What stands out
Owners have filed 38 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Electrical accounts for 26% of all owner complaints filed against this vehicle, across 10 categories tracked.
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.
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 describe a defective ignition switch that causes multiple cascading failures. The most critical: vehicles stalling without warning at highway speeds (25–65 mph), killing power steering and brakes instantly. Two owners report nearly being hit by trucks; another crashed into a ditch. A few lost engine power at 30–50 mph in normal driving or while sitting idle. Restart after stalling works, but owners report the failures recurring across multiple trips.
The ignition switch itself jams in start mode or won't accept the key all the way in, forcing repeated jiggling to position it correctly. Keys get stuck and won't come out. Dealer techs have noted loose or defective connections inside the steering column wired to the body control module (BCM).
Electrical cascades follow: horn fails intermittently, dash gauges stop working (tapping the dash brings them back), climate controls reset unprompted, clock jumps time, and warning lights flash abnormally—ABS, StabiliTrak, check engine all illuminate together. One owner reports the "Reduce Engine Power" message followed by shutdown. Two fires occurred under the hood: one melted fog-light wiring and plastic housings; another ignited in the instrument panel area while the heater was on.
One OBD module failed completely, shutting the car off mid-drive. Battery diagnostics returned false positives, leading to unnecessary replacements. The 2014 recall (NHTSA 14V400000) was issued but parts remained unavailable for many months, and some owners report the recall remedy covers only the key, not the ignition source itself.

Failure modes owners describe
Ignition switch—stalling and power loss
Ignition switch fails without warning, cutting engine and killing power steering and brakes at speed. Vehicle stops responding to controls. Owner must wait and restart; failures recur on multiple occasions across different trips.
When: 25–65 mph highway driving; some at 30–40 mph city speeds; one while parked idle
Symptoms owners cite: Engine cuts off without warning while driving; All engine power lost mid-drive; Power steering fails—steering wheel locked up; Power brakes fail—brake pedal unresponsive; Vehicle unable to be controlled after stall; Restart possible after stall; failure recurs on multiple occasions
Repairs/costs cited: Owners did not cite specific repair costs. One owner had ignition replaced per dealer diagnosis but vehicle not repaired.
Recalls/TSBs owners mention: NHTSA Campaign 14V400000 (Electrical System) issued. Some owners were not notified. Recall parts became unavailable for extended periods; dealers could not schedule appointments or provide parts availability dates.
Ignition switch—key insertion and removal jamming
Key will not insert fully into ignition or becomes physically stuck and cannot be removed. Owners report key going only halfway in, requiring repeated jiggling over several attempts before it seats. Once stuck, key cannot be extracted without excessive force or locksmith assistance.
When: Intermittent over vehicle ownership; one case at 72,000 miles; another at 85,000 miles; one at 76,927 miles
Symptoms owners cite: Key enters ignition only partway, requires repeated attempts to seat; Key becomes lodged in ignition and cannot be removed; Excessive force required to extract stuck key; Key gets stuck in start mode and must be moved slowly back to RUN
Repairs/costs cited: One owner reported locksmith calls 'plenty of times' resulting in door dents that required repainting. Key replacement attempted but ineffective. No repair costs cited.
Recalls/TSBs owners mention: NHTSA Campaign 14V400000 issued. Manufacturer stated recall remedy covers key replacement only, not the ignition source. One dealer was unable to duplicate the failure.
Ignition switch—steering column connection failure
Loose or defective electrical connection inside the steering column, between the ignition and body control module (BCM), causes intermittent electrical dropout. Affects horn operation and likely contributes to broader electrical instability.
When: 33,000 miles at time of diagnosis; failures are intermittent
Symptoms owners cite: Horn works intermittently, only if pad pushed at an angle; Door locks and windows operate via remote but horn fails
Repairs/costs cited: Dealer diagnosed loose or defective connection inside steering column going to BCM. Vehicle was not repaired.
OBD module failure
On-board diagnostic module fails, causing immediate engine shutdown. Module replaced but does not resolve underlying electrical instability.
When: March 2006, during normal city driving
Symptoms owners cite: OBD fails during driving at normal speed; Car cuts off and locks up on roadway; Vehicle must be towed
Repairs/costs cited: OBD replaced at dealership.
Battery-related electrical dropout and false diagnostics
Vehicle loses all electrical power intermittently—accessories (radio, door locks, windows, trunk) operate via remote but engine will not start. Diagnostics incorrectly identify a bad battery, which is then replaced, but the true electrical fault remains. Suggests a deeper charging or power distribution issue.
