ELECTRICAL SYSTEM
My vehicle received a software update which has caused my OnStar (safety) option to malfunction and has stopped working properly. There is an active recall for some vehicles but for some reason my specific year is not listed as one of the years for recall but has the exact issue.

ENGINE
The vehicle suffered complete internal engine failure due to a snapped timing chain on startup. The vehicle turned over via the starter motor but failed to start. A professional diagnosis confirmed the broken timing chain caused extensive valve-to-piston damage, requiring a full engine replacement. This failure appears to be a direct consequence of the known 6.2L L87 V8 engine crankshaft and connecting rod manufacturing defects. Severe mechanical resistance or violent rotational harmonics at the crankshaft level place un-engineered stress on the timing drive system, causing the chain to snap under startup torque. All broken components are preserved and available for inspection. The defect creates a severe risk of sudden, total loss of propulsion while driving. Had the compromised timing chain snapped at highway speeds rather than on startup, it would cause immediate engine seizure, a sudden loss of power steering, and a loss of power brake vacuum assist. This leaves the driver unable to accelerate or safely steer out of active traffic, creating an extreme risk of a high-speed crash.The broken timing chain and total engine destruction were officially diagnosed and confirmed by professional automotive repair technicians.The damaged components have been inspected by independent repair representatives. The vehicle has not yet been inspected by General Motors because this specific VIN is excluded from the current recall scope. There were no warning lamps, check engine lights, or diagnostic trouble codes (DTCs) prior to parking the vehicle, and no outward symptoms of severe engine stress were present until the complete no-start failure.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On [XXX], while driving near Mammoth Mountain, California (Highway [XXX]), the vehicle suffered a sudden, severe engine malfunction. The engine began misfiring violently, accompanied by a loud, mechanical clacking noise, and experienced an immediate loss of propulsion power. This mechanical failure left my family—including young children—completely stranded on the side of a mountain highway in a secluded wilderness area with dropping temperatures (39°F) and active local wildlife Because the vehicle could not safely maintain highway speeds or generate sufficient power, it created an immediate and severe traffic safety hazard, forcing us to secure emergency transport for the vehicle. Which took 4hours for someone to come out to the secluded hwy on a holiday weekend. Dealership Diagnostic Findings A formal inspection conducted by a certified General Motors dealership (Michael Hohl Motor Company) confirmed the following: Symptoms: Gas engine diagnostic confirmed "Misfire, and clacking noises coming from passenger side of the motor." Diagnosis: Cylinder Head / Valve / Lifter / Lash Adjuster failure. The dealership documented a collapsed lifter and recommended a complete engine tear-down to inspect lifters and pushrods for wear or bending.

POWER TRAIN
On September 19, 2026, while traveling approximately 30 mph, the vehicle experienced a sudden, hard shift. The check-engine light then illuminated. I pulled over as soon as it was safe to do so. After stopping, the vehicle would not shift into reverse and entered limp mode. The transmission malfunction created a safety risk because the vehicle’s operation and available gears became restricted unexpectedly while it was being driven. The loss of reverse also prevented the vehicle from being maneuvered normally. The vehicle was not driven after the incident and was towed from the location. The vehicle and affected components are available for inspection upon request. At this time, the vehicle is awaiting inspection and diagnosis to determine the exact cause of the transmission malfunction.

ENGINE
I am submitting this complaint regarding my 2023 Chevrolet Tahoe equipped with the GM 6.2-liter V8 engine. VIN: [XXX]. At approximately 40,000 miles, the original engine experienced a major failure and was completely replaced by a Chevrolet dealership under warranty. I have now driven fewer than 10,000 miles on the replacement engine and am experiencing a very similar engine-related problem again. The vehicle is currently back at the Chevrolet dealership being inspected and repaired. This is extremely concerning because the original engine failed at only approximately 40,000 miles, and the replacement engine has developed a similar problem after fewer than 10,000 miles. The GM 6.2-liter V8 has been the subject of numerous reported engine problems and complaints, and I believe this repeated failure warrants NHTSA’s attention. I am concerned there may be an underlying or recurring defect affecting these engines that has not been adequately addressed. I am also concerned about the potential safety implications of an engine or valvetrain failure while driving. An unexpected loss of power or significant mechanical failure could create a dangerous situation, particularly at highway speeds or in traffic. I can provide dealership documentation showing the original engine replacement, the mileage at which it occurred, and the current repair visit. This documentation establishes that the vehicle has experienced significant engine-related problems twice within a relatively short period, including a similar problem with the replacement engine after fewer than 10,000 miles. I respectfully request that NHTSA document this complaint and review whether there is a broader pattern of premature or repeated failures involving the GM 6.2-liter V8 used in 2023 Chevrolet Tahoe vehicles and whether further investigation or corrective action is warranted. Replacing the original engine did not resolve the issue, as the replacement engine has now developed a similar problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

