On [XXX], at approximately [XXX] while driving my 2026 Chevrolet Suburban (VIN [XXX], approximately 2,795 miles) on [HIGHWAY NAME], the vehicle suddenly lost all power without warning. The check engine light came on, all the dashboard warning lights lit up, the 4WD indicator light came on, and the steering wheel wouldn't turn, making the vehicle very difficult to control at highway speed. The instrument cluster also displayed a "Service Transmission" warning and a "Lane Change Alert System Off" message. The myChevrolet mobile app simultaneously reported "Service Now: Engine and Transmission System" and "Antilock Braking System." I was able to bring the vehicle to a stop and shift into Park. There was no crash and no injuries. The vehicle was purchased new approximately one month earlier (September 2026) and had already been serviced once by the dealer (September 21-22, 2026) for an engine oil leak (oil pan seal failure) and a front-view camera/ADAS software issue. A sudden loss of power at highway speed is a serious safety defect. The vehicle has not yet been diagnosed for this incident.

I work at an express car wash and we have had 3 2026 GMC-Chevy vehicles that have had issues with their antenna covers. There has been proven no malfunction from the car wash, yet, antenna covers are being blown off by the blowers which is potentially air - such as driving down the interstate. Warranty’s are not covering this issue for the customers. I can provide details such as pictures and video footage showing there was no malfunction to my wash, but possibly defective antenna covers.

The drivers side blind zone light illuminates in the mirror when no objects/vehicles are present. The condition happens every time the vehicle is driven since it was purchased new in July 2026. The false alerts occur frequently when driving and render the left (drivers) side alerts completely unreliable and distracting/dangerous for the driver. The vehicle also vibrates the drivers seat when trying to make left-hand turns and lane changes because the blind zone sensor is incorrectly sensing an object is present when there is not. At highway speeds these false alerts are very distracting and unsafe for the driver. The vehicle has also on more than one occasion applied emergency (very abrupt) braking when trying to back the vehicle out of our driveway, with the dashboard indicator showing an object approaching from the left (drivers side) but no object/vehicle/pedestrian is present or approaching. GM has recently issued a Technical Service bulletin about false blind zone alerts that covers some 2026 Suburbans but we are being told our 2026 Suburban is not included. That makes no sense since our vehicle obviously has an issue with false alerts which is very unsafe and if the vehicle is applying emergency braking when no objects are present it is very dangerous and concerning to even drive the vehicle, especially at highways speeds when other traffic is present. GM’s service bulletin acknowledges there is an ‘anomaly’ with some of their blind zone sensors and ALL vehicles exhibiting these unsafe conditions need to be fixed before causing an accident.

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.

The driver-side front door and related body fit/sealing system appear to be defective. The door is visibly uneven and misaligned with the surrounding body panels, resulting in excessive door gaps and significant air intrusion into the cabin while driving. The condition is available for inspection upon request, and photographs and videos documenting the issue are available. The excessive air intrusion creates substantial wind noise and driver distraction while operating the vehicle at highway speeds. The misaligned door also raises concerns regarding proper door sealing, structural fit, weather protection, and occupant safety in the event of an accident. A vehicle of this age and condition should not exhibit such defects. The condition is consistently reproducible during normal driving, particularly at highway speeds where excessive air enters the cabin through the driver-side door area. (If applicable, add: "The vehicle has been presented to an authorized Chevrolet dealer for inspection.in FH dailey chevrolet San leandro, they replaced weather strip, but air is more then what it was before, they declined my service and told me to take the vehicle where I purchased from in epic chevrolet Sacramento. No vehicle is not inspected by anyone. No warning lamps or diagnostic messages were displayed. The primary symptoms were visibly uneven door alignment, inconsistent door gap measurements, and noticeable air intrusion and wind noise while driving. These symptoms were first observed shortly after taking delivery of the vehicle and have persisted since that time.
