FUEL/PROPULSION SYSTEM, ENGINE
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.

[XXX] # [XXX] VIN = [XXX] MAKE ; Chevrolet Tahoe 2021 RE : I received a recall affects certain 2021-2024 models equipped with the 6.2L V8 L87 engine. The defect involves the connecting rod and/or crankshaft engine components, potentially leading to engine damage or failure. On March 2025, My Tohoe completely stopped while I was driving. My SUV was towed to Bomnin Chevrolet in Manassas Virginia. They diagnois was crank shaft damage leading to engine failure. My SUV was in the dealership for 2 weeks while the engine was replaced. I spent a total of $ 15,027.20 to fix my car for that problem. I called GM recall about this problem. I was informed that the recall was for only certain vehicles. Not my SUV. I am concerned that my SUV was affected by faulty crank chaft. I had to replace the engine. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, BACK OVER PREVENTION: WARNINGS, ELECTRICAL SYSTEM
Failed OTA Update to information center (Radio) has caused radio unit and screen to become inoperable. Blinkers do not sound when on, warning sounds when backup camera are in use no longer work, along with cross traffic warning due to this. It should be noted we did not consent to the OTA update, and would have not wanted the update as it has caused damage to this system. GM know this is an issue and has refused to fix this.

ENGINE AND ENGINE COOLING
The contact owned a 2021 Chevrolet Tahoe. The contact stated while driving approximately 60 MPH, the check engine warning light illuminated, and the vehicle started losing motive power. The contact stated there was an abnormal ticking sound coming from the engine compartment. The contact stated that the vehicle slowed to approximately 10 MPH with black smoke coming from the exhaust pipe. The contact was able to drive the vehicle to a dealer. The dealer diagnosed the vehicle and determined that the engine connecting rods had failed and needed to be replaced. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The vehicle was repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 85,000.

ENGINE
On April 25th, 2025 while traveling on Interstate 20 at 70+mph speeds with my children in my vehicle and 30 weeks pregnant, with no indication of an issue my 2021 Chevrolet Tahoe suffered catastrophic engine failure. There was zero warning from the vehicle including noises/electronic display warnings that this was fixing to occur. In the middle of going 70+mph surrounded by traffic on a busy interstate the vehicle just shut off completely. I was able to use what momentum I had from my speed to get on to the shoulder. However, the failure prevented me from being able to turn on my signal to alert other drivers of my merging and prevented the use of my emergency flashers to signal once on the shoulder immobile. The vehicle would not start up again after that, and I had to call a tow truck to take my vehicle to the nearest certified Chevrolet service center. When the tow truck arrived the vehicle would not even shift into neutral allowing them to load it without potentially causing more damage. It had to be drug with the wench in park onto the tow truck bed. Once at the nearest service center I was told it would be up to 3 weeks + before they could do a diagnostics. I was 14 hours from home when this happened, and now had to pay to have my Tahoe towed 14 hours back to the service center near my home. On May 8th the failure was determined to be caused by this recall, specifically the crankshaft. The dealership has lied and said they've ordered a new motor and it came in, then called to tell me they ordered the wrong motor. They said they ordered the correct one and it would be in within 14 days, and that was 25 days ago. They called today June 16, 2025 to tell me there is still no update on when my engine will ship to complete this repair. The dealership has also refused to assist me with any loaner vehicle or rental assistance even though GM has told me I am entitled to it under this recall. GM has moved my case to Parts Delay team and I still have not been contacted.

ENGINE
While starting from a stop the engine stuttered and resulted in a major loss of power. Luckily this occurred pulling out of our driveway on to a quiet neighborhood street. Several warning lights and messages went off including the engine and transmission system warning, “service ESC”, “Service Traction Control”, and the emission system warning. After driving it to the dealership at 30mph since the shaking and banging noise was so bad, the dealer diagnosed it as a cylinder 6 caused by a failed lifter and lifter rod. Resulting repair involved lifters and rods in that same bank at a $3500 repair. The vehicle was just over 4 years old with 79,250 miles.Repair invoice available upon request.

