuel pump power control module is faulty. This is a 2021 Tahoe they had to replace the fuel pump, power control module, and this vehicle should not have to be replaced. Chevrolet/GMC knows that these modules will make the vehicle stop wherever it is driving. I happen to be on a freeway going 70 mph and could have been killed. They have not put a recall out to have these modules replaced in any SUV. This is a danger for any driver on the road. This is a lawsuit waiting to happen for people. You know that they are aware this is happening because they paid for the tow and replaced this part that is not warranty now for free. Yes, great that it was paid for but thankful I did not lose my life as I could’ve been rear ended when my car shut down going that fast in the middle of the freeway I am begging that they please put a recall so no one gets injured or killed.

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.

Leaving the stoplight, all the sudden the dash read service ECM in the motor started clanking. Took it to the dealership where they told me the cam and lifters were bad and said we might as well get a new motor $17,000. And not approved by extended warranty, crooks.
Electrical system, Engine, Aug 22, 2025
To Whom It May Concern, I am writing to formally report serious defects with my 2021 Chevrolet Tahoe (VIN: [XXX] ) and to request assistance with repair costs. Approximately six months after purchase, when the vehicle had about 22,000 miles (I bought it used with around 19,000 miles), the battery and electrical system failed. I brought it to the dealer and was told there was no issue; they only performed a jump start. Two days later, the vehicle broke down in the middle of the road. I had to pay for a tow truck and replace the battery completely out of pocket. More recently, at about 92,000 miles, the vehicle developed severe engine problems. A certified mechanic diagnosed collapsed AFM lifters and camshaft damage. The repair requires OEM GM parts and costs approximately $4,500. This issue is widely reported by other GM owners with 5.3L AFM engines and is known to be a manufacturing defect, not a maintenance problem. Please note that my Tahoe has been well maintained, with oil changes always performed on time and using the correct oil and service intervals recommended by GM. Despite this, the vehicle has experienced repeated and costly failures that create unsafe driving conditions. I kindly request that GM review my case and provide assistance with covering the repair costs or reimbursement, given that these issues are the result of known defects and not owner neglect. I look forward to your prompt response. Sincerely, [XXX] [XXX] 33032 [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuel/propulsion system, Aug 12, 2025
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.
Engine, Power train, Aug 5, 2025
I am submitting this complaint regarding my 2021 Chevrolet Tahoe (VIN: [XXX] ) which has developed a severe transmission shudder at both low and highway speeds. The issue has been confirmed by my Chevrolet dealer, who provided an estimate of $5,492.18 for torque converter and valve body replacement. This failure is identical to the torque converter shudder problem documented in GM service bulletins and special coverage adjustments for other GM vehicles of the same make, model, and model year. However, my VIN is not currently included in those programs, leaving me without coverage despite experiencing the exact same defect. I believe this condition poses a serious safety risk, as the shudder occurs while driving at highway speeds, causing vibration, hesitation, and potential loss of control. These symptoms could lead to accidents if the vehicle fails to respond properly during acceleration or lane changes. Given that this appears to be a widespread defect affecting multiple GM vehicles, I respectfully request that NHTSA investigate and consider expanding any related recall or special coverage programs to include affected VINs such as mine. Please let me know if further documentation, service records, or dealer estimates are needed to support my complaint. Thank you for your time and for working to ensure vehicle safety.
