A missing drivetrain component in the transfer case can cause the front and/or rear wheels to suddenly lock up without warning.
This page covers 8 recalls and 425 owner complaints for the 2015 Chevrolet Suburban.
Brake complaints dominate the 2015 Suburban's owner report profile, with 121 of 425 total complaints centered on the brake system. Owners consistently describe an unusual pedal feel, typically harder than expected or requiring noticeably more effort, even when brake components check out during inspection. Some report warning lights for the anti-lock brake system alongside stability control messages. Steering is the second most-reported system, with owners describing loss of steering response, sometimes accompanied by the vehicle shutting down while moving, HVAC cutting out, and multiple warning messages appearing simultaneously. The powertrain rounds out the top three, with owners reporting hesitation, rollback on inclines, and delayed engagement that feels abrupt when the vehicle finally moves. The brake pedal hardness complaints are particularly consistent, owners across multiple reports describe brakes that feel wrong even when conventional inspection finds no obvious fault.

By System
The 2015 Chevrolet Suburban has 8 recalls, the most serious being an ignition that can snap back to the "Accessory" position while driving, cutting engine power, power steering, and brake assist all at once.
Two separate recalls cover the electric power steering system: the steering assist can cut out suddenly, and on some vehicles it can drop out and then return with a jolt, both of which make the vehicle harder to control, particularly at low speeds. A transfer case defect can cause front or rear wheels to lock up unexpectedly, and a faulty driveline-protection sensor can trigger unintended braking on one side of the vehicle, pulling it sharply in that direction. These drivetrain and braking concerns only affect four-wheel drive models with specific axle and engine configurations.
On the safety equipment side, front airbags and seatbelt pretensioners may fail to fire in a crash, leaving the driver and front passenger without full restraint protection. The brake vacuum pump can also lose output over time, requiring more pedal effort to stop and extending stopping distances.
