Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine 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 Service Information Bulletin provides the Service Manual Correction to the diagnostic procedure for DTC B2A16 (Immobilizer Key Collation Diagnosis).

The failure pattern owners describe
Owners of this model describe sudden complete engine shutdown while driving—mostly at highway speeds—with zero prior warning. The engine simply dies; one owner was doing 85 mph, another 35 mph in town. Dashboards stay dark; check engine lights appear only after the car stops. Some owners report the engine restarts later with no trouble, while others cannot restart until hours pass. Dealerships cannot replicate the failures or find any codes to work with.
A separate issue appears in multiple complaints: oil mixing into the coolant system, pointing to head gasket failure. One owner found a disconnected radiator hose and oil in the radiator at 75,000 miles. Another complains of leaking oil entering coolant across multiple repair attempts.
Owners also report intermittent engine idle-drops during acceleration—the engine RPM suddenly sags for 1–3 seconds right after pressing the gas, then power returns. This repeats in clusters over days, vanishes for weeks, and comes back. One owner experienced this from day one of ownership.
Post-incident acceleration hesitation and a keyless ignition button that stops working intermittently round out the pattern. In one case, dealership mechanics actually saw the stall happen but still could not identify the cause after 20+ days in the shop. The consistent thread: Subaru's diagnostic procedures are not catching these failures.

Failure modes owners describe
Complete engine shutdown while driving—no prior warning
Engine loses all power without dashboard alerts or check engine lights before shutdown. Vehicle becomes undriveable; owners report shutdown at highway speeds, in traffic, and low-speed city driving. Dealership diagnostics typically find no fault or cannot replicate.
When: Without clear pattern; some incidents after 1–2.5 hours highway driving, others random. One case at 200 miles on new vehicle.
Symptoms owners cite: Engine complete power loss while operating; No prior warning lights (except occasionally low fuel light); Check engine or battery light appears only after shutdown; Vehicle coasts to stop and will not restart, or restarts later without issue
Codes mentioned: Check engine light (code for running lean mentioned in one case), Battery light, Fluid light, Check Hybrid System error message
Repairs/costs cited: One case attributed to bad fuel by dealership; owner disputes. Most cases: dealer cannot replicate, no fault found. One case involved full engine replacement due to catastrophic internal failure (oil/coolant mixing).
Recalls/TSBs owners mention: Dealership unable to confirm faults or replicate in most cases. One dealership noted they 'often get cases they cannot replicate.' No recalls or TSBs mentioned.
Unexpected engine idle drop during acceleration
Engine RPM suddenly drops to idle for 1–3 seconds immediately after pressing accelerator pedal, causing brief loss of acceleration power. Occurs cyclically—several times over days, then clears for weeks or months before recurring. Present since new.
When: Intermittent, recurring pattern over vehicle lifetime. One case with ~21 pages of dealership correspondence; unclear total mileage.
Symptoms owners cite: Engine drops to idle 1–3 seconds after accelerator pressed; Power returns after delay; Hazard repeats several times over few days, then resolves for weeks/months; No warning lights reported; Worsened by cell phone EMI coupling
Repairs/costs cited: No components replaced by Subaru. Dealership states if mechanic cannot repeat, nothing can be done.
Recalls/TSBs owners mention: Dealership unable to repeat; no action offered over 21 pages of owner correspondence.
Intermittent stalling without warning
Engine shuts off unexpectedly while idling at traffic light or driving 35–40 mph, with no prior warning lights or sputtering. Vehicle restarts immediately or after brief wait without issue. Followed by intermittent keyless ignition start button malfunction (requires several attempts).
When: First occurrence at traffic light, second after week of problem-free driving at 35–40 mph.
Symptoms owners cite: Engine shuts off without sputtering or warning signs; No check engine light or dashboard alerts prior to shutdown; Vehicle restarts without problem; Subsequent keyless ignition push-start button unresponsive initially, green light appears after multiple attempts
Repairs/costs cited: Vehicle at dealer 20+ days. Dealership states problem has occurred multiple times with mechanic present, but cause cannot be determined.
Recalls/TSBs owners mention: No fix identified despite repeated dealer visits and mechanic observation of the failure.
Engine falter with high RPM and power loss on highway
Engine falters during acceleration on freeway; vehicle loses speed and produces high revving noise despite driver continuing to press accelerator. Requires continuation at very slow speed (<10 mph) to exit freeway.
When: While accelerating on I-405 freeway. Repeated next day at dealership.
Symptoms owners cite: Engine falter during acceleration; High revving noise; Loss of forward speed despite driver acceleration input; Vehicle requires slow-speed continuation to exit safely
Oil and coolant mixing—head gasket failure
Oil contaminates coolant system via head gasket failure. Radiator hose disconnects, temperature light comes on intermittently. Oil present in radiator indicates potential head gasket or engine replacement needed.
When: Detected at unknown mileage; one case at 75,000 miles. Another case: still unresolved as of April 21, 2021, after February 12, 2021 dealer service.
Symptoms owners cite: Temperature light comes on intermittently, then ceases; Disconnected hose between radiator and overflow tank; Oil visible in radiator; Fluid leak hazard
Repairs/costs cited: Head gasket replacement discussed; one case required full engine replacement. Another case remained unrepaired after 2+ months of dealer service.
Recalls/TSBs owners mention: Dealer identified head gasket as cause; no effective repair mentioned. One case unresolved after multiple repair attempts.
Oil leaking into coolant—multiple failed repairs
Oil contaminates coolant system; multiple dealership repair attempts fail to stop leakage. Fire hazard posed by oil fluid leaking.
When: Unknown; multiple repair cycles documented.
Symptoms owners cite: Oil leaking into coolant system; Leakage continues despite multiple repairs; Fire hazard risk
Repairs/costs cited: Multiple repairs attempted; source of leakage not definitively resolved.
Low-speed acceleration stalling feeling—post-incident
After the initial stall event, vehicle exhibits persistent low-speed acceleration hesitation and feeling of impending stall when pressing gas pedal, though actual stall does not occur. Dealership unable to repeat despite multiple visits.
When: Post-incident; ongoing at time of complaint.
Symptoms owners cite: Acceleration hesitation at low speeds; Feeling of imminent stall when pressing gas pedal; No actual stall occurring
Repairs/costs cited: No fix identified despite multiple dealership visits.

What owners are reporting 2 most recent
While driving at normal operating speed, the vehicle experienced a sudden and complete loss of engine power with no prior warning. There were no dashboard alerts, warning lights, or check engine indicators before the failure occurred. The vehicle became immediately unsafe to operate and had to be pulled over in a main highway center lane divide. After inspection by a licensed mechanic, it was…
Engine stalled without warning while driving on highway: I had been driving for about an hour and a half when my low fuel warning light came on, which meant I still had 70 miles left until empty. Almost immediately after, while driving on the highway in the middle lane, my engine made a revving noise and my car lost power (pressed gas pedal, but nothing happened). Prior to that, the car drove…