I own a 2024 Chevrolet Tahoe RST and have experienced recurring electronic/electrical problems despite multiple dealership visits. The vehicle repeatedly displays “Open Then Close” window messages for the passenger or driver window even though the windows function normally. While driving, the infotainment screen has repeatedly gone black, causing the audio/music and audible turn-signal indicator/chime to stop working. On one occasion while stopped at a red light with the vehicle running, the infotainment screen and entire instrument cluster went blank and rebooted. The Chevrolet logo remained displayed during the restart, and the audio and turn-signal chime stopped working. The dealership has been unable to duplicate the issue but has performed software updates. The problems continue. Most recently, the vehicle displayed “Service Transmission Now — Unable to Shift Soon.” The warning disappeared. The dealership then stated the 12-volt battery was low and needed replacement before accurate diagnostics could be performed. I replaced the battery, and afterward the check-engine light came on. A complete diagnostic has not yet been performed because my appointment was rescheduled. I am concerned these recurring electrical/electronic issues, transmission warning, and check-engine light may indicate an underlying safety-related defect. I am requesting that GM formally document and investigate these concerns.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
On September 5, 2026, at approximately 7:18 p.m. Pacific Time, a 2025 Chevrolet Tahoe High Country equipped with the 6.2L L87 V8 engine and approximately 18,000 miles experienced a sudden catastrophic failure while the engine was running. There were two occupants. A distinct pop was heard. The engine immediately lost power and multiple dashboard warning lights/messages began flashing. Within approximately 20-30 seconds, smoke and an electrical-burning odor were noticed. The vehicle was shut off manually and both occupants exited. Flames were first observed toward the rear of the engine compartment. The fire spread extremely rapidly, and the vehicle was substantially engulfed within approximately two minutes and completely destroyed. The sudden loss of propulsion created a crash risk, and the rapid fire placed both occupants at risk of serious injury or death. No physical injuries were reported. The precise failed component and fire origin have not yet been determined. The vehicle had received an oil change from an independent service facility within approximately 30 days before the incident. The cause has not been confirmed by GM, a dealer, or an independent fire expert. The vehicle is involved in an active insurance total-loss claim; inspection should be coordinated promptly before the salvage is released, dismantled, sold, or destroyed. More than 100 photographs and several videos taken during and after the fire are available. A fire department report is pending. Because NHTSA Engineering Analysis EA26005 includes 2021-2026 GM vehicles equipped with the L87 engine and later-produced engines outside Recall 25V-274, please associate this complaint with that investigation and evaluate whether an L87 engine failure initiated the fire.

UNKNOWN OR OTHER, ENGINE
2021 Chevrolet Tahoe – Unexpected Shutdown/Restart While Stopped On two separate occasions, my 2021 Chevrolet Tahoe has unexpectedly appeared to shut down while I was stopped with my foot on the brake. The vehicle is equipped with Auto Stop/Start, and initially the event seems like a normal Auto Stop. However, instead of a normal engine Auto Stop/Start cycle, the vehicle appears to shut down or reset more completely. The event is jarring, and the power door locks lock/unlock as the vehicle shuts down and restarts. The vehicle subsequently restarts and I have been able to continue driving. This has now occurred twice while stopped. I am concerned that the vehicle may be experiencing an unintended stall, loss of electrical power, or another malfunction rather than normal Auto Stop/Start operation. I checked my VIN through NHTSA and it does not currently show an open recall. I am aware that certain 2021 Chevrolet Tahoes have previously been recalled for a condition that could result in an engine stall, although my VIN does not appear to be included in that recall population.

We were driving on the highway and the engine started making a ticking noise and AFM light came on. Took the car to the dealership for inspection and they said the lifter had collapsed and it would cost $1000 to tear the engine down to see if the camshaft was damaged. Asked for the estimate to replace camshaft and lifters and they quoted $10,000.

POWER TRAIN, ENGINE, FUEL/PROPULSION SYSTEM
Vehicle began making loud knocking sound XXX Towed to dealer 9/8 after holiday. They found metal in the oil and believe it needs an engine replacement. A week later I have no answers, there's no loaners available, so I am just without a car. We bought car from Zimbrick Chevy in [XXX]. It was never disclosed to us that the vehicle had an engine replacement right before we purchased. New engine lasted about 16,000 miles. Only once we saw the history of the car in the current dealership's service app did we learn about the engine replacement. This is beyond unacceptable!

AIR BAGS
I received an automated message from the vehicle stating to service the safety restraint system. I took the car to the local dealer and they ran a diagnostic review. There is a TSB for the vehicle and they say that the problem is coming from the overhead console part number 86575239. This part is not available anywhere. I contacted General Motors and requested assistance. All they have done is escalate it to the parts delay team. When I called today, all they say is they do not have any information available. They can’t even say when the part will be in stock. The dealership was unable to say that the airbag system would work as required or not. The car is unusable due to the passenger air bag system fault.

Our Tahoe was included in the recall. The dealership inspected it, found no issue at the time, and told us to switch to a different oil viscosity, which we did. This vehicle has only ever been serviced at a Chevrolet dealership. On August 20th, while driving on the highway, the engine shut off without warning and we had to coast to the shoulder. We attempted to restart it several times, but the engine would not hold an idle. After shutting off all accessories, including the A/C and radio, the vehicle finally started. We brought it back to the dealership for inspection, and once again they could not find any issue. Today, September 14, 2026, we heard loud clanking coming from the engine. We pulled over immediately and had the truck towed to the dealership. At this point, we believe the engine is no longer serviceable and will need to be replaced. We do not believe the change in oil viscosity is an adequate fix for the 2022 to 2024 6.2L engines covered under the GM recall, including the one in our Tahoe. An engine dying without warning at highway speed is a serious safety hazard, and we were fortunate it didn't end in a collision.
