STRUCTURE:BODY, UNKNOWN OR OTHER
The 2026 suburban has a loud wind noise coming from the driver window and door side and the passenger side . The wind noise in abnormal and very high and it could be the weatherstripping and the door stripping and latch because the driver door needs a hard push to close completely but there is wind noise coming from the driver and passenger windows and doors . This create a safety issue that the doors if not sealed properly and the could open while driving on the highway . Also for a vehicle that has a price tag of 100,000 dollars the door seals and window seals should work up to standard and not be loose or defective and cause a very high wind noise . The safety issue is the driver door or passenger door can open while driving and cause an accident . This is a manufacturing defect that GM NEEDS TO ADDRESS urgently

ENGINE, POWER TRAIN
On Friday, March 13, 2026, while traveling at approximately 60 mph on the highway, my 2021 Chevrolet Suburban equipped with an L87 6.2L V8 engine experienced a sudden and complete loss of motive power. The failure sequence began with a dashboard warning prompting me to "press the start button again," followed immediately by the vehicle shifting into neutral without any driver input. Despite repeatedly pressing the accelerator, the vehicle continued to decelerate and could not re-engage drive. A second dashboard warning displaying "engine recall" then appeared mid-incident. Subsequently, the rear wheels locked, forcing the vehicle to coast to a complete stop on the hard shoulder without any brake input required from the driver. Upon coming to a full stop, the start button continued flashing with repeated prompts to press it, the vehicle lock emblem illuminated on the dashboard, and the vehicle became fully and mechanically immobile, unable to shift out of neutral or transition into any other gear. The engine could not power the vehicle at all. My safety and the safety of other motorists were directly and seriously endangered, as the failure occurred without warning in the middle lane of an active highway at highway speed, leaving the vehicle unable to maneuver or accelerate out of harm's way. A responding police officer confirmed the road hazard on scene and remained present to protect the vehicle and occupants while we awaited assistance. The AAA tow truck operator independently concurred upon arrival. The vehicle was transported to Classic Chevrolet, Grapevine, TX, the same day and is currently awaiting full technical inspection by the dealership's service team; an official mechanical diagnosis remains pending. The dealership service advisor has verbally confirmed awareness of an active engine and powertrain/transmission recall affecting this vehicle. The failed component — the L87 6.2L V8 engine and associated drivetrain — is available for inspection

ENGINE
While driving home from Costco with my entire family in the vehicle (4 children and my pregnant wife), I noticed the engine misfiring while traveling on Interstate 80 and mentioned to my wife that something felt off with the vehicle. After exiting I-80 onto Route 46 East at the Denville exit, the truck reached the first traffic light where the vehicle rumbled violently, shook, and completely shut off. The engine would not restart. Dashboard lights illuminated but the engine would not turn over, and the hazard lights would not activate. This created a dangerous roadside situation with traffic approaching from behind at approximately 50 MPH. I exited the vehicle and stood in the roadway directing traffic to prevent an accident while my wife attempted to restart the vehicle and called 911. Police arrived and a tow truck was dispatched. The tow truck driver attempted to jump start the vehicle, but it would not start. The vehicle had to be winched onto a flatbed tow truck.

ENGINE
While driving the Engine warning light, service ESC light, and collision light all came on and an engine knock started. I also experienced a loss of power at the same time. Car was taken to local Chevy dealership for evaluation and repair. Dealership advised that they dropped the oil and found metal shavings in the oil. After further investigation, we were advised that it was a crankshaft connecting rod failure. We have an extended warranty and were waiting to hear back on repair coverage. GM denied the repair as this vehicle is not part of the active recall. Our warranty company also denied the repair stating we did not have adequate records of oil changes. Receipts for oil and filters were provided.

The contact owns a 2020 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle stalled. A passerby helped the contact to push the vehicle into a parking lot. There was no warning light illuminated. The contact left the vehicle in the parking lot. The following day, the vehicle restarted as intended. The contact stated that on a separate occasion, the vehicle failed to start. The Push to Start button occasionally became stuck, and the contact continuously pressed the button to release it. The vehicle was towed to the dealer, but no cause for the failure was found.

Rear Axle is grinding. Took vehicle into dealer and it is the well documented rear axle issue but this vehicle is not included in a recall. The differential fluid was replaced and figure 8s were done but there is still grinding. The rear axle also drags at times when in auto 4wd. The dealer said the next step would be to replace the axle. This is the issue: Differential Noise/Failure: Reports indicate a rubbing noise while turning, often attributed to the rear differential. In some cases, the entire rear differential has required replacement.

In April of 2022 with 26k miles my vehicle had its first engine failure, Chevrolet dealership had to replace engine lifters due to a known engineering defect with the 2021 6.2 L87 engine. Now in late February 2026 with 80k miles my engine has locked up and requires a brand new engine replacement. For some reason, even though this is a L87 6.2L 2021 engine it is not part of the broader recall for this exact same engine failure for the same engine year and model.

In several separate unreplicable instances, the vehicle has turned off while driving, once on the highway, once on my street, once turning across heavy traffic, and others. I've almost died a couple times and I've taken it to the dealership several times, they have Not been able to find anything wrong with it and have been unable to replicate the issue. The engine has been replaced, and it was happening before and since. My 2023 is also doing the same thing.

SUSPENSION
Unmodified 2022 Chevrolet Suburban with 53K mi, driving 25 mph on paved county road. Without warning the upper ball joint on the right front side sheared off. There were no sounds, no bumps or grinding, truck is routinely maintained, cleaned and inspected - this was out of the blue. If we had been going faster it could have been a disaster. The dealer confirmed it is the upper ball joint. Significant mechanical damage has included the upper control arm and drive line (4wd). We are working with GM to get this repaired. It certainly seems like a Serious Safety issue. I have seen many reports of this problem.

The dashboard in 2007-2014 gm trucks and subs break apart. These can shatter when in an accident. There is insufficient bracing and supports to keep the dashboards from cracking and coming apart in pieces. Only remedy is to replace the dashboard or get an aftermarket cap that may or may not hold during an accident. Especially when the airbags is deployed.

Complete and sudden failure of the L87 V8 engine at 70 mph on the highway. Had to maneuver to the right shoulder and coast to a stop. Engine was seized and would not restart. Waited 4 hours on a dangerous highway for a tow truck which took the Chevy Suburban 200 miles to my home Chevrolet dealership. They have ordered a new engine but it is on backorder so no ETA. Vehicle was built 06-26-2024 and has not been recalled so Chevy says I do not get the extended warranty on the replacement engine.
