ENGINE
While coming to a stop on a highway, the engine started running very rough, shaking the vehicle constantly, and the check engine light came on and the ESC failure notice came on. We brought it to an independent repair shop that ran diagnostics and recommended the vehicle needed a new engine and should not be driven for risk of it seizing. They introduced us to the fact that there was a GM recall on this particular engine and production year. Upon taking the vehicle to the local Chevy dealership, they suggested that we first repair a failed cylinder lifter, but that there may also be crankshaft issues, but that it would be costly to determine this for sure and that it was likely more cost effective to replace the whole engine than approach the repairs in order. They also confirmed our VIN was not part of the recall so the replacement engine would be our responsibility. We had the engine replaced back at the independent repair shop. Given the recent recall expansion, I wanted to submit this, as it seems that a broader number of vehicles within the production years of this engine should be considered included in this recall.

ENGINE
operating vehicle as usual, in drive, when engine spontaneously turned off. Alerted by system to "push button to start again" and put me in neutral. Extremely dangerous while the vehicle was in motion. This is the exact same thing I read about in a 2025 recall of 2021-2024 model year Suburbans and other vehicles. Mine is a 2022 Suburban.

UNKNOWN OR OTHER
Found that SOS nor OnStar buttons were not working. Dealership checked telematics control module was failing. Service bulletins were issued for wide spread failures, however no recall notices were issued. The module failure will also prevent notifications in the event of a traffic crash. Estimated repair cost $900. A true safety issue that should require a recall.

ENGINE
My 2023 Chevrolet Suburban equipped with the 3.0L Duramax diesel engine (LM2) has experienced a recurring engine oil leak involving the rear main seal/lower timing cover area. The vehicle has required repeated dealer repairs for substantially the same oil-leak condition, including major engine-related disassembly, but the leak has returned after repair. This is a safety concern because failure of the rear main seal or lower timing cover sealing system can result in loss of engine oil while the vehicle is being operated. A significant oil loss could potentially cause loss of oil pressure, engine damage or engine failure and resulting loss of propulsion while driving. Leaking engine oil also has the potential to contact hot engine or exhaust components, creating an additional safety concern. The problem has been inspected and confirmed by authorized GM dealerships and documented on multiple repair orders. This does not appear to be an isolated occurrence on this vehicle because substantially the same engine oil leak has required repair more than once. GM has previously issued service information, including Bulletin PIP5795, concerning rear main oil leaks on 3.0L LM2 Duramax engines where the rear main oil seal may move or become severely shifted out of position in the timing chain lower cover. I am concerned that repeated repair of this condition may not adequately address the underlying cause and that the oil leak could recur while the vehicle is being driven. I am requesting that NHTSA review complaints and repair data involving rear main seal/lower timing cover oil leaks on GM 3.0L Duramax-equipped vehicles to determine whether a broader safety-related defect exists.

The dealer was notified of the failure and advised the contact that the spark plugs might need to be replaced. The contact stated that while driving and coming to a stop, the vehicle chugged, lunged forward, made an abnormal clicking sound, and almost struck another vehicle.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, EXTERIOR LIGHTING
1) Both screens (driver display and infotainment) go black intermittently. Sometimes the infotainment comes back on, however, you cannot use all the buttons. The hard buttons under the screen for climate control (aside from the on/off ) wont work. The climate will automatically go to 76 degrees on Max Defrost. The rear climate will shut off when this happens. It also causes the radio controls on the back of the steering wheel to not work. 2) It is extremely dangerous to not have a visual indicator for the speed at which I am driving. It is also dangerous to be driving with no AC and instead 76 max defrost, in triple digit temperatures. Especially with small children and a newborn baby. 3) The car has had several repair attempts by a Chevrolet Service department. 4) When it happens its sudden. No warnings. After it happens the Check Engine Light comes on sometimes. This started a week after the car was purchased in March 2026. It is still occurring now in August 2026.

POWER TRAIN
The transmission failed suddenly and without warning. When I Went to pull out from a stop sign with cross traffic doing 55 mph, the vehicle shuddered and stopped pulling. We barely had enough momentum to get out of the way of oncoming traffic at the last second. The oncoming traffic had to brake and honked. After reading online, this is a common issue with the 6l80 transmission torque converters being a failure point and the fluid temperature being too high. Gm has a service bulletin for a lower temp bypass valve but there is no recall and these units are failing by the tens of thousands.

ELECTRICAL SYSTEM
The telematics control module in this vehicle failed. A dealer diagnostic scan on 03/09/2026 at 67,839 miles documented the following active and history codes: U0198 Lost Communication with Telematics Module, reported independently by the Radio, Body Control Module, and Instrument Panel Cluster Control Module; U0499 Invalid Data Received from Telematics Module, reported by the Engine Control Module; U1962 Unable to Authenticate Serial Data Message; B1A1F Ethernet Bus 4 (+) Circuit Open with a Low Voltage/High Temperature symptom; and P00FF Body Control Module Requested MIL Illumination, listed as Current. As a result, the check engine light is commanded on. All OnStar functions are inoperative, including Automatic Crash Response and Emergency SOS, which are safety systems. The OnStar button has no illumination at all. Remote functions and vehicle connectivity are dead. No warning message or notification of a module fault was ever displayed in the vehicle. The infotainment system reports “Your Software is Up-to-Date” and the Device Registration screen reports “Registered.” The last over-the-air software update this vehicle received was in August 2023

ENGINE
There is a safety recall on GM’s 6.2L V8 L87 engine model years 2021-2024. My vehicle is a 2020 Suburban with a 6.2L V8 L87 engine. My engine recently experienced the same failure as cited in the recall, but because it is outside the 2021-2024 window it is not covered by this recall. I ask that the recall be expanded to additional years where these engines are experiencing the same failure as is covered by the current recall.
