ENGINE, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
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
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.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
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.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
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.

ENGINE, ELECTRICAL SYSTEM
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.

UNKNOWN OR OTHER
I purchased a brand-new 2023 Chevrolet Tahoe. One of the key reasons for choosing this vehicle was its built-in safety and connectivity features, including the OnStar system. I also pay more than $50/month for an OnStar subscription, trusting that the service would provide essential safety functionality. Recently, the OnStar system in my vehicle stopped working. I received no warning, no service bulletin, and no notice from GM or OnStar of thhe failure or that this was a known issue. Upon diagnosis, I was informed that the OnStar module had failed and would need to be replaced—at a cost of $822 out of pocket. OnStar is a core safety feature that GM actively promotes as part of the vehicle’s value and security. For such a critical system to fail in a vehicle that is barely two years old is unacceptable. I believe this constitutes a product defect that GM/OnStar should be held accountable for, especially since multiple consumers are reporting similar issues on public forums. Most of all I had no indication in the vehicle of the failure; there was no check engine or issue light indicating a failure. When I called onstar the only explanation I got was that I should have noticed that the onstar light was out. That’s not sufficient for a safety item you expect to work like the breaks.

ELECTRICAL SYSTEM
I along with many owners have experienced the widespread OnStar/telematics module failures in the current generation Tahoe and GM vehicles, which cause onboard system outages like navigation, safety alerts, city emergency services, cellular connectivity, Android Auto/Apple CarPlay, and even instrument cluster functions sometimes going offline. The part is often back-ordered with no ETA, while GM denied warranty coverage causing the owner to pay for the replacement part and all labor.

FUEL/PROPULSION SYSTEM
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,

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.

ENGINE, ELECTRICAL SYSTEM
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)

SERVICE BRAKES
There was a recall in 2019 (NHTSA Recall No. 19V645000) on certain GM vehicles for vacuum pump failure, which could affect braking and engine performance. The fix usually involved reprogramming the ECM to improve how the brake assist system operates - not necessarily replacing the vacuum pump unless it had already failed. My local dealership did the reprogramming but in 2025 the vacuum pump totally failed and left my vehicle stranded on the interstate. I had to have towed to a mechanic shop and the inside of the pump had broken into 3 pieces. So I had to have the vacuum pump replaced. During this time my car did not have brakes and put me and surrounding vehicles in a very dangerous situation. The mechanic gave me the broken part to show the dealership. The dealership said there isn’t anything they can do for assistance as I am out of warranty. There was a message that came up that said to service the braking system right before they stopped working.

While driving on the expressway I heard a rattling noise coming from my undercarriage, by the time I got off my exit the sound got louder, I attempted to make it home and when I pulled in my driveway, and popped the hood, fluid starting pouring out the bottom as well as splashed on other components. Upon further inspection it was determined that the fluid was coolant. There was no dashboards lights or warning signs indicating that something was wrong or that my car was at risk of overheating. I had the vehicle towed to an auto repair shop and the following was diagnosed and repaired: •Water pump •Cooling System •Engine Water pump •Engine Coolant thermostat housing assembly. •Serpentine Belt