AIR BAGS, STEERING
The safety system needs serviced/repaired and the alert has been present for months, and investigated by GM licensed dealership but not repaired, after several requests. The safety of drivers and passengers has been neglected and the high risk for injury and death while occupying the 2021 Chevy Tahoe. Also on 06/11/2025 the EPS Power Steering system failed, with the system alert showing up on the driver's dash. This is a cause for major concern and is noted that 2021 Chevy Tahoe vehicles have an outstanding recall for those affected. The licensed GM dealership was contacted on 06/12/2025 and again, denied the repair and/or ability for the vehicle to be operated safely. The Tahoe has been taken to the shop over the last 12-16 months and as of this day, occupants of this vehicle are at very high risk for injury and death due to the service safety system alert and the failed EPS system. I am compelled to take additional action, to prevent injury and death unless these issues are able to be immediately resolved.

Recall issued by GM (N25249000/NHTSA 25V274) on powertrain/crankshaft and took car to GM dealer and was refused service or safety inspection. Told that they were told by GM not to inspect or service vehicle at this time. How can a safety recall be issued but GM not be ready to inspect or remedy issue?

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
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

EXTERIOR LIGHTING
We were driving our 2021 Chevrolet Tahoe (purchased Dec 2020; odometer currently right under 40,000 miles) out of town this past weekend and I noticed the headlights were not illuminating the road ahead very well once the sun went down. They seemed like they were pointed down and when i turned on the high beams, those were also lower than how the low beams are usually pointed. We were stuck in the middle of nowhere and I persevered with low lighting onto our destination. After researching the issue on the internet days later, I found a Tahoe Owners' forum/thread [XXX] ) where several other 2021 Tahoe owners had experienced the exact same issue as ours had. The culprit appears to be a sub-component of the headlight adjuster mechanism, but GM/Chevrolet does not offer a replacement for either this small white plastic piece that is failing and the only repair option they have for this issue is complete replacement of the entire headlamp assembly ($1,350 MSRP). This is a dangerous problem that occurred randomly on a vehicle with low mileage and appears to potentially be a common failure for other owners of the same headlamp design. I have not taken this vehicle into the dealership for inspection, as I expect they will only replace the entire headlamp assembly for $$$$.

ENGINE AND ENGINE COOLING
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while her husband was driving 40 MPH, the "Service Stabili-trak Soon" message was displayed on the instrument panel. The contact stated that there was an abnormal knocking sound coming from the engine and the contact's husband pulled over and restarted the vehicle. The contact stated that after the vehicle was restarted, the failure persisted. The contact's husband pulled into a gas station and called an independent mechanic. The mechanic advised the contact's husband to safely drive the vehicle home and to then take the vehicle to his shop the next day for a diagnostic test. The vehicle was driven to the independent mechanic and was diagnosed, and the contact was informed that cylinders #1 and #7 were not functioning as needed. The contact was then informed that the engine lifters needed to be repaired. The manufacturer was notified of the failure and parts were ordered to repair the vehicle. The vehicle remained in the possession of the mechanic and was not yet repaired. The failure mileage was approximately 75,400.

FORWARD COLLISION AVOIDANCE: WARNINGS, ENGINE
On April 25th, 2025 we were taking our kids to their after school activities when the SUV started to shake, and accelerate very fast by barely pushing the gas pedal, the ETS light along with the forward collision warning also appeared on the dashboard along with the check engine light. This prompted my husband to get our vehicle towed to the nearest shop close to the street where our vehicle started having problems. After several days of diagnostics the shop let us know our vehicle needed the following repairs: Bank One lifters replacement, head gasket service, and a water pump replacement, we ok'd the repairs. Although these components were replaced, we were informed on May 15, 2025, that the vehicle continues to misfire and now requires a camshaft replacement as well. The total cost of the repair has now risen from $5,182.16 to $13,549.79, which is a significant financial burden as the vehicle is just outside of warranty coverage. We are aware that there is an active recall covering similar issues for 2021–2024 Chevrolet Tahoes equipped with 6.2L engines. However, our 5.3L engine model is experiencing the same mechanical failures, including misfires, knocking noises, low RPM idling, and performance degradation. There is growing evidence that the valve lifter issues are not limited to the 6.2L engine variant. Our experience—and the experiences of others reported online—suggests that the 5.3L L84 engine may also suffer from the same design or manufacturing flaws. We respectfully urge NHTSA to investigate whether this issue warrants expanding the scope of the existing recall to include the 5.3L engine models, and we ask that GMC/General Motors be encouraged to provide assistance. Given the severity and known pattern of these issues, we believe GMC should cover at least 75% of the repair costs, or ideally, offer to perform the repair at no charge. Thank you for your time and consideration.