When: March 2007; one case at approximately 113,000 miles
Symptoms owners cite: Vehicle cranks but will not start; Will not turn over; Radio, door locks, windows, trunk all operate normally by remote; Warning lights appear (ABS, StabiliTrak, check engine) after restart; Vehicle cuts off again after initial startup
Codes mentioned: Check ABS system, Check StabiliTrak system, Check engine light
Repairs/costs cited: Battery replaced per dealer diagnostics. Problem persists. No other repair attempted or cost cited.
Recalls/TSBs owners mention: Manufacturer refused buyback claim, stating issue had not recurred within one week of battery replacement—despite prior history of intermittent failures.
Electrical fire—fog light wiring and instrument panel
Melted wiring and plastic components in fog-light electrical system and instrument panel area ignite, creating flames and heavy smoke. Both fires occurred during normal operation (one while heater was activated; one after returning from grocery shopping with heater on).
When: One at 83,300 miles while driving at 40 mph with heater; one at unspecified mileage after short drive
Symptoms owners cite: Strong burning odor; Massive white smoke from instrument panel or under hood; Small flames visible under hood; Fog-light electrical system melted; Plastic light fixture housings melted
Repairs/costs cited: One fire extinguished by owner; one by fire department. One owner photographed melted components. Vehicle was not repaired; fire department intervention required.
Recalls/TSBs owners mention: Manufacturer was notified in at least one case.
Dashboard instrument cluster—intermittent failure
Gauges in instrument cluster stop responding to input, display does not update. Tapping the dashboard or hitting a bump temporarily restores function, then failure recurs. Suggests poor connector contact or intermittent power distribution to cluster.
When: Intermittent; one case at unspecified mileage
Symptoms owners cite: Gauge display stops working; Tapping dash temporarily restores gauges; Hitting a bump temporarily restores gauges; Gauges fail again after temporary fix
Repairs/costs cited: Vehicle was scheduled for repair but no outcome provided.
Climate control and interior electrical resets
Climate control system resets passenger compartment temperature setting unexpectedly. Clock loses time between parking and restart, jumping forward or backward. Suggests power interruptions or loose ground connections.
When: Intermittently across vehicle ownership; one case noted starting March 2006
Symptoms owners cite: Climate control temperature resets without user input; Clock time changes dramatically from parked state to startup
Repairs/costs cited: No repair attempted; owner reported issue persisted after OBD and battery replacement.
Horn intermittent operation
Horn fails to operate consistently; works only if steering wheel pad is pressed at an angle or not at all. Linked to loose steering column connection to BCM.
When: 33,000 miles
Symptoms owners cite: Horn works intermittently; Horn only operates if horn pad pushed at specific angle
Repairs/costs cited: Dealer diagnosed loose connection in steering column to BCM. Vehicle not repaired.
Reduce Engine Power message with shutdown
Dashboard displays 'Reduce Engine Power' warning and engine shuts down. Occurs on highway at 50 mph and while sitting at gas station. Mechanics and dealer unable to identify cause. Multiple GM owners report the same issue online.
When: Multiple occasions; at least one on 2/3/2016; one while vehicle parked at gas station
Symptoms owners cite: 'Reduce Engine Power' message appears on dash; Engine loses power and shuts down after message; Occurs at highway speeds (50 mph) and while parked
Repairs/costs cited: Mechanic and dealer unable to diagnose or repair. Vehicle owner reports keeping up on all maintenance.
Intermittent starting failure
Engine cranks but will not start on first attempt. Owner must turn the key many times, sometimes 5+ minutes of repeated attempts, before engine fires. Other times, vehicle starts immediately. Suggests intermittent fuel or ignition delivery.
When: Unspecified mileage
Symptoms owners cite: Vehicle will not start on first or second key turn; Requires many repeated key turns to start; Takes up to 5 minutes of repeated starting attempts; Other times starts right up without issue
Repairs/costs cited: No repair cited.
Multiple warning lights—ABS, StabiliTrak, check engine—simultaneously
ABS, StabiliTrak (stability control), and check engine lights all illuminate at the same time. Often accompanies stalling or electrical dropout events. Suggests a common power or ground failure affecting multiple modules.
When: March 2007 case; another unspecified
Symptoms owners cite: ABS warning light illuminates; StabiliTrak warning light illuminates; Check engine light illuminates; All three often appear together
Codes mentioned: Check ABS system, Check StabiliTrak system, Check engine
Repairs/costs cited: No repairs completed.
