2026 Chevrolet Suburban problems, recalls and owner complaints

Second row door lock/unlock buttons do not function properly. The vehicle may be locked from this position but is unable to be unlocked. This allowed a small child in a car seat to lock themselves in the car but unable to unlock the vehicle using the corresponding button on the door. This is a serious issue which left the child trapped and required rescue from the fire department. This is a known issue for all GM/Chevy SUV from model year 25&26

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…

While exiting the highway my vehicle suddenly lost power and could not move. I could not put the vehicle in neutral. The engine had completely seized. As a result, my car got hit by a Semi-truck.

While driving, suddenly began hearing loud knocking noise and lost most power. Was able to get vehicle off road, where it stopped, and had trouble starting again. Towed to dealer. Diagnosed issue as spun rod bearing.

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…

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…

Car shut off in the middle of the road while driving and auto braked. Had to get a tow. Dealership said engine is bad now.

Today, 5/2/26 in Lewis Center, OH- My daughter and I were returning home from her Soccer game. The time was about 11am. We were in my brand new Chevy Z71 Suburban, with 4,100 miles. As we were slowing , approaching the roundabout, i noticed no power as i was preparing to enter the roundabout. I then see that the car powered off. It would not restart and i had no way to put into N. I had to call [XXX] to have the Sheriff direct traffic. I used Onstar, only to find out the tow was 216 min out. So the Sheriff called a tow and it was there in 30 min and towed to local Chevy dealership, thankfully…

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…
