Owners describe a cluster of electrical gremlins centered on the radio/infotainment unit. The stereo makes loud, sudden pops and screeches, sometimes so abrupt drivers report nearly losing control. When it happens, the display flickers or goes dark, the turn signal chime fails, and heat/AC controls stop responding. Some owners say the radio won't recover until the engine shuts down and restarts. Triggering events include using turn signals, hitting brakes, opening doors, or closing windows—meaning the failures happen even while parked.
A second major issue is the ignition key getting stuck or refusing to release. Owners have to cycle the shifter repeatedly between park and drive to free it. One ASE-certified tech notes this appears tied to a Body Control Module (BCM) fault. Several report burning smells and one documented vehicle fire with burnt console wiring. Two owners mention the vehicle shutting off without warning while driving at highway speeds, including one who lost power steering.
A third failure pattern involves the ignition switch itself. Owners report the key shifting to accessory mode unexpectedly during normal operation or even from light knee contact, killing the engine mid-drive. The recall remedy—replacing the switchblade key with a standard key—backfired for some; the steering wheel paddle shifter still contacts the key during turns, breaking it or shutting the engine off.
Multiple owners note these issues affect entire electrical subsystems and quote repair estimates ranging from $600 to $1,000+. Several cite online forums and YouTube videos showing the same failures across model years 2011–2015, yet no recall has been issued for the radio failures or secondary electrical faults.
Failure modes owners describe
Radio/infotainment unit popping, screeching, and intermittent shutdown
Stereo produces loud pops, screeches, or crackling sounds and shuts off at random intervals. When it fails, the display flickers or goes completely dark. Recovery often requires engine restart. Failures triggered by turn signals, brake application, window operation, door opening/closing, rear defrost activation, or occur without any user input.
When: Typically begins 25,000–40,000 miles; some owners report onset as early as under 5,000 miles; continues to escalate over time
Symptoms owners cite: Loud pop or screech from speakers; Radio volume uncontrollable or muted; Display screen flickers or goes blank; Station tuning or volume controls unresponsive; Simultaneous loss of turn signal chime audio; Heat/AC control panel lights flicker or shut off; Correlated failures in navigation, OnStar, and Bluetooth; Radio may function briefly via AUX only at lower volume after malfunction
Codes mentioned: P0300 or similar sensor/ignition-related codes reported on some diagnostics, Two fault codes found on one 2011–2015 model (specific codes not named)
Repairs/costs cited: Dealers have recommended radio replacement ($700–$1,000) and software updates; one technician cited possible white wire clip behind radio as user remedy; BCM reprogramming mentioned; replacements with OEM radio have recurred
Recalls/TSBs owners mention: GM initially stated insufficient complaints to warrant recall; later offered diagnostic appointments at owner cost; no recall issued; one dealer confirmed this as a known issue for 2011–2015 models but stated OEM radio replacement as only repair path
Ignition key stuck in ignition or accessory position; key release failure
Key becomes stuck and cannot be rotated to the lock position or removed. Owners must cycle the gear shifter multiple times between park and drive, or manipulate the key forcefully, to free it. One owner had the shifter assembly replaced, confirming electrical/mechanical linkage failure. Some report the key locking up even when turning to run position.
When: Reported from as early as 8,100 miles; affects vehicles with 20,000–55,000+ miles; ongoing after ignition recall
Symptoms owners cite: Key stuck in accessory position; Key refuses to rotate to lock position; Requires multiple shifter manipulations or hard pulling to extract key; Battery drain due to extended accessory/ignition state; Car unable to shut off completely with key in ignition; Locking up occurs both when shifting and at rest
Repairs/costs cited: Shifter assembly replacement cited at ~$600–$1,000 after tax; dealers have ruled failures as electrical/trim and denied warranty coverage beyond mileage thresholds
Recalls/TSBs owners mention: Ignition recall 14V346 issued August 2014; owners report recall repair did not resolve key-release problems; some dealers blamed shifter assembly (not covered under recall) and charged for repair
Ignition key inadvertently shifting to accessory or off during driving
Key rotates or moves from the run position to accessory or off without driver input, typically triggered by light contact (knee, paddle shifter, vibration) or during turns. Engine shuts off mid-drive. Post-recall remedy (standard key to replace switchblade) has failed; steering wheel paddle shifter still contacts the key during hard turns, breaking it or killing the engine.
