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
Battery and starting problems plague this model across the board. Owners describe refusal to turn over, failed jump-starts, and low-voltage communication errors that trigger multiple warning lights and cap engine speed at 40 mph. One owner was towed five times over six years (2008–2014) for no-start conditions, with battery replacement failing to provide a lasting fix; another notes lights and radio staying on after shutdown, draining the battery. Intermittent engine stalling while driving is reported by multiple owners at speeds ranging from 20 to 65 mph with no warning—the engine simply quits and restarts unpredictably. Two owners explicitly state that identical ignition problems triggered recalls on other 2007 Cadillac models but not the STS, and one dealer confirmed the ignition switch is at fault; GM refused to cover the repair. One owner reports complete electrical system collapse at 4,000 miles—engine, hydraulics, and emergency systems all offline with zero forewarning. Voice command system frequently mishears commands, skips preset buttons, and volume spikes uncontrollably. One owner bought a demo with a dead battery and discovered the pre-delivery refresh was incomplete, then spent months chasing electrical gremlins with no resolution from dealers.

Failure modes owners describe
Battery drain and starting failure
Multiple owners report repeated no-start conditions requiring battery replacement or jump-starts. Some describe the vehicle refusing to turn over even with key fob in hand; others note the battery appears normal yet the car won't start or accept jumps. One owner was towed multiple times over several years (2008–2014) for this issue with no permanent fix found. Another notes lights and radio fail to shut off when the car is turned off, draining the battery.
When: Occurs intermittently throughout ownership; one owner reports incidents in 2008, 2010, 2011 (multiple), 2012, 2013, and 2014. Another reports failure at 300 miles and again shortly after.
Symptoms owners cite: Refusal to turn over; Vehicle won't accept jump-start; Multiple warning lights illuminate; Refusal to exceed 40 mph due to low voltage/low amps; Communication errors with multiple modules; Lights and radio don't turn off when engine shut off
Repairs/costs cited: Battery replacement performed multiple times (summer 2008, 2010, July 2011, February 2012, July 2013, March 2014). Ignition system checked and found OK. Key fob reprogrammed in 2012. One shop found battery normal but vehicle started with jump. One owner changed O2 sensors twice for unrelated check engine light.
Recalls/TSBs owners mention: Owner speculates 2007 STS may be included in GM Delphi system recall. No recall issued for this specific model per owner accounts. Dealer advised intermittent problems cannot be diagnosed without reproducing the fault.
Engine stall while driving (ignition-related)
Multiple owners report the engine randomly quits while the vehicle is in motion, at speeds ranging from 20 to 65 mph, with no warning. The engine restarts and runs for variable distances before stalling again. Two owners specifically state that a recall has been issued on other 2007 Cadillac models (but not the STS) for the same ignition problem. One dealer confirmed the issue is the ignition switch; GM refused to pay for the repair.
When: Occurs randomly at any speed; one instance at 105,000 miles. One report notes 'many occasions' of the problem.
Symptoms owners cite: Engine suddenly quits while driving; No warning before stall; Engine restarts and runs before stalling again; Check engine warning light illuminated (one case); Abnormal noise from vehicle (one case)
Repairs/costs cited: One vehicle had new starter and alternator installed; dealer could not diagnose. One dealer (Thompson Cadillac) confirmed ignition problem but repair not authorized by GM.
Recalls/TSBs owners mention: Recall issued on other 2007 Cadillac models for ignition switch but not on STS, per owner reports. GM refused to pay for repair on one documented case. Dealership unable to diagnose intermittent faults without reproduction.
Complete electrical system shutdown while driving
One owner reports total electrical system failure at 4,000 miles with no warning. Engine shuts off, hydraulic systems fail, emergency flashers inoperative, trunk inaccessible. Owner notes the vehicle had a new engine at 800 miles and that this electrical failure creates serious highway safety risk.
When: At 4,000 miles; no warning indicators before failure
Symptoms owners cite: Complete electrical system shutdown; Engine shuts off; Hydraulic systems fail; Emergency flashers do not work; No trunk access
Voice command system malfunction
Owner reports the voice command system mishears or misinterprets commands, or repeats the command correctly but fails to execute it. Preset buttons skip over first and sometimes second option when cycling through six presets. Volume periodically increases uncontrollably with no user input. Dealer states corporate is aware and working on a software fix.
When: Evident within first weeks of ownership (demo purchased with 3,500 miles)
Symptoms owners cite: Voice command mishears or misinterprets input; System repeats command but does not execute; Preset buttons skip positions; Volume increases uncontrollably
Recalls/TSBs owners mention: Dealer stated corporate is aware of the voice command issues and attempting a software fix.
Airbag cover defect with leaking adhesive
Owner reports the steering wheel airbag cover has leaking or oozing glue that has hardened on the outer surface, creating a visible defect.
Symptoms owners cite: Oozing/leaking glue from airbag; Hardened adhesive on airbag cover

Vehicle failed to start three times since purchased new and had complete shut off at highway speeds once. Since this is an intermittent problem, Cadillac dealer advised me that they cannot diagnose without reproducing problem. This is an unsafe condition and an unacceptable response from Cadillac. *jb
Engine randomly stops running while car is going at high speeds or low speeds. Engine will restart and travel for various distances before occurring again. This problem has been reported on many 2007 Cadillac and gm has made a recall on all 2007 Cadillac except the sts model ! It uses the same ignition switch as the other models. Very dangerous situation if another car is behind. *tr

It randomly causes the engine to die. An ignition recall has been issued on…
