full bulletin at NHTSA ↗This Preliminary Information communication provides information to the technician about vehicles that have an intermittent no crank, no start, or start stall concern with the security light coming on. Technician may find Diagnostic Trouble Codes B3055, B3060, and/or B3935. Technician should not replace any parts for this concern. If unable to duplicate the concern ask if the customer uses any Radio Frequency Identification Devices when the concern is present. Dealer should also direct their customers to the appropriate section in the Owner manuals that references that the device complies.
full bulletin at NHTSA ↗Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

The failure pattern owners describe
The 2010 Impala electrical system spawns a constellation of failures tied to wiring, switches, and sensor integration. The most common culprit is an ignition switch that sticks—the key won't turn to OFF, leaving the battery to drain overnight. Owners have had to disconnect batteries or pay dealers $600 or more; even then, parts for the official recall (14V355000) sat on backorder for months in 2014.
Passenger airbag sensors fail regularly. The warning light stays on; wiring under the seat gets torn and severed; the airbag deploys with the seat empty or fails to deploy in a crash. This defect allegedly recurs even after recall repairs, leaving owners paying diagnostic fees for a "fixed" problem.
Engine power loss is another pattern: traction control, engine-power-reduced, and throttle-disabled messages appear while driving, and the vehicle drops speed or stalls completely—sometimes on highways at 70 mph. Restarting temporarily fixes it. Throttle position sensors are often replaced, though success is hit-or-miss. One owner lost steering control during a power event.
Secondary failures compound the mess. Rear defroster harnesses burn without fuses to protect them. Dashboard lights delay or fail to light on startup, making night driving hazardous. HVAC blower motors and actuators fail in clusters—repair one and others follow. Battery corrosion, burnt connectors, and voltage drops signal deeper wiring decay.
Dealers struggle to diagnose intermittent faults. Multiple owners report being told parts aren't available, repairs can't be replicated, or that out-of-warranty owners must pay diagnostic fees—even for known recall issues.
