What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
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
Owners of 2007 Pontiac G5 models describe a pattern of electrical failures centered on the ignition system. The most serious: key sticks in the ignition or won't fully engage, causing the engine to stall unexpectedly while driving at highway speeds. When this happens, power steering and power brakes fail. At least two owners reported crashes as a result. Dealers identified ignition switch and BCI (body control interface) faults; the manufacturer issued recall campaign 14V04700, but parts remained unavailable months after recall notices went out, leaving owners stranded.
Beyond the ignition, owners report erratic dashboard warning lights—check engine, power steering, anti-theft—illuminating simultaneously without obvious cause. One owner described the car acting as if accelerating and braking at once with no ability to steer. Diagnostics point to engine control module malfunction. Cooling fans run excessively after shutdown, draining batteries and preventing starts. Door locks fail intermittently. Air bag and seat belt warning lights stay on. Brake lights lag noticeably. One owner's trunk and electric start quit after dealer service work on the accelerator pedal, with the dealer blaming the customer.
The common thread: failures occur across mileage ranges and persist even after warranty expires, leaving owners to cover repair costs themselves.

Ignition switch sticking/failure
Key stuck in ignition or unable to turn fully to start position. Some vehicles stalled when key stuck. Owner narratives reference GM nationwide ignition switch recall campaign.

Symptoms owners cite: Key will not come out of ignition cylinder; Key cannot be fully inserted to start position; Engine stalls while key stuck in ignition; Vehicle loses power on highway after stalling
Repairs/costs cited: Dealer service bulletin 09-02-35-005B dated February 4, 2010 addresses key stuck issue; owners report out-of-warranty repair costs ($45 diagnostic fee mentioned); replacement of ignition cylinder and BCI module needed per service records
Recalls/TSBs owners mention: NHTSA campaign 14V04700 (ignition switch recall); parts unavailable at dealerships for months despite recall issuance; some vehicles still not covered under recall eligibility
Unintended power loss and stalling while driving
Vehicle loses engine power and stalls without warning during highway or city driving. Owner reports loss of power steering and braking on impact, raising safety concerns. Multiple owners report ignition switch fault as root cause.
When: Reported between 5,000 and 80,000 miles; several incidents on highways at 35–70 mph
Symptoms owners cite: Engine stalls or shuts down unexpectedly; RPM gauge drops to zero; Loss of power steering; Loss of power braking; Vehicle unable to be steered; Crashes reported due to loss of control
Repairs/costs cited: Diagnostic testing indicated ignition switch fault; towing required; out-of-pocket towing and rental costs cited by owners; one owner noted timing chain replaced twice prior to this issue
Recalls/TSBs owners mention: Ignition switch recall campaign 14V04700; manufacturer notified but vehicles not yet repaired due to parts shortage
Dashboard warning lights illuminating simultaneously/erratically
Multiple warning lights (check engine, power steering, anti-theft) illuminate at once without corresponding fault conditions. Occurs intermittently while driving. Engine control module suspected as root cause.
When: No specific mileage cited; occurs randomly during highway and city driving
Symptoms owners cite: Check engine light on continuously or flashing; Power steering warning light on; Anti-theft light on; All gauges act erratically; Vehicle behaves as if accelerating and braking simultaneously; Loss of steering control when lights illuminate
Codes mentioned: Multiple electrical system error codes per diagnostic scan
Repairs/costs cited: Diagnostic testing showed computer (engine control module) not operating correctly; one owner replaced battery due to bad cell, which temporarily reduced error codes; dealers unable to identify root cause during inspections
Recalls/TSBs owners mention: No recall issued for this symptom; owner reports knowing of numerous other affected vehicles online
Cooling fan running after engine shut-off
Engine cooling fans engage and continue running 15–20 minutes after vehicle is shut off, regardless of actual engine temperature or run time.
When: Early indication of broader electrical system degradation; followed by battery drain and no-start condition
Symptoms owners cite: Cooling fans run 15–20 minutes after engine shut-off; Battery drained due to prolonged fan operation; Vehicle will not start due to battery drain
Codes mentioned: Multiple electrical system error codes
Repairs/costs cited: Owner replaced battery due to bad cell; diagnostic showed engine control module operating incorrectly

What owners are reporting 1 most recent
My vehicle was one in the ignition switch recall. However, since I bought the vehicle ever so often and more and more the gauges will go crazy all lights (check engine, power steering, antitheft, etc) will all go on at once! This happens as I am driving it and without warning (on the highway, or just driving in the city). The car acts as if I am pressing the gas and brakes at the same time and I…

Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
