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. The vehicle was taken back to the residence, and upon exiting the vehicle, the contact noticed loose cables. The contact's husband plugged the cables back into place. The failure persisted, and the vehicle remained at the residence unrepaired. The contact had not driven the vehicle due to safety concerns. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

The technical service bulletin for the Service Safety Restraint System is for models 2021-2023. I have a 2020 Service Safety Restraint System error code this is appearing intermittently. Turning off and on. It's almost like a short somewhere. We are taking it in for servicing but I feel that the service bulletin should include the 2020 model as well.

Is 44 complaints a lot? They were filed between 2020 and 2026, roughly 7 a year, which is fewer than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2020 has 44 complaints on file, fewer than the 2019 (78) and fewer than the 2021 (194). Of the 15 model years of the Chevrolet Suburban we cover, the 2015 has the most (428). Older model years have had longer to collect complaints.
