This page covers 4 recalls and 40 owner complaints for the 2020 Chevrolet Suburban.
Powertrain and electrical issues dominate what 2020 Suburban owners report. On the powertrain side, owners frequently describe sudden loss of acceleration or complete stalling while driving, in some cases with no warning lights beforehand. A few owners report catastrophic engine failure, sudden onset of knocking or clicking followed by a complete loss of power, while others describe transmission problems, specifically a faulty solenoid that limits the vehicle to speeds around 40 mph. Electrical complaints center on intermittent failures across multiple systems at once, with owners reporting power steering and windshield wipers cutting out and then resuming without driver input. The combination of unexpected stalling and intermittent loss of steering is the most consistent thread running through these reports.

By System
The 2020 Chevrolet Suburban has 4 recalls, the most serious including a fuel system defect where a missing pressure regulator can crack the fuel pump, leak fuel, and raise the risk of a fire.
A brake-related recall affects certain vehicles equipped with a 5.3-liter engine, 3.08-ratio rear axle, and four-wheel drive: a faulty sensor can trigger unintended braking on one side of the vehicle, causing it to pull sharply in that direction without warning. On the drivetrain side, a transfer case defect in four-wheel and all-wheel drive models can cause front or rear wheels to lock up unexpectedly, raising the risk of a crash. There is also a tire concern: certain Continental tires fitted to these vehicles may have been over-cured during manufacturing, which can cause the sidewall to crack or the tread to separate, leading to sudden air loss while driving.
