On XXX As I was driving after picking my kids up from school the vehicle started jerking and different lights came on in the dash.When I got home I told my husband and he called the dealership we bought it from and he was told for us to take them the truck so they can take a look at it. We are almost an hour away from the dealership.As we was driving in the highway about 40-45 mins into driving the truck started loosing power and a loud boom noise happened after the truck just cut off and my husband was able to safely pull over on the side of highway.When he opened the hood smoke was coming out and a weird smell started, he called [XXX] and fighter fighters checked it to disregard a fire.After we contacted the dealer again and they sent a tow truck to get the truck. They took the truck to the dealer but it was their closing time already by the time the tow truck was able to get to us. The truck is at the dealership Phillips Chevrolet at [XXX], at the moment we are still waiting. And now I have my [XXX] really scared of getting in vehicles and she’s scared of that truck because she says the truck almost caught on fire and she keeps saying she’s scared of us driving that truck again. That we are not safe anymore in the truck. And we as parent are concerned of her feelings and the way she doesn’t want to go in the truck again if it gets fixed. We are having a hard time trying to change her thoughts. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loss of motive power due to engine failure post recall remedy
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V‑274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V‑274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024.

What 2026 Chevrolet Suburban 1500 owners say
Most recent owner complaints, unedited.
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
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.
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.
The contact owns a 2026 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, an abnormal knocking sound was heard coming from the engine compartment, and the check engine warning light illuminated. The vehicle was driven to the contact's residence and parked. While reversing out of the driveway the following day, the engine seized, and the vehicle stalled. The vehicle was towed to a local dealer, where the cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 14,800.
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 contact owns a 2026 Chevrolet Suburban. The contact stated that while driving approximately 45 MPH, there was a popping sound coming from the vehicle and the vehicle stalled. The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 1,700.