When: Reported from as low as 800 miles and up to 80,000+ miles; recurring post-recall
Symptoms owners cite: Engine light illuminates; Engine shuts off suddenly while driving; Steering wheel seized or becomes stiff; Loss of power steering; Key broken by paddle shifter contact during turns; Engine must be manually restarted in park
Repairs/costs cited: Replacement standard key supplied by recall; owners report paddle shifter still breaks it; no effective remedy cited
Recalls/TSBs owners mention: Ignition recall 14V346 applied; offered standard key and keyless-entry fob replacement; remedy inadequate per owner reports
Broad electrical system shutdown: radio, speedometer, tachometer, turn signals, HUD, display
Multiple electrical components fail simultaneously while driving: radio, turn signals, speedometer, tachometer, heads-up display, and climate controls go offline without warning. Vehicle continues to run and respond to throttle and steering, but driver loses critical instrumentation and signal capability. Failures may last seconds to minutes and recur.
When: Reported at 48,000–122,000 miles; one instance at highway speeds (55 mph)
Symptoms owners cite: Speedometer and tachometer stop working; Turn signals and turn signal audio cease; Radio shuts off; Heads-up display goes dark; Climate control stops responding; Dashboard lights flicker or go out; Service theft deterrent, airbag, parking assist, tire monitor warnings illuminate; Rear passenger window control inoperable; convertible top non-functional
Codes mentioned: Service Theft Deterrent System warning, Service Airbag warning, Service Parking Assistant warning, Service Tire Monitor System warning
Repairs/costs cited: Dealers informed owners hardware failure not cost-justified due to vehicle age; one owner self-diagnosed insufficient ground wire thickness and added secondary ground; no repair completed
Recalls/TSBs owners mention: No recall; one dealer stated hardware failure not worth repair; manufacturers stated no recall available or referred to diagnostic services at owner cost
Cold-start electrical component failure: radio, climate, display, phone controls inactive until warm
On cold mornings, radio, climate control, instrument display, turn signal audio, and steering wheel phone controls do not power on. Systems activate only after 10–15 miles of driving as engine warms. One owner (ASE tech) cited white wire clip and BCM replacement as suggested fixes; dealer replacement of vehicle-specific BCM required.
When: Cold weather mornings; one report mentions typical wake-up at 10–15 miles driven
Symptoms owners cite: Radio powered off; Climate control inactive; Display shows no time/information; Turn signal clicking audio absent; Steering wheel phone controls unresponsive; Headlights may dim; Defrost unavailable when needed most
Repairs/costs cited: Online sources cite white wire clip behind radio as workaround; real fix reportedly BCM replacement and dealer-only programming of vehicle-specific module
Recalls/TSBs owners mention: No formal response cited; owner references online forums for troubleshooting
Vehicle fire and burnt console/center console wiring
Two owners report vehicle fire. One occurred while parked, with loud noise and flames; fire department extinguished. Another reports front center console and all wiring completely burnt while vehicle was unoccupied, causing black smoke throughout cabin, no flames visible, fire department extinguished interior. Both vehicles remain unrepaired.
When: Failure mileage reported as 36,800 miles (console fire); first fire mileage not stated
Symptoms owners cite: Loud noise from parked vehicle; Visible flames (first incident); Burnt console and wiring; Black smoke filling cabin; Vehicle stalled without warning on separate occasion (in second report)
Repairs/costs cited: Neither vehicle repaired; fire department called to extinguish
